Kids Shoe Size Chart by Age for US, UK & EU
Find the right shoe size for your child using our kids shoe size chart by age with US, UK and EU conversions, plus foot measuring tips and guidance on how often to size up.
Kids shoe size charts organized by age are convenient, but age alone is never the most accurate way to determine a child's shoe size — children the same age can differ by several sizes depending on their individual growth patterns. The most reliable approach combines age as a starting point with actual foot measurement for precision. Our Kids Size Converter gives you both age-based and measurement-based options.
Newborn to Toddler Shoe Sizes (0 to 3 Years)
Newborn and infant sizes run from US 0 to 4 (EU 15 to 20) for the first year. During this stage, soft-soled shoes or booties are common because babies are not yet walking. Toddler sizes from US 4.5 to 9 (EU 20 to 27) cover roughly ages 1 to 3, when children begin walking and need more structured soles for stability and protection.
Youth and Grade School Sizes (4 to 12 Years)
Once a child outgrows toddler sizes (around US 10 to 13, EU 27 to 31), they move into youth or grade school sizing. This range covers roughly ages 4 to 10 or 12, reaching up to US 7Y (EU 40, UK 6). Growth during this period is more gradual than the toddler years, but still requires checking every four to six months to catch size changes before shoes become uncomfortably tight.
How to Measure a Child's Foot at Home
Have your child stand on a sheet of paper against a wall with their weight evenly distributed. Mark the longest toe and the back of the heel, then measure between the marks in centimeters. Measure both feet because one is usually slightly longer, and always choose the larger foot's measurement. Repeat the process every few months and use our Shoe Size Converter to match the measurement to US, UK, and EU sizes instantly.
