How big of a wedding cake do I need for 100 guests?

Answered by James Kissner

To determine the size of a wedding cake needed for 100 guests, it is important to consider the number of tiers and the serving size of each tier. In general, a classic three-tier cake is commonly used to serve around 100 people. Let’s break it down.

The bottom tier, typically a 12-inch cake, is the largest and serves the most people. A 12-inch cake can serve anywhere from 40 to 60 people, depending on the size of the slices. This is a versatile tier that can accommodate a larger guest count.

Moving up to the middle tier, a 10-inch cake is commonly used. This size serves approximately 30 to 40 people. Again, the serving size and the way the cake is sliced will determine the exact number of servings.

The top tier is usually an 8-inch cake, which serves around 20 to 25 people. This tier is smaller and usually reserved for the couple to save for their first anniversary or for close family and friends.

By combining the serving estimates for each tier, we can see that a classic three-tier cake with 12, 10, and 8-inch layers can serve about 100 people. However, it is essential to consider the serving size and the preferences of your guests. Some people may want larger slices, while others may prefer smaller portions.

It’s also worth noting that these serving estimates are just guidelines. The actual number of servings may vary depending on how the cake is cut and served. If you are concerned about having enough cake for all your guests, you may want to consider adding additional sheet cakes or cupcakes to supplement the main wedding cake.

Another factor to keep in mind is the design and style of the cake. Intricate designs, fondant decorations, and extra embellishments can increase the overall size and cost of the cake. Communicate your preferences and budget with your baker to ensure they can create a cake that meets your needs.

In my personal experience attending weddings, I have found that the serving estimates for each tier are generally accurate. However, it’s always better to have some extra cake than to run out, as guests often enjoy having seconds or taking slices home.

To summarize, a classic three-tier wedding cake with 12, 10, and 8-inch layers can serve approximately 100 people. However, it is crucial to consider the serving size and preferences of your guests. Adding additional sheet cakes or cupcakes can provide extra servings if needed. Communicate your needs and budget with your baker to create a cake that suits your wedding perfectly.
