Framing a Garage Door

If you are planning on installing a new garage door, there are many considerations that should be taken into account prior to installation. Please see the diagram below that may help you to make sure your opening is the right size. These instructions will help you ensure that your framing is structurally sound.

It is always recommended that a trained garage door installer install your door for you for your safety. Ask our knowledgeable sales staff about garage door frame aluminum capping. We can do that too!

Rough Stud Opening

• 1.5 inches higher in height
• 3 inches wider in width

Finish Frame

• Exact size of door, NO BIGGER
• ie. 8 × 7 door rough opening 8’3 x 7’1 ½
• Finish opening 8 × 7

Back Framing

2 × 6 flush with finished frame on its flat against inside wall, extend 12‑15 inches past opening. If you are framing for highlift, please extend the backframing even higher (as high as the tracks will go).

In Center Pad

• In center above door opening 2 × 8 or 2 × 10 from header to ceiling or at least 12". Must be flush

In Center Pad

• Need 12" for single doors, 15" for double doors. If less, please call us and let us know as you may require low headroom hardware
• If entrance to house is right beside a door, make sure the door will clear top of entrance door. If not, you will require "high lift" hardware.
