Size Guide

Kids' Shoe Size Guide

Every child's foot is a little different, so rather than guessing by age or usual shoe size, we recommend measuring their feet. Grab a piece of paper, a pencil and a ruler, it takes less than a minute.

How to Measure

1. Stand your child barefoot on a piece of paper.
2. Trace around both feet with a pencil held upright.
3. Measure from heel to longest toe.
4. Use the longer foot measurement.
5. Match this measurement to the size chart for the style you're ordering.

Fit Guidance

If your little one falls between sizes, we recommend sizing up. A little extra room gives growing feet space to move comfortably.

Growing Room

Kids' feet grow quickly, so a little extra length gives them room to grow into. Age and usual shoe size are only a guide, their foot measurement is what matters most.

Princess and Jelly Sizing

Our Princess Collection and Jelly Shoes use different sizing systems, so each has its own size chart below.

Princess Collection runs LUMI SIZE 24 to 29.

Jelly Shoes run JELLY SIZE 22 to 27.

Always measure your child's foot and use the size chart for the specific style you're ordering, even if they already wear another LUMI Move style.
