Widthmm
Width is the car's side-to-side body measurement, often excluding mirrors. It matters for lanes, garages and tight charging bays. It matters only when it survives real use: people inside, bags in the boot, cables stored somewhere, doors opening wide enough and the loaded car staying within legal weight.
How to compare it
Compare width with mirror width if available, because the real squeeze in car parks is usually mirror-to-mirror.
- Check the number against your garage, child seats, luggage and parking.
- Look for shape and access, not just litres or millimetres.
- Payload can be more important than volume.
What changes it
Practicality changes when the same number meets real objects: child seats, boxes, roof racks, kerbs, charging cables, passengers and payload limits.
- Shape and access can beat a larger raw volume number.
- Payload includes people, luggage and accessories.
- Exterior size affects parking even when cabin space is good.
Common trap
A car that feels fine on a spec sheet can be annoying if your home charger sits beside a narrow driveway or wall.
- A bigger number can still be awkward if the shape is poor.
- Accessories and passengers count against payload.
Width: the packaging view
Dimensions become useful only when you connect them to doors, boot shape, payload and your parking reality.
