Will a laboratory cabinet (91x56x198 cm) fit through an 81 cm door?
Expert analysis
A laboratory cabinet measuring 36 in × 22 in × 78 in does not fit through a door, with about 10 in to spare at the tightest point. The binding dimension is width: that is the axis where the laboratory cabinet runs out of room.
It exceeds the opening at the tightest point.
- The width axis runs out of room.

How the door-passage check works
A door is a 2D opening — width and height matter; depth (path length through the doorway) doesn’t.
- Generate all 6 dimension permutations of the item (3 axes × 2 flips).
- For each permutation, apply the door constraint: item_width ≤ door_width AND item_height ≤ door_height.
- Subtract 1.5 in handling clearance from each axis to leave room for human movement.
- Pick the permutation with the largest minimum-axis margin — that’s the orientation a mover would choose.
- Verdict ladder (verdict-tiers.js): FITS if margin ≥ 2 in; FITS_TIGHT if 0.5–2 in; FITS_VERY_TIGHT if 0–0.5 in; DOESN'T_FIT below.
Tolerance ±¼ in (6 mm) is applied implicitly (band promotion to FITS_VERY_TIGHT) — see the note below the orientation matrix.
Dimensions

- STANDARDDoor width32"
- STANDARDDoor height80" (2032mm)
- MEASUREDApplied 38mm practical clearance for handling
Space geometry
- Square corners and a flat floor
- No trim, fixtures, or hardware protruding into the opening
- Door swings fully open (90°+) and stays open during passage
Handling
- ±¼ in tape-measure tolerance applied
- 1.5 in handling clearance subtracted from raw margins before the verdict
- Item treated as rigid — cannot compress, bend, or disassemble.
