Eli5: Why do shoes have half sizes, rather than double the amount of whole sizes?

331 views

Especially cause shoe sizes aren’t really universal anyway, making the half sizes even less meaningful. Why?

Because they used to only do whole sizes before companies figured out that there’s need for more resolution. Starting a new standard is a whole lot harder than just writing ½ at the end of the size designator.

The original shoe sizes used in English speaking countries were in barleycorns which is an old fashioned imperial unit for a third of an inch.

Also while they changed around what shoe and clothes sizes means a number of times, they learned that for female customers smaller number for size are more popular so switching some other smaller unit (like line which is 1/4 of a barelycorn and 1/12 of an inch) would have made the size number sound bigger and less attractive to some customers.

European size units are way smaller (from 20 for a baby to 47 for a 7ft male) and we have half sizes too. So that’s hard to avoid.

In Europe we use two sizes – the original based on the barley corn, and the Paris point. The paris point is smaller, and a size 10 UK is a size 41 EU.

which came first: the music note question or the shoe size question?

Using Japanese sizing is a good idea because they use centimeters so it’s a more accurate metric for measuring shoe size, opposed to normal sizes that can vary from manufacturer to manufacturer. Some shoes say “JP” or “CM”. So once you know your shoe size in CM, in theory, you should always find the right fit.

European sizes came later, but based on the metric system.

Isn’t half a size extra width?
