Door types and construction
What size are standard UK garage doors?
The standard reference opening used for UK garage door pricing is 2290mm wide by 2250mm high, sized for a single car. Common width options range from around 2135mm up to 2440mm for a single door, while double doors typically span 4800mm to 5490mm across a shared or twin opening.
Single garage sizes
A single garage opening in the UK typically falls somewhere between roughly 2135mm and 2440mm wide, with height usually around 2000mm to 2250mm. Because openings vary between properties — especially older housing stock built before standardised garage dimensions — most doors are made to measure rather than sold in one fixed size.
Double garage and non-standard openings
Double garages are typically 4800mm to 5490mm wide, either as a single wide door on retractable gear or as two separate single doors side by side. Bespoke or oversized openings, common on converted barns or larger detached properties, are handled as made-to-measure orders and generally carry a longer lead time.
| Opening type | Typical width | Typical height |
|---|---|---|
| Single garage (narrow) | 2135mm | 2000–2150mm |
| Single garage (reference) | 2290mm | 2250mm |
| Single garage (wide) | 2440mm | 2150–2250mm |
| Double garage | 4800–5490mm | 2000–2250mm |
Figures are typical ranges, not a fixed standard — always measure your actual opening before ordering.
Questions people ask
- Why is 2290mm x 2250mm used as a reference size?
- It represents a common single-garage opening and gives a consistent basis for comparing installed prices across door types, since a bare price with no stated opening size cannot be compared fairly between quotes.
- What if my garage opening is not a standard size?
- Most UK garage doors, particularly sectional and roller types, are made to measure rather than sold in fixed sizes, so a non-standard opening is normal and simply needs accurate measurements taken during a survey.
- How do I measure my garage door opening?
- Measure the width at three points (top, middle, bottom) and the height at both sides, plus the depth of the structural opening and any headroom above it — an installer's survey will confirm exact figures before you order.
