For many homes, the garage is the main point of entry. And when it’s time to replace the garage door, you need to ensure that it is the right size. But with a wide range of standard garage door sizes available, choosing the right size door for your home can seem like a confusing task.

Standard Garage Door Sizes

There are a number of garage door sizes which are considered standard. For instance, 1-car garage doors are in standard sizes of 8×7 ft, 9×7 ft, 10x7ft, 8×8 ft, 9×8 ft, and 10×8 ft. For 2-car garage doors, standard sizes are available from 12xft, 14×7 ft, 16×7 feet, 18×7 ft, 14×8 ft, 16×8 ft, to 18X8 ft. However, garage doors can be up to 10 or 12 ft in height if your garage was designed to accommodate RVs.

Since a single door for a 3-car garage are often too heavy to operate, 3-car garages are mostly constructed with two garage door frames: one single door and one double door. The single door is usually 8-10 feet wide and 7-8 feet high. And the double door will normally have a width between 16-18 ft and 7-8 ft high.

How to Choose the Right Garage Door Size

Follow these steps to correctly measure for your new garage door:

  1. First, measure the width of your garage door opening in feet and inches. It may be easier to lay the tape measure on the ground and carefully measure straight across from one end to the other.

  3. Now, measure the headroom. To do this, measure the distance between the top of the door opening & the ceiling in feet & inches. This will make sure there’s enough space for the opener motor & track.
  4. The next step is to account for the side room, the rails that will be on either side of the door. Measure the width from the opening to the wall on both sides for the rails.
  5. Finally, you need to measure the backroom distance. This is the distance from the door opening to the back wall. This will ensure there is enough clearance for the door to roll up and across the ceiling.
  6. For best results, consult with your local Safe-Way Garage Door dealer. Our garage door professionals will provide accurate measurements for your new garage door.
