Piston Size

Is there a way I can find out if my pistons are over size or standard size by the numbers on them?
Thanks

Some stamp the oversize on the tops....some don't. On the Toyota, it would be metric in the form of .25, .5 .75 and 1.0. Carb cleaner and tooth brush cleaning of one of them may reveal a number.

Well on my pistons, the top says 2 2 on different sizes, but i dont think this means anything because the other ones say 2 3, 2 4, and 2 1. On the sides it says 3503 then Toyota on one side. On the other side it says ART and 26P.
Thanks for the help
