Quick answer: A single-car garage door is 8×7, 9×7 or 10×7 (width × height in feet) — 9×7 is the most common in GTA homes. A double-car (two-car) garage door is 16×7 as standard, with 15×7 for slightly narrower bays. The width is always stated first. Royal installs all standard sizes across Toronto and the GTA — single from $1,350, double from $2,300 + tax, fully installed. Design your door or book a free measurement.
How Garage Doors Are Measured
Garage doors are sized as width × height in feet, with the width always first. A "9×7" door is 9 feet wide and 7 feet tall; a "16×7" is 16 feet wide and 7 feet tall. That number describes the door panel, which is matched to the finished opening in your garage wall — not the old door you are replacing. When you order a new door you also need to know your headroom, sideroom and backroom (covered in the measuring section below), because those determine which spring and track system fits.
In the GTA, almost every residential door is a sectional door 2 inches thick and R-18 insulated — the type Royal supplies — with the panel size falling into one of the standard single or double dimensions covered here.
Standard Garage Door Sizes Chart
Here is the full range of standard residential garage door sizes used across Ontario, with the two most common — 9×7 single and 16×7 double — highlighted.
| Type | Width × Height | Best for | Installed from (+ tax) |
|---|---|---|---|
| Single-car (narrow) | 8×7 | Compact cars, older Toronto homes | $1,350 |
| Single-car (standard) | 9×7 — most common single | Most single garages, SUVs, minivans | $1,500 |
| Single-car (wide) | 10×7 | Full-size trucks, workshop bays | $1,650 |
| Double-car (narrow) | 15×7 | Slightly narrower two-car bays | $2,300 |
| Double-car (standard) | 16×7 — most common double | Most two-car garages in the GTA | $2,300 |
Heights of 8 feet are available on most widths for taller vehicles, roof boxes and lifted trucks. Window inserts add $125 per window. A new opener is from $630 and is not included in the door price. Prices in CAD, taxes extra. See the full pricing page for every option.
Single-Car Garage Door Sizes (8×7, 9×7, 10×7)
A single garage door covers an opening built for one vehicle. Three widths cover almost every situation in the GTA:
- 8×7 — the narrow single. Common in Toronto homes built before the 1980s when cars were smaller. It fits sedans and compact cars but leaves tight clearance for a wide SUV or pickup. Installed from $1,350 + tax.
- 9×7 — the standard single. The single garage door size you will see on most homes built since the 1990s. The extra foot of width gives roughly 12 inches of breathing room on each side and clears SUVs and minivans easily. Installed from $1,500 + tax. If you are unsure, this is the safe default.
- 10×7 — the wide single. Best for full-size trucks, or single bays that double as a workshop where you want room to store tools and bikes beside the vehicle. Installed from $1,650 + tax.
Height tip: all three are 7 feet tall as standard. If you drive a lifted truck, cargo van or anything with a roof rack or ski box, step up to an 8-foot-tall door — the extra 12 inches makes a real difference and saves you removing roof accessories every time you park.
Double-Car (Two-Car) Garage Door Sizes (15×7, 16×7)
A double garage door — also called a two-car garage door — spans one wide opening built for two vehicles, with no centre post. There are two standard widths:
- 15×7 — the narrow double. A slightly narrower two-car door for openings that fall just under 16 feet. It still spans both bays with no centre post and is priced the same as the 16×7. Installed from $2,300 + tax.
- 16×7 — the standard double. The most common double-car garage door size in the GTA, fitted to the majority of homes built from 1990 onward. It comfortably holds two average vehicles and is the most cost-effective two-car option. Installed from $2,300 + tax.
As with singles, 8-foot heights (15×8 or 16×8) are available where you need extra headroom for tall vehicles or roof-mounted carriers.
Single Door vs Double Door: Which Should You Choose?
If you have a two-car garage, you can fit one wide double door or two separate single doors. Here is how they compare so you can choose with eyes open.
| Consideration | One double door (15×7 / 16×7) | Two single doors (2 × 9×7) |
|---|---|---|
| Up-front cost | Lower — one door, one opener | Higher — two doors, two openers, a centre post |
| Look | Clean, uninterrupted, modern | Symmetrical, traditional, carriage-style friendly |
| Weather sealing | Good | Slightly better (less span to seal, plus the post) |
| Redundancy | If the opener fails, neither car gets out easily | One car can still get out if one door fails |
| Parking room | Most flexible — no post to steer around | Tighter — the centre post narrows each bay |
For most GTA two-car garages, a single 15×7 or 16×7 double door is the practical, lower-cost pick. Two single doors make sense when you want a particular carriage-house aesthetic, slightly better insulation, or the independence of two openings. Either way, our door designer lets you preview both before you decide.
How to Measure Your Garage Door Opening
Five measurements tell us exactly which door and hardware system fits. Always measure the finished opening and record everything in feet and inches.
- Width. Measure between the inside faces of the left and right jambs at the widest point. Check it at the floor and again near the top — if they differ, use the smaller number.
- Height. Measure from the floor to the underside of the header (the horizontal beam above the opening). Floors are not always level, so check both sides.
- Headroom. The space from the top of the opening up to the ceiling. A standard torsion-spring system needs about 12 inches; low-headroom kits work with less.
- Sideroom. The wall space on each side of the opening, where the vertical tracks mount. Allow roughly 3.75 inches minimum per side.
- Backroom. How far the garage extends back from the opening. The door needs to slide overhead, so plan for about the door height plus 18 inches.
You do not have to do this alone. Royal includes free, professional measurements with any installation quote — we confirm the opening, recommend the right size, and quote the all-in installed price on the spot. Book a free measurement.
Garage Door Sizes in Older Toronto & GTA Homes
Garage door sizing in the GTA tracks closely with when a home was built:
Pre-1980 Toronto homes
Established neighbourhoods — the Annex, High Park, Leaside, older parts of Etobicoke and Scarborough — were built for smaller cars and frequently have 8×7 or even 8 ft × 6 ft 6 in single openings. When replacing one of these, you can fit a door to the existing opening or widen it to take a standard 9×7 for better clearance and resale appeal.
Suburban builds (1980–2010)
Homes from the suburban expansion of Mississauga, Brampton, Vaughan and Richmond Hill almost always use standard sizes: 9×7 single bays and 16×7 doubles. Replacement doors drop straight in with no opening modification needed.
Modern custom homes (2010–present)
Newer GTA builds increasingly specify 16×8 doubles and 10×8 singles to clear today's full-size pickups, large SUVs and roof-mounted gear. If you are building or renovating, it is worth upsizing a little to future-proof for growing vehicles.

Frequently Asked Questions
What is the standard size for a single-car garage door?
A standard single-car garage door is 8 feet wide by 7 feet tall (8×7) or 9 feet wide by 7 feet tall (9×7), with 10×7 used for wider single bays. The 9×7 is the most common single garage door in GTA homes built since the 1990s — it clears most sedans, minivans and mid-size SUVs comfortably. Older Toronto homes often have the narrower 8×7. At Royal Garage Doors a supply-and-install 8×7 single starts from $1,350 + tax, a 9×7 from $1,500, and a 10×7 from $1,650.
What is the standard size for a double-car (two-car) garage door?
A standard double-car garage door — also called a two-car garage door — is 16 feet wide by 7 feet tall (16×7). A 15×7 double covers slightly narrower two-car openings. Both are 7 feet tall as standard, with 8-foot heights available for lifted trucks and roof racks. Installed pricing at Royal starts from $2,300 + tax for a 15×7 or 16×7 double.
Is one double garage door or two single doors better?
A single 15×7 or 16×7 double door is usually cheaper to buy and install than two separate single doors and gives a clean, uninterrupted look. Two single 9×7 doors cost more up front and need a centre post, but they seal slightly better, are easier to operate independently, and let one car still get out if one opener fails. For most GTA two-car garages a single double door is the practical, lower-cost choice.
How do I measure my garage door opening?
Measure the finished opening, not the old door. (1) Width — measure between the inside faces of the side jambs at the widest point. (2) Height — measure from the floor to the underside of the header. (3) Headroom — the space from the top of the opening to the ceiling (a standard torsion system needs about 12 inches). (4) Sideroom — the wall space on each side of the opening (about 3.75 inches minimum per side for the tracks). (5) Backroom — the depth into the garage, typically the door height plus about 18 inches. Record everything in feet and inches. Royal includes free professional measurements with any installation quote.
Can I order a custom-size garage door for an odd opening?
Yes. If your opening does not match a standard size, custom doors are available in roughly 3-inch width increments and heights well above the standard 7 and 8 feet. Custom doors cost more than standard sizes and have a longer lead time. In many older GTA homes it can actually be cheaper to slightly modify the opening to fit a standard 9×7 than to order fully custom — we assess which path is more cost-effective during the free site visit.
Do older Toronto homes have non-standard garage door sizes?
Often, yes. Homes built before about 1980 in established Toronto neighbourhoods were sized for smaller cars and frequently have 8×7 — or even 8 feet by 6 feet 6 inches — openings. When replacing a door in an older home you can either order a door to fit the existing opening or widen it to take a standard 9×7. Our technicians confirm the exact opening on site so the new door fits and seals correctly.
What does a new garage door cost by size in the GTA?
Royal Garage Doors supply-and-install pricing (+ tax) is: 8×7 single from $1,350, 9×7 single from $1,500, 10×7 single from $1,650, 15×7 double from $2,300, and 16×7 double from $2,300. Every price includes the door panels, all hardware, weatherstripping, professional installation, removal and disposal of the old door, and a safety check. Window inserts are +$125 per window and a new opener (not included) is from $630. A door-only delivery without installation starts from $850.
