When planning a wedding cake, the most reliable way to estimate how many guests you can serve is to calculate the total edible volume of the cake. Volume accounts for the threeβdimensional shape of each tier, which is far more accurate than simply counting layers or using surface area alone.
Each tier of a traditional wedding cake is wellβapproximated by a cylinder. The volume of a cylinder is given by the classic formula
After summing the volumes of all tiers, you divide the total by the desired serving size (typically 120β―inΒ³, roughly one cup of cake). The result, rounded down, tells you the maximum number of full servings you can safely offer while preserving the cakeβs structural integrity and presentation.
