How to Measure for a New Garage Door?
- Measure Width & Height - The width and height of the garage door opening is the same size as your new garage door.
- Measure Sideroom - This is the width of the areas on the left and right of the garage door opening. Opening must be at least 3-3/4” on each side.
- Measure Headroom - This is the distance between the top of the door and the ceiling (or 1st obstruction). Distance required for most doors with an opener is 15”.
- Measure Backroom - This is the distance from the garage door to the rear of the garage (or 1st obstruction). This must be at least the door height plus 18”; or door height plus 50” if an opener is installed.
