When considering the purchase of a garage door, accurate measurements are crucial to ensure a proper fit and optimal functionality. This guide outlines the key measurements to take before making your selection, particularly in the context of South African measurement units.

Firstly, measure the width of the garage opening. This is done by measuring the distance between the two vertical sides of the opening. It is essential to take this measurement at three different points: the top, middle, and bottom of the opening. This will help identify any irregularities in the structure. The widest measurement should be recorded.

Next, measure the height of the garage door opening. Similar to the width, this should be measured at three different points: the left side, middle, and right side. The highest measurement should be noted, as this will determine the height of the new garage door.

Additionally, it is important to assess the headroom available above the garage door opening. Headroom is the space between the top of the door opening and the ceiling or any obstruction above it. A minimum of 400 mm of headroom is typically required for standard garage door installations, but this can vary based on the door type and mechanism.

Another critical measurement is the backroom depth, which is the distance from the garage door opening to the back wall of the garage. This measurement is particularly important for sectional garage doors, which require sufficient space to operate effectively. A minimum of 3000 mm of backroom is generally recommended.

Lastly, consider the side room available on either side of the garage door opening. This space is necessary for the installation of the door tracks and hardware. A minimum of 200 mm of side room is typically required for most garage door types.

In summary, the following measurements should be taken into account:

• Width of the garage opening (measured at three points)
• Height of the garage opening (measured at three points)
• Headroom above the opening
• Backroom depth
• Side room on either side of the opening

By taking these measurements accurately, you can ensure that your new garage door will fit properly and function effectively, enhancing both the security and aesthetic appeal of your home.
