When building, renovating, or replacing a garage, one of the most important decisions is choosing the right garage door size. A properly sized garage door ensures smooth parking, provides room for storage, and adds long-term value to your home. Fortunately, most U.S. homes—including those in Katy, TX—follow standard garage door sizes, making it easier for homeowners to find the perfect fit.
This guide covers the most common garage door dimensions for single-car, double-car, and oversized garages. You’ll also learn when to choose a custom option and how garage door height can make a big difference.
Why Standard Garage Door Sizes Matter
Garage door dimensions affect more than just appearance. They influence:
- Vehicle clearance – SUVs, trucks, and RVs require taller and wider openings.
- Convenience – A wider door makes parking easier for families with multiple vehicles.
- Property value – Homes with standard garage door sizes appeal more to potential buyers.
- Storage – Larger garage doors allow for bikes, lawn equipment, and tools in addition to cars.
In short, choosing the right garage door size saves headaches and increases your home’s functionality.
Standard Garage Door Sizes for Single-Car Garages
For one-car garages, these are the most common sizes:
- 8 feet wide x 7 feet high – A classic option, still found in older homes. Best for compact cars.
- 9 feet wide x 7 feet high – Considered the modern standard, providing more clearance for SUVs.
- 10 feet wide x 7–8 feet high – Great for oversized single vehicles, lifted SUVs, or homeowners who need extra room.
👉 Tip: If you’re planning to buy a bigger vehicle in the future, go for at least 9 feet wide to avoid costly renovations later.
Standard Garage Door Sizes for Double-Car Garages
Two-car garages are the most popular style in modern U.S. homes. Standard sizes include:
- 16 feet wide x 7 feet high – The most common double-car garage door size.
- 18 feet wide x 7–8 feet high – Offers extra clearance, especially for large trucks or SUVs.
Many homeowners prefer the 18-foot option for easier parking and added convenience. Even if you only park two smaller cars, the extra space prevents dings and scratches.
Oversized & RV Standard Garage Door Sizes
Some vehicles simply won’t fit into standard sizes. For RVs, lifted trucks, and motorhomes, larger dimensions are necessary:
- Height: 12–14 feet
- Width: 10–12 feet (sometimes more depending on design)
These oversized garage doors are often custom-built but are considered essential for RV owners or homeowners with commercial vehicles.
Height Options in Standard Garage Door Sizes
Most residential garage doors are 7 feet high, but many newer homes are moving toward 8 feet high to accommodate taller vehicles.
- 7 feet high – Standard in most neighborhoods.
- 8 feet high – Ideal for SUVs, minivans, and pickups.
- 9–10 feet high – Best for custom builds or RV garages.
👉 Positive benefit: Choosing an 8-foot garage door today future-proofs your home for larger vehicles.
Custom Garage Door Sizes
Sometimes custom garage door sizes are the only solution. This is common when:
- Renovating older homes with non-standard openings.
- Designing luxury properties with unique architecture.
- Building garages for specialty vehicles.
Top manufacturers like Clopay, Amarr, CHI, and Wayne Dalton offer flexible sizing options. While pricier, they provide the perfect balance of fit, function, and curb appeal.
