How to use this calculator
Include cornices, feet, knobs and any non-removable trim. Compare the assembled dimensions with the clear opening. Enable other orientations only when the cabinet can safely be tipped.
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
A 100 × 180 × 45 cm cabinet through a 70 × 205 cm opening clears upright side first. With 1 cm per edge, remaining width is 23 cm and height is 23 cm.
Before you move
A cabinet can clear the door but still lack room to stand up inside the room. This tool does not calculate the lifting arc. Secure or remove loose shelves before handling.
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.
