Overall, the depth of a quarter sheet cake depends on the sheet cake pan length and recipe.

Dimensions and shape of a quarter sheet cake

Typically, a quarter sheet cake measures approximately 9 x 13 inches. However, the length and width may vary depending on the recipe or sheet cake pan length.

As far as the shape is concerned, a quarter sheet cake is always a rectangle with straight or rounded edges. The best part about its shape is it’s always easier to cut and distribute the slices evenly.

Calculation of the number of servings of a quarter sheet cake

It’s crucial to take both the size of the cake and the serving size into account when estimating how many servings a quarter sheet cake may provide. A common formula for determining the number of servings that works every time is:

  1. Calculate the serving size: A sheet cake’s normal serving size is 2 by 2 inches (5 by 5 cm). However, you may change the size according to your taste or the situation.
  2. Calculate the area: You must calculate the cake’s area to ascertain the total number of servings. To calculate the cake’s total square inches (or square centimeters), multiply the cake’s length by width in inches (or centimeters). The area would be 117 square inches, for instance, if the quarter sheet cake is 9 x 13 inches.
  3. Divide: Divide the whole area of the cake by the area of each dish. This will then provide you with a ballpark figure for servings. If each serving is 2 × 2 inches (4 square inches), then 117 square inches would be divided by 4 square inches to produce about 29 servings.

And this is how in 3 easy steps you can calculate the number of servings of a quarter sheet cake.

How to make a perfect quarter sheet cake that tastes delish

A sheet cake is a party staple that people love. Here is an easy way to make it the right way.

Prepare sheet cake pans

Use a cooking spray or grease the sheet pan to ensure easy release of the cake. You can also line the sheet pan with parchment paper. I always advise using a cake pan with straight sides so the cake bakes evenly.

Measure and mix properly

Needless to say, if you want to bake a perfect full half-and-quarter cake, the key is accurate measurements and mixing of the ingredients.

Therefore, I suggest using a proper kitchen scale or measuring cups for precision. Avoid overmixing at all costs as it may result in a tough cake, while undermixing can lead to uneven texture. So, you have to be precise when it comes to mixing.

Temperature and baking time

Always preheat your oven to the recommended time in the recipe and place the sheet cake pans in the center to distribute heat evenly.

Turn the time clock on, and keep an eye on the time. Use a toothpick to check for cake doneness.


After the cake is baked and done, allow it to cool down completely at room temperature. Here’s some tips on how to keep your delicious cake fresh for as long as possible.

Frosting and decorating

Make sure the cake is cooled completely before you apply frosting or decorations, and add whatever you wish to add to the cake.
