I have a school project and i can get extra credit if i do it on a ceiling tile that will be hung in class, so to all contractors,or people that just know the answer please answer as fast as you can!
If you mean the drop-in tiles that fit into the metal grids, there are 2 sizes, 2ft x 2ft. and 2ft. x 4 ft. You can get them at lowes or home depot.
