Wedding Cake Serving & Tier Calculator — frequently asked questions
How does this wedding cake calculator estimate servings?+
It starts with your guest count, adds a serving buffer, splits servings between display tiers and optional sheet cake, then chooses the smallest tier stack that covers the display-cake target.
What portion styles are included?+
The calculator includes traditional wedding slices, larger party slices, and generous dessert portions. Larger portions reduce the estimated servings available from the same tier sizes.
Can I include sheet cake behind the scenes?+
Yes. Free users can choose no sheet cake, a light backup, or a standard backup. Pro unlocks a custom sheet-cake percentage and editable sheet-cake serving and cost assumptions.
Is my wedding plan sent to a server?+
No. Guest count, tier sizes, sheet-cake backup, serving buffers, and cost estimates are calculated entirely in your browser.
