12x24 Metal Carport Kits: Prices, Specs & What Fits
A 12x24 carport is the single-car size for people who drive a pickup. It covers 288 square feet, keeps the standard 12-foot width for door room on both sides, and adds 4 feet of length over a 12x20 so a long crew-cab truck fits under the roof bumper to bumper. This page covers what a 12x24 costs installed, what fits, and how it compares with the 12x20 and 12x25 on builders' price sheets.

How Big Is A 12x24 Carport?
A 12x24 gives you 12 feet of clear span side to side and 24 feet front to back. As with other metal carports, the roof usually runs a foot longer than the frame, so a 24-foot frame sits under a 25-foot roof. Many builders' standard lengths step from 21 to 26 feet in 5-foot jumps, so you will often see this size quoted as a custom 12x24 or as the standard 12x25 or 12x26.
- Frame footprint: 12' x 24' (288 sq ft)
- Standard leg height: 6' to 7', with taller legs in 1-foot steps from most builders
- Framing: 14-gauge steel tubing standard, 12-gauge as an upgrade
- Roof panels: 29-gauge standard
What Fits Under A 12x24 Carport?
The 12-foot width leaves about 2.5 to 3 feet on each side of a car, SUV or half-ton pickup, enough to open doors fully. The extra length is what sets a 12x24 apart. A crew-cab pickup with a 6.5-foot bed is just over 20 feet long, which leaves its bumper at the edge of a 12x20's roof. Under a 12x24, the whole truck is covered with room to walk around the front or park a mower or a stack of storage bins at the back.
| Vehicle Or Use | Fits In A 12x24? | Notes |
|---|---|---|
| Sedan, SUV or minivan | Yes | Room to walk around the front |
| Crew-cab pickup, 6.5' bed | Yes | Fully covered, bumper to bumper |
| Crew-cab pickup, 8' bed | Close | Around 21 to 22 ft long; still under the roof |
| Car plus mower or storage | Yes | About 6 to 8 ft of spare length with most cars |
| Boat on a trailer | Usually | Measure tongue to motor; boats around 18 ft often fit |
| Two cars | No | Two cars need about 20 ft of width |
How Much Does A 12x24 Metal Carport Cost?
In our September 2026 price check, an open 12' x 24' vertical-roof carport with 7-foot legs was listed at $2,727 installed. A step up to the standard 12x25 length was advertised from $2,095 installed with a vertical roof and 6-foot legs at another installer, so compare quotes on both lengths. A 12x25 may come in lower simply because it is a stock size.
What moves the price:
- Length: Each extra 5-foot section adds another roof bow, legs and sheeting.
- Roof style: Regular roofs cost least, then boxed-eave, then vertical. A long single carport sheds snow and rain best with a vertical roof.
- Leg height: Go taller for lifted trucks, roof racks or a camper shell.
- Sides and ends: A side panel on the weather side is a low-cost upgrade; a full enclosure turns the 12x24 into a one-car garage.
- Certification and site: Engineered units for your county's wind and snow loads, your delivery zone, and site grade all change the final price.
12x24 Vs. 12x20 Vs. 12x25
| Size | Covered Area | Best For |
|---|---|---|
| 12x20 (12x21) | 240 sq ft | Cars, SUVs and standard-bed pickups |
| 12x24 | 288 sq ft | Long crew-cab pickups, or a car plus storage |
| 12x25 (12x26) | 300 sq ft | The same use as 12x24, as a stock length many builders price lower |
If your truck fits under a 12x20, the shorter size saves steel and money. If it overhangs, a 12x24 or 12x25 is the fix, and the extra roof keeps rain off the tailgate.
12x24 Carport With Sides
Enclosing one or both sides, closing the back gable, or fully enclosing the building with a roll-up door are all common on a 12x24. The extra length makes a fully enclosed 12x24 a practical one-car garage with a small workbench area. If you plan to enclose it later, tell your builder when you order so the frame is braced and certified for walls.
Concrete Slab And Anchors
Pour the slab to the frame, not the roof. A 12x24 frame under a 25-foot roof sits on a 12' x 24' pad. Builders use concrete anchors on slabs, rebar or mobile home-style ground anchors on dirt or gravel, and asphalt anchors on paved driveways.
Do You Need A Permit For A 12x24 Carport?
Probably. At 288 square feet, a 12x24 is larger than the 120- or 200-square-foot small-structure exemptions many local codes use, and some jurisdictions require a permit for any carport. Check with your local building department before you order.
Compare Other Carport Sizes
For cars and standard-bed trucks, the 12x20 carport is the standard single-car size. For two vehicles, see the 20x20 carport, or browse every size in the carport sizes guide and all single car carports.
