Why conversions don't always match
EU sizes go up in steps of about two thirds of a centimetre; UK sizes go up in steps of a third of an inch. The two never line up exactly, so every brand rounds a little differently. Boden's chart, for example, agrees with Next that UK 10 is EU 28, but puts UK 9.5 at EU 27 where Next has EU 27.5, and UK 2 at EU 34 where Next has EU 34.5. Half-size disagreements like that are normal.
So when a European brand lists foot length in centimetres, use that instead of the converted size. Measure your child's foot (how to measure) and choose the size whose foot length is the same or just bigger.
US sizes
US children's sizes are a half to one size bigger than UK at the same foot length: UK 10 is US 11 on Next's chart and US 10.5 on Boden's. US sizes also restart after 13.5, but on Next's chart a US 1 is a UK 13.
Questions
What is EU 30 in UK kids’ sizes?
Next converts EU 30 to UK 11.5 (child). Brands vary by up to half a size, so check foot length too.
What is EU 28 in UK kids’ sizes?
UK 10 (child) on both Next’s and Boden’s charts.
Is a US kids’ size bigger than UK?
Yes, by about half to one size for the same foot. Next converts UK 10 to US 11; Boden to US 10.5.
