Gather Your Tools

Gather the necessary tools and materials before you begin measuring your garage door. You’ll need a tape measure, a pencil, paper, and a ladder to access all parts of the door.

Measure the Width

The first dimension to measure is the width of your garage door opening. To do this, follow these steps:

  • Stand inside the garage with your back against the wall, facing the door opening.
  • Use your tape measure to measure the width from one side of the opening to the other in multiple places to ensure accuracy.
  • Write down the most comprehensive measurement you can obtain. This will be the width of your garage door.

Measure the Height

Next, measure the height of the garage door opening. Follow these steps:

  • Stand inside the garage, facing the entrance.
  • Measure from the floor to the top of the space, again measuring in multiple places.
  • Write down the highest measurement you obtain. This will be the height of your garage door.

Measure the Headroom

The headroom is the space above the door opening needed for the entry and its hardware to operate smoothly. Measure the headroom as follows:

  • Place your ladder directly under the garage door header.
  • Measure the distance from the top of the door opening to the ceiling or any obstructions.
  • Note the measurement, as this will help determine the type of garage door opener you can install.

Measure the Sideroom

Sideroom is the space on either side of the garage door opening. To measure it:

  • Measure from the inside of the door opening to the nearest wall on both sides.
  • Ensure you measure from the same point on both sides, typically from the vertical track.
  • Write down these measurements, which will help determine the type of track and hardware required.

Measure the Backroom

The backroom is the distance from the back of the garage to the door opening. It’s essential for the garage door to open and close smoothly. To measure it:

  • Measure from the back wall to the nearest obstruction inside the garage.
  • Note this measurement to ensure that your chosen garage door will fit properly.

Determine the Type of Garage Door

Now that you have your measurements, it’s time to decide on the type of garage door you want. You can choose from various options, such as sectional, roll-up, or swing-out doors. Your measurements will help you make the right choice.

Consult with Professionals

Consulting with professionals is always a good idea if you need clarification on any aspect of measuring your garage door. They can provide guidance and ensure you get accurate measurements for a hassle-free installation.
