Expert Analysis
✕ Does not fit — 12" too large
[why-details]
> Why it doesn't fit
The item exceeds the opening in every orientation — no rotation or tilt resolves this.
Tightest point: Item vs Opening (width axis)
Remaining clearance: 12" (28.6%)

> How to make it work
The item exceeds the space in every orientation — standard entry won't work. Consider these alternatives:
- Disassemble the item if possible
- Check for wider doors or windows
- Consider professional movers with pivot techniques

Safety margin: Comfortable
Operational expectation: Standard handling — no special equipment or technique needed.

If the hallway has an L-shaped turn (assuming equal corridor widths), the item can also navigate the corner — 2" clearance.

What we used · Low Confidence
Opening: 42"W × 72"H
Item: mattress — smallest cross-section 13" (estimated)
*Rotation required: reoriented*
Assumptions
- Item is rigid and cannot be compressed, bent, or disassembled
- Space has perfectly square corners and flat surfaces
- No obstructions (light fixtures, handrails, trim, furniture) in the path
- Path from entry to destination is straight with no turns
- Floor is level with no steps or thresholds
All orientations tested (6 orientations)
| | Orientation | Width | Height | Note |
|---|------------|-------|--------|------|
| ✗ | 1524mm across, 330mm vertical | -18" | 59" | too_wide |
| ✗ | 1524mm across, 2032mm vertical | -18" | -8" | too_wide |
| ✓ | 330mm across, 1524mm vertical | 29" | 12" | |
| ✗ | 330mm across, 2032mm vertical | 29" | -8" | too_tall |
| ✗ | 2032mm across, 1524mm vertical | -38" | 12" | too_wide |
| ✗ | 2032mm across, 330mm vertical | -38" | 59" | too_wide |
Step-by-step proof (best: 330mm across, 1524mm vertical)
1. Width: 13" item ≤ 42" opening → ✓ (29" clearance)
2. Height: 60" item ≤ 72" opening → ✓ (12" clearance)
Limiting: hallway_height at 12"
