Will a bag (51x66x41 cm) fit in a container?
Expert analysis
A bag measuring 20 in × 26 in × 16 in does not fit in a container, but it's about 3 in too large at the tightest point. The binding dimension is depth: that is the axis where the bag runs out of room. The persisted calculation steps support the reported tightest-point margin. One caveat: item is rigid and cannot be compressed, bent, or disassembled.

- Depth does not clear
It exceeds the opening at the tightest point.
- The depth axis runs out of room.
- A <1 in handling allowance is already subtracted.

| 660×406×508mm (On its side) | — | 6.5 in | 7 in | ✕ | Too deep |
| 406×508×660mm (On its side) | — | 16.5 in | 1 in | ✕ | Too deep |

How the container-fit check works
A container is a fully 3D box — length, width, AND height must accept the item simultaneously; corner reachability is a soft second constraint.
- Treat the container as a 3D box and generate the item’s 6 dimension permutations (3 axes × 2 flips).
- For each permutation, apply the constraint: item ≤ container on length, width, and height simultaneously.
- Check reachability — items longer than arm’s reach can’t be loaded all the way into the back corners.
- Subtract 1.5 in handling clearance on each axis for the mover’s grip plus pivot room.
- Verdict ladder (verdict-tiers.js, shared with door): FITS ≥ 2 in; FITS_TIGHT 0.5–2 in; FITS_VERY_TIGHT 0–0.5 in; DOESN'T_FIT below.
Interior dimensions use the published spec; door rails, ribs, and floor lashings can shave 1–2 in off the usable corners.

Space geometry
- Container floor is flat and rectangular

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.
