If youíre replacing your current garage door or building your dream home from the ground up, youíll need to have accurate measurements of the space in which youíll be installing the new doors. Before you choose what materials and style youíd prefer, knowing the amount of space you have to work with will help you make the right design decisions.
Standard Garage Door Sizes The most common garage door widths are 8í, 9í, 16í, and 18í. The most common heights are 7í and 8í. While most residential garage doors will fall into one of these categories, custom size garage doors are available. Therefore, you should take accurate measurements of your garage so that the perfect sizing can be ordered or fabricated for your home. Itís great if you have existing garage doors; simply take the measurements of your current doors in addition to the headroom and depth of your garage. For new doors, follow this guide for measuring the space.
Start with the Width Take the measurement of the width of your garage opening. This is from inside jamb to inside jamb.
Move Onto the Height Take the measurement of the height of your garage opening. This is from the floor to the bottom on the header.
- Use feet and inches for the clearest and simplest account of the size.
- Use a 25í tape measure to make sure that you get an accurate measurement without having to stop along the way, make marks, and continue.
Check the Headroom and Sides The headroom of your garage is the area between the top of the opening and the ceiling. Itís important to get this measurement because it will be necessary to determine the proper track configuration and spring system. Depending on available space, high lift track might be an option to allow for car lifts. If there is not a lot of space, low headroom track might be required. All of these factors influence the type of spring system used, whether it be standard extension spring or a standard torsion spring. The side room is the space along the width of your garage between the opening and the walls. This is important to assure room for the track, as well as a side mount opener if you choose this style.
- Measure from the floor up to header in three spots; left, center, right.
- Take note of any irregularities, which would indicate a slope in the floor.
Measure the Depth/Backroom Taking the measurement of the depth or backroom of your garage may require the most coordination. Itís the distance from the opening to the furthest point at the rear of your garage.
- Take note of any obstructions, like a light fixture.
- On each side of the doors or opening, measure the width from the opening to the walls.
- Itís measured along the ceiling.
- Itís important for installing the horizontal track of the door.
- Itís important to assure enough space for a traditional garage door opener.
- The opener will take up more length into your garage than the tracks.
