Size guide
Which size to choose
Our children’s clothes are sized by age, and each piece is engineered to fit through five to seven conventional sizes: the pleats expand as your child grows.
- Match the age first. TinyHuman fits 0 to 12 months, MiniHuman 9 months to 4 years and LittleHuman 4 to 9 years. Merino knits, the Flight Series and Foldwear Mini have their own ranges, shown in their charts.
- Check the measurements. Compare your child with the size charts below. Each measurement runs from the garment’s smallest setting to fully grown.
- Between sizes? Size up. You’ll get more wear as they grow into it. From about 10 months, that means MiniHuman.

Merino knitwear
Our Knot-Tile® merino is sized by age too (the ranges are in each chart), and the knit stretches more freely than the pleats. Choosing between two sizes? The smaller will feel snug at first; the larger gives you more total wear.
