How Many People Does a Sheet Cake Feed?

How Many People Does a Sheet Cake Feed

So you’re going to have a party and you want to serve a sheet cake but you aren’t sure how many people a sheet cake will feed. The answer get much simpler if we break the decision down into the two questions you need to answer. First, how big is the sheet cake you’re planning to purchase or bake? Second, how big do you want to make the servings.

Sheet cakes from the bakery come in three basic sizes. There is the 1/4 sheet cake that measures 9 inches by 12 inches. A 1/2 sheet cake measures 11 inches by 15 inches. A full sheet cake measures 18 inches by 24 inches. Notice that the 1/2 sheet cake is neither twice the size of a 1/4 cake or half the size of a full sheet cake. It’s actually only 50% larger than a 1/4 cake.

So how generous do you want to be with the serving size? If you make it too small, some people may sneak a second piece. Who can blame them? If it’s too big, some guests watching their waistlines might be reluctant to take any or you may run out.

The serving size chosen most often by caterers is 2 inches by 3 inches. I personally really like cake and would find that a bit on the small size but it’s certainly not stingy. For a formal dinner where the cake is meant just as one delicious course of a multi-course meal, a 2 inch by 2 inch or even smaller piece might be appropriate.

The chart below should give you a pretty good idea of how many people your sheet cake will feed!

If the actual pan you are using does not exactly match the size of any of those mentioned above, pick the one that’s closest and “fudge it” a bit. And don’t be surprised when after all your work to choose the perfect size pieces is over, some guest will still chop one in half or take 1 1/3 pieces.

If the guests coming to your occasion are going to be mostly men, plan on several “two-piecers”. If they will all be women, plan on several “no thank yous”. Hey, don’t kill the messenger! It’s a fact that more women watch their waistlines and more men indulge.

Oh yeah! Don’t forget to save me a piece!
