How to Size a Metal Garage

Measure what goes inside, add room to move, then pick the width, length and height.

The most common regret with a metal garage is buying one that's too small. Here's a quick way to get the size right the first time.

Start with what goes inside

List every vehicle, trailer and piece of equipment you plan to store. A typical pickup needs about 10 ft by 20 ft. Add 3–4 ft between vehicles so you can open doors.

Width

  • One car: 12–14 ft
  • Two cars: 20–24 ft
  • Three cars or a workshop: 26–30 ft

Length

Add 4–6 ft to your longest vehicle for walking room and a workbench. Lengths usually come in 5 ft steps.

Height

For cars and most trucks, 8–10 ft legs are enough. Plan on 12 ft or more for a lift, an RV or a tall door.

Doors

Roll-up doors usually run from 8×7 ft for a car to 10×10 ft or larger for trucks and equipment. Add a walk-in door so you don't have to open the big door every time.
