How big birthday cake to feed 50 people?

To determine the appropriate size of a birthday cake to feed approximately 50 people, consider several factors such as individual portion size, cake design and density, and whether you plan to serve other dessert options alongside the cake. Here's a general guideline:

12-inch Round Cake: A 12-inch round cake typically yields around 50 slices. If you want to ensure each person gets a generous serving, you could opt for a 14-inch cake, which provides closer to 60 slices.

Sheet Cake: A full-sheet cake, which is approximately 18"x26" in size, can provide around 48 large slices or a greater number of smaller pieces.

Multiple Cakes: Alternatively, you could have multiple smaller cakes or a combination of cake sizes. For instance, you might provide two 10-inch round cakes and a sheet cake, giving you a variety of options for serving different types of cake flavors.

Cake Density and Design: Consider the density and design of your cake as well. A dense, multi-layered cake will yield more slices compared to a lighter, fluffy cake. Additionally, if your cake has elaborate decorations or a heavy filling, you may want to err on the side of caution and provide a larger cake.

Serving Other Desserts: If you plan to serve other desserts such as ice cream or pie, you may not need as much cake. In this case, a 10-inch round cake or a smaller sheet cake could suffice.

Individual Preferences: Take into account the preferences of your guests when estimating how much cake to provide. If you know a large portion of your guests are avid dessert enthusiasts, you may want to provide more cake.

Remember, this is just a general guide, and the exact cake size also depends on how large you cut your slices. For a formal or elaborate event, providing more cake is always better to ensure everyone can enjoy a sweet treat.
