What is a wedding cake serving guide?

A serving guide for a wedding cake is a simple way to match your cake to your guest list. The general rule is to plan for one slice per guest, though you may need fewer if you are serving a full dessert course, and more if the cake is the only sweet thing on offer. Some couples like to have a small cake for cutting and photos, then serve a larger sheet cake to guests, which can be a practical and cost-effective approach.

Your baker will have a cutting chart that shows how many slices each tier size gives you. For example, a six-inch round cake might serve around 10 people, an eight-inch around 20, and a ten-inch around 30, but these numbers vary with slice size and cake height. Taller cakes can be cut into thinner slices, so a three-tier cake often serves more than the sum of its tiers suggests.

Think about whether you want a dessert-style slice or a smaller finger slice. If the cake follows a big meal, smaller slices are fine. If it is the main sweet treat, allow a generous portion. Always tell your baker your final guest number and ask for their recommended tier sizes.
