Kids Shoe Sizing FAQ
Helpful answers to common questions about measuring, fit allowances, and international shoe conversions.
How do kids shoe sizes convert to women's shoe sizes?
In the US footwear system, Big Kids / Youth (Y) sizes convert to Women's sizes by adding approximately 1.5 to 2 sizes. For example, a youth 4Y is equivalent to a women's 5.5, a 5Y equals a women's 6.5, and a 6Y equals a women's 7.5. Widths in kids' shoes are roughly equivalent to a women's standard 'B' width.
How do I convert inches to kids shoe sizes?
To convert foot length in inches to a US kids shoe size: measure your child's foot in inches, add 0.5 inches for wiggle room, and cross-reference our size chart. For example, a foot measuring 5.5 inches corresponds to a US 7C toddler size, a 6.7-inch foot corresponds to a US 11C little kid size, and an 8.5-inch foot corresponds to a 3.5Y youth size.
What is the difference between Toddler, Little Kid, and Big Kid sizes?
Toddler sizes typically cover US 1C to 10C (approx. 9 months to 3.5 years). Little Kid sizes cover US 10.5C to 13.5C (approx. 3.5 to 6 years). Big Kid / Youth sizes cover US 1Y to 7Y (approx. 6 to 12+ years). After size 7Y, sizing moves into adult sizes.
Which kids shoe brands run small or narrow?
Nike, Puma, and Converse (All Stars) typically run narrow or snug, so sizing up by half a size (+0.5) is common for wider feet. Brands like Adidas, Skechers, and Stride Rite are known for roomier toe boxes and true-to-size fits.
Can I print a kids shoe size chart at home?
Yes! You can use the 'Print Size Chart' button on our Size Chart page to print a clean, high-contrast reference table directly from your home printer.
How do I know if my child's shoes are too small?
Signs of tight shoes include red marks or blisters on the toes or heel, curled toes, reluctance to walk, the child constantly kicking off their shoes, or having less than 5 mm of space between their longest toe and the tip of the shoe.
Should I buy shoes one size bigger for growing room?
No, you should not automatically buy an entire full size bigger (e.g. buying a size 13 when they measure a size 11). Buying shoes that are too large causes tripping, blisters from heel slipping, and improper foot muscle development. Instead, buy shoes that have approximately 10 to 14 mm (~1/2 inch) of toe room.
Do boys and girls wear different shoe sizes?
No. Children's shoe sizing in the US, UK, India, and EU is unisex. A size US 11C is the same length whether labeled as a boy's shoe or a girl's shoe. Widths and styles may vary slightly between brands, but length sizing is identical.
How accurate is the Kids Shoe Size Calculator?
When using foot length mode, the calculator uses exact millimeter measurements cross-referenced with major brand footwear size charts (Nike, New Balance, Clarks). Because individual shoe brands shape their lasts differently, our result is an honest, highly accurate starting recommendation — we always suggest verifying with the specific retailer's size chart before buying.
