Standard Garage Door Sizes & How To Measure Yours


If you're considering garage door replacement for your home in the North Georgia area, you'll need to figure out the exact measurements of your current setup. Starting with accurate dimensions will ensure that your new door fits perfectly and performs well.

At Balanced Garage Doors, we guide you through the selection and measurement process for a seamless installation. Whether you're looking to update your home's look or replace a damaged garage door, understanding standard sizes and how to measure your garage door is the first step.

What Are Standard Door Sizes?

Garage doors come in various standard sizes for both single and double-car garages. However, not all garage doors are standard, and you may need to take special measurements if your garage door comprises panels. We recommend having a professional from Balanced Garage Doors perform the measurements to ensure precision.

Common Garage Door Heights

Standard garage door heights are generally 7 feet (84 inches) and 8 feet (96 inches). These doors are often divided into panels of varying heights:

  • 7′ garage doors are often composed of four 21″ panels.
  • 8′ garage doors often comprise two 21″ panels and three 18″ panels.

Larger garage doors require a bigger radius (the curved section of the garage door track). The structure of the panels must match the radius of the garage door track for smooth operation.

Common Garage Door Widths

Width is equally as important as height when it comes to garage doors. Standard widths for single-car garages range from 8 to 10 feet, while double-car garage doors typically measure 16 or 18 feet across.

How To Measure Your Garage Door

Measuring your garage door is straightforward but requires attention to detail to avoid common pitfalls like uneven floors or sagging headers. Start by measuring the width from one side of the opening to the other, measuring from the inside of the jam boards. For the height, measure from the floor to the bottom of the horizontal jam board at the top of the opening.

Remember, small discrepancies in floor level or header positioning can affect your measurements, so consider these factors when determining the final size.
