Last Updated on December 16, 2022

Round cakes are one of the most popular types of cakes. Knowing the different round cake sizes and servings can help you decide how much cake you need for your event. Round cakes are versatile and are particularly great for birthdays, weddings, and special events.

The great thing about round cakes is you can make so many different flavor combinations with them. They provide a great surface for decorating, whether that is with buttercream frosting, fondant, or even flowers. Whether you are baking your own or purchasing one from a bakery, you will want to know the servings for the different sizes of round cakes.

Benefits Of Serving A Round Cake

Round cakes are a popular choice at formal events not only because they are elegant, but you can make tiers with them. Many wedding cakes are at least two to four tiers, allowing them to serve large crowds.

Each tier is generally made of a round cake that has multiple layers. One round cake will generally have two, three, or four layers. Between each layer is a filling that can consist of frosting, jam, fruit, custard, or mousse.

The outside of the cake is then covered in frosting and the tiers are stacked onto each other. In large cakes, dowels are often used to support the weight of the cake.

The more layers your round cake has, the more servings you can get out of it. Generally, cake servings will be smaller at weddings than they are at parties or small get-togethers. This allows more guests to be fed without having to spend even more money.

Round Cake Sizes And Servings

The most common round cake sizes are 6-inch, 8-inch, 9-inch, 10-inch, and 12-inch. Typically, most round cakes will have two or three layers. For weddings, it’s more common for cakes to have three or four layers.

Before baking or purchasing a cake, it is important to know how many servings you need. From there, you can figure out what size round cake will be the best option for the occasion. You should also consider how many layers the cake will have and how you plan to slice it.

What size is an average round cake

6-Inch round cake

A 6-inch round cake is a great size for a dinner party or a small family get-together. A 6-inch cake will serve around eight people on average. For smaller slices, you can get 12 servings from a 6-inch cake.

8-Inch round cake

An 8-inch round cake is a good size for a birthday party or a smaller party. It will serve around 10-14 people with regular slices. For smaller slices, you can get up to 24 slices, which is more practical for large events.

9-Inch round cake

A 9-inch round cake is another good option for birthday parties or holiday celebrations. In general, a 9-inch round cake will serve 12-16 people. For event-sized slices, it can serve up to 30 people.

10-Inch round cake

A 10-inch round cake is relatively large and is great for more formal events, bridal showers, or baby showers. Typically, a 10-inch round cake will be able to serve about 16-25 people. When sliced event style, it can serve up to 38 people.

12-Inch round cake

A 12-inch round cake is quite large, making it a good option for large family gatherings. It can generally serve around 26 to 32 people. When served event-style, you can get 40 to 56 servings, depending on generous you are with the portion sizes.

Tiered Wedding Cake Servings

When serving cake at a wedding or large formal events, the slices are generally smaller than they are for dinner parties, birthdays, and small events. Typically, round cakes are cut into triangular slices. However, for weddings and special events, they are generally cut into rectangular pieces.

There are a few different ways how this is done. Slices cut using these methods will usually be 1-1 1/2 inches wide. These two methods are generally used for round cakes 10 inches and larger.

One way is to cut a small circle within the round cake about two inches from the edge and slice them into pieces. The outer rim of the cake is then also sliced into pieces, allowing you to get more from your cake. Depending on how large the cake is, another circle may also be cut one or two inches within the first circle.

Another way is to cut your cake into long thin horizontal strips that are about one inch wide. Cut the cake lengthwise using a cutting board to lay the cake flat after cutting. Cut the long section of cake into pieces that are 1-1 1/2 inches long.
