Key findings
What the data says, in five lines.
- More than half of all checks, 54.7%, ended in a does-not-fit verdict (n=3065 decided checks).
- Only 37.1% of items fit cleanly with no modification needed.
- A further 8.3% were tight-fit calls, decided by the last inch.
- The most common blocker across every kind of space was walkway, decisive in 386 checks.
- The next two blockers were width (224 checks) and height (167 checks).

Methodology
How we counted this.
Every solver verdict over the data window, from real fit checks run on itemfits.com.
- 01Window: 2026-03-09 to 2026-06-20
- 02Source: the fit_check_results corpus, which carries an account and session identity, so internal QA traffic is removed at the source. Verdict and binding-constraint counts only. Per-item labels are not stored on this table, so constraint mixes are reported in aggregate and by space type, never per item.
The honesty contract
What we excluded.
Every published figure carries its sample size. Anything below the threshold is suppressed, never shown as zero.
- !Internal test accounts, bot sessions, and indeterminate verdicts (clarify, unknown, needs more info) that never resolved to a fit decision.

Frequently asked
Questions we keep getting.
How many checks is this based on?
These figures aggregate 3754 fit checks decided over 2026-03-09 to 2026-06-20.
01Does this mean most furniture does not fit?
No. It means most checks people choose to run are close calls. People reach for a fit calculator exactly when the answer is not obvious, so the corpus skews toward tight and failing cases rather than easy ones.
02Are internal or test checks included?
No. Internal test accounts and bot sessions are removed at the source, and indeterminate verdicts that never resolved to a fit decision are excluded from the split.
