A garage door size guide helps you find the right door dimensions for your vehicle type and garage bay. Get recommended door width, height, and rough opening requirements.
How to Choose the Right Garage Door Size
Garage door size depends on your widest vehicle, the number of parking spots, and your garage's structural opening. When in doubt, go bigger — a wider or taller door costs little more but provides much better comfort and usability.
Rough Opening vs Door Size
The rough opening (framed opening in your garage wall) is typically 2 inches wider and 2 inches taller than the finished door size. This allows for door hardware and weatherstripping.
FAQ
What is the standard single garage door size?
The standard single-car garage door is 9 feet wide × 7 feet tall. Some older homes have 8×7 doors. Modern SUVs and trucks fit better in 9 or 10-foot wide openings. Taller doors (8 feet) are popular for pickup trucks.
What is the standard double garage door size?
Standard double garage doors are 16 feet wide × 7 feet tall, or 16×8 for pickup trucks and SUVs. Some homes use an 18-foot door for more clearance between cars.
What clearance does a garage door need?
Most standard doors need 4-12 inches of headroom above the door for the opener track. Side room is typically 3.75 inches on each side. Torsion spring openers need about 10-12 inches of headroom.
Can I get a custom garage door size?
Yes, most manufacturers offer custom sizes. Common custom widths are 10 and 12 feet for single bays. Custom heights of 8 or 9 feet accommodate RVs and lifted trucks.
