Garage door widths in UK homes vary between standard sizes that correspond to the typical garage construction widths used over the past century of residential building. Knowing the standard sizes helps homeowners identify a replacement door and understand whether a made-to-measure option is needed.

Standard Single Garage Door Widths

The most common standard widths for single garage doors in the UK are 7 feet (approximately 2.134 metres), 7 feet 6 inches (approximately 2.286 metres), and 8 feet (approximately 2.438 metres). These correspond to the brick course widths used in typical 1930s to 1980s residential garage construction. Many replacement doors are manufactured to these standard widths and represent the best value and fastest availability. Newer garages and those built with concrete lintels may have slightly different opening widths.

Standard Double Garage Door Widths

Double garage doors span a single opening that accommodates two vehicles side by side. Standard widths range from 14 feet (approximately 4.267 metres) to 16 feet (approximately 4.877 metres), with 15 feet (approximately 4.572 metres) being common. Some double openings are fitted with two single doors rather than one wide door; this is often the better solution as it allows one vehicle to be accessed without opening the full width.

Measuring Your Opening

To determine the correct door width for a replacement, measure the clear opening width at its widest point between the finished brick or masonry jambs. For an up-and-over door, the door panel width is typically 25 to 50mm less than the opening width to allow for the frame. When measuring, also record the opening height, the available headroom above the lintel, and the available sideroom on each side for the track brackets.

Made-to-Measure Doors

Non-standard opening widths, common in converted garages, barn conversions, and older properties with unusual proportions, require made-to-measure doors. Most major garage door manufacturers supply made-to-measure options at a modest premium over standard sizes. The lead time for made-to-measure doors is typically two to four weeks longer than standard stock items.

Summary

Standard UK single garage door widths are 2.1m, 2.3m, and 2.4m (7ft, 7ft 6in, 8ft). Double garage openings range from 4.3m to 4.9m. Measure the clear opening width at the narrowest point. Made-to-measure doors are available for non-standard openings at a modest premium with a longer lead time. Measure width, height, headroom, and sideroom before ordering any replacement door.
