Single vs Double Garage Door Cost: Size-by-Size Comparison
A single-car garage door (9 x 7 ft) costs $700 to $1,800 installed. A double-car door (16 x 7 ft) runs $900 to $3,000. Two separate single doors on a two-car garage total $1,400 to $3,600 combined, which is more than one double door, but they operate independently and often look better on wide garage faces.

Cost by door size
| Door size | Common use | Material cost | Installed cost |
|---|---|---|---|
| 8 x 7 ft (single) | Tight single-car garage | $250 to $800 | $600 to $1,400 |
| 9 x 7 ft (single) | Standard single-car | $300 to $1,200 | $700 to $1,800 |
| 10 x 7 ft (single) | Wider single or truck | $350 to $1,400 | $750 to $2,000 |
| 12 x 7 ft (single wide) | Large single or small double | $400 to $1,600 | $850 to $2,200 |
| 16 x 7 ft (double) | Standard two-car garage | $600 to $2,500 | $900 to $3,000 |
| 18 x 7 ft (double wide) | Large two-car or RV | $700 to $3,000 | $1,000 to $3,500+ |
What is the most common garage door size?
The 9 x 7 foot single and 16 x 7 foot double are the standard residential sizes across most of the U.S. Stock doors at home improvement stores are built to these dimensions. Staying with standard sizes avoids custom-order premiums and the two-to-six-week lead times that non-standard sizes typically carry.
Two single doors versus one double door
Homeowners with two-car garages face a choice: one wide double door or two narrower single doors side by side.
- One 16 x 7 double door installed: $900 to $3,000
- Two 9 x 7 single doors installed: $1,400 to $3,600 combined
- Advantage of two singles: independent operation, easier partial replacement, often preferred for curb appeal on wide garage faces
- Advantage of one double: lower upfront cost, one opener, simpler framing
A structural header for a 16-foot opening costs more than two 9-foot headers, so factor that in if you are building new or modifying an existing opening.
Can I put a double door where I currently have two singles?
Yes, but it requires structural work to create a single wider rough opening with a proper header. That framing adds $500 to $1,500 or more in carpentry beyond the door cost itself. Before pursuing this conversion, confirm with a licensed contractor that the wall framing can support the wider opening without disturbing anything above it.
Non-standard and custom sizes
Oversized openings for RVs, boats, or large trucks require custom-ordered doors. A 10-foot-tall or 18-foot-wide door is not a stock item at most dealers. Expect lead times of two to six weeks and price premiums of 20 to 50 percent over standard sizes. If you are planning a new build, standard dimensions save money and shorten wait times considerably.
How height affects price
Standard residential door height is 7 feet. High-lift conversions to 8 or 9 feet require longer tracks and modified spring systems, adding $300 to $800 in hardware and labor. If you have a taller vehicle or want more clearance, confirm the ceiling height in your garage can accommodate the additional track run before ordering. Your installer can measure headroom and confirm compatibility during the quote visit.
Does door size affect energy efficiency?
Yes. A larger door has more surface area for heat loss or gain when uninsulated. The value of insulation increases with door size, especially for attached garages in cold-winter or hot-summer climates. For a 16 x 7 foot double door on an attached garage in the Midwest or Northeast, upgrading from non-insulated to polyurethane-insulated is worth the additional $200 to $400. See the insulated door cost guide for a full breakdown.
Bottom line
A standard single-car door runs $700 to $1,800 installed; a double-car door costs $900 to $3,000. Two separate single doors on a two-car garage cost more in total but give you independent operation. Stick to standard sizes to avoid custom premiums and long lead times. Measure the rough opening before ordering and get a written quote from a licensed installer.
