Where the European and British children's scales meet

The children's UK scale runs up to UK 13.5 and then restarts at UK 1 as the foot keeps growing, so no single offset links the two columns. Around that rollover the EU side keeps climbing steadily, which is why EU 35.5 sits where the UK number has just reset.

The European children's number climbs steadily while the British one restarts at 1 in the big-kid range, so the two align differently above and below that turn. Growing room is the real variable a chart cannot show: WMS fitting in Germany allows roughly 9 to 15 millimetres in front of the toes in new children's shoes, enough for a couple of months before a remeasure. Read the table for the number and the guides for the room, because a child outgrows the fit long before the shoe wears out.

Common questions

Why do EU and UK kids' sizes drift apart?

The British scale resets at 1 partway up while the European scale does not, so their relationship changes across that point.

How much toe room should a child's shoe have?

Fitting systems allow roughly 9 to 15 millimetres of space ahead of the longest toe, which lasts a couple of months of growth.
