Figuring out how much cake you need for a party is not as complicated as learning calculus was in high school. (Remember how much fun that was?). Still, it can be tricky.

For one thing, there’s no predicting how hungry for cake your guests will be.  Plus, “serving size” is a highly subjective term: One person’s “slice” is another person’s “sliver.” 

For our estimates we use Party Size servings, Wedding size servings are 1 inch by 1 inch.

Still, you really don't want to run the risk of not having enough cake to go around (the horror!)

Here are some good estimates that will help you figure out how to size your cake, based on average portions per pan.
