All ages in the chart are approximate. For length, our chart uses the measurement of the foot rather than the shoe. First, measure the length of the foot while standing and wearing the socks that will be worn with the new shoes. Then, take the length measurement and find the corresponding U.S. shoe size in this chart.

How to measure without a ruler or tape measure?

If you don't have a ruler or tape measure handy, you can try to measure with a standard credit card, which has a width of 3 ⅜ inch or 8.56 cm and a height of 2 ⅛ inch or 5.4 cm.

If you do a lot of online apparel shopping, accurate body measurement using a tape measure is a must. The actual tape you choose doesn’t matter that much. This retractable one is very easy to use, and the fact it uses both CM and IN is extremely helpful.
