While it’s tempting to buy extra cake, studies show most groups consume 1–1.5 slices per person. For a crowd of 20, 20–30 slices are usually sufficient—a perfect-sized 9x13 inch or two smaller tassels.

Fact 2: Event Type Determines Presentation

  • Check standard dimensions: Most cupcake tins hold exactly 1.9 inches and yield 3–4 slices.
  • Consider appetites and time: Larger cakes need reheating and decoration time—plan accordingly.
  • Mix and match: Combine mini blocs with an elegant 8-inch tier for an elegant yet balanced presentation.
