Choosing the right garage door is about more than aesthetics; size, fit, and function matter. Many homeowners ask: What are the standard garage door sizes? Understanding door dimensions, door width, door height, and the standard dimensions for single and double doors ensures your garage is functional, safe, and stylish.
This guide covers everything from residential garage sizes to custom garage doors, plus tips on how to measure your garage for a perfect fit.
1. Standard Dimensions for Single-Car Garages

Single-car garages are designed to fit one vehicle comfortably. The most common door sizes provide enough clearance for daily use and some storage.
- 8 ft x 7 ft – Ideal for compact and mid-sized cars.
- 9 ft x 7 ft – Offers extra width for larger vehicles.
- 10 ft x 7 ft – Perfect for trucks, SUVs, or wider garage doors.
Tip: Check your vehicle’s height before purchasing. Some homeowners prefer an 8-foot door height for taller vehicles.
Garage dimensions for single-car garages usually range from 12–16 ft wide and 20–24 ft deep, giving enough space to park, walk around, and store tools.
2. Double Door Garage Sizes

A double-door garage fits two vehicles side by side, making it ideal for families with multiple cars or larger residential garages.
- 14 ft x 7 ft – Fits most standard cars.
- 16 ft x 7 ft – The most popular double door size.
- 18 ft x 7 ft – Provides extra space for wider vehicles or storage.
Tip: Consider garage door dimensions carefully if you want a garage size that can accommodate taller vehicles, with a door height of 8 ft for convenience.
Standard dimensions for double garages are usually 20–24 ft wide and 20–24 ft deep, ensuring a comfortable fit for two cars.
3. Oversized and Custom Garage Door Sizes

For RVs, trucks, or commercial vehicles, oversized garage doors are a must. Custom garage doors are also popular for unique home designs.
- 12 ft x 12 ft – Standard for most RVs.
- 14 ft x 14 ft – Fits larger RVs, buses, or trucks.
- Custom sizes – Available to fit your specific garage dimensions or design preferences.
Tip: Always measure the width and height of your vehicle, then add clearance to choose the correct door size.
Measuring Your Garage Door for the Perfect Fit
Before buying a new garage door, accurate measurements are essential. Follow these steps to ensure your door fits perfectly:
- Door Width – Measure the interior width of the garage opening in inches.
- Door Height – Measure from the floor to the top of the opening.
- Side Clearance – Space needed for tracks and hardware.
- Headroom – Distance above the opening for smooth operation.
- Depth of Garage – Check your garage dimensions to confirm adequate space.
Pro Tip: Use a level and tape measure for accurate measurements, or hire a professional installer.
Choosing the Right Garage Door
Selecting a garage door goes beyond door dimensions:
- Vehicle Type – SUVs and trucks need taller door height and wider door width.
- Garage Usage – Storage or workshop space may require larger garage door sizes.
- Material – Steel for durability, wood for aesthetics, or insulated doors for energy efficiency.
- Style & Size – Custom garage doors allow homeowners to match home architecture while optimizing garage dimensions.
