Last Updated on December 16, 2022

If you have ever been to a bakery, you likely know what a half-sheet cake size is and have probably had one at a celebration before. It is a popular choice for birthday parties, graduations, baby showers, or any special occasion. Since they are popular for celebrating special occasions, they can be beautifully decorated with custom text added to them.

Bakeries and grocery stores generally sell half-sheet cakes for special orders. Some places will even have pre-made cakes ready to purchase to which you can add text. Before you order a half-sheet cake, you should know what size it is so you can make sure you have enough cake.

What is a Half Sheet Cake?

A half-sheet cake is a large rectangular cake that is commonly served for large gatherings of people. It can either be a single or double layer of cake. A double-layer cake is a great way to get more servings out of your cake.

Half Sheet Cake Size

You will most commonly see half-sheet cakes in white, yellow, marble, or chocolate flavors. They are most commonly decorated with delicious buttercream frosting. However, some bakeries offer more flavors of cake and frosting to choose from.

Benefits of a Half Sheet Cake

Though round cakes can be great for small gatherings, half-sheet cakes are often a better choice when you have a larger group of people. With a half-sheet cake, it is much easier to cut equal slices of cake thanks to its large rectangular size. The slices will also be neater and easier to serve.

How Big is a Half Sheet Cake Size?

A half-sheet cake size can vary depending on where you get it from. When you get a half-sheet cake from a bakery, it is generally either 15 inches by 11 inches, 15 1/2 inches by 10 1/2 inches or even as big as 16 inches by 12 inches. Since home ovens are smaller than bakery or grocery store ovens, a home half sheet cake will likely measure 13 inches by 9 inches.

Depending on how you slice it, a half-sheet cake will likely serve between 18 to 40 people. A double-layer half-sheet cake will allow you to get larger pieces, so it is a good option if you are serving a larger amount of people.

Full Sheet and Quarter Sheet Cakes

In addition to a half, sheet cakes also come in full and quarter sizes. Most homemade sheet cake recipes are quarter sheet cakes, as full sheet cakes generally do not fit in most home ovens.

A full-sheet cake is ideal for big gatherings of people, such as corporate events and large parties. They generally measure 18 inches by 24 inches. A full sheet cake will typically serve 64 to 96 people.

Half Sheet Cake

Quarter sheets cakes are great for smaller gatherings, like birthday parties and barbecues. A quarter sheet cake typically measures 13 inches by 9 inches. It will generally serve 16 to 24 people.

Making Your Own Half Sheet Cakes

If you want to save a trip to the grocery store or bakery, you can make your half-sheet cakes at home. You can either use sheet cake recipes, that call for a 13-inch by 9-inch pan, or use cake mix.

If you use a boxed cake mix to make a half-sheet cake, you will need three boxes of cake mix. For the two-layer cake, you’ll need six boxes of cake mix and two 13-inch by 9-inch pans. It is always best to cook layer cakes at the same time so they both get an even bake.

Decorating

One of the great things about half sheet cake is that there is plenty of room to decorate and personalize it. Buttercream is generally the most common frosting to use as it tastes great and is easy to work with. If you are frosting your half-sheet cake, you will likely need six cups of frosting for a single layer and 8-10 cups for a double-layer cake.

For adding words, it is generally recommended to use a #2 piping tip. This will create elegant lettering, without the words looking bulky. A #21 piping tip is recommended for frosting borders and #127, 122 and 349 piping tips are great for making flowers.

If you don’t feel confident in your piping skills, cake stencils are a great alternative for creating elegant designs. Cake stencils can be easy to use and you can create many different beautiful designs with them. They can also be reused which is great too.
