How to Measure Your Car Boot
Five measurements, about five minutes. This works for any vehicle — listed in our database or not — and makes the fit calculator far more accurate.
Measure the narrowest usable point
Don't measure the widest gap and assume that's what you have to work with — wheel arches, trim, hinges and tail-light surrounds often narrow the real opening. Don't count flexible trim or rubber seals as guaranteed clearance; they help, but measure without relying on them.
The Five Measurements
1. Boot Opening Width
Stand at the back of the car with the tailgate/boot open. Measure the narrowest horizontal gap you'd have to pass an item through — usually between the tail-light surrounds or trim, not the widest point of the bumper.
2. Boot Opening Height
Measure from the load floor (or bumper lip) straight up to the top edge of the opening — the tailgate frame or hatch seal, whichever is lower.
3. Cargo Depth (seats up & folded)
From the closed boot lip, measure straight along the load floor to the back of the rear seats (seats up), and again to the front seatbacks with the rear seats folded flat.
4. Narrowest Width (Wheel Arches)
Many boots narrow at the wheel arch bulges. Find the tightest horizontal gap along the whole cargo area — not just at the opening — since this is the true limit for a rigid item.
5. Maximum Cargo Height
From the load floor straight up to the roof lining or parcel shelf/cargo cover mechanism — whichever is lower. Remove a parcel shelf if it's removable and you don't need it.

Measuring Your Car — FAQ
What should I measure first?+
Boot opening width and height first — this is what most often surprises people, since it's usually narrower than the cargo space behind it.
Do I need special tools?+
A regular tape measure is enough. A folding carpenter's rule can help in awkward angles.
Should I measure to the trim or the metal?+
Measure to whatever will actually contact your item — usually the trim/plastic surround, not the bare metal behind it, since that's your real usable space.
