Quick Verdict
For a two-car garage, one double door is cheaper and gives a cleaner facade; two single doors add redundancy and flexibility but cost more. A single double door is the most common, budget-friendly choice. Two singles make sense when you want a center post for structure, separate access, or a specific architectural look. Both are common across Orange County.
Single vs Double Door at a Glance
| Dimension | Two Single Doors | One Double Door |
|---|---|---|
| Cost (installed) | Higher (2 doors + 2 openers) | Lower (1 door, 1 opener) |
| Redundancy | One works if other fails | Whole bay down if it fails |
| Facade look | Symmetrical, traditional | Clean, modern, open |
| Vehicle access | Separate per bay | Wide, easy for big vehicles |
| Structural | Center post between | No center post |
| Flexibility | Independent operation | Single operation |
| Best for | Redundancy, traditional facades | Cost, wide access, modern look |
Two Single Doors Overview
Two single doors (typically 8–9 ft wide each) side by side, each on its own opener, with a structural post between them. This is the classic look on many traditional and older homes.
Pros:
– Redundancy — if one door or opener fails, the other still works
– Independent operation (open just one bay)
– Symmetrical, traditional curb appeal
– Center post adds structural support
– Smaller doors mean lighter springs/openers per side
Cons:
– Higher total cost (two doors, two openers, two sets of springs)
– More hardware to maintain
– Narrower individual openings (tight for large vehicles)
One Double Door Overview
A single wide double door (typically 16 ft) covering the whole two-car bay, on one opener. This is the most common modern setup and the budget-friendly choice.
Pros:
– Lower cost — one door, one opener, one spring system
– Clean, open, modern facade
– Wide opening — easy for trucks, SUVs, boats
– No center post to navigate
– Simpler to maintain (one system)
Cons:
– No redundancy — if it fails, the whole bay is stuck
– Heavier door needs robust springs and opener
– Less traditional look on some home styles
Which Is Cheaper?
One double door. You’re buying a single door, one opener, and one spring system instead of doubling up on all three — so the upfront and long-term maintenance costs are lower. That’s a big reason the single double door is the most common choice for OC two-car garages. See Garage Door Installation Cost for numbers.
Which Looks Better?
It depends on your home’s architecture. Two single doors give a symmetrical, traditional look that suits many classic and craftsman homes. One double door reads cleaner and more modern, and is the norm on contemporary builds. Neither is “better” — it’s about matching your facade. We can show renderings of both for your home.
Cost Comparison
In Orange County, one double steel door installs for about $1,500–$3,500, while two single doors run higher because you’re buying two doors and two opener systems — often $2,500–$5,000+ combined depending on materials. See our Garage Door Installation Cost page.
Best For…
- Lowest cost: one double door

- Traditional symmetrical look: two single doors
- Independent bay access: two single doors
Our Orange County Recommendation
For most OC two-car garages, we recommend one double door — it’s more affordable, gives wide access for today’s larger vehicles, and suits the clean look most homeowners want. We recommend two single doors when a homeowner specifically wants redundancy, has a traditional facade that calls for symmetry, or wants independent bay access. We’ll factor in your home’s style and how you use the garage before recommending one.

Frequently Asked Questions
Is one double door cheaper than two single doors?
Yes. One double door means a single door, opener, and spring system, so it’s cheaper to buy and maintain than two of everything.
Which is better for a two-car garage?
A double door for cost and wide access; two singles for redundancy and a traditional look. Most OC homes use a single double door.
Can I replace two single doors with one double?
Sometimes — if the center post can be removed and the structure supports it. We can assess whether converting is feasible for your garage.
Which is better for large vehicles?
One double door — its wide opening accommodates trucks, SUVs, and boats more easily than a narrower single door.
