The toddler shoe size chart converts foot length or age to US, UK, and EU shoe sizes for infants through teenagers. Toddler feet grow fast — measure every 2–3 months and always leave 1/2" of growing room at the toe.

How to Measure Children's Feet for Shoe Size
Buying shoes that fit correctly prevents foot problems and supports healthy development. This toddler shoe size chart converts foot length to standard sizes in US, UK, and EU systems.
Measurement Technique
Have your child stand on a piece of paper (weight-bearing spreads the foot to its true size). Trace the outline of both feet. Measure from the heel to the tip of the longest toe. Add 1/2" (12mm) for socks and growing room. Use the larger foot measurement. Do this in the afternoon when feet are at their largest.
Shopping Tips
Try shoes on at the end of the day. Ensure there's thumb width of space at the toe — the shoe should not bend at the arch. Young children's feet grow 1–2 sizes every 3–6 months; check fit regularly. Wide-width options (W or EW) are available for children with wider feet.
FAQ
Is this toddler shoe size chart free?
Yes, completely free.
How often do toddler feet grow?
Toddlers (1–3 years) can grow 1–2 shoe sizes every 6 months. Children 3–5 years grow about 1 size per year. School-age children (6–10) grow about half a size per year. Measure feet every 2–3 months for toddlers, every 6 months for older children.
How much growing room should children's shoes have?
Children's shoes should have 1/2" to 3/4" (12–19mm) of growing room at the toe. Press your thumb between the longest toe and the front of the shoe — you should fit one thumb width. Too much room (over 1") makes the shoe unstable; too little causes blisters and toe issues.
What is the difference between toddler and little kid shoe sizes?
Toddler (T or TD) sizes run 4T–10T (fits approximately ages 1–4). Little kids (K or C) sizes run 10.5–3 (approximately ages 4–7). Big kids (Y or Youth) run 3.5–7 (approximately ages 7–12). Sizes overlap — a 10T and a 10K are the same length but may differ in width.
How do I measure my toddler's foot at home?
Place foot on white paper, stand (not sit — feet spread under weight), trace outline. Measure longest toe to heel. Add 1/2" for sock thickness and growing room. Measure both feet — go with the larger one. Measure in the afternoon when feet are slightly swollen from activity.
