There are two sizes of taper for cranks, ISO and JIS, with the JIS being slightly larger. You can usually get away with putting ISO cranks on a JIS spindle, but if you go the other way it may not tighten.

Look at Sheldon Brown's website for a very good explanation of the difference betweeen ISO and JIS and for identification of different cranks.
