Tools Required for Measuring a Garage Door

To begin, you will need a tape measure, a step ladder, a notepad, and a pen. These tools will help you measure the dimensions of the garage door accurately.

Step-by-Step Garage Door Measuring Guide

Measuring the Width

Start by measuring the width of the garage door opening at the widest point. This is typically done from the middle of the left side of the opening to the right. Measure across the bottom of the door opening first, and then measure at the middle and top of the opening to ensure consistency. Record the smallest measurement, as this will be the most accurate width for the garage door.

Measuring the Height

Next, measure the height of the door from the highest point of the floor at the bottom of the opening to the top of the opening. Similar to measuring the width, measure the height at the left, middle, and right side of the opening. Use the smallest of these measurements as the height for your garage door.

Measuring the Headroom

The headroom is the space between the top of the door opening and the ceiling. Measure this space to double check there is enough room for the garage door to operate correctly, especially if you plan to install an automatic garage door opener. The standard required headroom for most doors is about 12 inches, but some systems may require more.

Measuring the Sideroom

Sideroom measurements are essential, especially for installing the garage door tracks. Measure the width of the areas beside the openings on both sides. Most garage doors require at least 3.75 inches on each side to accommodate the installation of the vertical track.

Measuring the Backroom

The backroom is the distance from the garage door opening to the back wall of the garage. This measurement is critical for the garage door to open fully. The required backroom is typically the door height plus an additional 18 inches.

Common Garage Door Sizes

Standard Garage Door Sizes

Most garage doors come in standard sizes that fit most homes. For single garage doors, common sizes are 8 x 7 feet, 9 x 7 feet, and 10 x 7 feet. For double garage doors, commonly used for two-car garages, the standard sizes are 16 x 7 feet, 14 x 7 feet, and even 12 x 7 feet.

Standard Two Car and Three Car Garage Sizes

Standard garage door sizes for a two-car garage typically start at 16 feet wide by 7 feet high. Three-car garage doors might be significantly wider, depending on the layout and space available, often needing a custom size or multiple single doors.

Considerations for New Garage Door Installation

When planning for a new garage door or replacement, consider the architectural style of your home, the material of the door, and whether you need additional features like windows, insulation, or an automatic garage door opener. Accurate measurements will help ensure that the door and any accessories fit well and operate smoothly, adding convenience and security to your home.
