The studies
Real-world fit data.
What this is
Data from real fit checks.
ItemFits runs thousands of fit checks. These studies publish what that corpus shows about how big things move through tight spaces.
- 01Aggregated from actual solver verdicts, not surveys or estimates.
- 02Window: 2026-07-25 to 2026-09-09, refreshed on each snapshot.
How we keep it honest
Every number shows its N.
We would rather show less than overstate. A figure without enough data behind it is suppressed, never padded to look complete.
- !Internal test accounts and bot traffic are removed before counting.
- !Below-threshold rates are shown as not enough data yet, never as zero.
Frequently asked
Questions we keep getting.
Where does this data come from?
Every figure is aggregated from real fit checks run on ItemFits, after internal test accounts and bot traffic are removed. Each published number carries its sample size.
01How often is it updated?
These studies cover the window 2026-07-25 to 2026-09-09. They refresh when we re-run the snapshot and redeploy, not continuously.
02Can I cite these numbers?
Yes. Each study is published as a citable dataset with its method and sample sizes stated. Please link back to the study page so readers can see the methodology.
