Garage door measurements involve more than just taking the width and height of the rough opening. The springs, track, hardware, and garage door opener must fit properly. Therefore other measurements must be taken as well. New garage door installations must also account for important clearances, including headroom, side room, and backroom.

Time and money will be wasted if you don’t plan for adequate headroom, side room, and backroom. Taking accurate measurements of a roll up door parts supplier, both before and after installation, is essential. By following the instructions you can ensure that you get the right measurement for your garage door opening the first time.

Sizes of Roll-Up Door

Doors up to 30’4″ (9.2m) wide and 28’4″ (8.6m) high are considered conventional, and bespoke doors can be made to cover an area of up to 1,500 square feet (1.39 sq.m). When choosing a roll-up door, it’s important to consider the height, width, and height of the area behind it.

The primary factors in determining these dimensions are the rough opening size, the surface area of the mounting brackets, and the clearance dimensions. Door Systems is a one-stop shop for all your project requirements; we handle the size and measuring, so you don’t have to.

Other Roll-Up Door Factors to Consider

● Security

Whatever is behind that door—confidential paperwork, pricey equipment, or valuable stock—is likely essential to the smooth running of the firm, and any disruption to its access would cause a major inconvenience.

● Speed and Insulation

Using poorly insulated roll-up doors and otherwise doors that open and shut slowly is not an option when developing or renovating a building with a refrigerated room or area that has to maintain a specified temperature.

● Wind Resistance & Durability

How long your roll-up doors, of whatever size, will endure should be the last thing on your mind. We’ll help you pick durable doors that will last a long time. Nothing lasts forever, and regular motor use will eventually wear down the moving parts. Investing in doors with lifetime warranties from the manufacturer (rated for at least 50,000 cycles) is a good idea.


Measuring a garage door requires more than simply the general dimensions of the entrance. Because of the need for a snug fit for the garage door’s forces, track, hardware, and opener, additional measurements will need to be obtained. Clearances, such as height, width, and depth, must be taken into consideration when installing a new garage door. Lack of consideration for proper headroom, side room, as well as backroom will result in lost time and resources.
