The Unknown Children — Size Guide

Our kids streetwear is sized to fit comfortably with a little room to grow. Sizes are based on your child's age, but every kid is a bit different — if your little one is between sizes, we recommend going up.

Tops, Bottoms, Hoodies, Jackets & Sets

Size	Age	Height	Chest
1	12–18 months	76–83 cm	47–50 cm

Toddler Onesie

The Toddler Onesie uses month-based sizing.

Size	Age	Height
3M	0–3 months	56–61 cm
6M	3–6 months	62–67 cm
9M	6–9 months	68–71 cm
12M	9–12 months	72–77 cm
18M	12–18 months	78–82 cm
24M	18–24 months	83–87 cm

How to measure your child

Height — stand them flat against a wall (no shoes). Measure from floor to top of head.
Chest — wrap a soft tape around the fullest part of their chest, just under the arms. Snug, not tight.
Waist — around the natural waist, just above the belly button. Keep the tape relaxed.

Still not sure?

Email us at theunknownchildren.au@gmail.com with your child's height and age and we'll recommend a size. We're a small Aussie team — we usually reply within 24 hours.

Note: sizing is a guide. Cotton fabrics may shrink slightly with first wash. We recommend cold wash + low tumble dry to minimise shrinkage.
