A friend asked me to make this cake for her wedding in May. I'm no good at judging cake tier sizes. Any help would be greatly appreciated. She wants it to serve 100, so I'm trying to figure what size pans to use to get the proportions right for this cake. Thanks.

That looks like 6" 10" 14" (105 servings)or maybe 4" 8" 12" (76 servings)

The info is here: http://www.wilton.com/cakes/making-cakes/baking-party-cake-2-inch-pans.cfm

It looks to me like 4, 8, 12.. I got one of this in my photos. The bride and groom look like they take most of the size of the upper cake. Wich would be a 4.
