Garage Door Installation Process

How-To-Measure for your New Residential Garage Door

Use the drawing and instructions below to measure your existing garage door. Take these measurements to your local installing dealer or retailer to purchase the Clopay® garage door that is right for you.

Step #1

Measure the width and height (1 and 2) of your door opening in feet and inches to determine the garage door size you need. The rough opening should be the same size as the door.

Step #2

Measure area labeled sideroom left and right (3 and 4) - a minimum 3-3/4" is required on each side for installation of the vertical track for a standard extension spring, standard torsion spring and the EZ-SET® Torsion Spring System; 5-1/2" for the EZ-SET® Extension Spring System.

Step #3

Measure area labeled headroom (5), which is the distance between the top of the door opening (jamb header) and the ceiling (or floor joist). 10" is required for the standard extension spring or EZ-SET® Extension Spring System while 12" is required for a standard torsion spring and EZ-SET® Torsion Spring System. If you have restricted headroom, special hardware is available. Additional headroom is required for installation of an automatic garage door opener. NOTE: If garage door height extends above the opening, the headroom measurement should be adjusted proportionately.

Step #4

Measure area labeled backroom (6) – distance is measured from the garage door opening toward the back wall of the garage. Door height plus 18" is required. Additional back room may be required for automatic garage door opener installation.

While it is possible to install your Clopay garage door on your own, you can get additional peace of mind by getting professional installation by a Clopay Dealer. Clopay also offers a 1-year installation warranty on replacement garage doors installed by a Master Authorized or Authorized Clopay Dealer.
