Most parents buy the next size up the moment a shoe feels snug \u2014 but kids’ feet grow in predictable bursts, not a steady line. Knowing the typical shoe size at each age, and how many months you get out of a pair, saves money and prevents the blister-and-black-toenail problems that come from squeezing a growing foot into a shoe that was “fine last month.”<\/p>\n

For a quick frame of reference, use our baby age calculator<\/a> to pin down exactly how many months old your child is \u2014 the sizing intervals below are measured in months, not birthdays.<\/p>\n

These are medians from pediatric growth data. Real children spread across roughly \u00b11.5 sizes at any given age, so a 5-year-old in a size 13 is just as normal as one in size 10.<\/p>\n

Why Age Is Only Half the Story<\/h2>\n

Foot length tracks height more closely than it tracks age. A child in the 90th percentile for height will usually wear a larger shoe than the table suggests; a child in the 10th percentile, a smaller one. If you already track height, the same growth chart logic applies: a foot grows about 1 cm per 2.5\u20133 months during toddler years, then slows to roughly 1 cm per 6 months after age 7.<\/p>\n

Two rules of thumb that hold up in practice:<\/p>\n
