Will your aircraft fit — and how big does the door have to be?
Set your hangar size, then drag your aircraft and a door onto the floor plan. Clear span — no interior posts. Real wingspans, live clearances, and the door clear width and clear height your airplane actually needs.
Aircraft dimensions are published manufacturer figures except where marked unverified — verify any of them against your own type certificate data sheet before you order. Door clear width allows 3′ past each wingtip, clear height 1′ above the tail. These are minimums, not comfortable numbers. Non-aircraft footprints are planning estimates.

⚡ Quick Answer: What Aircraft Hangar Size Do You Need?
A single-aircraft metal post-frame hangar typically lands between 50×50 and 60×60, and a finished 60×60 metal post-frame aircraft hangar runs $92,000 to $212,000, or roughly $26 to $59 per square foot depending on door type, slab thickness, and site conditions. The critical point is that aircraft hangar size is decided by wingspan and tail height, not by the length most owners picture. A Pilatus PC-12 clears a 50 ft wide bay on span and fails a 12 ft door outright on height. Use the aircraft hangar layout planner above this article to drop your actual airplane into a scaled floor plan before a single dimension gets committed to a quote.
Almost every undersized hangar was sized the same way: the owner looked up the airplane's length, added a comfortable margin, and picked a round number. Length is the figure a pilot can picture. It is almost never the figure that decides the building. Wingspan sets how wide the door has to be. Tail height sets how tall it has to be. Get either one wrong and the airplane does not go in the building, regardless of how much floor area you bought.
The inversions are constant once you start comparing real numbers. A Diamond DA62 is shorter than a Cessna 182 is long, and nearly ten feet wider than a Beechcraft Baron. A Cessna Caravan at 52 ft of span needs more door than a Citation M2 at 47 ft, even though the jet is the bigger, faster, more expensive airplane. Choosing aircraft hangar size off a mental image of the aircraft produces a building that is wrong in at least one dimension more often than it produces one that is right.
Those mistakes are permanent in a way nothing else about the project is. You can add insulation later, upgrade lighting, pour an apron, finish an office. You cannot move a sidewall two feet and you cannot raise an eave once the trusses are set. This guide gives you the published span, length, and tail height figures for the aircraft most owners are actually hangaring, the door sizes that clear them, and a full cost breakdown for a 60×60 metal post-frame hangar. Run your airplane through the aircraft hangar layout planner at the top of this page, then use the tables below to sanity-check what it tells you.

How the Aircraft Hangar Layout Planner Sizes Your Building
The planner returns exactly four numbers, because those are the four numbers a metal post-frame builder needs to quote a hangar: door clear width, door clear height, hangar depth, and clear height. Everything else on the quote follows from those. The clearances built into each figure are conservative planning minimums, not a published standard:
| Figure | How It Is Computed | Clearance Applied |
|---|---|---|
| Door clear width | Widest wingspan in the hangar + clearance each side | 3 ft past each wingtip |
| Door clear height | Tallest tail + clearance above | 1 ft above the tallest tail |
| Hangar depth | Longest aircraft + nose clearance + tail clearance | 5 ft nose, 5 ft tail |
| Clear height | Tallest object in the building plus its own allowance | Varies by item |
Worked through on a single Pilatus PC-12, the planner returns 59′5″ door clear width, 15′0″ door clear height, 57′4″ depth, and 15′0″ clear height. That is a 60×60 metal post-frame aircraft hangar with a 60×18 door, which is exactly why that combination is so common on general aviation fields. Each figure names the aircraft driving it, so a mixed fleet shows immediately which airplane is setting which constraint — often the small one sets the width and the big one sets the depth.
Warnings Stay Silent Until You Place a Door
The planner does not nag about a door you have not chosen yet. Once one is placed, it flags tail height against door clear height and wingspan against door clear width in red, marginal fits in amber, and an opening wider than the wall it sits on in red. It also separates two problems most tools conflate: an airframe past a wall is red, but clearance past a wall is amber — that layout physically works, you simply cannot taxi the aircraft out of it.
What the Aircraft Hangar Layout Planner Does Not Do
It is two-dimensional. Heights are computed and reported, never drawn. Nothing is rendered in three dimensions — for that, take the four figures into the 3D building designer.
It is not a code compliance tool. It says nothing about NFPA 409 hangar classification, fire suppression, occupancy, or egress, and it should not be treated as checking any of them.
It does not model wing-over-wing overlap. Aircraft interlock in plan — shapes passing each other without touching. One wing sitting above another requires wing height above ground, which most spec sheets omit, so it is not built.
It does not price anything and it is not an engineering document. It does not replace a builder, an A&E firm, or your airport authority. Nothing it produces is certified, approved, or guaranteed to fit.
Why Metal Post-Frame Is the Right Structure for an Aircraft Hangar
A metal post-frame hangar carries its roof load on steel columns spaced 8 to 12 ft on center with engineered trusses bearing on top. There are no interior posts. On a 60×60 building that is 3,600 sq ft of genuinely unobstructed floor. This matters more in a hangar than in any other building type, because a hangar with a post in it is not a hangar — a wing does not go around an obstruction, and a tug operator cannot improvise a path.
The second structural advantage is the sidewall. Metal post-frame walls run vertical to the eave. That sounds trivial until you remember that a wing does not taper: a 53 ft PC-12 span needs 53 ft of clear width at wingtip height, not at floor level. Curved-wall and arch structures give you their nominal width at the centerline and steadily less as you move outward, which is precisely where the wingtips are. Correct aircraft hangar size is a function of usable width at wing height, and vertical walls deliver all of it.
Third is door flexibility. Openings in a metal post-frame hangar are framed between existing columns, so a 60 ft or 70 ft bi-fold is a straightforward specification rather than a custom engineering exercise. That single property drives the cost separation between metal post-frame and rigid-frame alternatives at general aviation hangar sizes.
Aircraft Hangar Size by Aircraft: Wingspan Decides the Building
Below are published manufacturer figures for the aircraft in the planner catalog, sorted by span, because span is the number that sets your door and therefore your aircraft hangar size. Five entries are marked unverified — three rotorcraft whose manufacturers publish nothing reachable, and two warbirds that have had no manufacturer for eighty years. Their figures come from encyclopedias, brokers, and museum collections rather than a factory spec sheet, and saying so is more useful than a longer list that quietly launders its sources. Always confirm against your own aircraft's documentation before ordering.
| Aircraft | Wingspan | Length | Tail Height | Minimum Door Clear Opening |
|---|---|---|---|---|
| Beechcraft Bonanza G36 | 33.5 ft | 27.5 ft | 8.58 ft | 39.5 × 9.6 ft |
| Piper Archer (PA-28) | 35.5 ft | 24.0 ft | 7.25 ft | 41.5 × 8.3 ft |
| Cessna 182 Skylane | 36.0 ft | 29.0 ft | 9.33 ft | 42.0 × 10.3 ft |
| Cessna 172 Skyhawk | 36.08 ft | 27.17 ft | 8.92 ft | 42.1 × 9.9 ft |
| P-51D Mustang ⚠ unverified | 37.0 ft | 32.0 ft | 12.0 ft | 43.0 × 13.0 ft |
| Beechcraft Baron G58 | 37.83 ft | 29.83 ft | 9.75 ft | 43.8 × 10.8 ft |
| Cirrus SF50 Vision Jet | 38.7 ft | 30.7 ft | 10.9 ft | 44.7 × 11.9 ft |
| F4U Corsair ⚠ unverified | 41.0 ft | 33.0 ft | 15.0 ft | 47.0 × 16.0 ft |
| Daher TBM 960 | 42.10 ft | 35.22 ft | 14.29 ft | 48.1 × 15.3 ft |
| Piper Malibu (PA-46) | 43.0 ft | 30.0 ft | 11.25 ft | 49.0 × 12.3 ft |
| Daher Kodiak 100 | 45.0 ft | 33.8 ft | 14.7 ft | 51.0 × 15.7 ft |
| Cessna Citation M2 | 47.25 ft | 42.58 ft | 13.92 ft | 53.3 × 14.9 ft |
| Diamond DA62 | 47.75 ft | 30.17 ft | 9.25 ft | 53.8 × 10.3 ft |
| Cessna Caravan 208 | 52.08 ft | 37.58 ft | 14.83 ft | 58.1 × 15.8 ft |
| Pilatus PC-12 | 53.42 ft | 47.3 ft | 14.0 ft | 59.4 × 15.0 ft |
Two Figures That Quietly Sell People the Wrong Building
The Piper is an Archer, not a Cherokee. PA-28 is a family whose members do not share a wingspan. The tapered-wing Archer is 35′6″; the older Hershey-bar Cherokee 140 and 180 are closer to 30 ft. Five feet decides whether a 36 ft wide bay works, so confirm the exact model on your registration rather than the family name.
The Corsair is listed spread-winged at 41 ft. It folds to roughly 17 ft. A folded span is precisely the number that sells someone a hangar too small to ever unfold in, and any warbird you intend to work on needs the spread figure.
Rotorcraft Dimensions
Rotorcraft are the one case where the height that matters for the door and the footprint that matters for the floor come from two different configurations. Heights below are static, blades stopped, which is the correct number for a door opening because a helicopter is rolled in with the rotor parked. The footprint stays rotors-turning, because that is the floor it occupies once it is inside.
| Rotorcraft | Rotor Diameter | Length (Rotors Turning) | Static Height |
|---|---|---|---|
| Robinson R44 ⚠ unverified | 33.0 ft | 38.2 ft | 10.9 ft |
| Robinson R66 ⚠ unverified | 33.0 ft | 38.3 ft | 11.5 ft |
| Bell 407 ⚠ unverified | 35.0 ft | 41.67 ft | 11.67 ft |
| Airbus H130 | 35.04 ft | 41.47 ft | 11.84 ft |
Recommended Aircraft Hangar Size by Aircraft Class
| Hangar Size | Square Feet | What Actually Fits | Typical Door |
|---|---|---|---|
| 40×40 | 1,600 sq ft | One light single — Archer, Bonanza, C172 — with a workbench along one wall. No room for a car and the airplane. | 40×14 bi-fold |
| 50×50 | 2,500 sq ft | One light single or light twin, plus a tug, a vehicle, and a small shop area. Comfortable for a Baron, Malibu, or SF50. | 50×16 bi-fold |
| 60×60 | 3,600 sq ft | One turboprop — PC-12, Caravan, TBM, Kodiak — or two light singles nested nose-in and nose-out, with room for a car and ground equipment. | 60×18 bi-fold |
| 60×80 | 4,800 sq ft | One turboprop plus a light single, or a light jet with a dedicated shop bay and parts storage behind it. | 60×18 bi-fold |
| 80×80 | 6,400 sq ft | Two turboprops nested, or a maintenance operation with lifts, a wash bay, and full ground support equipment. | 70×18 bi-fold |
These footprints are all comfortably within standard metal post-frame clear span. If you want to price a specific one, the 60×80 metal pole barn page covers that footprint in detail, and the pole barn layout planner handles the shop, vehicle, and equipment side of a mixed-use building.
Hangar Door Sizing: Quote the Clear Opening, Not the Rough Opening
Door width and height are where hangar buyers under-build more often than anywhere else, and the door is also the single largest line item on the quote. Every size in the planner and in the table below is the clear opening — the actual hole the airplane goes through. That is the number to give a supplier. Rough opening and structural opening are larger, and confusing the two is how an owner ends up with a 14 ft door where a 16 ft door was intended.
| Door Type & Clear Opening | Installed Cost Range | Clears |
|---|---|---|
| Bi-fold 40×14 | $12,000 – $22,000 | Bonanza, Archer, C172, C182, Baron |
| Bi-fold 50×16 | $17,000 – $30,000 | SF50 Vision Jet, TBM 960, Malibu, Kodiak 100 |
| Bi-fold 60×18 | $24,000 – $42,000 | PC-12, Caravan 208, Citation M2, DA62 |
| Bi-fold 70×18 | $32,000 – $55,000 | Two light singles side by side, larger turboprop class |
| Hydraulic one-piece 45×15 | $18,000 – $32,000 | Single turboprop; canopy shelters the ramp when open |
| Hydraulic one-piece 60×18 | $30,000 – $52,000 | PC-12, Caravan; fastest cycle time of any hangar door |
| Sectional overhead 40×12 | $6,000 – $13,000 | Light singles only — 12 ft eliminates every turboprop |
| Sliding 40×14 | $5,000 – $11,000 | Light singles; needs 40 ft of clear wall for the leaves |
| Sliding 60×16 | $9,000 – $18,000 | Wide singles and twins; needs 60 ft of clear parking wall |
| T-hangar 42×12 | $7,000 – $15,000 | Nested T-hangar bays, light aircraft only |
| Walk door 3×7 | $500 – $1,100 | Personnel access — put one on every hangar |
Tail Height Is the Most Expensive Miss in the Whole Project
Width failures are obvious on a drawing. Height failures are not, because tail height is the one figure nobody memorizes. A 12 ft door clears a Cessna 172 with room to spare and stops a PC-12, a Caravan, a TBM, a Kodiak, and a Corsair cold. A T-hangar bay at 42×12 looks generous on width and rules out most of the turboprop fleet before you have even measured the span. Set the door clear height from the tallest tail plus 1 ft, then set the eave from the door.
Sliding Doors Need Wall to Park On
A sliding door does not disappear when it opens — the leaves park on a run of wall beside the opening, and that run is roughly as long as the opening itself. A 60 ft sliding door therefore wants a 120 ft wall, which is why sliding is common on long sidewalls and rare on the 60 ft endwall of a square hangar. The planner draws that parking run, so an arrangement that cannot physically work shows up before it reaches a quote. Bi-fold and hydraulic doors need no wall run, which is the main reason they dominate hangars despite costing more.
Will Two Aircraft Fit? Interlocking, Rotation, and Real Silhouettes
This is the question a tape measure cannot answer, and it is where most sizing guidance quietly gives up. Aircraft nest. Park one nose-in and one nose-out and the wings pass between each other's wing and tailplane, so the pair occupies dramatically less width than the arithmetic suggests. The planner models that on the measured silhouette of each aircraft rather than on a bounding box, so the answer it gives is the honest one.
| Two Aircraft, Nose-In / Nose-Out | Real Silhouette Spacing | Treated as Rectangles | Width Recovered |
|---|---|---|---|
| Two Cessna 172 Skyhawks | 19.8 ft apart | 36.0 ft apart | 16.2 ft |
| Two Pilatus PC-12s | 37.3 ft apart | 53.5 ft apart | 16.2 ft |
| Two aircraft wingtip to wingtip | Full span each | Full span each | None — and correctly so |
The last row matters as much as the first two. Side by side with wings level, nothing is recovered and nothing should be — an airplane needs its span. Interlocking only pays when the aircraft are opposed, which is exactly why hangar depth and door width trade against each other and why the arrangement has to be drawn rather than assumed.
Rotation compounds the same effect. The corners of a rectangle are empty air, and that empty air is what makes bounding-box math wrong. Turned 45°, a Piper Malibu treated as a rectangle claims 10.6 ft of floor it does not occupy. A PC-12 claims 16.7 ft. That is the entire difference between a layout flagged as past the wall and one that is plainly clear of it, which is why the planner allows rotation to any whole degree rather than 90° steps.
The Car Is the Commonest Thing Nobody Plans For
A vehicle in the hangar is the single most frequently forgotten item, and it is why the depth figure so often comes up short. You drive to the airport, you park inside, the airplane comes out around the car. Add the car, the tug, the fuel cart, and the ground power unit to your layout before you settle on aircraft hangar size — the planner carries all of them, plus workbenches, tool chests, two-post and four-post lifts, compressors, parts washers, mezzanines, and office partitions.
Metal Post-Frame Aircraft Hangar vs. PEMB vs. Fabric-Covered Hangar
The three structures a general aviation buyer actually gets quotes on are metal post-frame, pre-engineered rigid-frame steel, and fabric over a steel arch or truss. Masonry does not appear here because nobody quotes a block hangar bay — concrete masonry shows up on an attached office or a fire-rated shop wall, not on the aircraft floor.
| Factor | Metal Post-Frame Aircraft Hangar | Pre-Engineered Metal (PEMB) | Steel Arch / Fabric-Covered |
|---|---|---|---|
| Shell cost / SF | $14 – $26 | $20 – $38 | $12 – $22 |
| Full build-out / SF | $26 – $59 | $38 – $75 | $22 – $44 |
| Max clear span | 80 ft standard, wider engineered | 150 ft+ | 60 – 300 ft |
| Construction timeline | 4 – 8 weeks | 10 – 20 weeks | 3 – 6 weeks |
| Foundation requirements | Steel columns on brackets or piers — point loads, no continuous footing | Continuous engineered footings, anchor bolts, and thrust restraint in the slab | Piers, ballast blocks, or a knee wall |
| Usable width at wingtip height | Full — vertical walls to the eave | Full minus the frame haunch at the knee | Reduced — the curve takes width exactly where wingtips sit |
| Door opening flexibility | Excellent — 60 to 70 ft bi-fold framed between existing columns | Good, but framed openings must be engineered up front | Limited — endwall geometry constrains the opening |
| Expansion ease | Excellent — add bays off the endwall | Moderate — requires matching frames | Moderate; some systems are relocatable |
| Insulation options | Deep girt cavity — blanket, batt, or closed-cell spray foam | Blanket or liner systems, limited cavity | Insulated liner only |
| Contractor availability | Very high | Moderate — specialized erectors | Limited |
| Service life of the envelope | 40+ years, coated steel panels | 40+ years, coated steel panels | Membrane 15 – 25 years, then replaced |
| Airport sponsor acceptance | Permanent structure, widely accepted | Permanent structure, widely accepted | Sometimes classed as temporary on leased land |
| Best for | Single to multi-aircraft hangars 40 – 80 ft wide | Very wide spans, crane loads, FBO and MRO complexes | Low-cost cover, very wide spans, short tenure |
The structural distinction is worth understanding because it explains the cost. A metal post-frame building is columns and trusses bolted together, so the load path runs straight down into isolated piers. A PEMB is a welded, tapered rigid frame with a moment connection at the knee, which is what lets it reach 150 ft spans — but that joint throws horizontal thrust into the base, which is why it demands continuous engineered footings and thrust restraint. You are paying for span capacity you do not need at general aviation aircraft hangar size. The economics flip somewhere around 80 to 100 ft of span, or as soon as bridge crane loads enter the picture.
Fabric competes on price and loses on the geometry that matters. Coated steel panel systems on metal post-frame and PEMB both document service well past four decades under normal conditions, while a tensioned membrane is a replaceable wear item. On leased airport land, some sponsors also treat fabric structures as temporary, which affects both your lease terms and your insurance.
Aircraft Hangar Cost: Full Breakdown for a 60×60 Metal Post-Frame Hangar
The reference building below is a 60×60 (3,600 sq ft) metal post-frame aircraft hangar with a 20 ft eave, one 60×18 bi-fold door with electric operator, one walk door, and a 6-inch reinforced slab. Low reflects straightforward site access in a low-cost labor market with modest loads; high reflects difficult access, heavy snow or high wind engineering, and premium finishes.
| Line Item | Low | Mid | High |
|---|---|---|---|
| Site prep, grading & apron subgrade | $3,000 | $7,000 | $12,000 |
| Foundation & 6″ reinforced slab | $21,600 | $32,400 | $46,800 |
| Steel columns, trusses & framing | $16,000 | $24,000 | $31,000 |
| Roof & wall metal panels | $11,000 | $16,000 | $21,000 |
| 60×18 bi-fold door + operator | $18,000 | $30,000 | $42,000 |
| Walk door, windows & ridge venting | $900 | $2,200 | $4,000 |
| Labor & erection | $16,000 | $26,000 | $34,000 |
| Electrical service & LED high-bay lighting | $4,500 | $9,000 | $14,000 |
| Permits, engineering & airport review | $1,200 | $3,400 | $7,000 |
| TOTAL — 60×60 | $92,200 | $150,000 | $211,800 |
| Cost per square foot | $25.61 | $41.67 | $58.83 |
Why a Hangar Costs More Per Square Foot Than a Shop of the Same Size
One line item explains most of it. The 60×18 bi-fold door is 20 percent of the mid-range build on its own. A comparable metal post-frame shop building takes a fraction of that on doors and a thinner slab, which is why per-square-foot figures borrowed from general pole building pricing consistently understate a hangar. When you compare quotes, compare the door line separately — it is where the spread between suppliers is widest.
Optional Upgrades
| Upgrade | Cost Range | Notes |
|---|---|---|
| Hydraulic door in place of bi-fold | +$6,000 – $12,000 | Faster cycle, single moving panel, shelters the ramp when open |
| 8″ slab with thickened edges | +$2 – $4 / sq ft | For jack points, lift anchors, and heavier turboprop point loads |
| Closed-cell spray foam insulation | $2.50 – $5.00 / sq ft | Best condensation control; also stiffens the panel assembly |
| In-floor radiant heat | $6 – $12 / sq ft | No overhead unit, no forced air on the airframe, no fuel-vapor concern |
| 200-amp electrical service | $4,500 – $12,000 | Cost driven almost entirely by distance to the nearest transformer |
| LED high-bay lighting package | $2,500 – $6,500 | Plan 12 – 16 fixtures for a 60×60, placed clear of wing sweep |
| Concrete apron, 60×40 | $14,000 – $30,000 | Flush transition to the taxilane; almost always required by the sponsor |
| Mezzanine office / crew room, 20×30 | $18,000 – $42,000 | Requires 20 ft+ eave and engineered floor loading |
| Wash bay drain with oil separator | $6,000 – $16,000 | Frequently a condition of an on-airport lease; check before you plan |
| Insulated steel liner panel | $3 – $6 / sq ft | Durable interior finish, easy to clean, reflects light |
| Gutters & downspouts | $9 – $16 / linear ft | Protects the slab edge and keeps ice off the door track approach |

Key Construction Details That Change Your Aircraft Hangar Size
Clear Height Is Not Eave Height
An 18 ft door opening requires roughly a 20 ft eave. Track, header, and structural framing consume about 2 ft above the clear opening, and that space is not negotiable. Buyers routinely order an 18 ft eave expecting an 18 ft door and end up with a 16 ft opening — enough to stop a PC-12 that needed 15 ft of clear height and had it on paper. Specify the door clear opening you need and let the supplier back into the eave height from there. This is the single correction that saves the most projects.
Concrete Slab and Point Loads
Slab thickness is a function of wheel loading, not building area. A 6-inch slab with rebar on 18-inch centers over 4 to 6 inches of compacted clean stone handles light singles through turboprops. Where a lift, a jack point, or a tug of any size is involved, thicken locally or step to 8 inches in that zone. Slope the floor gently toward the door so fuel, water, and melt run out rather than pooling under the airframe, and detail the apron transition flush — a lip at the door threshold is a nosewheel problem for the life of the building.
Condensation Control Is a Corrosion Problem, Not a Comfort Problem
In a hangar, moisture is not about comfort. Warm humid air meeting a cold steel roof panel condenses and drips directly onto control surfaces, hinges, and avionics bays. At minimum, install a condensation-control membrane or vapor barrier under the roof panels and pair it with ridge and eave venting so the assembly can dry. For heated hangars, closed-cell spray foam is the answer. Owners of aircraft with any magnesium or older aluminum structure should treat this as a primary spec, not an upgrade.
Lighting, Power, and Heat Placement
Plan 200 amps for any hangar with a compressor, welder, or maintenance bay; 100 amps is adequate for pure storage. Lay high-bay fixtures out against your actual layout so they sit clear of wing sweep — a fixture directly over the wing path gets hit eventually. Place outlets every 12 to 16 ft at 48 inches above the floor. If you heat, keep any suspended unit heater well above the tallest tail and confirm the clearance the manufacturer requires above fuel-bearing structure; in-floor radiant sidesteps the question entirely, which is why it is common in hangars despite the cost.
Permits, Airport Rules, and Ground Leases
A hangar answers to more authorities than any other metal post-frame building, and two of them can invalidate a design that is otherwise perfect. Local code applies as it would to any commercial structure, with model code language and jurisdictional adoption published by the International Code Council, but on an airport that is only the beginning.
NFPA 409 Classification Drives Suppression, and It Is Not Optional
Hangars are classified into groups by door height and single fire area, and that classification determines whether foam or other fire suppression is required. The thresholds are set out in NFPA 409, published by the National Fire Protection Association, and a system requirement can add a six-figure line to a project that never budgeted for it. This is decided by your authority having jurisdiction — not by any layout tool, including ours. Establish your classification with the fire marshal before you finalize door height, because door height is one of the inputs.
On Leased Airport Land, You May Not Own the Building at the End
Most on-airport hangars sit on ground leased from the airport sponsor, and improvements commonly revert to the sponsor when the lease term ends. A 30-year lease on a building with a 40-year envelope is a real financial fact, not a technicality, and it changes the entire build-versus-rent calculation. AOPA publishes guidance on hangar leases and tenant rights that is worth reading before you sign either the lease or the building contract. Read the reversion clause first, the term second, and the quote third.
FAA Review, Part 77, and the Airport Layout Plan
Height and siting near a runway are governed by imaginary surfaces defined in Part 77, and construction on or near an airport generally triggers notice to the FAA. On a federally obligated field, your hangar also has to be consistent with the approved airport layout plan, and the sponsor — not you — decides where it goes. Building on a private strip or in a residential airpark avoids most of this, though a through-the-fence agreement carries its own conditions; EAA maintains resources on airpark and private-field hangar construction worth reviewing early.
Regional Cost Differences
Wind and snow load engineering moves the frame cost, labor rates move the erection cost, and both vary sharply by region. The ranges below are for the same 60×60 metal post-frame aircraft hangar specified above.
| Region | Representative States | 60×60 Cost Range | Key Cost Driver |
|---|---|---|---|
| Southeast | FL, GA, AL, SC, NC, TN | $88,000 – $195,000 | Hurricane and high wind uplift engineering; exposed airfield sites; low snow load |
| Midwest | IA, IL, IN, OH, MO, MI | $92,000 – $200,000 | Moderate snow load; deepest metal post-frame supplier competition and best pricing |
| Great Plains | KS, NE, SD, ND, OK, TX Panhandle | $90,000 – $198,000 | High sustained wind loads; long material freight distances |
| Mountain West | CO, MT, WY, ID, UT | $105,000 – $232,000 | Heavy snow load driving truss upgrades; seismic in parts; high-altitude field access |
| Northeast | NY, PA, VT, NH, ME, WI | $110,000 – $245,000 | Highest snow loads and labor rates; frost depth requirements |

ROI: Build vs. Rent a Hangar
Build vs. Rent — 3,600 Sq Ft Over 10 Years
Renting: A T-hangar bay runs $250 to $600 per month in most markets, and a box hangar large enough for a turboprop runs $800 to $1,800. At $1,200 per month, that is $14,400 per year and $144,000 over ten years, paid out with nothing owned at the end. Hangar rents also rise faster than general inflation on constrained fields, and on many airports the waiting list is measured in years rather than months.
Building: A mid-range 60×60 metal post-frame aircraft hangar at $150,000 reaches breakeven against that rent at roughly 10.4 years. On owned land — a private strip, an airpark lot, or a through-the-fence parcel — you also hold a durable asset on a parcel at the end of it, and the metal envelope has decades of service life remaining.
The honest caveat: on leased airport land with a reversion clause, that asset value at the end may not be yours. If the lease term is shorter than the payback period, renting can be the better financial decision even though building is the better aviation decision. Model both, and read the reversion clause before you model anything.
Airframe depreciation avoided: this is the number that usually decides it. Sustained exposure degrades paint, interiors, seals, and avionics measurably faster, and outside storage is visible in a pre-buy inspection. On a $500,000 airframe, consistent hangaring commonly preserves 5 to 10 percent of resale value — $25,000 to $50,000 — against a building that cost $150,000. Add the corrosion work that does not happen and the case strengthens further.
Tax treatment: a hangar used in a trade or business is depreciable property, and accelerated or bonus depreciation may apply to qualifying structures. Personal-use aircraft storage is treated very differently. Talk to your accountant before you buy — the after-tax cost is frequently well below the sticker.

- The four planner figures — door clear width, door clear height, depth, and clear height, straight off your aircraft hangar layout planner drawing
- Complete aircraft list with span, length, and tail height — including anything you plan to buy, since aircraft hangar size is a thirty-year decision and your fleet is not
- Door type preference — bi-fold, hydraulic, or sliding, and the clear opening rather than the rough opening
- Land status — owned, ground lease, or through-the-fence, plus your airport sponsor contact if applicable
- Slab decision — thickness, any lift or jack point locations, and whether a wash bay drain is required
- Shop, office, or mezzanine requirement — this changes both depth and eave height
- Site address — suppliers price wind, snow, and seismic loads by county, and field elevation can matter
- Budget range — a real number lets suppliers specify appropriately instead of guessing at the door
Aircraft Hangar Size FAQ
A 40×40 metal post-frame hangar handles a Cessna 172 comfortably. The airplane is 36.08 ft of span, 27.17 ft long, and 8.92 ft to the top of the tail, which produces a required door clear opening of about 42 × 10 ft and a depth of roughly 37 ft with nose and tail clearance.
Step up to 50×50 if you want a vehicle, a workbench, and room to walk around the airplane without turning sideways. That extra bay is inexpensive relative to the door and is the upgrade owners regret skipping most often.
Take your widest wingspan and add 3 ft of clearance past each wingtip. That yields 42 ft for most light singles, 44 to 50 ft for twins and light jets, and 58 to 60 ft for turboprops like the Caravan and PC-12.
Specify the clear opening, never the rough or structural opening. Those are different numbers, and confusing them is how an owner ends up several feet short of the span they carefully measured.
Plan a 15 to 16 ft door clear opening, which requires a 17 to 18 ft eave once track and header are accounted for. A PC-12 stands 14.0 ft to the tail and a TBM 960 stands 14.29 ft, and the planner adds 1 ft above the tallest tail.
A 12 ft door — the standard T-hangar and sectional overhead size — will not clear either aircraft. Tail height is the figure that eliminates more hangars than any other, so check it first.
Often, yes, but only if they are opposed. Two Cessna 172s parked nose-in and nose-out clear each other at 19.8 ft apart on their real silhouettes, against 36.0 ft if you treat them as rectangles. Two PC-12s nest at 37.3 ft against 53.5 ft.
Side by side with wings level, nothing is recovered — an airplane needs its full span. This is exactly why the arrangement has to be drawn rather than calculated, and why nesting affects your aircraft hangar size more than any other single decision.
Longest aircraft plus 5 ft at the nose and 5 ft at the tail. A Cessna 182 at 29 ft needs 39 ft; a PC-12 at 47.3 ft needs 57.3 ft, which is why 60 ft deep is such a common turboprop dimension.
Then add for everything else that lives in the building. A car parked behind the airplane is the most commonly forgotten item and the most common reason a hangar that fits on paper does not work in practice.
Clear height is set by the tallest object in the building, not just the tallest tail. For light singles, 12 to 14 ft is sufficient. For turboprops, plan 15 to 16 ft. If you are installing a two-post or four-post lift, or a mezzanine, that item may set the number instead.
Remember that the door opening drives the eave: an 18 ft clear opening needs about a 20 ft eave. Height is cheap to buy at order time and impossible to buy afterward.
Bi-fold is the volume choice: lower installed cost at every width, proven mechanism, and it scales cleanly to 70 ft. Hydraulic one-piece costs $6,000 to $12,000 more, cycles faster, has a single moving panel, and forms a canopy over the ramp when open, which is genuinely useful for preflight in weather.
Sliding is the cheapest option by a wide margin but needs a run of clear wall beside the opening for the leaves to park on — roughly as long as the opening itself. That requirement rules it out on the endwall of most square hangars.
No, and it should not be described as doing so. The planner establishes footprint and computes the four dimensional figures a builder needs. It says nothing about NFPA 409 hangar classification, fire suppression, occupancy, egress, Part 77 surfaces, or airport layout plan consistency.
It is a 2D planning tool, not an engineering document, and its clearances are sensible planning minimums rather than a published standard. Confirm classification with your fire marshal, siting with your airport sponsor, and structure with a licensed engineer — then use the planner's aircraft hangar size figures to get accurate quotes.
