Q. What size cake will I need?
A. That depends on how you will be using it. Will it be on display for most of the evening and cut toward the end? Will some of your guest have come and gone before you cut the cake? Usually a 3 tier cake will be enough to serve those who are there toward the end of the evening.
Is the cake serving as dessert after a sit down dinner? In this instance you need to be sure you have a nice sized slice for each guest, which usually requires a larger cake.. "Dessert slices" are larger than a "reception slice" shown on the price & servings chart.
