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 1.5Y, 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 1.5Y?

The median child’s foot reaches this size at about 8 years, in the US Consumer Product Safety Commission’s survey of children.

The foot each brand’s own chart makes 1.5Y for runs from 19.5 cm (Vans) to 21.0 cm (Golden Goose) across 5 charts; the standard size tables make it for a foot up to 19.9 cm. Pick the brand whose foot length is at or just above yours.

Shops label 1.5Y differently: Foot Locker calls it PS (preschool) and ASICS GS (grade school), so search both labels.
