How Big Is A Quarter Sheet Cake?

If you’re entertaining a large group of guests, there’s few better things you can bring to the table than a delicious cake.

It’s one of the very best party foods, because you can make them in all different varieties, and each will give you plenty of servings to dish out to your hungry guests.

One of the easiest ways to make a sizable amount of cake is with a sheet pan, because they give you a large rectangular space to bake in.

However, sheet pans come in all different sizes, which means that you can get different sizes of sheet cake.

How Big Is A Quarter Sheet Cake?

It’s essential that you know how big your sheet pan is, so that you know how many servings you’re likely to get from the sheet cake it produces.

So, how big is a quarter sheet cake? 

The short answer is that it varies. The majority of them will be 13 inches by 9 inches, but there are slightly smaller varieties that are 12 inches by 8 inches instead.

Whatever the case, the general idea is that they’re a quarter of the size of a regular sheet cake/pan.

There’s plenty more to learn about quarter sheet cakes, such as how many people you’ll be able to feed from one, and you’ll be able to find all the answers in our fun guide below. Read on!

How Big Is A Quarter Sheet Cake?

As you can guess from the name, a quarter sheet cake is supposed to be a quarter of the size of a regular sheet cake. A sheet cake is as big as its sheet pan, and sheet pans are large and rectangular in shape.

Most sheet cakes that you get will measure 13 inches in length and 9 inches in width, and their depth is typically about 1 to 2 inches. 

With that being said, you’ll come across sheet cakes/pans that are a little bit smaller than this. These ones will be 12 inches in length and 8 inches in width, but likely the same depth.

How Many Servings Will You Get From A Quarter Sheet Cake?

If you’re baking a quarter sheet cake using a typical quarter sheet pan, then you’re likely to get 12 servings of cake. These servings will be about 3 inches in length and 3 inches in width, which is a good size.

As an aside, the quarter sheet cake will often weigh about 75 ounces.

How Many People Can A Quarter Sheet Cake Feed?

Since a typical quarter sheet cake will give you 12 servings, this means that the cake should be able to feed 12 people.

If there is only one slice per person, then everyone should be able to have an equal share of the tasty treat.

This means that if you’ve got a party for 12 people, then you’re going to be sorted. But what if your party is bigger than that?

How To Get More Servings Out Of A Quarter Sheet Cake

As you can guess, the way to get more servings out of a quarter sheet cake is by cutting much smaller slices.

We calculated 12 servings on the basis that each one was 3X3 inches, but if you make smaller slices then there will be more to go around, without having to bake any extra cake.

For this reason, if you’re feeding 18 guests, then you can cut the quarter sheet cake into 18 slices, each measuring about 2X3 inches.

Similarly, when you’re trying to feed 24 people, then make each slice measure 2 inches in length and 2 inches in width.

If your party is really massive, and you’re going to feed 54 hungry mouths, then you can cut a single quarter sheet cake into 54 servings.

However, each of these are only going to measure roughly 1X2 inches, which is admittedly quite small.

If you’re trying to feed this many guests with one sheet cake, then it might be a better idea to use a half sheet pan instead – or even a full sheet pan.

How Big Is A Half Sheet And A Full Sheet Pan?

Speaking of using bigger sheet pans to cater to more guests, it’s important to look at how big half sheet pans and full sheet pans are. 

A typical half sheet pan will measure 18 inches in length and 13 inches in width.

A full sheet pan, on the other hand, will usually be 26 inches long and 18 inches wide.

How Can You Measure Your Quarter Sheet Pan?

Although the majority of quarter sheet pans are one uniform size, we’ve already discussed the fact that some are slightly smaller.

Since size is a very important factor in determining how many servings you’re going to get (or, at least, how large they will be), you’ll need to know the exact measurements of your particular pan.

So how do you measure one?

Well, there are two methods. The easiest one is to use a tape measure, which will allow you to take note of all the different measurements.

Using the tape, you can measure the length of the pan, the width across it, and then the depth from the top to the bottom.

With these figures to hand, you’ll be able to account for the size of your sheet cakes, and know how easily you can divide up the servings.

The other method involves measuring the pan’s volume content, which you can do with water. This is because a typical quarter sheet pan will hold as many as 12 cups of water.

Therefore, repeatedly fill up your clean pan with cups of water, making sure not to overfill it. If it can hold 12, then you’ll know it has the measurements of a regular quarter sheet pan.

Final Thoughts

A quarter sheet pan will usually measure around 13 inches in length, 9 inches in width, and 1-2 inches in depth. This means that a quarter sheet cake is about the same.
