For a single-engine plane, you typically need a clear-span door about 40 to 50 feet wide and a footprint near 40×40 to 50×50 feet ‹confirm›, with a door height of 12 to 14 feet ‹confirm› to clear the tail. Bigger twins, turboprops, and light jets push you to 60 to 80-plus feet of width ‹confirm› and taller doors. The driver is not floor area; it is the door opening, because the plane has to fit through the front before it ever fills the room.
This page sits under the metal building uses pillar and answers one question: how big to size a steel hangar for the aircraft you fly. The sizes below are starting ranges, not engineering. Confirm your exact wingspan, length, and tail height against the plane’s spec sheet, then add clearance on every side.
The real driver
Door width and height set the size, not square footage
Size the door first, then the building follows. A plane parks nose-in, so the door opening has to clear the full wingspan with room to spare, and the door height has to clear the tail. That is why a hangar wants a wide clear-span frame with no interior posts in the doorway: a center column in the opening makes the width useless.
Add 8 to 10 feet of total clearance to your wingspan ‹confirm› so the door is wider than the plane, not equal to it. A Cessna 172 spans about 36 feet ‹confirm›, so a 40-foot door is tight and a 44 to 50-foot door is comfortable. For tail clearance, measure the plane’s height to the top of the vertical stabilizer, then give yourself a few feet of headroom above that ‹confirm›. A 12-foot door clears most single-engine tails; a 14 to 16-foot door covers taller twins and turboprops ‹confirm›.
Bifold and hydraulic doors
Hangar doors are wide and tall, so they use bifold or hydraulic one-piece designs, not roll-up garage doors. The door style affects the frame height you order, because the door has to stack or swing without eating into your tail clearance. Confirm the door type with your supplier before you lock the eave height.
By aircraft
Common hangar sizes by aircraft type
Match the building to the plane, not to a round number. The table below gives rough starting footprints and door widths by aircraft class. Treat every figure as illustrative and confirm it against your specific tail number, since two planes in the same class can differ by several feet.
| Aircraft type | Rough footprint ‹confirm› | Min door width ‹confirm› |
|---|---|---|
| Single-engine (Cessna 172, Piper) | 40×40 to 50×50 ft | 40 to 50 ft |
| High-performance single / light twin | 50×50 to 60×60 ft | 50 to 60 ft |
| Twin turboprop (King Air class) | 60×60 to 70×70 ft | 60 to 70 ft |
| Light jet (Citation class) | 70×70 to 80×80 ft | 65 to 80 ft |
| Two singles side by side | 60×50 to 80×60 ft | 60 to 80 ft |
Starting ranges, not final specs. Confirm wingspan, length, and tail height for your exact aircraft.
Depth matters as much as width. The building has to be deep enough to swallow the plane’s full length plus room to walk around the tail and open the cowling, so a hangar is often close to square or a little deeper than it is wide. If you want a workbench, tug, or fuel cart inside, add another 10 to 15 feet of depth ‹confirm›. The airplane hangar kits guide walks through these layouts in detail.
Span and loads
Clear span and wind load are non-negotiable
A hangar lives or dies on its clear span and its load rating. The whole point is an open box with no posts in the way, so the frame has to carry the roof across the full width on its own. Red iron clear-span framing does this; a multi-span building with interior columns does not belong in a hangar where you taxi a plane through the door.
Wind load is the other half. Hangars sit on open airfields with nothing to break the wind, and a tall, wide door is a large surface for it to push on, so the building has to be stamped for your local wind speed and any snow load ‹confirm›. Order the engineering for the site, not for a generic rating. For how span widths and cost scale together, the metal building sizes pillar lays out the standard widths and what each one buys.
One more clearance check: eave height. The eave has to clear the open door plus the tail, so a hangar usually runs a taller eave than a same-width garage. Confirm the door manufacturer’s required eave height before you finalize the frame, because a door that will not open to full height defeats the size you paid for.
