Will a King bed frame (80"×85"×14") (203x191x36 cm) Fit Through a 91 cm Door?

−3 ft 8 in over

· ON THE WIDTH AXIS

It exceeds the opening at the tightest point.

Your king bed frame (80"×85"×14") will not clear the space — but only just — it is a hair over the limit at the tightest point. The passage is the limiting constraint.

Handling: The item exceeds the space in every orientation — standard entry won't work.

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.
