measuring it is the only way to get an accurate size. The sizes are so close together that if you try to guess you may be wrong. When your talking about tenths of mm and such its like splitting hairs...literally. If you don't have the equipment to measure it, take it to a bike shop or a machine shop, they will have a caliper that can measure it.
Good Luck
