A 12-inch round wedding cake typically serves around 40 to 60 guests, depending on the portion size. If the cake is layered and includes additional tiers, it can serve even more people. The serving size can vary based on the thickness of the slices and the overall design of the cake. For precise serving estimates, consulting with a baker is recommended.
Generally it depends on how deep (how many layers) your cake is. Standard serving size of a piece of cake is 1" x 2". Also depending on how large you want to cut your slices (sensible vs generous), a 7" round cake can serve anywhere from 6-10 people.
