Standard Garage Door Sizes for Homes: Complete & Reliable Dimensions Guide 2025
When planning a new garage or replacing your existing door, knowing the right garage door size is essential for both functionality and curb appeal. From compact single-car garages to oversized RV spaces, standard garage door sizes make installation easier, cost-effective, and widely available. This 2025 guide covers typical garage door dimensions, measuring tips, and the latest design trends to help you choose the perfect fit.
What Are the Typical Garage Door Sizes?
Most garage door dimensions fall into standard ranges, ensuring compatibility with common vehicles. Choosing a standard size often means lower costs and quicker installation compared to custom garage doors.
Widths: 8 ft, 9 ft, 10 ft, 12 ft, 16 ft, and 18 ft
Heights: 7 ft, 8 ft, and occasionally 9–10 ft for taller vehicles
Common Dimensions for Single-Car Garage Doors
A single-car garage door is designed for one vehicle, making it a popular choice for smaller homes.
Width: 8 ft to 10 ft
Height: 7 ft to 8 ft
For sedans and compact SUVs, 8×7 ft works well, but larger SUVs or trucks benefit from a 9×8 ft or 10×8 ft garage door.
Standard Sizes for Double-Car Garage Doors
A double-car garage door is the most common option for modern homes, offering enough space for two vehicles side by side.
Width: 16 ft (standard) to 18 ft
Height: 7 ft to 8 ft
These doors are ideal for families and offer convenient access without needing multiple smaller doors.
Triple-Car Garage Door Measurements
Homes with larger garages may need a three-car garage door layout:
Three single doors (8–10 ft wide each), or
One double-car garage door (16–18 ft) + one single-car garage door (8–10 ft)
This setup allows flexibility for different vehicle types, storage, or workshop space.
RV and Oversized Garage Door Options
For RVs, boats, and lifted trucks, oversized garage doors are essential.
Width: 12 ft to 14 ft
Height: 12 ft to 16 ft
These large garage doors often require custom framing, but many manufacturers now offer standard RV garage door dimensions in the 12×12 to 14×14 range.
