How to tell/differentiate 63 crank from 64 crank

Basically like the title states, how to tell which crank is which? Is there anything that stands out? I'm a noob. I know the 63 = 88mm and the 64 = 100mm but where does that get measured?

Any visual way to tell just by looking? I don't have anything to get an accurate measurement at the moment
