How Many Slices in a 10-inch Cake?

Who can turn down a piece of cake? Well, after your third serving, perhaps it’s best to leave some cake for the others.

The thing about cakes is that they come in a wide assortment of sizes and shapes. While paying attention to the ingredients that go into your cake is important, what’s even more important is that there’s enough cake to go around.

In today’s guide, I’ll briefly cover how large a 10-inch cake is and how many slices you can get out of it.

10-Inch Round Cake

10-Inch Round Cake

A 10-inch round cake mold can vary in height. Some pans are as shallow as 2 inches, while others are 5 inches and beyond. For the sake of simplicity, I’m going to focus on 10-inch round cake pans that measure 4 inches in depth.

This is a decent-sized cake pan for large parties or for a Tuesday night. It can comfortably serve at least 10 people, but it ultimately depends on how many cuts you make.

How Many Slices Can You Get from a 10-inch Cake?

How Many Slices Can You Get from a 10-inch Cake?

Unlike a 7-inch cake, if you’re working with a 10-inch round cake, you can easily divide it into 12 to 16 slices, depending on how generous you are.

As is typical with any cake mold, make sure you leave at least 1 inch from the top when pouring your cake batter in. That way, the batter will have room to rise and not go over the top like it would in a muffin tray.

When pouring the batter into a 10 × 4-inch cake pan, you’ll only need to prepare 10 × 3 inches of batter. To calculate how much batter this is, take the radius of the cake pan (diameter ÷ 2), square it, then multiply it by pi. For the sake of simplicity, we’re going to use 3.14 in place of pi.

So, you will only need to prepare roughly 235.5 cubic inches (3.14 × 55 × 3) of batter.

As the cake bakes, it’ll rise to about the brim of the cake mold, producing an even 10 × 4-inch cake. Overall, you should have 314 cubic inches of cake to go around.

How Much Cake Per Slice?

As I stated earlier, you can divide a 10-inch round cake into 12 to 16 slices. So, if a 10-inch-round cake contains 314 cubic inches of cake, that means each portion will contain 26.167 to 19.625 cubic inches of cake.

If you think that’s too much, feel free to cut the cakes into smaller portions. If you’re like me and could use more cake with each serving, divide the cake into 8 or 10 slices instead.

Dividing the 10 × 4-inch round cake into 8 to 10 pieces will leave each portion with 31.4 to 39.25 cubic inches of cake, which is great as an after-dinner dessert with a small group of close friends.


Overall, a 10-inch round cake is a substantial amount for most situations, such as office parties, small family gatherings, or a regular night like any other. You can cut it into 12 to 16 pieces, but if you want more cake per serving, 8 to 10 slices should be more than generous.

If you think fewer slices of a 10-inch-round cake is ideal, share this guide with your loved ones. If you’re more of a 12- to 16-slice kind of person, drop a comment below and explain why less is more.
