Sizing conventions vary by brand and by cut — this table shows the standard published conversion. Always check the garment's own size chart when one is available. See how these tables are compiled.
Working the chart the other way, a EU 74-80cm baby size lines up with a US 9-12 months size — the translation needed to turn a European brand's height label into the age-band language US retailers use.
If you know your baby's actual height rather than just their age, matching that centimetre figure directly against the EU chart (rather than going through the age conversion at all) usually gives a better first fit.
Frequently asked questions
Should I convert by age or by my baby's actual height?
By actual height if you have it — the EU chart is built on height in centimetres, so matching your baby's measured length directly skips the extra rounding that an age-based conversion introduces.
