Tier yields use Wilton's 4-inch-high round-cake wedding chart. Confirm every yield and cutting pattern with your baker before ordering.

Use an event-specific RSVP or caterer estimate. The reduced settings are optional scenarios, not published participation rates.
This is an editable planning allowance, not an evidence-based recommendation.
Uses Wilton's published yield for that slice style on every display tier and kitchen sheet cake.
The calculator substitutes Wilton's matching published party yield when larger slices are selected.
Use the baker's current all-in quote when possible.

What this wedding cake estimate assumes

The calculator keeps ceremonial tiers, cutting yield, backup cake, and price visible instead of hiding them in one guest-count rule.

  • Wilton's chart gives 12, 24, 38, 56, and 78 wedding servings and 12, 20, 28, 40, and 63 party servings for 6-, 8-, 10-, 12-, and 14-inch round tiers that are 3 to 6 inches high.
  • Wedding chart slices are about 1 × 2 inches; party slices are about 1.5 × 2 inches. The calculator sums Wilton's published yield for each selected tier and uses the matching published yield for each sheet-cake size.
  • The 70%, 85%, 5%, and 10% settings are optional editorial planning scenarios, not evidence-based participation or cushion rates. Replace them with event-specific information from RSVPs, your baker, or your caterer.
  • Saving a 6-inch top tier removes its 12 published servings in either slice style.
  • Kitchen sheet cakes cover only the shortfall in the same selected slice unit and round up to whole cakes. Confirm sheet dimensions, height, slice size, and promised yield because bakery naming is not universal.
