Ok. I can never figure this out. Please help!! I have a friend that wants a cake, round, to serve 120 people. I know you don't count the top tier in the total. Do you ususally use a 6 inch pan for the top for the anniversary cake? How many tiers will I need and What sizes?
I just keep an old Wilton Yearbook around-they have a breakdown of servings in all of them. For round, if you're not using the top 6" tier for servings, I would do 12", 10", 8" with 6" for anniversary. I usually give my brides the option of the take home tier but tell them there is a difference in price. I charge per slice and add in the 12 servings the 6" would feed if they are going to take it home. It's usually not that much of a difference.
I would go with 6,8, 10, 12. Usually thats personal for the top tier. But what we do is if they bring a photo of their cake on the anniversary day we make them a 6 inch cake for free.
Seems to work great!
Per Wilton wedding cake serving chart (which in on their website) 6/8/10/12 serves 132 using the whole thing, 120 saving the top tier.
