Standard Garage Door Sizes in Oklahoma: Single, Double, and Oversized Options
Before you shop colors, insulation, or brands, you have to nail the one measurement that determines everything else: the size of your opening. Get the size wrong and nothing else matters. This guide walks Oklahoma City homeowners through the standard single, double, and oversized dimensions we install every week across the metro — and how to figure out which one your home actually needs.
The Sizes You'll Actually See in OKC Neighborhoods
Oklahoma's housing stock ranges from mid-century single-car garages in older Bethany and Del City neighborhoods to sprawling three- and four-car garages in newer Edmond and Piedmont developments. Despite that range, the vast majority of doors fall into a handful of standard sizes that manufacturers stock and build efficiently.
| Configuration | Typical Width | Typical Height |
|---|---|---|
| Single car | 8 or 9 feet | 7 feet |
| Standard double | 16 feet | 7 feet |
| Tall double (trucks/SUVs) | 16 or 18 feet | 8 feet |
| Oversized / RV / shop | 10 to 20+ feet | 9 to 12 feet |
Single-car doors: 8x7 and 9x7
The 9-foot-wide, 7-foot-tall door is the workhorse of Oklahoma residential construction. You'll find it as a standalone door on smaller lots and as a paired opening on homes that use two separate single doors instead of one wide double. The 8-foot width shows up mostly on older homes built before full-size trucks became the norm — and it's a tight fit for a modern crew-cab pickup with mirrors extended.
Double doors: 16x7 and 16x8
The 16x7 double is the single most common new-installation size we handle in the OKC metro. The 16x8 — one foot taller — has become increasingly popular in newer builds because it comfortably clears lifted trucks, roof cargo boxes, and full-size SUVs. If you drive a Suburban, an F-250, or anything with a roof rack, that extra foot of headroom is the difference between a relaxed daily pull-in and a scraped clearance bar.
Measure the opening, not the door
Garage doors are sized by the finished rough opening — the hole in the wall — not by the panel dimensions. Measure width and height at the opening, plus the headroom above it and the side room on each side. Standard installs need roughly 12 inches of headroom for a torsion spring; low-headroom kits exist for tight garages but change the hardware. When in doubt, we measure for free.
Oversized and Non-Standard Openings
Once you move past the 16-foot double, you're into custom territory — and it's more common in Oklahoma than in most states. Rural acreages around Piedmont, Tuttle, and Blanchard frequently have shop buildings with 10-, 12-, or 14-foot-tall doors to clear RVs, boats, trailers, and farm equipment. These openings demand more than just a bigger panel.
- ›Heavier springs: A taller, wider door weighs substantially more and needs a spring system engineered to that exact weight — not an off-the-shelf residential spring.
- ›High-lift or vertical-lift track: Tall doors often use high-lift tracks so the door travels farther up the wall before turning back, maximizing vertical clearance for RVs.
- ›Heavier-duty opener: Oversized doors frequently need a commercial-grade or jackshaft operator matched to the door's weight and cycle demands.
- ›Longer lead time: Custom sizes are built to order, so they're not a same-day swap the way a standard 16x7 replacement often is.
Why the Right Size Matters More in Oklahoma's Climate
Sizing isn't just about fitting the vehicle. A larger door is a larger thermal surface, and in a climate that runs from 140°F door-surface temperatures in July to ice-storm cold in January, that matters. A 16x8 uninsulated door radiates a lot more heat into an attached garage than a 9x7 does — which is why we steer owners of big double and oversized openings toward insulated, thermally-broken doors from brands like CHI Overhead Doors and DoorLink. Bigger openings also catch more wind load during storm season, so the door's construction and bracing become genuinely important, not just a spec sheet detail.
Quick tip before you buy
If you're replacing an existing door with the same size, you're usually in easy, fast territory. If you're widening or heightening the opening — say, going from 8 feet to 9 feet, or 7 feet to 8 feet — that involves framing changes, new tracks, and a re-engineered spring system. We only recommend and install brands we stand behind, and we'll tell you honestly whether a resize is worth it for your home.
Frequently Asked Questions
What is the most common garage door size in Oklahoma City?
The 16-foot-wide by 7-foot-tall double door is the most common size we install across the OKC metro, followed closely by the 9x7 single. Newer builds increasingly use the 16x8 for extra height to clear trucks and SUVs.
Can I replace a 7-foot-tall door with an 8-foot-tall one?
Sometimes, but it's not a simple panel swap. Adding height requires modifying the rough opening framing, installing new tracks, and re-engineering the spring system to the new door weight. We can assess your garage on-site and tell you whether the change is feasible and worthwhile.
How much headroom do I need above the opening?
A standard torsion-spring install needs roughly 12 inches of clearance above the opening for the spring assembly and tracks. Garages with less can often use a low-headroom track kit. We measure headroom and side room during every free estimate so the hardware matches your space.
