Will a king mattress (193x203x25 cm) fit in a room?
Expert analysis
A king mattress measuring 76 in × 80 in × 10 in fits in a room, with about 5 ft 4 in to spare at the tightest point. One caveat: 36" primary walkway minimum (ada-style guideline, not code).
- Tightest clearance
- 5 ft 4 in clear
- Result
- Every axis clears
It fits with clearance on every axis.
Your king mattress will fit in the room, with comfortable walkway space around it.
Handling: Position the item in the room using the orientation that maximizes walkway clearance.

How the room-fit check works
A room is a 2D footprint — width and depth matter for placement, plus the walkway gap left between the item and walls or other obstacles.
- Place the item footprint inside the room rectangle in the orientation it will be used.
- Compute walkway gaps from each item edge to every wall and to other obstacles in the room.
- Take the minimum walkway gap — that’s the daily-traffic clearance the room must support.
- Verdict ladder (getRoomVerdictTier): walkway <18 in DOESN'T_FIT; 18–24 VERY_TIGHT; 24–36 TIGHT; 36–48 FITS; ≥48 confident FITS.
Walkway thresholds use standard ergonomic minimums; a confident mover may negotiate gaps tighter than the recommended tier.
