Frequently Asked Questions: 12 Year Old Shoe Size
Helpful fit allowances, measuring wisdom, and sizing advice for parents.
What shoe size does a 12 year old wear?

How fast do 12 year old feet grow?
Feet grow more slowly now — about 0.5–1 mm per month. Check fit every 4 to 6 months.
Should I buy shoes bigger for my 12 year old?
Pediatric podiatrists recommend 10–12 mm (roughly a thumb's width) of clear space between your child's longest toe and the front of the shoe. This accommodates natural growth without being so large that the shoe causes tripping or blistering. Never buy more than one full size up.
How do I measure my 12 year old's foot at home?
Stand your child barefoot on a sheet of paper against a wall. Mark the longest toe with a pencil held at 90°. Measure from the wall edge to the mark in millimeters. Measure both feet and use the larger number. Our interactive calculator converts this measurement to the exact shoe size.
