Understanding standard garage door sizes is the first critical step when you’re building a new custom home in the Phoenix Valley or when it’s time to replace your existing garage door, getting the right measurements is the first critical step. While we offer a wide selection of doors from many quality vendors, we have a special partnership with Clopay® as our primary provider. We’ve found their superior product quality, outstanding support, and robust warranty make them the best choice for our customers, ensuring a beautiful and long-lasting investment.
At Integrity West Overhead Door, our goal is to make your Phoenix garage door installation a smooth and surprise-free experience. While our team is always ready to provide professional measurements, this guide will help you understand the standard garage door sizes available for your home.
A Guide to Standard Garage Door Dimensions
While custom doors are always an option, most garages are built to accommodate a few standard door sizes. When measuring, it’s crucial to consider more than just the door opening. You also need to account for:
- Headroom: The vertical space between the top of the door opening and the ceiling. This is needed for the door’s tracks, springs, and opener.
- Side Room (or Sideroom): The space on either side of the door opening, required for mounting the vertical tracks.
These clearance measurements are essential for a safe and functional installation. Now, let’s look at the most common door dimensions, which are typically presented as Width x Height.
Standard Single-Car Garage Door Sizes
A single garage door is designed for one vehicle but can vary in width to accommodate anything from a compact car to a large SUV or truck. The most common height for modern homes is 7 feet, but 8-foot-tall doors are also readily available for taller vehicles.
Common standard garage door widths for single-car doors include:
- 8′ x 7′
- 9′ x 7′ (A very popular choice, offering more room)
- 10′ x 7′
- 8′ x 8′
- 9′ x 8′ (Ideal for SUVs and trucks)
- 10′ x 8′
Standard Double-Car Garage Door Sizes
A double garage door provides a wide, convenient opening for two vehicles. In the Phoenix area, where protecting vehicles from the sun is paramount, a well-insulated double door can make a significant difference to your garage’s internal temperature.
Common standard garage door widths for double-car doors include:
- 16′ x 7′ (The most common double door size)
- 18′ x 7′
- 16′ x 8′ (Provides extra height for larger vehicles)
- 18′ x 8′
Configurations for Three-Car and Four-Car Garages
A three or four-car garage offers the ultimate flexibility for multiple vehicles, workshop space, and storage. Rather than one massive door, these garages typically use a combination of standard-sized doors for structural integrity and practicality.
The most common configurations are:
- One Double Door & One Single Door: For example, one 16-foot door next to one 9-foot door.
- Three or Four Single Doors: Separate 9-foot or 10-foot doors, often used in custom home designs.
Choosing the Best Garage Door for Your Phoenix Home
The right standard garage door size depends on your vehicles, your garage’s construction, and your lifestyle. For many in Arizona, especially seasonal residents or “snowbirds,” the garage is more than just a place for daily drivers. It’s secure, indoor storage for an RV, a boat, or multiple vehicles for extended periods.
Our collection of new garage doors gives you incredible customization options. We particularly recommend our Clopay collections for their vast selection of styles, colors, and insulation levels—including options with high R-values perfect for the desert climate. Planning for a slightly wider or taller door can be a smart long-term investment for future needs.
Custom Garage Door Sizes for RVs, Shops, and Barns
Do you own an RV, a large trailer, or have a detached workshop or barn? Standard doors won’t cut it. For these applications, you’ll need a custom-sized door. RV garage doors often need to be 12 to 16 feet tall and can be 10 to 14 feet wide. We specialize in sourcing and installing high-quality, durable doors for these unique structures, ensuring your valuable assets are protected and accessible.
