Cakes come in so many shapes and sizes that it can be hard to figure out what works best for you! This handy guide covers our most common, popular sizes. Please bear in mind that everyone cuts servings differently, so it's difficult to specify just how many slices each cake will serve. This is only to give you a basic framework to work with but we hope it helps!

Number of Servings per Sheet Cake

When determining how many servings you can get from your sheet cake, first decide how large you want each piece. Typically, 2” x 2” or 2” x 3” pieces are suitable sizes for each portion. Then, you calculate the number of servings per sheet cake by dividing the pan area by the cake serving size area.

Follow the formula below to determine how many servings yield from a given pan.

# of Servings=Pan Area÷Cake Serving Size Area

• Pan Area = Pan Length x Pan Width
• Cake Serving Size Area = Piece of Cake Length x Piece of Cake Width
