When you plan a new garage or think about changing your old garage door, one question always comes up: How wide is a garage door? It may seem simple, but garage door width affects everything from parking to storage to curb appeal. Picking the right size is not just about fitting your car. It’s about safety, convenience, and even your home’s value. People often overlook how garage door width impacts daily life until it’s too late—like when you can’t open your car door inside the garage or your new SUV barely squeezes through.
In this guide, you’ll learn what garage door widths are common, how to measure, which sizes suit different needs, and what mistakes to avoid. We will dig into single and double garage doors, custom options, special needs, and regional differences.
By the end, you’ll know exactly how to choose the right width for your garage door, backed by real data and practical advice.
Most homes in the US use standard garage door sizes. These sizes are made to fit common vehicles and garage layouts.
A single garage door is made for one car. Most single doors are:
The 8-foot and 9-foot sizes are the most popular, with 9 feet now more common due to larger vehicles.
Most new builds now feature 9-foot doors because car sizes have grown. Older homes often have 8-foot doors, which can feel cramped.
A double garage door fits two cars side by side. Standard double garage door widths are:
The 16-foot size dominates new construction for two-car garages. Some older or custom garages use 12 or 18 feet.
Garage doors can be made in custom widths. For example, you might find:
Custom widths are used when space is unusual, or needs are special—like fitting an RV or multiple motorcycles.
Manufacturers make garage doors in standard sizes because:
Standard sizes also help when you need a new door years later. If your door is a common width, you can quickly find parts or replacements.

Knowing your garage’s actual space is essential. Many people guess, but mistakes lead to problems later. Here’s how to measure:
Pro tip: Always measure the opening—not the old door. The frame may differ from the door size, especially after repairs.
If unsure, ask a professional installer to measure for you. This prevents expensive errors.
The size of your garage door must match your vehicle type. Here’s a guide for common vehicles:
Width is only part of the story. Most garage doors are 7 feet high (84 inches), but some are 8 feet high (96 inches) for taller vehicles. Sometimes height can affect how wide a door feels—especially if your vehicle is tall and wide.
A wider door does not always mean easier access for tall vehicles. Make sure to check both dimensions.
Garage door sizes are not the same everywhere. In Europe, for example, doors are often:
In Australia, common sizes are:
These differences are caused by vehicle sizes, building codes, and climate. If you move internationally or buy a door from another country, check compatibility.

Sometimes, your garage needs a special size. Reasons include:
Custom doors cost more but solve unique problems. You can order any width, but most manufacturers limit custom widths to 24 feet for safety.
Custom doors are more expensive. Standard doors cost $700–$1,500 for single, $1,200–$2,500 for double. Custom sizes can run $2,000–$5,000 or more, especially for extra-wide or tall doors.
Local building codes often set minimum and maximum garage door widths. For example:
Always check city or county codes before buying. Some areas restrict custom sizes to keep neighborhoods uniform.
Garage door width impacts:
Many homeowners regret choosing a narrow door after buying a larger vehicle. Extra width is rarely wasted.

Some homeowners need wider doors for:
If you need extra width for accessibility, talk to an installer about ADA (Americans with Disabilities Act) standards. ADA recommends at least 10 feet wide for easy access.
Wider doors often need stronger openers. Automatic openers must match the width and weight of your door. For doors over 16 feet wide, choose a heavy-duty opener. Otherwise, the opener may fail.
Many modern openers come with smart features, like remote access and safety sensors, which are useful for wider doors.
Wider doors need more maintenance. The bigger the door, the heavier it is, which means:
Repairs on wide doors cost more, but maintenance prevents big problems. Always check the door’s balance and hardware every six months.
