Garage door sizes for a 3-car garage
The listed size is the nominal door size. Tracks, weather seals and trim usually make the clear opening slightly smaller, so measure the narrowest point. See garage door width and garage door height for vehicle-by-vehicle clearances.
Which vehicles fit a 3-car garage?
Each cell shows the combined front-and-rear space left, then the space on each side of the body when the width is split into 3 equal bays. Mirrors and door swing are not included. In the 30 × 20 ft size, 4 of our 20 vehicles would have less than 24 in of combined front-and-rear room.

Planning notes
- Each bay gets roughly a third of the width—about 10 ft in a 30-ft garage and 12 ft in a 36-ft garage. The chart below uses that per-bay width.
- A 9-ft single door is usually the narrowest point for the third bay, so check the vehicle’s mirror width against it.
- If one bay will hold a long pickup, make sure that bay has the full depth; stairs or storage at the back often sit in exactly that spot.
