Cake Serving
Plan servings for a round cake by diameter and layers.
About Cake Serving
Serving counts scale from an 8-inch, two-layer baseline that serves roughly eleven, adjusted by area and layer count. Cake portions vary widely, so giving several cut styles keeps you from over-baking or running short at a party.
Formula
Cake Serving
Servings scale by (diameter / 8)^2 x (layers / 2), relative to a standard 8-inch two-layer cake

Assumptions and limits
- The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to whole numbers, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
