Instructions to Measure Your Garage Door

Follow these instructions to measure your existing garage door. Send the measurements and photos over to us and we’ll quote the Clopay garage door that is right for you. Follow the steps below and refer to the diagram on the right to help you. Please take all measurements in feet and inches.

1. Height and Width

The rough opening is the height and width of the framed opening not including stop molding.

  • Rough opening should equal the same size as the door.


2. Left and Right-Side Room

The side room is the distance required on each side of the door to allow for attachment of the vertical track assembly.

  • Minimum 3-3/4" is required on each side of the door for a standard extension spring, standard torsion spring, or EZ-SET® Torsion Spring system.
  • Minimum 4-1/2" is required for a standard torsion spring or EZ-SET® Torsion Spring system above the opening for torsion spring attachment.


3. Headroom

Headroom is the space needed above the door for the door, overhead tracks, and springs. There should be no obstructions in the garage within this space.

Measurements from the top of the door opening to the ceiling (or floor joist) should be:

  • Minimum 10" for extension springs
  • Minimum 12" for torsion springs

Note: If there is restricted headroom, low headroom options are available.


4. Backroom

The backroom is the distance required from the garage door opening toward the back wall of the garage.

  • Minimum measurements should equal the height of the door plus 18".

Please take all measurements in feet and inches.
