Easily determine baby and children's sizes: The Neworn size guide for baby & children's clothing
Children grow quickly – often faster than you can keep buying new clothes. Since brands and manufacturers interpret cuts differently, our size guide helps you choose the right baby and children's clothing straight away. This way, you avoid bad purchases and returns and are guaranteed to find the right garment for every age.
Which size fits which age?
In German-speaking countries, clothing sizes for babies and children are primarily based on body height in centimeters. For newborns, the size selection usually starts at size 50-56 cm. For babies in their first year of life, size 62-68 cm and size 74-80 cm are the main companions during the first growth spurts. Toddlers and kindergarten children often wear size 92-98 cm or size 104-110 cm, before sizes from 128+ cm are needed for school-age children.
Fit tips by category
Depending on the garment, it is worth taking a closer look at the cut and the elasticity of the material:
-
Newborn essentials & basics: For bodysuits and rompers, it is advisable to choose the larger double size in case of doubt, so that there is enough room for a cloth diaper. If you are looking for a coordinated wardrobe right from birth, you can save a lot of time putting it together with our practical baby & children's bundles.
-
Everyday clothing: For trousers, an adjustable waistband ensures a perfect fit, even if the leg length is still generous. If you are wavering between two sizes for T-shirts or sweaters, it is best to choose the larger version to grow into. For jackets, it is also recommended to go one size up so that thick sweaters can fit underneath in a layered look.
-
Accessories & seasonal items: For dresses and skirts, it is best to orient yourself by the length of the upper body. For swimwear, the fit should be snug so that nothing slips. Soft, stretchy hats and socks should be flexibly elastic without leaving pressure marks.
How do popular children's brands fit?
Brands like NAME IT usually offer a reliable, true-to-size fit for everyday life. Those looking for sustainable organic quality appreciate Scandinavian brands such as Müsli by Green Cotton or Petit Piao, which are often cut a bit more generously. Natural textiles from PURE PURE by Bauer, Popolini, or Organic by Feldman impress with their stretchy fits, while brands like The New offer modern cuts for older kids.
