Start with what goes inside
Measure your vehicles, then add room to open doors and walk around. A typical full-size pickup is about 18 to 20 ft long and 6.5 to 7 ft wide without mirrors.
| Cars | Tight | Comfortable | With storage or bench |
|---|---|---|---|
| 1 | 12 x 20 | 14 x 25 or 20 x 20 | 20 x 25 |
| 2 | 20 x 20 | 24 x 25 | 24 x 30 |
| 3 | 30 x 25 | 30 x 30 | 30 x 40 |
Doors
- One car: an 8 or 9 ft wide roll-up door.
- Two cars: two 8 to 10 ft doors, or one 16 ft door (a frame-out).
- Height: roll-up door height is usually about 1 ft less than the leg height. An 8 ft door needs about 9 ft legs.
- Walk-in door: add one so you're not opening the roll-up every time.
Height
- 9 ft legs: cars and most SUVs.
- 10 to 12 ft legs: lifted trucks, vans, storage racks.
- 14 ft and up: car lifts, RVs and tall equipment. Check the truss clearance, not just the leg height.

Width costs the most
Adding length adds one more frame section. Adding width changes the trusses, and cost jumps at 30 ft and again past 32 ft. If you're between two widths, price both.
