When deciding on the cake size for your event, you should review a cake portion and serving guide before deciding on the perfect cake size. This will give you a general idea of what size cake to order to achieve the desired number of servings needed.
As a rule, plan on one serving per guest. But, if you’re looking to cut your costs you can always go with a fewer number of servings since not everyone will eat cake, especially if you’re having other types of desserts.
