How to use this calculator
Measure the narrowest loading opening and an unobstructed rectangular space inside the boot. Use actual measurements, not cargo volume in litres. Include the item’s packaging.
Formula and assumptions
Minimum of all tested clearances
Subtract the item dimension and twice the allowance from each matching opening or interior dimension. An orientation clears only when every remainder is zero or positive. Choose the orientation with the largest minimum remainder.
A door-only result checks a cross section, not the travel length. Interior tools also check item depth. For a door plus interior, the same orientation must satisfy every dimension.
Worked example
An 80 × 50 × 40 cm box clears a 95 × 65 cm opening into a 100 × 70 × 110 cm cargo space upright front first. With 1 cm per edge, minimum remaining clearance is 13 cm at the opening height.
Before you move
Wheel arches, sloped glass and seats often make cargo spaces irregular. The box model cannot guarantee hatch closure or safe securing. Keep visibility and restraint requirements in mind.
A fit estimate is not a route simulation. It does not account for corners, stairs, lifting room, weight limits or diagonal maneuvers.
Frequently asked questions
Can I squeeze it through diagonally?
This tool only tests axis-aligned straight positions. A failed check does not prove a diagonal maneuver is impossible. Ask your mover to assess the actual item and route.
What does clearance per edge mean?
A 1 cm allowance removes 2 cm from each opening dimension: one allowance at each edge. The displayed remainder is extra space after that allowance.
Are these dimensions product specifications?
No. Default dimensions are illustrative examples. Measure the actual item, including fixed handles, feet and packaging.
Rectangular straight-pass estimates only. Check the entire route and confirm difficult moves with a professional.
