Cake Serving Calculator
Count how many people a cake or tiered wedding cake serves, and price it per slice.
About the Cake Serving Calculator
Serving counts follow the widely used Wilton charts for 4-inch-tall tiers: party slices are about 1.5 × 2 in and wedding slices 1 × 2 in, so the same cake serves more at a wedding. Enter one pan code per tier, for example r10, r8 and r6 for a 10-8-6 inch round cake (94 wedding servings).
The formula
Total servings = Σ servings per tier
