US Shoe Size Conversion Calculator

I’m so excited to be debuting this US shoes size conversion calculator that my team built for me. It will let you do a number of shoe size conversions.

One, you can convert from women’s to men’s sizes in shoes.

Two, you can convert from men’s to women’s shoe sizes.

Three, you can convert youth sizes to either men’s or women’s shoe sizes.

And, finally, you can convert either men’s or women’s sizes to youth shoe sizes.

It’s like being able to use the foot measuring device from device from an old-fashioned shoe store–called a Brannock device–but you can use it online.

  • 5
  • 5.5

Of course, I have to offer this caveat: this is just a general estimation on calculating size conversions.

In this article on youth to women’s sizes, I point out how brands like Adidas, Nike and Converse may not have the same results as our custom-built size converter. That’s because some of these brands run bigger or smaller than others.

Nonetheless, I hope you’ll have fun playing around with this shoe size calculator.
