Organic Zoo publishes both child-height guidance and style-specific garment measurements. These are different measurements: choose the relevant style table rather than applying one chart to every garment.
About Organic Zoo sizing
Organic Zoo publishes its charts by age band. Garment measurements are in cm and differ by style.

The selected older-child tables use age bands such as 1–2 years rather than a separate 18–24 months row. Organic Zoo also publishes newborn and baby charts; the table and style must match.
How to measure
For height guidance, measure your child without shoes. For the garment tables, lay a similar well-fitting garment flat and compare the labelled length, width or waist dimension. Do not compare flat garment width directly with body circumference.
Frequently asked questions
My child is between two sizes. Which should I choose?
Compare the measurements for the exact style before deciding. Age labels are only a starting point; contact us if the measurements fall between sizes.
Still not sure?
Email us at support@littlewildkid.store with your child's age and height and we'll help you choose.
