Could someone please tell me where I can get a chart/book/anything that will tell me how many servings the various pan sizes provide? I am not quite sure which pans will accommodate the amount of servings needed for various functions. Thanks for any help!

Everything you need to know to bake, assemble and decorate tiered, stacked or layer cakes:

The Wilton links to cake preparation and servings guides in the above thread will provide that info for both party and wedding servings whether using 2" or 3" pans.

Thank you, JanH!! That's exactly what I needed!!
