Which cake size should I get for my wedding?

Choosing the perfect cake for your wedding is a big decision that needs careful thought. One essential thing to keep in mind is the cake size, which should be based on the number of guests you're expecting. It's important to make sure that everyone gets a piece of your scrumptious dessert!

To figure out the right cake size, you need to first think about whether the cake will be the only dessert or if you're planning to have other sweet treats like cupcakes or a dessert table. If you're only serving cake, make sure you have enough for all your guests.

Wedding Cakes vs. Celebration Cakes

Wedding cakes are designed to be taller, allowing for larger portions. This way, the cake can be served as a delightful dessert at the end of the meal. It allows the overall height of the cake to be taller, elegant and accomodate more flowers.

It is a long-standing tradition for couples to save the top tier of their wedding cake to enjoy on their first anniversary. The larger size allows for this portion to be set aside for the future celebration.

What to Consider:

Estimate the Number of Guests:

Begin by estimating the total number of guests attending your wedding. This will be the starting point for determining the cake size.

Portions per Person:

For traditional wedding cake portions, plan for 1-2 slices per guest. However, if you're serving additional desserts or if your guests are not big cake eaters, you can consider smaller portion sizes.

Cake as the Only Dessert:

If the wedding cake is the main dessert and there won't be other desserts served, ensure that the cake is large enough to accommodate all your guests. As a guide:

  • 1 x two-tier cake serves 60 guests
  • 1 x three-tier cake serves 100 guests
  • 1x four-tier cake serves 150 guests.

For larger weddings, consider adding more tiers or opting for a sheet cake to supplement the main display.

Cake with Other Desserts:

If you're serving other desserts alongside the wedding cake, you can adjust the cake size accordingly. Consider a smaller cake, such as a one or two-tier cake, that serves a portion of your guests. This way, you can have a variety of desserts for everyone to enjoy.

Consider Cake Decorations:

Keep in mind that intricate cake designs and decorations may take up more space on each slice. If you have elaborate cake decorations, you might need a slightly larger cake to ensure everyone gets a good share of the decorations.


The wedding cake is not just a delicious treat but also a beautiful centerpiece that adds to the celebration. Choose a cake size that fits your guest count, budget, preferences, and complements the overall theme and style of your wedding.
