Ever wonder what the standard sizes were for garage doors in Katy and Houston? If you have been looking to replace your garage door in the Katy area, chances are you are going to discover that there are two standard sizes: 8×7 which is considered a single car sized door, and 16×7 which is considered a double car sized garage door..


Don’t think your garage door is standard?

Accurate measurements are essential to ensure a seamless fit and optimal functionality. To assist you in this process, the following steps outlined by Amarr will help you on how to determine the dimensions required for your new garage door.


  1. Evaluate the opening by measuring the height and width of the opening on the inside of the door jambs.This is what the size of your door should be.
  2. Evaluate side clearance by measuring the space from the doorway to the wall. It must be at least 3 ¾”. More is better!
  3. Evaluate the headroom by measuring from the header to the ceiling – or first obstruction. You will need at minimum 15” headroom if you plan to install a garage door opener.
  4. Evaluate the clearance from the garage door opening back into the garage. Measure from the garage door back the distance of the door plus 18”. If you intend to install an opener, add 50”.



Starting From Scratch?

If you are building a home you are not limited to the standard 16×7 or 8×7 options. Doors can be made in a multitude of sizes. When making that decision here are some things to consider:

  1. Functionality: A garage door that is appropriately sized ensures that it operates smoothly and efficiently. If the door is too small, it might not provide enough clearance for vehicles to enter and exit comfortably. If it’s too large, it could be unwieldy to open and close and may require additional support.
  2. Vehicle Access: Many people use their garages to store vehicles, and having a correctly sized door allows for easy access. The door needs to be wide and tall enough to accommodate your vehicles, including SUVs, trucks, and other larger vehicles. The last thing you want is to have to squeeze your vehicle through a door that’s too small, risking damage to your vehicle or the door itself.
  3. Storage and Workspace: Garages often serve as storage areas or workshops in addition to vehicle storage. Having a properly sized door ensures that you can make the most of the available space for storage and other activities.
  4. Energy Efficiency: A properly sized garage door can help maintain the energy efficiency of your home. If the door doesn’t fit well or doesn’t seal properly, it could lead to drafts, heat loss, or increased energy costs.
  5. Safety and Security: A correctly sized garage door enhances the safety and security of your property. It helps prevent unauthorized access and reduces the risk of break-ins.


Let’s Recap!

Choosing the right garage door size is crucial for ensuring functionality, aesthetics, and practicality. It’s recommended to consult with a professional garage door installer to determine the appropriate size based on your specific requirements and the available space.


Selecting appropriately sized garage doors yields several advantages. Properly fitted doors enhance security by eliminating gaps and unauthorized access. Tight-fitting doors also prevent pest infiltration and conserve interior temperatures, contributing to a more comfortable and energy-efficient garage environment.
