Single-car versus double-car garage door pricing

Door size is the single biggest factor after material choice in determining what you will pay. A single-car door (typically 9 feet wide by 7 feet tall) costs substantially less in both materials and labor than a double-car door (typically 16 feet wide by 7 feet tall). The cost difference is not simply double, because some fixed costs like labor setup time and hardware are shared.

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+

Two single doors versus one double door

Homeowners with two-car garages have a choice: one wide double door or two narrower single doors side by side. Two single doors cost more in total materials and installation but offer individual control, better curb appeal variety, and a stronger visual break across a wide garage face. One double door is the simpler and often cheaper option when the rough opening already accommodates it. The structural header required for a 16-foot opening also costs more than two 9-foot headers, so factor that in if you are building new or modifying an existing opening.

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 garages
Advantage of one double: Lower upfront cost, one opener, simpler framing

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, so 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, sticking to standard dimensions saves money and shortens wait times.

How height affects price

Standard residential door height is 7 feet. High-lift conversions to 8 or 9 feet are available but require longer tracks and modified spring systems. The upgrade adds $300 to $800 in hardware and labor. If you have a taller vehicle or want to maximize clearance, confirm the ceiling height in your garage can accommodate the additional track run before ordering.

Get quotes from a licensed installer for your specific opening dimensions before ordering any door. Field measurements matter more than nominal sizes when calculating what will actually fit.

Frequently asked questions

What is the most common garage door size? The 9 x 7 foot single and 16 x 7 foot double are the most common standard residential sizes in the US. Most off-the-shelf doors at home improvement stores are built to these dimensions.

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 an appropriate header. This adds $500 to $1,500 or more in carpentry and framing costs beyond the door itself.

Does door size affect energy efficiency? Yes. A larger door means more surface area losing heat or cool air if it is uninsulated. Insulated doors become more valuable as door size increases, especially for attached garages in climates with cold winters or hot summers.

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 offer operational flexibility. Stick to standard sizes to avoid custom premiums and long lead times. Always measure the rough opening before ordering.
