Each space type has its own solver with geometry, tolerances, and edge cases tuned for that specific problem.
Every face of your item is tested against the opening — straight, angled, tilted, and in full 3D rotation. We find the way through if one exists.
Width, height, and length checked simultaneously. If your hallway has a turn, we automatically route to our corner solver.
Full geometric sweep of 90-degree and 180-degree turns. When flat passage fails, we test single-axis tilt and compound tilt to find a solution.
Three-checkpoint analysis: door clearance, cab interior fit, and in-cab rotation. Supports passenger and freight elevator profiles.
Straight, winder, and spiral staircases — each solved with its own geometry. Pick your exact stair type in-chat and the solver re-runs with real tread, riser, and radius dimensions.
Trunk, back seat, truck bed, and cargo van — each modeled with access opening constraints, seat configurations, and interior geometry.
Once it's inside, does it actually work? We check activity clearances, door-swing conflicts, and try multiple arrangements to find the layout that leaves the room usable.
Moving pods, storage units, shipping containers, and boxes — each treated as its own 3D packing problem with stacking rules, loading order, and residual-space tracking.
The narrowest spot on the whole path is usually what decides it. Our tightest-blocker solver finds the single tightest clearance across every obstacle — so a radiator beside a doorway can't sneak past the check.
Most tools give you a yes or no. We give you the full picture.
Your item is checked in all 6 physical orientations — upright, on its side, on its back, and every other permutation. We never miss a way it could fit.
When standard orientations fail, we explore simultaneous pitch and yaw rotations — the kind of creative angling movers use in real life.
Real moves involve multiple obstacles. We solve "through the door AND down the hallway" as one connected problem, not two separate checks.
We model trim, baseboards, weatherstripping, handrails, radiators, and elevator tracks — with height-dependent obstacle profiles, not flat deductions.
Compression, disassembly, round shapes, and human limits — modeled, not ignored.
Mattresses, cushions, and cardboard boxes aren't rigid. We model per-category compression — a mattress can compress up to 15%, cushions up to 30% — and re-test when the rigid solve says "doesn't fit."
Say "I can take the legs off" and we split the item into pieces — tabletop, legs, frame — solving each one independently. You see which pieces fit and which don't.
Round tables, drums, and water heaters aren't boxes. We use circular cross-sections — a round table only needs its diameter to clear the opening, and sweeps corners as a circle, not a rectangle.
A 3mm clearance over 2 meters with a 50kg item is geometrically possible but physically impractical. We score difficulty by weight, path length, and angular precision — and tell you how many people you need.
Graduated verdicts, confidence ratings, and transparent assumptions — so you can trust the answer.
Five levels from "fits with room to spare" to "does not fit" — with exact clearance in inches and millimeters. You see precisely how much margin you have, not a vague thumbs up.
Every result includes a confidence level — from mathematically proven (your measurements, clear margin) down to uncertain (estimated dimensions, tight margin). You always know how much to trust the answer.
Every assumption is surfaced: "assumed 8ft ceiling", "item is rigid", "hallway unobstructed". Nothing hidden — you decide if the assumptions match your situation.
Context-aware tips like "tilting requires 2+ people", "watch for wall fixtures", or "professional movers recommended". Not just a fit result — guidance on how to execute.
Change dimensions, toggle seat configurations, or switch orientation constraints in real time. See how each change affects the verdict instantly — no re-typing needed.
Tilt angles, clearance per axis, tightest constraint identified. See the math behind the answer — every orientation tested, every margin computed.
At the fit boundary, we disclose a ±6mm real-world tolerance band alongside the geometric result. Borderline verdicts acknowledge tape-measure reality instead of pretending sub-millimeter precision matches the real world.
"What if the door was 34 inches?" keeps the prior solve in context and re-runs only the piece that changed. Item rechecks and space corrections are routed separately — no re-typing the whole question.
Just describe your move. We handle the rest.
Two proprietary AI models read every query. A fast pass extracts items, dimensions, and spaces; a second, more powerful pass peer-reviews anything ambiguous. Regex runs alongside as a safety net — so "Can my 84-inch couch fit through a 32-inch door?" parses exactly the way you'd expect.
Every AI dimension estimate we make is sampled. Once samples agree, they're promoted to canonical cached values via race-safe SQL — so the item catalog grows from real usage and repeat questions come back instantly.
Don't know the exact dimensions? Say "queen mattress" or "65-inch TV" and we pull standard dimensions from our ever-growing catalog — clearly labeled as estimated so you always know what came from you versus us.
Check multiple items at once. We run 50+ packing trials across 5 strategies — space-efficient, easy-access, grouped, balanced, and randomized — keeping the best layout. Stacking rules, loading order, and residual space analysis included.
Inches, feet, centimeters, millimeters — mix and match freely. We normalize everything internally and report results in your preferred unit.
New ways to check fit — reverse queries, browser extension, mathematical proofs, and intelligent alternatives.
Flip the question. Instead of 'does X fit in Y,' ask 'what fits in my 24-inch opening?' and get catalog-matched recommendations ranked by fit — with nominal sizes, allowance math, and proof tabs.
Check fit while you shop. Our browser extension scans retailer product pages, extracts dimensions automatically, and runs a fit check against your saved spaces — all without leaving the store's site.
Every verdict shows its work. See the exact formula, the substituted values, and the result for each step — from input dimensions through orientation testing to the final verdict.
When something doesn't fit, we don't just say no. Up to 5 actionable alternatives are generated automatically — smaller items, different paths, disassembly options, or creative orientations.
3 free fit checks + 1 visual proof to start. No credit card required.
