Guest List Size: The number of guests attending your wedding determines the size of the cake. The larger the guest list, the bigger the cake needs to be.

Slice Size: The size of each slice also influences the overall cake size. Traditionally, wedding cakes are cut into 1-inch by 2-inch slices, but this can vary depending on your preference.
