Check height first
The size chart works most accurately when you use height as the primary reference, not age alone.

Size chart by age and height

The short version
Children's clothing sizes vary slightly between brands, but height gives the most reliable guide. For everyday wear, choose soft and slightly roomier cuts that leave growing room.
How to use the chart
Check chest and waist
If the child is between two sizes, chest and waist measurements help decide whether a slimmer or roomier fit works better.
Leave room to move
Children's clothes must allow running, crouching and playing — a small amount of extra room is both practical and comfortable.
Practical tips
- Measure the child in a thin shirt or bodysuit for the most accurate result.
- For winter clothes or tracksuits, go for a slightly roomier fit.
- Soft, stretchy fabrics give more wearing time than stiff materials.
- If the item is oversize or loose-fit, don't automatically size up.
Browse categories
Once the size is sorted, the next step is choosing soft, movement-friendly clothing for an active child.

Frequently asked questions
Is the children's size chart based on age or height?
Height is the most reliable guide. Age only gives a rough indication — two children the same age can need different sizes.
What if the child falls between two sizes?
For everyday wear, the larger size is usually better — especially if the fabric does not stretch, or if you want the item to last the whole season.
Do oversize items need to be sized up?
Usually not. Oversize and loose-fit designs are already cut for a roomier fit — check the brand measurements and the child's height.
How do I measure a child's height correctly?
Stand the child against a wall without shoes, feet together. Place a flat book on their head level with the wall and mark the spot. Measure from the floor to the mark.
