Here’s a clear breakdown of the standard garage door sizes most commonly used in the U.S. (including Katy, TX and nationwide):
Standard Garage Door Sizes
Single-Car Garage Doors
- 8 feet wide x 7 feet high (most common for smaller garages)
- 9 feet wide x 7 feet high (modern standard, allows more clearance for SUVs)
- Some homes use 10 feet wide x 7 or 8 feet high for oversized single vehicles or extra storage space.
Double-Car Garage Doors
- 16 feet wide x 7 feet high (the most common double-car size in the U.S.)
- Some modern homes use 18 feet wide x 7 or 8 feet high for larger trucks or wide driveways.
RV & Oversized Garage Doors
- 12–14 feet high
- 10–12 feet wide (sometimes wider depending on design)
- Common for motorhomes, lifted trucks, or commercial-style garages.
Height Options
- Standard residential garage doors are 7 feet high.
- Many newer homes, especially in areas with SUVs and trucks, have 8 feet high doors.
- Custom builds can go 9–10 feet high for taller vehicles.
Custom Garage Doors
While these are the most standard garage door sizes, nearly every manufacturer (Clopay, Amarr, CHI, Wayne Dalton, etc.) offers custom sizing to fit non-standard openings—common in older homes, renovations, or luxury properties.
