Expert analysis

A sofa measuring 84 in × 36 in × 34 in fits in a space, with about 8 in to spare at the tightest point. That margin already subtracts a 1 in handling allowance, so it reflects a realistic load rather than a paper-thin theoretical fit. One caveat: item is rigid and cannot be compressed, bent, or disassembled.

· ON THE WIDTH AXIS

It fits with clearance on every axis.

Your sofa will fit through the hallway, with comfortable room to spare.

Handling: Orient the item so it is reoriented.

AAxis inequality · hallway width✓ PASS

d_{\text{item}} \;\le\; d_{\text{space}}

↓ SUBSTITUTE

34 \;\overset{?}{\le}\; 42\quad(\text{hallway width})

↓ EVALUATE

34\,\text{in} \;\le\; 42\,\text{in} \;\Longrightarrow\; \Delta = {+8}\,\text{in}

Plain English: Along the hallway width, the item is 34 in and the space allows 42 in — 8 in to spare.

BAxis inequality · hallway height✓ PASS

d_{\text{item}} \;\le\; d_{\text{space}}

↓ SUBSTITUTE

↓ EVALUATE

84\,\text{in} \;\le\; 96.1\,\text{in} \;\Longrightarrow\; \Delta = {+12}\,\text{in}

Plain English: Along the hallway height, the item is 84 in and the space allows 96.1 in — 12 in to spare.

C3D space diagonal✓ PASS

\mathcal{D}_{3D} = \sqrt{L^2 + W^2 + H^2}

↓ EVALUATE

97.5\,\text{in} \;\le\; 104.8\,\text{in} \;\Longrightarrow\; \Delta = {+7.3}\,\text{in}

Plain English: Corner to corner the item reaches 97.5 in — keep that swing room in mind for the turn after.

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.
