The size of the wedding cake usually depends on when it is being served. For example, is it pudding for everybody or a snack later on? The couple should think about whether they want any leftovers, but remember it is likely that not everybody will have a slice.

Here are some rough guidelines:

Square Cakes

8 inches  = 50-60 servings

10 inches = 80-95 servings

12 inches = 120-140 servings

Round Cakes

8 inches = 30-40 servings

10 inches = 60-70 servings

12 inches = 90-110 servings
