Boot dimension fit checker
For anyone with a tape measure: enter your boot and opening measurements and your item’s size. No vehicle database needed — it works for every car, van or SUV.
Your car
Car not listed or different generation? — it takes about two minutes.
Measure your own car (how to measure). Leave anything you can't measure blank — we'll tell you what's missing rather than guess.
Advanced: tapers and sloping tailgates
If the opening is narrower at the top, or the height is lower near a sloping tailgate, enter the smaller figures here. The conservative check uses the smaller of each pair.

Your item
The six measurements
The basic check needs five numbers from your car (A–E). Measurement F unlocks the seats-folded comparison. Leave anything blank that you can’t measure — the result will tell you exactly what’s missing instead of guessing.
| Measurement | Where to measure | Why it matters |
|---|---|---|
| A. Floor length | Rear seatback to the inside of the closed tailgate, along the floor | Limits the longest dimension you can lay flat |
| B. Narrowest width | Between the wheel arches (or other intrusions) | A rigid box can’t use the extra width beside the arches |
| C. Usable height | Floor to parcel shelf, load cover or the lowest roof/hatch point | Limits tall items and boxes on their side |
| D. Opening width | The narrowest clear gap of the boot opening | The item has to get through here first |
| E. Opening height | Top of the loading lip to the lowest point of the opening | Often the real limit on hatchbacks and saloons |
| F. Seats-folded length | Back of the front seats to the closed tailgate | Long items usually need the seats folded |
Basic and advanced mode
The basic check treats the cargo space and opening as rectangles. Open Advanced: tapers and sloping tailgates to enter the opening width at the top (many openings narrow towards the roof) and the height near the tailgate. The conservative check then uses the smaller figure of each pair, and tells you it has done so.
Reading the result
- Likely fits — fits the entered space and passes the opening in at least one orientation, with your clearance allowance.
- Might fit — very tight, needs an angled placement or turning after loading, or the opening hasn’t been measured.
- No fit found in the tested orientations — every straight orientation is blocked; we say which measurement blocks it.
- More measurements needed — we list the exact measurements to take.
