A 40×60 metal building kit encloses 2,400 square feet, a footprint 40 feet wide and 60 feet deep. That is a six-car garage, a full commercial shop, or a clear-span barn with no posts breaking up the floor. Forty feet of width clears two deep work bays side by side, and the 60-foot depth turns the box into a building that runs a business, stores a fleet, or houses livestock and equipment under one roof.
This guide sits under the metal building sizes pillar, and it covers one footprint in depth: what fits inside a 40×60, the uses it suits, the frame and options you will see on a quote, the clear heights you can order, and an illustrative 2026 price range. To see this size against every other footprint side by side, the metal building size chart puts it in context.
2,400 square feet
What a 40×60 metal building kit covers
Forty feet wide by sixty feet deep gives you 2,400 square feet of enclosed floor. The width is the headline: 40 feet parks six vehicles across in two rows, or two over-deep bays for trucks and trailers, and a red iron frame holds that span open with no interior post. The 60-foot depth is what pushes this size past a large garage into commercial territory, with room for a fleet, a production floor, or stalls and a tack room along one side.
Think of it as the size where a shop becomes a workplace. A 40×60 swallows a lift bay, a parts room, a small office, and a wash bay and still leaves a clear lane down the middle. That reach is why the footprint suits contractors running a crew and small manufacturers who need floor space and a tall door. If 2,400 square feet is more than you need, the 40×40 keeps the same width in a tighter box.
What fits
What fits inside a 40×60 building
Six vehicles, a full RV plus a shop, or a working fleet with room to maneuver. The table below shows how a 40×60 handles the loads people most often put in this size, and where the footprint still sets the limit.
| What you want to store | How a 40×60 handles it |
|---|---|
| Six cars in two rows | Parks six across the width with aisle room, or four with a wide work area |
| RV plus a full shop | A Class A coach down one bay, a bench, lift, and parts room across the rest |
| Work fleet and trailers | Several trucks and trailers staged in lanes with a turnaround inside |
| Boats and toys | Multiple boats on trailers plus daily drivers and gear off the weather |
| Tractor and implements | A tractor, a combine head, and attachments with a workbench under one roof |
| Horses and hay | A row of stalls along one side, a tack room, and a center aisle to work in |
What clears and what does not. A 40×60 is a fleet-and-shop building, not a personal garage.
Mind the door, not just the floor
A tall RV, a dump truck, or a piece of farm equipment can fit the floor plan and still hit the door header. The roll-up opening sets your real clearance, so order the door height around the tallest thing you park, not the average. The how to choose a size guide walks through measuring before you buy.
Common uses
Common uses for a 40×60 footprint
The 2,400-square-foot footprint is where a building stops being storage and starts being infrastructure. These are the jobs it does best:
- Commercial or trade shop. Welding, fabrication, auto and diesel repair, or a contractor base with bays, a parts counter, and an office partitioned in one corner.
- Fleet and equipment storage. Work trucks, trailers, and machines staged inside and out of the weather. For layout ideas across uses, see what people build.
- RV and toy barn. Several motorhomes, boats, or off-road rigs under one tall roof with room to service them.
- Agricultural barn. Hay, implements, and a row of horse stalls with a center aisle and a tack room.
- Light manufacturing or warehouse. A production floor, racking, and a loading door, sized for a small operation that has outgrown a rented unit.
Compare it against the longer 40×80 and the wider 50×60 before you commit, since a few feet of width or depth changes what the building can hold and what it costs to heat.
Frame and options
The frame, doors, and clear height
At a 40-foot width, kits this size use a bolt-up red iron frame, because that span asks for the load rating and the clear floor a structural frame gives you. The primary frame is structural I-beam, not light tube, and that is what holds 40 feet open with no center post. The lighter secondary members are sold by wall thickness in gauge, where a lower number means thicker steel.
Clear height is where buyers most often under-order. The eave height, the wall height at the side, sets how tall a door you can hang and how much headroom you keep inside. A 40×60 is commonly offered with side walls from about 12 to 20 feet ‹confirm›. Fourteen feet suits a shop with a lift; go to 16 feet or more if you want a tall RV door, a stacked rack, or a dump bed raised inside. A taller eave costs more steel, so order the height your tallest job needs and not a foot more.
On the options list you choose a roof style, the doors, and any openings. A pair of large roll-up doors plus a walk-in door covers most commercial builds, with a third opening for a drive-through if you need it. The roof comes as standard, A-frame, or vertical-rib, with the vertical roof shedding water and snow better for a small premium. Order the certified load rating for your county so the kit is stamped for local snow and wind.
Order the size you will grow into, not the one that just fits today. A few feet of eave height or a second drive-through door costs far less now than a rebuild later.
Price
What a 40×60 metal building kit costs in 2026
As a 2026 illustration, a 40×60 steel shell kit runs roughly $30,000 to $65,000 ‹confirm› for the bare building. The spread is wide because eave height, roof style, door count, and the certified load rating each move the number. A basic enclosed shell with a low eave sits near the bottom; a fully certified red iron shop with a tall eave, several roll-up doors, and a vertical roof sits near the top ‹confirm›.
That figure is the kit alone. Budget separately for a concrete slab, delivery, and any insulation or interior finish, which can add tens of thousands of dollars ‹confirm› on top of the shell at this footprint. For the full breakdown of what drives the total, see the metal building kit prices pillar.
Treat any single number with care: prices move with the steel market, your location, and the season. Get a written quote stamped for your address, confirm the frame type and the load rating, and check it against current ranges in the size chart before you sign.
FAQ
40×60 metal building kits: common questions
How many square feet is a 40×60 building?
A 40×60 building is 2,400 square feet, found by multiplying 40 feet of width by 60 feet of depth. That is the footprint of a six-car garage, a full commercial shop, or a clear-span barn with no interior posts to work around.
How many cars fit in a 40×60 garage?
Six vehicles fit in two rows across the 40-foot width and 60-foot depth, or four with a wide work area left over. The clear-span frame keeps the floor open with no center post, so you can park two rows deep or run equipment across the bays.
How much does a 40×60 metal building cost?
As a 2026 illustration, the bare shell kit runs roughly $30,000 to $65,000 ‹confirm›, depending on eave height, doors, roof style, and the certified load rating. A slab, delivery, and insulation are extra. Always get a written quote stamped for your location before you compare prices.
How tall can a 40×60 building be?
Side wall, or eave, heights of about 12 to 20 feet ‹confirm› are common at this size. Fourteen feet suits a shop with a lift; order 16 feet or taller if you want a tall RV door, stacked racking, or a dump bed raised inside. The eave height sets how tall a door you can hang.
Will an RV fit in a 40×60 building?
Yes, with room to spare on the floor, but the roof height is the real limit. A tall Class A coach needs a 16-foot or taller eave and door, so confirm the clear door opening, not just the floor length, before you order.
Does a 40×60 kit use tube steel or red iron?
Red iron. At a 40-foot width a bolt-up structural frame gives you the clear span with no center post and the load rating a building this size needs. Light-gauge tube is suited to narrow carports and small garages, not a 40-foot span carrying a commercial roof.
