Standard garage door sizes
Doors come in set widths and heights. The right one depends on what you park, and the room around the opening.

The short answer
Standard garage door sizes, as Clopay lists them, are widths of 8, 9, 10, 12, 14, 15, 15½, 16 and 18 feet, and heights from 6 to 8 feet in 3-inch steps, except 7 ft 3 in.
Single doors are usually 8 to 10 feet wide and double doors 16 or 18 feet. Taller and custom sizes are made too. Measure the finished opening, because the door is ordered to match it.
Key takeaways
8, 9, 10, 12, 14, 15, 15½, 16 and 18 ft (Clopay).
6 to 8 ft in 3-inch steps, except 7 ft 3 in (Clopay).
8, 9 or 10 ft wide.
16 or 18 ft wide.
Clopay says the finished opening should match the door size.
How do I find my garage door size?
Measure the opening, not the door panels.
Between the finished jambs, at the top, middle and bottom. Use the smallest.
Floor to the underside of the header, at both sides.
Top of the opening to the lowest ceiling obstruction. Standard tracks need 10 to 12 in (Clopay).
Each side of the opening to the wall: 3¾ in for standard springs (Clopay).
The door height plus 18 in, plus more for the opener (Clopay).
Which standard size fits which use?
The sizes are the maker’s. The fit notes are HyreGarage analysis using Ford’s published F-150 widths.
| Size | Fits |
|---|---|
| 8 ft wide | Compact and mid-size cars. A full-size pickup with mirrors out does not fit: Ford lists the 2026 F-150 at 95.7 in over standard mirrors, against a 96 in door. |
| 9 ft wide | The practical single door for trucks and large SUVs. |
| 10 ft wide | Trucks with tow mirrors, trailers, or a tight turn into the garage. |
| 16 ft wide | The common double door for two cars. |
| 18 ft wide | Two large vehicles, with more room to open car doors. |
| 7 ft high | Cars and most SUVs. |
| 8 ft high | Lifted trucks, roof racks, vans. |

One double door or two singles?
A 16 ft double door is one door, one opener and no center post, which makes parking easier. Two singles cost more in parts and need a post between them.
They also keep one bay closed when the other is open, and one failure leaves you a working door. See two car garage door dimensions.
What to ask before you sign
Width and height, finished.
The full ten-point checklist is on choosing a garage door company.
Where this goes wrong
Doors overlap the opening slightly. Measure the opening.
Mirrors decide fit, not the body width.
A taller door needs room above it for the track and opener.

Primary-source research, data analysis and fact checking
We are not a garage door company. We read the agency file, the code record, the standards document or the public register ourselves, compute the figure from it, and publish it with the source and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. Our own company records cover ten states; nothing national is ever derived from them.
- 10
- states our own company records cover — and the limit of any claim made from them
- 3,901
- garage door companies in the store
- 457
- license records verified against a state board
- 0
- national claims made from a ten-state store
How this desk works
- Primary sources only. Injury counts come from CPSC. Housing counts come from the Census file, not from a summary of it. Code history comes from the building commission that adopted the code. We do not cite an article that cites a source; we retrieve the source and do the arithmetic ourselves.
- Every figure carries its retrieval date. Registers change, datasets are revised and codes are amended. A number without the date it was read cannot be checked, so every study states one.
- Fact, calculation and analysis are labeled apart. A quote is a quote, a HyreGarage computation says so, and an interpretation says “HyreGarage analysis”. Presenting our reading of a dataset as something the agency stated would be the easiest way to lose the only thing this desk is for.
- Limitations go above the fold. If a figure is an upper bound, a bracket, or an association rather than a cause, that is said before the figure is quoted rather than in a footnote underneath it.
- No DIY instructions for spring, cable or track work. Those components hold enough stored energy to cause serious injury, and CPSC records the consequences. We describe what has failed and what a competent repair involves; we do not tell you how to do it.
Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
Sources & retrieval dates
Information on this page is general and varies with the door, the opener, local code and circumstance. It is not safety, insurance or legal advice.
Springs and cables hold dangerous stored energy: adjusting or replacing them is work for a trained technician. HyreGarage does not repair, replace or install garage doors.
This page explains the work so you can judge a quote and a company.
