Read further to find out how to choose the best size for your future garage door. This article will also help you to measure garage doors properly and avoid common mistakes people make.

How To Measure Your Garage Door

How wide is a garage door? How tall is it? These are the most important measurements to ensure that a new door is sized correctly. What are all the measurements you’re going to need?

To get the perfect garage door, you need to make the proper measurements. What exactly do you need to measure?

1. The width and height of existing garage door opening.

These are the most important measurements. The room for drive through depends on the width and height of the opening, so pay attention to it. This also determines the size of the door you’ll need. Keep an eye on possible defects, such as an uneven opening or un-level floor.

2. Internal headroom.

This is the space between the ceiling and the top of the door opening. It’s important for fitting sectional garage door tracks or placing a curtain roll for a roller shutter garage door.

3. The width of the side room on both sides of the door.

You need this measurement to fit the door frame and the door mechanism properly. This measure requires up to 3.75” on each side. If you’re dealing with a double garage door, make a 10” wide center post.

4. The depth of the garage.

This is a necessary measurement for an up and over, sectional or side hinged door that opens inside. You need to have enough room for the door to open properly.

5. Consider all the obstructions when measuring.

What can be an obstruction? Pipes, lighting and nearly anything that interferes with the door track.
