Cake Servings Calculator
Calculate how many servings you can get from a cake based on its shape and dimensions.
Estimated Servings
Cake servings depend on the shape, dimensions, and how you cut the slices.
Standard serving size: A party serving is typically 1" × 2" × 4" (2.5 × 5 × 10 cm) — about the size of a deck of cards.
Round cakes (by diameter):
| Diameter | Servings (party) | Servings (wedding) |
|---|---|---|
| 6 in (15 cm) | 12 | 8 |
| 8 in (20 cm) | 20 | 14 |
| 10 in (25 cm) | 28 | 20 |
| 12 in (30 cm) | 40 | 28 |
| 14 in (36 cm) | 56 | 40 |
Square cakes yield about 25% more servings than rounds of the same dimension.
Sheet cakes:
- Quarter sheet (9×13 in): 18–24 servings
- Half sheet (12×18 in): 36–48 servings
- Full sheet (18×24 in): 72–96 servings
Tips:
- Wedding-style slices are thinner (1" × 2" × 3")
- Layer cakes (3+ inches tall) can be cut into more servings
- Always cut from the center for even slices
