Garage Door Sizes: Every Standard Size, Measured

By the Garage Sized team · Updated October 7, 2026 · Figures from door and vehicle makers’ specs, Edmunds and ADAC

Garage doors are sold in a short list of standard sizes. Makers will build almost any size to order, but the doors stores stock are 8 or 9 ft wide for one car, 16 ft wide for two, and 7 ft tall. This page lists every standard size with exact measurements, shows which vehicles fit through each one, and covers the space a door needs around its opening.

Listing counts are from the size filters on homedepot.com, and lowes.com where noted, on October 7, 2026. They change by store and date, so read them as a sign of what is stocked, not as market share.

Makers’ own lists are longer than what stores carry. Clopay lists standard residential widths of 8, 9, 10, 12, 14, 15, 15½, 16 and 18 ft, and heights from 6 to 8 ft in 3-inch steps (all except 7 ft 3 in). Amarr keeps it shorter: singles 8, 9 or 10 ft wide, doubles 16, 18 or 20 ft wide, all 7 or 8 ft tall.

Single garage door sizes

A single door is 8, 9 or 10 ft wide. Clopay names 8 × 7 and 9 × 7 as the most common, CHI says most single doors are 8 × 7, and 9 × 7 has the most listings at Home Depot. Garaga, a door maker, says most cars fit through an 8 ft door easily, and it recommends 9 or 10 ft for pickups.

Mirrors are why. Spec sheets lead with body width, but the mirrors are what hit the door track. A 2026 Ford F-150 is 79.9 in wide across the body, 83.6 in with its mirrors folded and 95.7 in with them out (Ford). An 8 ft door is 96 in.

Room left on each side of a single door

Honda doesn’t publish a US width with mirrors, so the CR-V figure is ADAC‘s measurement of the EU-spec CR-V (2,153 mm); its body is 73.5 in wide (Edmunds). F-150 widths are Ford’s. Room is the door width minus the vehicle width, split evenly between the two sides.

Real openings are often a little narrower than the door’s name. Weatherstripping and trim sit inside the jambs. In a builder’s worked example, they take about 2¼ in from a 9 ft door, leaving 105¾ in of clear width (Ask the Builder). Measure your own opening before you rely on the numbers above. Garage door width covers clear width and room per side in more detail.

An 8 ft door works for cars and small SUVs if you park straight. Choose 9 ft if someone drives a full-size pickup or SUV, or if you don’t want to fold mirrors every time. A 10 ft single is on Clopay’s standard list, but the only 10 × 7 at Home Depot is a roll-up door, so expect to order a sectional one through a dealer. More in single garage door sizes.

Double garage door sizes

The standard double door is 16 × 7 ft. Clopay says it fits two average sedans, crossovers or smaller SUVs, and that full-size trucks fit but take more care to park. Doubles also come narrower (12 and 14 ft) and wider: 18 ft is the usual step up, and 20 ft is the widest most makers list.

A 16 ft door is 192 in wide. Here is how much of that two vehicles leave, in total, for the gaps on both sides and between them:

Two cars or small SUVs fit a 16 ft door with about 7½ in per gap. Clopay says two full-size trucks still fit with more careful parking, but with mirrors out the numbers leave 0.6 in in total, so in practice both drivers fold their mirrors every time. For two trucks, an 18 ft door gives a little more room than two CR-Vs get in a 16 ft door.

16 × 8 is the tall double. Garaga says it is the double size its customers ask for most, but at US big-box stores 16 × 7 still has nearly twice the listings (Lowe’s: 51 vs 28).

Two singles or one double? Two single doors each open less often, so they last longer, and one still works if the other breaks. A double door needs only one opener and leaves more freedom to position the cars (Garaga). Two singles need a post between them. We found no maker’s figure for its width. Each door’s track needs 3¾ in of wall beside the opening, so the post must be at least 7½ in wide at the tracks and 9 in where torsion springs attach above the openings (Clopay). A wall-mounted opener on the post side needs 8½ in by itself. More in double garage door sizes.

Garage door height: 7 ft or 8 ft?

7 ft is the standard height for single and double doors (Clopay). 8 ft is the common upgrade, and Clopay suggests it for a larger SUV, a truck, or roof racks and bikes on top of the car. Clopay and CHI also build the heights in between, in 3-inch steps.

Heights from Honda, Chevrolet, Ford (F-150, Super Duty, Transit). Ranges cover the trims each maker lists. The tallest F-150 is the Raptor.

Every stock car, SUV and half-ton pickup above fits under a 7 ft door. The margin is what changes. Below about 3 in, an 8 ft door is the safer choice, for two reasons.

• The open door hangs lower than the header. When the door is up, its top section rides in the overhead track and can sit slightly below the top of the opening. We found no maker’s figure for how much. If you have less than 3 in to spare on paper, open the door and measure from the floor to its lowest edge.
• Roof loads add up fast. A Thule Motion 3 XL roof box rises 15 in above the crossbars (Thule). On a 66.5 in CR-V that leaves 2.5 in under a 7 ft opening for the crossbars and their feet. Measure the total before you drive in.

A taller door needs more room inside, too. Its track and opener reach about a foot deeper into the garage (see space around the opening), and a do-it-yourself opener may need a longer rail: Genie’s kit needs a rail extension for doors over 7 ft (Genie). More in garage door height.

Custom and oversized doors

If no standard size fits, makers build to order. Clopay builds some models in 2-inch width steps (8 ft 2 in, 8 ft 4 in and so on) and most in heights up to 16 ft (Clopay). Garaga builds doors 4 to 20 ft wide to the nearest inch, and 6 to 12 ft high.

RV doors are usually 10, 12 or 14 ft tall (Clopay, Amarr). Size one from the motorhome’s spec sheet, not its class. A Winnebago Adventurer 35F is 12 ft 1 in tall, so it misses a 12 ft door by an inch and needs a 14 ft one. A Minnie Winnie 31K is 11 ft tall and clears a 12 ft door by a foot.

Space a door needs around the opening

The door is the same size as the opening, but its tracks, springs and opener need room beside, above and behind it. Makers ask for slightly different amounts, so here are the ranges:

Sources: Clopay installation manual, Amarr, Wayne Dalton manual (125 in and 137 in with an opener), Chamberlain opener lengths (123 to 128 in and 135 to 142 in), Amarr (door height + 50 in with an opener), Raynor, LiftMaster 98022 manual.

How to measure for a garage door

1. Width (A). Measure the finished opening from jamb to jamb at the bottom, middle and top. Use the narrowest number.
2. Height (B). Measure from the floor to the underside of the header at both sides and the middle. Use the lowest number, since garage floors slope.
3. Side room (C). Measure from each side of the opening to the nearest wall or obstruction. You need at least 3 to 3¾ in.
4. Headroom (D). Measure from the top of the opening to the lowest thing above it: ceiling, beam, pipe, duct or light. Standard tracks need 10 to 13½ in, plus 2 to 3 in for an opener.
5. Backroom. Measure from the door wall straight back to the first obstruction.

Order the door at the opening size. Clopay’s install manual says the opening, minus the stop molding, is the “same size as door”, and Amarr says the opening “is the same size as your new garage door.” Some guides tell you to add an inch on each side. Don’t, or you will order a door wider than your opening.

If you are framing a new opening, the framed (rough) opening is bigger than the door: about 3 in wider and 1½ in taller, to leave room for the wood jambs and header (Angi). More in garage door rough opening.

Does building code set garage door sizes?

No. The International Residential Code doesn’t set a garage door size. The IRC rule on the door itself, section R609.4, is about wind: doors must be tested to ASTM E330 or ANSI/DASMA 108 and carry a label with their wind rating (DASMA). Your city, county or HOA can still have its own rules, so ask before you order a larger door.
