A 24×30 metal building kit encloses 720 square feet, a footprint 24 feet wide and 30 feet deep. That is a roomy two-car garage with a shop built in: park two vehicles side by side with walking room between them, and still keep a full work bay across the back. The extra four feet of width over a standard 20-foot garage is what lets you open both car doors and move around the vehicles instead of squeezing past them.
This guide sits under the metal building sizes pillar, and it covers one footprint in depth: what fits inside a 24×30, 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 how this size stacks against every other footprint, the metal building size chart lays them out side by side.
720 square feet
What a 24×30 metal building kit covers
Twenty-four feet wide by thirty feet deep gives you 720 square feet of enclosed floor. The width is the part that sets this size apart: 24 feet is a generous two-vehicle width, wide enough that two cars or trucks sit side by side with a comfortable aisle and full door swing between them. The 30-foot depth then adds a back zone for a bench, shelving, or a second machine.
Picture a two-car garage with breathing room on both axes. Two vehicles fill roughly the front 20 feet, leaving about 10 feet of clear depth along the back wall for storage or a work area. That balance of width and depth is why a 24×30 is a favorite with owners who park and work under one roof. If you want a true third bay alongside two vehicles, step up to the deeper 24×36 instead.
What fits
What fits inside a 24×30 building
Two vehicles with elbow room, or one vehicle and a genuine shop. The table below shows how a 24×30 handles the loads people park in this footprint, and where it starts to run short so you are not guessing on the wrong size.
| What you want to store | How a 24×30 handles it |
|---|---|
| Two cars side by side | Fits both with a walking aisle between and storage behind |
| One vehicle plus a shop | Truck up front, a full bench and tool wall across the back |
| Pickup or work truck | Parks with depth to spare for a trailer or gear behind it |
| RV or camper | A length up to roughly 28 feet ‹confirm›, if the door height clears the roof |
| Boat on a trailer | Fits with room to walk both sides and reach the motor |
| Tractor and implements | A compact tractor plus a mower and attachments under one roof |
What clears and what does not. A 24×30 is a wide two-lane building with workshop depth.
Mind the door, not just the floor
A tall truck or an RV can fit the floor plan and still hit the door header. The roll-up opening sets your real clearance, so size the door height around the tallest thing you park. The how to choose a size guide walks through measuring before you buy.
Common uses
Common uses for a 24×30 footprint
The 720-square-foot footprint hits a sweet spot: wide enough for two vehicles with room to work, yet still priced within reach for a homeowner. These are the jobs it does best:
- Two-car garage with a shop. Two daily drivers locked away, with a back wall set up for tools, a bench, and seasonal storage.
- Home workshop or hobby shop. Woodworking, welding, or a maker space with a vehicle bay alongside. For ideas on what fits each footprint, see what people build.
- RV, boat, or toy storage. One large rig or several smaller toys off the weather, with aisle room to load and unload.
- Small business or trade base. A contractor’s home for a work truck, materials, and a parts bench under cover.
- Barn, studio, or finished room. Insulate and line the walls and the wider span gives you a true room, not a narrow corridor.
If you want covered space more than an enclosed room, the same footprint works as an open or partly enclosed cover for less money. Weigh it against the squarer 24×24 and the narrower 20×30 before you commit, since a few feet of width or depth changes what the building can hold.
Frame and options
The frame, doors, and clear height
At a 24-foot width the frame can go two ways: light-gauge tube steel on a budget build, or bolt-up red iron when you want a clean clear span and a higher load rating. Frames are sold by wall thickness in gauge, where a lower number means thicker steel; 14-gauge tube is the lighter choice and 12-gauge is the stouter upgrade ‹confirm› for wind or snow country. A red iron frame clears the floor of interior posts, which matters once you park two wide vehicles abreast.
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 get inside. A 24×30 is commonly offered with side walls from about 8 to 16 feet ‹confirm›. Nine feet suits cars and a workbench; go to 12 feet or more if you want a lift, a tall RV, or loft storage overhead.
On the options list you pick a roof style, the doors, and any openings. Two roll-up doors plus a walk-in door and a window cover most two-car builds. The roof comes as a standard, A-frame, or vertical-rib style, with the vertical roof shedding water and snow better for a small premium. Choose 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 taller eave or a second roll-up door costs far less now than a rebuild later.
Price
What a 24×30 metal building kit costs in 2026
As a 2026 illustration, a 24×30 steel shell kit runs roughly $10,000 to $22,000 ‹confirm› for the bare building. The spread is wide because frame type, gauge, eave height, roof style, door count, and the certified load rating each move the number. A light 14-gauge open cover sits near the bottom; a fully enclosed, certified red iron garage with two roll-up doors and a tall eave 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 several thousand dollars ‹confirm› on top of the shell. For the full breakdown of what drives the total and how to read a quote line by line, 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 the figure against current ranges in the size chart before you sign.
FAQ
24×30 metal building kits: common questions
How many square feet is a 24×30 building?
A 24×30 building is 720 square feet, found by multiplying 24 feet of width by 30 feet of depth. That is the footprint of a wide two-car garage with a shop, which parks two vehicles side by side with a walking aisle and still leaves about 10 feet of depth across the back for a bench or storage.
Will two cars fit in a 24×30 garage?
Yes, with room to spare. At 24 feet wide a 24×30 parks two vehicles side by side with a comfortable aisle and full door swing between them, plus roughly 10 feet of depth left over ‹confirm› for tools and storage. The extra width over a 20-foot garage is what makes it feel open rather than tight.
How much does a 24×30 metal building cost?
As a 2026 illustration, the bare shell kit runs roughly $10,000 to $22,000 ‹confirm›, depending on frame type, gauge, 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.
How tall can a 24×30 building be?
Side wall, or eave, heights of about 8 to 16 feet ‹confirm› are common at this size. Nine feet suits cars and a bench; order 12 feet or taller if you want a lift, a tall RV, or overhead loft storage. The eave height sets how tall a door you can hang.
Is a 24×30 big enough for a workshop?
Yes, and it parks two vehicles at the same time. The 30-foot depth gives you a vehicle bay up front and a full bench across the back wall, while the 24-foot width keeps an aisle open. If you need two work zones plus two parked vehicles, look at a deeper footprint such as a 24×36.
What is the difference between a 24×30 and a 20×30?
Both are 30 feet deep, but a 24×30 is four feet wider, which adds 120 square feet and a real aisle between two parked vehicles. A 20×30 fits two cars but you sidle past them; a 24×30 lets you open both doors and walk around. The wider building costs a little more but earns it on a daily-use garage.
Does a 24×30 kit use tube steel or red iron?
Either. At a 24-foot width a budget kit can use light-gauge tube steel, while a red iron frame gives you a clear span with no center post and a higher load rating. Red iron costs more up front but keeps the full width open for two wide vehicles and heavier snow.
