Garage Door Sizes Guide
Most residential garage doors are described by the framed opening width first and height second. Common examples include 8' × 7' or 9' × 7' single doors and 16' × 7' double doors, but Langley homes, townhomes, detached garages and workshops use many other dimensions.
Opening width and height are only the starting point. A correct plan also checks sideroom, headroom, backroom, ceiling obstructions, finished floor level, framing, track configuration, spring system and opener space before the door is ordered.

Vehicles and ceiling clearance
Record width first, then height
A 9' × 7' door is nine feet wide and seven feet high. Measure the finished opening, not only the existing door sections.
Residential sizing starting points
Common garage door sizes found around Langley
Use these as planning references only. The final door size must match the actual opening, track, spring and opener arrangement.
Common single door
9' × 7'A widely used single-car size with more parking clearance than an eight-foot opening.
Popular single-car sizeWider single door
10' × 7' or 10' × 8'Useful for trucks, wider vehicles, storage access or an easier turning approach.
Extra width or heightCompact double door
12'–14' wideFound on some older or space-limited garages. Two vehicles may fit, but parking can feel restrictive.

16' × 7'A common two-car residential size. Eight-foot height and wider versions are also available.

Measurement overview
Measure the opening, then the space around it
The framed width and height usually determine the nominal door size. The track, springs and opener need clear space inside the garage.
Measure the finished opening at more than one point. Older openings may not be perfectly square or level.

Opening height
Six measurements to record
Garage door measuring sequence
- Opening width: measure between finished jambs at the top, middle and bottom.
- Opening height: measure from finished floor to the underside of the header at the left, centre and right.
- Sideroom: measure both sides to the closest wall, framing or obstruction.
- Headroom: measure above the opening to the ceiling, joist, beam, duct or first obstruction.
- Backroom: measure from the opening toward the rear wall or first ceiling obstruction.
- Condition: note floor slope, gaps, uneven framing, rot, damage or earlier alterations.
Initial measurements help with planning. Final ordering measurements should be confirmed for the selected door and hardware system.

Common clearance figures are preliminary only.
Manufacturer guides often use about 3¾ inches of sideroom per side, 10–12 inches of headroom for common spring layouts and backroom equal to door height plus about 18 inches before additional opener allowance. Low-headroom and special-track systems can differ.
Layout affects daily use
One double door or two single doors?
The structure often determines the answer. When both layouts are possible, compare parking, weather exposure, exterior appearance and future service needs.
Wider shared opening
A double door removes the centre post and can make angled entry easier, but it opens a larger portion of the garage at once.
Review installation planningSeparate vehicle bays
Two doors provide separate access, but the centre pier reduces manoeuvring room and each bay needs separate track and opener planning.
Compare opener optionsChanging the opening
Widening, raising, combining or splitting openings can affect headers, framing, cladding, electrical work and permits.
Discuss a non-standard opening
The vehicle is not the only measurement
What else determines the right size?
A vehicle can pass through an opening and still be difficult to park, unload or fit beneath the open door and tracks.
Vehicle width and mirrors
Measure the widest point and allow practical steering clearance on both sides.
Vehicle height
Include roof racks, cargo boxes, bikes, canopies and antennas.
Driveway approach
Narrow, sloped, curved, rear-lane or shared driveways may need more entry width.
Ceiling storage
Open doors, tracks and opener rails can conflict with racks, lifts, lighting and ducts.
Door weight
Insulation, windows, overlays, material and size affect springs, tracks and opener compatibility.
Future use
Consider vehicle changes, workshop equipment, accessibility and EV charging position.
Langley property reality
Garage measurements vary across Langley housing types
Langley includes newer townhomes and rear-lane garages, established detached homes, custom properties, rural acreages, accessory buildings and workshops. The same nominal door size can need a different track, spring or opener layout.
Willoughby and Willowbrook projects may involve compact garages, strata standards and storage competing for ceiling space. Walnut Grove and Murrayville replacements can involve established framing. Fort Langley and Brookswood properties may have custom or renovated openings, while Aldergrove and rural garages may need taller doors for trucks or equipment.
For strata properties: confirm approved dimensions, panel design, colour, windows and exterior hardware before ordering.
For structural alterations: changing the opening, header or framing can trigger permit and construction requirements. Confirm the scope with the relevant authority before work begins.
Do not measure around an unstable door.
If the current door is crooked, off-track or supported by loose cables, keep clear and arrange repair first.
Choose the correct project path
Are you measuring for replacement, installation or repair?
The opening will remain
Confirm the framed opening and clearances instead of assuming the existing door label or section width is accurate.
Review garage door replacementThe garage or opening is changing
Coordinate framing, finished floor, tracks, springs, electrical supply, opener mounting and ceiling services.
Review installation cost factorsThe door binds or leaves gaps
Tracks, seals, floor level, framing, cables or balance may be the real issue rather than the nominal size.

Garage door sizes FAQ
Questions Langley homeowners ask
These answers cover common dimensions, opening measurements, headroom, backroom, double-door layouts and custom sizes.
What are the most common residential garage door sizes?
Common single doors are 8 or 9 feet wide by 7 feet high. A common double door is 16 feet wide by 7 feet high. Eight-foot heights and widths from roughly 8 to 10 feet for single doors or 12 to 18 feet for double doors are also available.
Is the garage door size the same as the framed opening?
For many standard sectional residential doors, the nominal door size matches the finished opening width and height. The jambs, header, floor and clearances still need to suit the selected door and track system.
What does a 9' × 7' garage door measurement mean?
Garage door dimensions are normally listed width first and height second. A 9' × 7' door is nine feet wide and seven feet high.
How much headroom is needed?
Requirements vary by spring system, track and opener. Common manufacturer guidance may start around 10 inches for some extension-spring layouts and 12 inches for standard torsion layouts. Low-headroom options may be available.
How much backroom is needed?
A common preliminary figure is the door height plus about 18 inches for the door and tracks. An opener can require additional room, and ceiling obstructions must be considered.
Should I choose one double door or two single doors?
A double door provides a wider uninterrupted entry. Two single doors create separate bays. The structure, centre pier, driveway approach and opener layout usually determine the practical option.
Can I order a custom garage door size?
Many manufacturers offer sizes beyond common dimensions, but availability depends on the product, construction, section layout, windows, tracks and spring system.
What should I send with an estimate request?
Send width, height, sideroom, headroom, backroom, neighbourhood, property type, project goal, vehicle requirements and clear exterior and interior photos.
Send the opening measurements before ordering the door
Include width, height, sideroom, headroom, backroom, property type, vehicle needs, project goal and photos. Final dimensions can then be checked against the proposed door, track, spring and opener system.
