Standard Garage Door Sizes

Whether you’re building a new home or 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 Oregon City Garage Door, our goal is to make your 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 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. These are perfect for family households or for homeowners needing extra space for workshop equipment, storage, or recreational vehicles like ATVs and golf carts.

Common standard 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 Garages

A three-car garage offers the ultimate flexibility for multiple vehicles 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 Single Doors: Three separate 9-foot or 10-foot doors, separated by support posts.

Choosing the Best Garage Door Size for Your Home

A new door gives you better customization options, especially if your entire garage is new. Ideally, having extra space when measuring allows you to store more than just your vehicle, and you can utilize the space to its full potential.

The right garage door size depends on your vehicles, your garage’s construction, and your lifestyle. If you’re replacing an existing door, the choice is often straightforward. However, for a new build or a major remodel, you have more flexibility.

A new garage door gives you incredible customization options. We particularly recommend our Clopay collections for their vast selection of styles, colors, insulation levels, and window designs. Planning for a slightly wider or taller door than you think you need can be a smart long-term investment, providing flexibility for future vehicles and making everyday use more convenient.

Custom Garage Door Sizes for RVs and Special Applications

Do you own an RV, a boat, or a lifted truck? 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 12 feet wide or more. Building a garage for a recreational vehicle usually requires a detached structure designed specifically for these larger dimensions. Our team can help you source and install a high-quality door built to your exact custom specifications.
