Which plate fits your boots?
Plate sizes are wheelbase in millimetres, measured axle to axle, unless a chart lists its own numbering (Mirage, Snow White, Rollerskatesitalia). Boot sizes for Edea and Risport are the printed boot size; Belati boots use European sizes; Riedell and Harlick boots use US sizes.

Already have a plate?
Pick a plate and size to see which boots the charts pair it with.
Results are grouped by mount: Medium is the chart fit for that boot, Short is one plate size under the chart fit (a shorter mount), and Long is one plate size over it (a longer mount). When a shorter option is shown, it is the recommended one.

About these charts
Data: Roll & Ice and Edea fitment charts, provided by Brock Curtice, October 2026. "Steel frames" means the standard non-titanium version of a plate, not an ice blade. Where two charts give different sizes for the same boot, this checker shows the smaller one and says so; that matches how the shop actually mounts plates (a 170 plate on a 280 boot, for example). Four charts that list sizes in inches turned out to be ice blade lengths rather than plates, so they are not used here. One shared chart row (Variant, Mariner Cup, Mistral, Saturno, Spin, Dance) pairs its frames with boots one step differently for Edea than for Risport; Edea's own chart and Roll-Line's master size-match chart both use the earlier pairing, so the checker follows the Edea pairing for Edea boots and says so on the affected rows. Rollerskatesitalia plates follow the standard Roll-Line sizing and are shown in RSI numbering, the wheelbase in centimetres (17 means 170mm). Fitment is a starting point: final mounting position is set on the boot, and personal preference runs a size either way for some skaters.
Riedell and Harlick publish no boot-to-plate charts for Roll-Line, Komplex or Rollerskatesitalia plates, so the Riedell and Harlick rows are calculated estimates from a wheelbase bridge: each boot size is matched to the wheelbase of the plate its maker mounts as standard (Riedell from its PowerDyne Arius chart, Harlick from its foot-length chart), and the largest plate at or under that wheelbase is shown. Every such row is labelled a derived estimate, and Brock is validating the estimates against real plates. Treat them as a starting point: a size near a step boundary can land one step off.
