How do I measure my garage door?

There is no much measurement work and calculations needed from your side if you are going for the standard size garage door. You will need to measure different aspects like height, depth, and door opening size. You will need to measure the carpet area, opening height and width of the garage for making a custom-designed garage door. Go step by step to do this accurately.

Headroom

First, measure the space between the top edge of the opening and the ceiling of your garage. It is called headroom and its measurement is crucial as different garage doors need different headroom sizes.

Backroom

Next comes the backroom, which means the depth of the garage. Measure it from the front part to the end of the ceiling of the garage. If you are planning for installing a sectional garage door, this measurement is essential.

Door sides

After that, measure the sides. They are the edges on both sides of the opening of your garage door.

Door height and width

You will need to know the garage door height and width by measuring the opening from floor to the top and from one edge to the other.

How much garage space do you need?

There are several factors you need to consider while planning a new garage or rebuilding an existing garage. Specifically, the breadth and depth of the parking area and the size of the doors requires your attention.

If you have 3 to 4 people in the family and use only one car, a single door garage is enough for your needs. You will also be able to store several small tools if you smartly utilise the space. But if you have a big family and have more than one car, you should go for a double garage or an even larger one.

Additionally, you may want to store bikes and recreational tools and some other stuff for your kids. Hence a larger parking space will be a good choice while planning for building your home and a new garage.

A standard single car garage is 5.4 to 6m long and 3m wide with a 2.4m door size suitable for a small to a medium-sized car. On the other hand, a double garage may have the same depth but will need double the width and door size. That means you will need at least a 5.4 to 6m wide garage with a 4.8m door size.
