The quick and easy answer is 12 servings of a dessert or 8-9 servings of a savory casserole. A 9×13 is 3 quarts or 12 cups. Using a 1 cup serving size.

This is the most common size casserole dish for creating large recipes. Especially when you have a group of people that you need to make party-size servings for.

Keep reading to find out more about just how many people that rectangular pan can feed. And if you need to think about doubling your original recipe size.

How Many Servings In A 9 By 13 Inch Pan? 

Figuring out the number of servings in a 9×13 baking dish may seem cut and dry. But there can be some variation based on the standard size of your servings.

If you have big eaters with larger appetites, you may only be able to get around 12 individual portions from a larger pan.

If you have a group with smaller appetites, the typical serving size may allow you to have 20 servings. This is based on the size of your larger casserole dish. Perfect for side dishes!

Small portions are usually the perfect size if you’re serving a full sheet cake or a dessert. While the medium-sized portions can be reserved for main dishes. This way you can make sure each guest gets as much lasagna as they want.

Should I Plan On A Different Number Of Servings Based On What I’m Making? 

What you’re making in a dish is just as important as the size of a baking pan. Because there will be a major difference in the perfect size to serve.

For example, a general rule of thumb is to plan the pan having more servings for a double-layer cake than a single-layer cake. This is because the density of the dish will often make guests take smaller slices.

Sheet cake sizes will tend to have large slices. Based on sheet pans being more shallow than a square pan, or the round pans traditionally used for baking. 

If you’re making something other than homemade cake recipes in your large rectangle pan (9×13), the serving sizes are going to vary.

The 117 square inches of surface area in these pans holds 12 servings for dishes like lasagna or sliders. But another popular use for these dishes is to make casserole.

When it comes to knowing how much food you have for your guests, it’s always better to underestimate. Assume the serving size is bigger than it ends up being, rather than not having enough.

Cake Pan Servings

With so many different sheet cake pan sizes, how can you know which type of pan to use? The best way of figuring it out is to choose based on how much cake you want to make.

Also, the bake time that you have, and how many cups of batter that you’ve whipped up.

Below I’m going to be going through the different sheet cake sizes. Perfect for knowing how many cake servings you can get from each one. 

  • Rectangular cake – A single layer full sheet cake created in this size pan can be cut in different ways to create either 12, 15, or 20 single cake slices. This is one of the best sheet cake pans for when you want to serve a lot of people, so that you can make sure you have as much food as you need. You can also start with cutting up a half sheet pan, and then base the remaining sections on how quickly or slowly those pieces go. 
  • Square pan – This size of pan is best for smaller parties, with the most common cake pan size being 8 or 9 inches. Based on the size of the cake, you traditionally can get 9 to 15 slices from a square cake. 
  • Round panA round pan is usually around the same size as a square pan, but because of the rounded edges, you may get less servings. The cake serving size of a round cake is 8 to 10 slices for a single-layer cake. If you have multiple layers of cake, you may get closer to 12 to 16. 
  • Loaf pans – A loaf pan is usually a thin, deep pan for baking things like banana bread or a very small size cake. The cake serving size is generally 7 slices. 
  • Tube pan or 12-cup bundt pan – The pan area for these is typically 10 or 12 inches in diameter. Depending on if you’re using a 10-cup pan or 12-cup pan, you will usually be able to get around 12 slices.

When planning what size pan that you need to serve all of your guests, it’s important to make sure that you make the right choice. I always recommend overestimating and choosing a pan bigger than you think that you need.

At the end of the party, it’s better to be left with a half sheet cake that you can send home with guests. You don’t wan to run out when you realize that you didn’t make enough, so keep this in mind when trying to decide on the right pan size for your recipe.
