From each brand’s own charts, linked: the other side’s size where the chart prints it beside this one, or both sizes on one row; otherwise the row on the other chart with the same EU (or UK) size; otherwise the nearest foot length, within 3 mm. “Foot” is the brand’s own foot length for 6.5Y, where its chart gives one, not for the size it maps to. Highlighted rows differ from the standard tables. Not affiliated with any brand.

Who wears 6.5Y?

The median child’s foot reaches this size at about 13½ years, in the US Consumer Product Safety Commission’s survey of children.

The foot each brand’s own chart makes 6.5Y for runs from 24.0 cm (Veja) to 26.3 cm (Golden Goose) across 11 charts; the standard size tables make it for a foot up to 24.1 cm. Pick the brand whose foot length is at or just above yours.

Foot Locker and ASICS both call 6.5Y GS (grade school).
