Expert analysis

A sofa measuring 3 ft 2 in × 3 ft 2 in × 6 ft 11 in does not fit in a space, but it's about 6.5 in too large at the tightest point. The binding dimension is width: that is the axis where the sofa 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.

How we verified this

Binding axis: Width
Tightest clearance: 6.5 in over
Result: Width does not clear

−6.5 in over

· ON THE WIDTH AXIS

It exceeds the opening at the tightest point.

The width axis runs out of room.
A 1.5 in handling allowance is already subtracted.

AAxis inequality · opening width✕ FAIL

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

↓ SUBSTITUTE

38 \;\overset{?}{\le}\; 31.5\quad(\text{opening width})

↓ EVALUATE

38\,\text{in} \;>\; 31.5\,\text{in} \;\Longrightarrow\; \Delta = {-6.5}\,\text{in}

Plain English: Along the opening width, the item is 38 in and the space allows 31.5 in — over by 6.5 in.

BAxis inequality · opening height✓ PASS

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

↓ SUBSTITUTE

38 \;\overset{?}{\le}\; 51.5\quad(\text{opening height})

↓ EVALUATE

38\,\text{in} \;\le\; 51.5\,\text{in} \;\Longrightarrow\; \Delta = {+13.5}\,\text{in}

Plain English: Along the opening height, the item is 38 in and the space allows 51.5 in — 13.5 in to spare.

CDiagonal clearance · Pythagorean✓ PASS

\sqrt{a^2 + b^2} \;\le\; \sqrt{a_{\text{sp}}^2 + b_{\text{sp}}^2}

↓ SUBSTITUTE

\sqrt{38^2 + 38^2} \;\overset{?}{\le}\; \sqrt{31.5^2 + 51.5^2}

↓ EVALUATE

53.7\,\text{in} \;\le\; 60.4\,\text{in} \;\Longrightarrow\; \Delta = {+6.7}\,\text{in}

Plain English: Tilted corner-to-corner the face spans 53.7 in, inside the opening's 60.4 in diagonal — but a tilt only buys diagonal room, it can't widen the throat.

D3D space diagonal✕ FAIL

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

↓ SUBSTITUTE

\sqrt{38^2 + 38^2 + 83^2}

↓ EVALUATE

98.9\,\text{in} \;>\; 60.4\,\text{in} \;\Longrightarrow\; \Delta = {-38.5}\,\text{in}

Plain English: Corner to corner the item reaches 98.9 in — keep that swing room in mind for the turn after.

EMinimum required space · opening width✕ FAIL

d_{\text{req}} = d_{\text{item}} + t

↓ SUBSTITUTE

38 + 1.5 = 39.5

Plain English: Smallest space on the limiting axis that would admit this item (with handling tolerance).

FLargest item that fits · opening width✕ FAIL

d_{\max} = d_{\text{space}} - t

↓ SUBSTITUTE

31.5 - 1.5 = 30

Plain English: Largest item dimension this space admits on the limiting axis (after handling tolerance).

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.
