How the garage-fit calculation works

The calculator is designed to separate a simple physical fit from a more practical everyday fit. It uses the measurements you enter and does not attempt to infer dimensions that are missing.

Entrance checked separately

Mirror width and vehicle height are compared with the narrowest clear door opening.

Internal obstructions included

Shelving, pillars and stored items can be subtracted from usable width and depth.

No hidden guarantee

A positive result is a planning estimate, not a promise that parking will be easy or damage-free.

1. Entrance-width clearance

The entrance calculation subtracts the selected vehicle width from the clear garage-door opening. If “fold mirrors” is selected, the folded-mirror width is used. Otherwise, mirror-to-mirror width is required. The calculator deliberately does not substitute body width when mirror width is unknown.

2. Entrance-height clearance

The vehicle height plus any roof-bar, roof-box or other entered addition is subtracted from the lowest usable opening height. Users should include fixed obstructions such as door mechanisms, beams and pipes in the measurement they enter.

3. Usable internal width

Left- and right-side obstructions are removed from the internal garage width. The remaining width is compared with the vehicle body width. The headline side-clearance figure assumes the vehicle is centred; real-world parking may be intentionally offset to create more driver-door room.

4. Usable internal depth

Front and rear obstructions are removed from the measured internal depth before vehicle length is subtracted. The remaining figure is total front-plus-rear clearance rather than a guaranteed amount at either end.

5. Comfortable, tight and no-fit indications

The status bands are deliberately conservative planning cues rather than engineering standards. A vehicle is flagged as not physically fitting if any critical dimension exceeds the corresponding available space. Small positive clearances are marked as tight because alignment, irregular walls, door hardware and access requirements can matter more than the raw number.

Vehicle reference data

The database uses manufacturer or official references where practical and independent dimensional references for broader model coverage. Each entry identifies its source. Where a mirror width is not sufficiently supported, the field remains blank and the user must enter an exact value.

Corrections

If you find a vehicle reference that appears incorrect or out of date, please send the model, generation and source information to contact@airbornemedia.co.uk. We would rather leave a value blank than fill it with an unsupported estimate.

Important: measure the actual garage and confirm the exact vehicle before purchase, construction or parking. Vehicle dimensions can change with model year, trim, wheels, mirrors and accessories.
