Industry Wilton Serving Matrix
A standard wedding cake slice measures 1 inch wide × 2 inches deep × 4 inches high. Round tier serving yields: 6" = 12 servings; 8" = 24 servings; 10" = 38 servings; 12" = 56 servings; 14" = 78 servings. If an alternate dessert table is present, reduce cake portions by 20% to 25%.

Common Questions About Cake Calculator
What is the "Kitchen Sheet Cake" secret?
You order a modest, beautifully decorated 2-tier cake (6" + 8") for your cutting ceremony and photos, while your catering staff cuts unadorned frosted sheet cakes of the exact same flavor in the kitchen to serve guests. This saves $400–$700 without sacrificing taste.
Do we need a cake slice for every single invited guest?
No. If you have an additional dessert table, late-night snack, or sweet table, roughly 20% to 25% of guests will skip cake entirely. Ordering cake for 75% to 80% of your guest list prevents food waste.
Do couples still freeze the top tier for their first anniversary?
While tradition says to freeze the top tier, many couples prefer to eat it fresh during the wedding week or have their baker make an identical fresh mini-cake on their first anniversary for $30.
