Key findings
Which items fit, in four lines.
- At a standard doorway, a couch / sofa was too large to clear it as-is in 92.9% of distinct checks (n=379) — narrower examples and wider doors did pass.
- A fridge was next: too large for a standard doorway in 76.9% of checks (n=13).
- Not everything is hard: a dresser fit cleanly in 86.4% of its checks (n=22).
- The tightest passing fits came down to millimetres, drawn from 125 published result pages.
The standouts
Some items rarely clear a standard door as-is.
Share of distinct door checks per item that came back too large to clear the doorway as-is, over 2026-03-09 to 2026-06-21. The remainder fit.
Least likely to fit
Highest failure-rate items.
| Item | Too large as-is | Checks |
|---|---|---|
| couch / sofa | 82.9% | n=533 |
| table | 72.2% | n=18 |
| standard 3-seat sofa (84"×35"×34") | 70.6% | n=17 |
| fridge | 70.6% | n=17 |
| box | 43.5% | n=23 |
| sectional | 28.6% | n=14 |
| mattress | 27.3% | n=11 |
| bed | 22.2% | n=18 |
Each distinct item × space × dimensions check counts once — not weighted by how often it was looked up. Items with at least ten such checks shown. The rate is the share that came back too large to fit as-is; the remainder fit. couch and sofa are counted together.
Most likely to fit
Highest success-rate items.
| Item | Fit cleanly | Checks |
|---|---|---|
| queen bed | 100% | n=17 |
| bookshelf | 100% | n=10 |
| large item | 100% | n=10 |
| dresser | 86.4% | n=22 |
| bed | 77.8% | n=18 |
| mattress | 72.7% | n=11 |
| sectional | 71.4% | n=14 |

The 12 closest passing fits among 125 published result pages. Each row is a single observed result, so it carries no sample size of its own.
Methodology
How we counted this.
Per-item fit rates are tallied from the solver result cache, one tally per distinct item-and-space query. The tightest-clearance list is drawn from published result pages.
- 01Window: 2026-03-09 to 2026-06-21
- 02Two sources, each with a caveat. Per-item rates come from query_result_cache, which has no account or session column, so internal QA lookups cannot be separated out and may be included, and each count is a distinct cached query rather than a unique person. The tightest-fit list comes from published result pages, which over-represents close calls people chose to publish.
- 03Dimensions: each check uses what the visitor entered. When an item is named without exact measurements, ItemFits fills in typical dimensions before solving (from a product catalog, a saved or web-search lookup, or a model estimate), so these outcomes reflect real-world queries against typical item sizes rather than lab-measured objects.
- 04In the 3033 checks that recorded how the item dimensions were obtained, 36.8% used measurements the visitor supplied. The rest used a size ItemFits resolved for the named item: 38.4% from a known-product match, 4.1% from a web or model estimate, and 20.7% from a default or unspecified source.
The honesty contract
What we excluded.
Every published figure carries its sample size. Anything below the threshold is suppressed, never shown as zero.
- !Items that appear fewer than ten times are suppressed rather than shown. Dismissed and generic non-item labels are dropped, and malformed parse artifacts are removed from the clearance list.
- !Items are modeled as rigid rectangular boxes (their width by depth by height envelope) and tested across orientations. We do not model irregular shapes, protruding handles or legs, or flexible materials, except where an explicit compression or take-apart allowance applies.

Frequently asked
Questions we keep getting.
Where do the per-item rates come from?
They are tallied from the solver result cache. That cache has no account or session column, so unlike the headline studies it cannot have internal QA traffic removed, and each count is a distinct cached query rather than a unique person. Treat these as directional.
01What does tightest real fit mean?
It is the smallest passing clearance recorded on a published result page. A small margin means the item only just made it. These are individual results, so each carries no sample size of its own; the pool they were drawn from is stated under the table.
02Why do couch and sofa both appear?
People type items in their own words. Where the same concept is entered different ways, each label is shown as entered rather than merged, so you can see the raw signal.
