Standard Garage Door Sizes: Dimensions and Measurements

When selecting a new garage door for your house, selecting the appropriate size is essential. A properly sized door ensures proper installation and efficient operation, enhances your home’s safety and security and adds to its visual appeal.

To assist you in choosing the most suitable garage door for your house, AGS – Home Services, LLC, a trusted garage door installation and repair service provider, has summarized this helpful guide to standard garage door sizes.

Standard Garage Door Sizes

Single-car garages’ most common garage door widths are 8, 9, and 10 feet. However, when it comes to two-car garages, width variations increase. A standard two-car garage may have a garage door that is 16 or 18 feet wide or even more if required. For homeowners with larger garages that accommodate more than two cars, wider doors are necessary.

The height of a standard residential garage door is usually either 7 or 8 feet. However, if you have a taller vehicle or your garage has ceilings taller than 8 feet, it’s important to consider a taller garage door. It will ensure that your car fits comfortably inside, and you won’t encounter any issues when opening the door.

Measuring Garage Door Opening

Measuring the garage door opening is crucial in selecting your home’s right garage door size. Here’s how to measure your garage door opening step by step:

Step 1: Measure the Width

Start by measuring the garage door opening from side to side. Ensure that you take your measurements at the widest point without including any irregularities in the width or shape of the opening. Measure the distance between the two jambs or opening headers.

Step 2: Measure the Height

The height of the entrance should be measured from the ground up. The door opening height should then be measured. While taking this measurement, don’t include the garage door’s bottom edge.

Step 3: Measure the Depth

Lastly, measure the depth or thickness of the opening. Before choosing a garage door, measure its depth to ensure it will fit your garage’s opening and suit your opener.

It’s important always to take accurate measurements to ensure the garage door functions properly and provides smooth operation. Once you have determined the garage door opening measurements, various standard garage door sizes are available based on your preference, budget, and style.
