The Ultimate Guide to Garage Door Sizes

It’s virtually impossible to imagine the life of a modern man without a car. When you own a car (or are just thinking of getting one), you need to take care of the place you’re going to keep it in.

Sure thing, we talk about garages, but what about the door? You have to think not only about the inner space, but about the garage door size as well.

Americans use the garage more than any other entry to the house, including the front door.

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

5

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.

How To Measure Up and Over Doors

Measurements for up and over garage doors are quite simple. In most cases, all you need to know is the height and width of the garage opening. Although, there’s one thing to keep in mind.

Measurements do differ depending on how exactly you want to install the door. An up and over garage door has an inner frame and operating gear. It will take up extra space, so the actual opening will be smaller. Frame legs are usually around 60 mm wide.
