  1. Party slice area = 3 sq in. 8" round surface area = 50.3 sq in.
  2. Party servings = 12 to 14 portions.
  3. Wedding slice area = 2 sq in. Wedding servings = 20 to 24 portions.
Result: An 8-inch cake serves 14 party guests or 24 wedding guests.

Common Kitchen Mistakes to Avoid

Cutting round cakes only in wedges

For round cakes 8" and larger, cutting concentric circles before slicing yields 40% more even portions.
