Will a 40 gallon bin (76x51x41 cm) fit in a space?
Expert analysis
A 40 gallon bin measuring 30 in × 20 in × 16 in fits in a space, with about 2 in to spare at the tightest point. The binding dimension is height: in its best-fitting orientation, the height is what comes closest to the limit, and it still clears. The persisted calculation steps support the reported tightest-point margin. One caveat: item is rigid and cannot be compressed, bent, or disassembled.
- Tightest clearance
- 0 in clear
- Result
- Every axis clears
It fits with clearance on every axis.
- Every axis clears the opening — height is the tightest.
- No tilting or compression needed.
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.

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.
