Size guide

Sizes are based on your child's age:

• 1 = 12–18 months
• 2 = 2–3 years
• 3 = 3–4 years
• 4 = 4–5 years
• 5 = 5–6 years

For exact measurements see the chart below.

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

Toddler Onesie

The Toddler Onesie uses month-based sizing.

How to measure your child

1. Height — stand them flat against a wall (no shoes). Measure from floor to top of head.
2. Chest — wrap a soft tape around the fullest part of their chest, just under the arms. Snug, not tight.
3. 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.
