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: 2026-03-09 to 2026-06-21, 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.
