About this chart

Okaïdi (kids, 2 to 14 years) and Obaïbi (newborn and baby) are two brands from the same group and share a size guide. All measurements are published in centimetres. Socks and tights (shoe size by age) are not reproduced.

Baby

The Obaïbi range goes from premature to 5 years. Its "23 M" size corresponds to the age of 2. Obaïbi's 3 to 5 year sizes do not have quite the same measurements as Okaïdi's.
