Please use the drawing and instructions below to measure your garage door. Call us with the dimensions of your opening and headroom to give you a quote on the type of door you want.

Step #1 Measure door clear opening width and height in feet and inches. This determines the size of door needed. The finished opening should be the same size as the door.

Step #2 Measure for side room:  3-3/4" is required on each side for installation of the vertical track for standard extension springs and standard torsion springs.

Step #3 Measure area labeled “headroom” – distance between the top of the finished door opening (“jamb header”) and the ceiling (or floor joist). 10" is required for the standard extension spring and 12" is required for standard torsion spring. If you have restricted headroom, special hardware is available. Additional headroom is required for installation of an automatic garage door opener. NOTE: If door height extends above the opening, the headroom measurement should be adjusted proportionately.

Step #4 Measure area labeled “backroom” – distance is measured from the garage door opening toward the back wall of the garage. Door height plus 18" is required for the horizontal rails. Additional back room may be required for installation of an automatic garage door opener.
