What Are Standard Residential Garage Door Sizes?

At Doorcare, we know that choosing the right garage door starts with understanding standard residential garage door sizes. Garage doors are not one size fits all, and selecting the correct dimensions helps improve safety, appearance, and daily convenience. Whether you are replacing an old door or planning a new build, size matters more than most homeowners realize.

In this guide, we explain standard residential garage door sizes used across Canada. We also share practical advice to help you decide what works best for your home, lifestyle, and long term needs.

Why Standard Residential Garage Door Sizes Matter

Standard residential garage door sizes exist to simplify manufacturing and installation. These sizes are designed to fit most homes while keeping costs predictable and repairs easier. When your garage opening matches a standard size, you benefit from faster installation and more design options. At Doorcare, we always recommend starting with standard sizing before exploring custom solutions.

Single car garages are very common in Canadian homes, especially in older neighbourhoods. These garages are designed to fit one vehicle comfortably with limited extra space. The most common single car standard residential garage door sizes include:

• 8 feet wide by 7 feet high
• 9 feet wide by 7 feet high

An 8 foot wide door works well for compact cars. A 9 foot wide door is often preferred today because it provides more room for parking and entry.

Double car garages are popular in newer homes and suburban developments. They allow space for two vehicles and additional storage. The most common double car standard residential garage door sizes are:

• 16 feet wide by 7 feet high
• 16 feet wide by 8 feet high

A 7 foot height is considered standard, while 8 foot doors are becoming more popular for larger vehicles. We often recommend taller doors for homeowners with SUVs or trucks.

Garage Door Height Options for Modern Vehicles

Vehicle sizes have changed significantly over the years. Many modern vehicles sit higher than older models.

Choosing the right height for your garage door helps prevent clearance issues. Standard residential garage door sizes usually range from 7 to 8 feet high, but some homes require taller openings for added comfort.

Some homes do not fit into standard sizing categories. This is common for custom homes or properties with unique designs. Oversized garage doors may be needed for:

• Recreational vehicles
• Boats or trailers
• Workshops or hobby spaces

While these are not considered standard residential garage door sizes, Doorcare offers solutions to ensure safety and reliability.

How to Measure Your Garage Door Opening Properly

Accurate measurements are critical when selecting a garage door. Even small errors can lead to costly delays or poor performance. We recommend measuring the width, height, headroom, and side room. Our technicians can also assist with professional measurements through our residential garage door services, ensuring everything fits correctly.

Standard residential garage door sizes are cost effective and widely available. Custom doors allow more flexibility in design and function but come at a higher price. Most homeowners find that standard sizes meet their needs perfectly. At Doorcare, we only suggest custom options when standard sizing is not practical or safe.

Different garage door materials can affect how a door operates within a standard opening. Steel, aluminum, and wood all behave differently under stress and temperature changes. Standard residential garage door sizes work well with most materials. However, heavier materials like wood may require reinforced hardware and professional installation.

Insulation plays a key role in energy efficiency, especially in Canadian climates. Properly fitted doors help maintain indoor temperatures. Standard residential garage door sizes allow for better sealing and insulation options. This helps reduce heat loss and improves overall comfort in your home.

How Garage Door Size Affects Curb Appeal

Your garage door often takes up a large portion of your home’s front exterior. The size and proportions impact visual balance. Choosing a standard residential garage door size that matches your home’s scale improves curb appeal. Doorcare helps homeowners select doors that enhance both function and appearance.

Attached garages often follow standard sizing more closely. Detached garages may have more flexibility in design. Even so, most detached garages still use standard residential garage door sizes to simplify maintenance. This makes replacement and repairs easier over time.

While standards are consistent across Canada, some regional preferences exist. Urban homes may use smaller doors, while suburban homes often feature wider openings. At Doorcare, we account for local building trends when recommending garage door sizes. This ensures compatibility with your home and neighbourhood.

Safety Factors Related to Garage Door Size

Garage door size affects weight, balance, and mechanical performance. Larger doors require stronger springs and openers. Using standard residential garage door sizes helps maintain safe operation. Our trained technicians ensure every installation meets safety guidelines and manufacturer requirements.

Not all garage door openers are suitable for every door size. Heavier or taller doors need more powerful systems. Standard residential garage door sizes pair easily with most openers on the market. Doorcare installs and services openers that are properly matched to your door size.

Larger garage doors experience more wear due to their weight and movement. Regular maintenance becomes even more important. Standard residential garage door sizes are easier to maintain because parts are readily available. Our maintenance programs help extend the life of your door.

Sometimes a garage door no longer meets your needs. This can happen when vehicles change or renovations occur. Replacing a door within standard residential garage door sizes is usually simpler than resizing the opening. Our team can help assess the best option for your situation.

Residential and Commercial Garage Door Differences

Residential garage doors differ from commercial ones in size and construction. Commercial doors are built for higher usage and larger openings. If you manage mixed use properties, Doorcare also offers professional commercial garage door services designed for durability and performance.

Local building codes may influence garage door dimensions. Height and clearance requirements vary depending on structure and location. Standard residential garage door sizes generally comply with most codes. Doorcare ensures every installation meets current regulations and safety standards.

Your daily habits play a role in selecting the right garage door size. Storage needs, parking comfort, and future plans should all be considered. We help homeowners choose standard residential garage door sizes that support their lifestyle today and in the future.

Even the right size door can fail if installed incorrectly. Professional installation ensures smooth operation and long term reliability. Doorcare’s experienced technicians handle everything from measurement to final testing. This gives you peace of mind from day one.

Understanding standard residential garage door sizes helps you make informed decisions that protect your investment and improve your home. The right size enhances safety, efficiency, and curb appeal while reducing future repair costs.
