Size Guide

Finding the perfect fit is important when choosing baby and children’s clothing. Use our guide below to help select the most suitable size for your little one.

This guide is based on average sizing and may vary slightly between brands and styles.

Clothing

Choose by your child’s height where possible, as age can vary between children.

Shoes

Measure from heel to toe and allow a little extra room for comfort.

Fit Advice

How to measure baby shoes

  • Place your child’s foot flat on a piece of paper.
  • Mark the heel and the longest toe, then measure the distance.
  • Allow a little extra room for comfort and growth.
  • For hard sole shoes, check the fit carefully if your child is already walking.
