What to consider before choosing wedding cake size?

Number of guests
- The size of your wedding cake will largely depend on the estimated number of wedding guests. Remember not all guests will eat cake, but it is customary to at least serve each of the guests a slice of cake.
Do you want extra cake left over?
- We kept a full tier of our cake as “extra” for the day after our wedding. We enjoyed it with them with tea and coffee in the afternoon before everyone headed home!
Design & Style
- Firstly, you will need to decide if you are having a round cake or a square cake.
- Secondly you will need to decide on portion sizes. A finger portion is often served at events and are about 1″ wide and 5″ tall. While dessert portions (also known as “party portions” are slightly bigger, about 2″ wide and 5″ tall.
Budget
- The bigger the cake, the more it will cost. We found a cake maker through our friends and family who gave us a nice discount – ask about if budget will be tight, you’ll be surprised how helpful people are!

What size is a traditional wedding cake?

For those of you who wanting to dodge tradition, good news – there is no historically standard wedding cake size. The size of your wedding cake depends on factors such as the number of guests, design preferences, and cultural traditions.

As a general rule of thumb, a two-tier cake can serve around 30-50 guests, a three-tier cake can serve 50-100 guests, and so on. Stick to our wedding cake portion guide below and you won’t go far wrong.
