Understanding kids’ clothing sizes (EU, height, and labels)
How EU numbered sizes relate to height, why two “116” garments can fit differently, and how to use measurements alongside labels.
Height-based sizing in Europe
Many European children’s labels use a number roughly tied to the child’s height in centimetres (for example, size 104 is often intended for a child around 104 cm tall). It is a guide, not a guarantee: torso length, build, and brand cut all change the fit.
Brands sometimes add “wide” or slim fits, or age ranges on the hang tag. Treat age as marketing; height and chest measurements are more comparable across shops.
Why the same size number fits differently
Pattern shaping, seam placement, fabric stretch, and intended use (slim jeans vs. relaxed sweatshirt) change how a garment feels. Two pairs of trousers both labelled 110 can differ in length and waist.
Seasonal layers matter: a winter jacket may be sized to fit over knitwear; a base layer may be sized skin-tight. Check the brand’s own size chart when possible.
Using measurements with WhatSizer
WhatSizer uses your child’s height, optional age, and growth reference data to suggest a clothing size band for your region. Always try garments on when you can, especially for shoes and outerwear.
If your child is between two sizes, consider how soon you need the item to fit and how much you value extra room for growth versus a neat fit today.
