Standard Garage Door Size report

A green car parked in front of the garageA new garage door can increase the curb appeal of your home. One of the first steps to garage door installation is determining the correct size of the new garage door you need. The dimensions of a standard single garage door are 10 x 7 feet, 9 x 7 feet, and 8 x 7 feet. These sizes are ideal for typical homes that need to provide accommodation for a truck, SUV, or car. Families with large vehicles or multiple vehicles should consider purchasing a larger garage door.

Motorhomes, short tails, and large trucks are not the kind of vehicles that can easily pass through a single garage door. If you need to store many items other than vehicles, a larger door may be the right choice for your home or business. If you are building a new house, make sure that the size of the garage can meet your current needs.

Garage doors usually do not have a fixed size because the size of the garage door is not only related to the size of the car but also takes into account the area of the garage and the number of cars parked in the garage. Read this guide to review the standard garage door sizes and how to measure a garage door.

Standard Garage Door Types

When building or remodeling a garage, several factors must be considered, including personal preference and needs based on the number of vehicles, practicality, and the cost of maintaining multiple doors. The garage door types you need depend on the size and layout of your garage itself.

  • Single Garage Door

This type of garage door is perfect for smaller garage spaces with room for only one vehicle, and single garage doors most commonly measure either 7 or 8 feet in height and 8, 9, or 10 feet in width. The doors are suited for a single standard-sized car, SUV, truck, or van.

  • Double Garage Door

The standard size for double garage doors is 16 or 18 feet wide and 7 to 8 feet high. Many people have two cars and need more space to shelter them both. Fortunately, the cost for two single garage doors is nearly the same as a double door.

  • RV Garage Door

Large garage doors are available for specialized needs, such as parking several vehicles or an RV. These oversized garage doors tend to be 10, 12, or 14 feet in height and width. And many people use large garages as a workshop or storage space.

  • Combination Garage Door

A garage with a combination of either multiple single doors or a single and double door is rare. These garage door designs offer more space and flexibility and require maintenance and upkeep of at least two separate openers and garage door systems.

  • Custom Garage Door

Custom garage doors can offer a door height of 10 feet or more. This higher height can accommodate large vehicles such as trucks, recreational vehicles, or vehicles with tall roof racks.

How To Measure A Garage Door

Measuring a garage door determines the size of the door and ensures that the garage can accommodate the opener and the door in both the open and closed positions. There are step-by-step instructions for measuring a garage door.

  1. Place a tape measure to determine the width and height of the door opening in inches. The size of the door will be approximately the same as it.
  2. Measure the space available on the left and right sides of the opening, called "side room." Most vertical track systems require 3.75 inches on each side, and custom systems may require even 5.5 inches.
  3. Measure the distance between the top of the opening and the ceiling, called the "headroom."
  4. Measure the distance from the garage door opening to the back wall of the garage, which is called the "backroom."

If you’re considering purchasing a new garage door, do not forget to measure your door by the above steps, which will ensure you are looking at the right options.
