Appetites vary, and no slice of cake is ever cut the same. However, it’s always useful to have an idea, so have created a portion guide below..
Below is tables to assist in giving an approximate guide to what size cake you may need for your number of guests.
Usually cake given out at weddings and special occasions is sized as a finger portion [1”x 1”x 3”] .
If you are serving cake as dessert you will need larger slices [1”x 2”x 3”] please bear this in mind for smaller gatherings such as birthdays.
For example for a birthday an 8” round cake will serve around 20 people.
All cake portions are worked out from cutting the cake in a grid pattern as it is easier to maintain equal servings.
