Babies and toddlers grow incredibly fast in their first years of life.
Baby and toddler clothing sizes are generally based on height in centimeters. But what do these sizes actually mean, and what should parents pay attention to?
How do baby and toddler sizes work?
Baby clothing sizes usually start at 50 cm immediately after birth, which corresponds to newborns.
From there, they increase in 6-cm increments:
- Size 50Newborns (up to approx. 50 cm in height)
- Size 561-2 months
- Size 622-3 months
- Size 683-6 months
- Size 746-9 months
- Size 809-12 months
- Size 8612-18 months
- Size 9218-24 months
- Size 982-3 years
These figures are only guidelines, as every child grows differently. Some babies are already taller than 50 cm at birth, while others are shorter. Furthermore, children develop at different rates: while some grow quickly in height, others remain at a certain size for longer.

What should parents pay attention to?
- Room for growth: Choose clothes that are a little bigger so your child can grow in them – but not so big that they become uncomfortable.
- Differences between brands: Attention – sizes can vary depending on the brand! Some brands run small, while others are more generously sized. It's best to try new brands before buying larger quantities.
- Comfort and freedom of movement: Make sure that the clothing is not too tight and offers enough room for diapers, rompers, and movement.
- Season-appropriate planning: Remember that babies often grow faster than a season lasts. So, if a thick winter jacket is approaching, it's best to choose the next size up.
Practical tips for parents
- Check sizes: Check regularly and early enough to see if your child needs the next size up. This way you'll be well prepared and avoid stress.
- Sorting as a ritual: Take your time, hold your favorite items in your hands one more time and reminisce together.
- Upgrade your basics: Invest in simple, easily combinable clothing items that are easier to replace.
- Consider sustainability: Secondhand clothing is a great option to save money and shop sustainably.
The rapid development of babies and toddlers can be challenging for parents, but with a little planning, choosing the right clothes becomes easier and can even be fun. And don't forget: there's no "perfect" growth path – every child develops at their own pace!
