Garage Door Sizes

What size garage door do you need for your home? Are custom garage door sizes? How big is a two-car garage? 

If you’re installing a new garage door in Maryland, you probably have questions about sizing a garage door. Some of the most important considerations when buying the right-sized garage door are:

  • The size of your home
  • Whether the garage will be attached to the home or not
  • The number and types of cars that will be parked in the garage

Fortunately, your professional garage door installers at Accurate Insulation team can  handle all the measurements and calculations. But first, let’s dive into the factors that go into how to size a garage door.

What Size Garage Door Do I Need?

The average garage door size can vary, but a typical single-car garage door is 8′ x 7′ or 9′ by 7′. A two-car garage door size is typically 16′ by 7′.

We install a variety of garage doors sizes in Maryland. The most common widths we install are:

  • 8 feet
  • 9 feet
  • 10 feet
  • 12 feet
  • 14 feet
  • 15 feet
  • 15 feet, 6 inches
  • 16 feet
  • 18 feet

Buying Custom Garage Door Sizes

Standard Clopay garage door heights are from 6 feet to 8 feet in 3-inch increments (except for 7 feet, 3 inches). Some garage doors can be custom ordered in 2-inch increments—contact us about custom width garage doors and model availability.

How to Measure for a Garage Door

While DIY garage door installation is an option for some homeowners, most prefer the peace of mind of professional installation. If you’re the DIY type — or if you just want to know what size garage door you need — here’s how to measure for a new garage door:

  1. Measure the width and height of your garage door opening. Garage doors are sized in feet and inches.
  2. Measure the space to the left and right of the garage door opening. This area should be a minimum of 3-3/4″ to allow the tracks to be installed.
  3. Measure the distance between the top of the door opening (jamb header) and the ceiling to determine the headroom required. A standard extension spring requires 10″ of headroom. If you’re installing an automatic garage door opener, you’ll need additional headroom.
  4. Measure the distance from the garage door opening to the back wall of the garage. This distance must be at least the height of the door plus 18″. Additional room may be necessary if you’re installing a garage door opener.
