Your Guide to Cake Sizes and Servings

In order to make your life a little easier, we’ve broken down the most common cake pan sizes and the number of servings you can expect to get from each. From round cakes to sheet cakes, this guide will help you decide what to bake for your next celebration.

There’s something truly special about cake. Whether you’re celebrating a birthday, hosting a backyard cookout, or simply indulging in dessert after dinner, cake has a way of turning any gathering into a memorable celebration. And there’s so much fun to be had when it comes to preparing cake! Like choosing the flavor, baking it up in your kitchen, and adding your personal, decorative touch. However, figuring out how many servings you’ll get from your cake can be a bit more confusing.

So, in order to make your life just a little easier, we’ve broken down the most common cake pan sizes and the number of servings you can expect to get from each. From round layer cakes to classic sheet cakes, this guide will help you decide what to bake for your next celebration.

A Cake Serving Size chart showing how many servings you can get out of different types of cake: Cake Roll: 6 to 8 slices. 6" round cake: 6 to 12 Slices. 8" or 9" square cake: 9 to 16 slices. 8" or 9" round cake: 12 to 16 slices. 10" angel food or bundt cake: 12 to 16 slices. 9x13" sheet cake: 20 to 40 slices.

Round Cakes

When you think of cake, a classic, round layer cake is probably the first thing that comes to mind. Round pans are among the most versatile and popular options, offering multiple layers that look as good as they taste.

If you’re cake is between 3 in. to 6 in. tall, you can expect it to yield…

  1. 6-inch round pan: 5 to 11 servings
  2. 8-inch round pan: 12 to 16 servings
  3. 9-inch round pan: 12 to 16 servings

Expert Tip: An 8-inch, three-layer cake is ideal for birthdays and special occasions. If you’re looking for more decorating space, a two-layer, 9-inch round cake is an excellent choice.

Sheet Cakes

Hosting a large gathering? A classic sheet cake is a crowd-pleaser that yields plenty of servings. Depending on how you slice it, you can expect a 9 x 13-inch pan to yield 15 larger servings or 20 to 40 smaller servings.

Unsure of the total head count for your event? We recommend baking an additional sheet cake, just in case. This way, you have plenty if some unexpected guests drop by or if people want seconds!

Square Cakes

Square pans aren’t just for brownies and blondies, they’re also great for one-layer cakes. An 8-inch or 9-inch square pan will yield about 9 to 16 slices, depending on how you cut it. Its compact size makes it perfect for casual gatherings or weeknight treats.
