How to measure for a glass garage door
Five measurements in feet and inches: width, height, headroom, side room and back room. Measure each opening, write the numbers down and send them with a few photos.
Width
Measure the finished opening at its widest point, side to side. Garage doors are sized to the opening, so this is your door width.
Height
Measure from the floor to the top of the opening at its highest point. This is your door height. It also sets the number of glass sections: one per 2 ft of height, rounded up.
Headroom
Measure from the top of the opening up to the ceiling, or to anything lower that hangs from it: a beam, a duct, a pipe or a light. The springs and the curve of the track sit in this space.
Side room
Measure from each side of the opening to the nearest wall or obstruction. The vertical tracks mount on both sides, and the opener mounts on the wall at the top of one side.
Back room
Measure from the opening to the back wall of the garage, along the ceiling. The open door lies along the ceiling, so this has to be longer than the door is tall.
Tips for accurate numbers
- Measure every opening, even ones that look the same.
- Measure the opening, not the old door.
- Look up as well as across. Lights, ducts, beams and storage racks near the ceiling can be in the way of the track.
- Take every number in feet and inches.
- Building new? Send us the drawings. Builders get the opening size, headroom and side room for each door in writing, before framing.
What to send with your quote request
