Wedding Cake Calculator

For 100 guests, a 3-tier cake with 6", 10", and 14" rounds yields 128 wedding-slice servings. The standard wedding slice is 1"×2"×4" — about half the size of a birthday slice. Plan to add 8-12 servings if you're saving the top tier for your first anniversary. Wedding cakes typically cost $4-15 per slice depending on complexity.
