I'm sure there is a web-site of some sort to determine what size cake to feed how many people. Would someone please point me in the right direction? I have friends/family that want me to make cakes but I don't know what size cake to make to feed how many people. Thanks

You can find an guide under the articles tab.

Wilton's web site also has cutting guides that are helpful, here's a link: http://www.wilton.com/cakes/cake-cutting-guides/wedding-cake-cutting-guide.cfm

Found it. Thanks so much!
