How Many People Does a 6-Inch Cake Feed?

A 6-inch round cake serves about 12 slices, party or wedding cut, as a two-layer cake about 4 inches tall — the published Wilton chart figures. As a single 2-inch layer it serves about half: 6 slices.

6-inch round cake serves

Two layers, about 4 in tall: 12 party (1½ × 2 in slice) · 12 wedding (1 × 2 in slice). Single 2-inch layer: about 6 party · 6 wedding (Wilton: under 3 in yields half).

Data & method: Serving counts from the published Wilton cake serving chart (two-layer cakes about 4 in tall; party 1½ × 2 in slice, wedding 1 × 2 in slice). Single-layer figures apply Wilton's rule that cakes under 3 in tall yield half (rounded down). The calculations are covered by automated tests. How we calculate →

A 6" round seats about 12 party servings — enough for 12.

6-inch round cake servings: two layers vs. one

Serving counts come down to slice size. Cut party-style (1½ × 2 in slice), a two-layer 6-inch round yields about 12 servings; cut wedding-style (1 × 2 in slice) it still yields 12 — on a cake this small the two cuts converge. Wilton's figures hold for any cake 3 to 6 inches tall in this pan: height doesn't add servings, because the cake is cut the same way across the top — a taller cake just gives taller slices. A cake under 3 inches tall, such as one 2-inch layer, yields about half: 6 party or 6 wedding.

Same width, different shape: the 6" square serves 12 party / 18 wedding. The corners matter most in slim wedding cuts — cut wedding-style, a square out-serves the round of the same width on every chart size; party counts run closer and sometimes tie.

Frequently Asked Questions

How many people does a 6-inch round cake feed?

As a two-layer cake about 4 inches tall, a 6-inch round feeds about 12 people with party slices (1½ × 2 in slice) or 12 with wedding slices (1 × 2 in slice) — the published Wilton serving-chart figures. Baked as a single 2-inch layer it feeds about half: 6 party or 6 wedding, because Wilton says cakes under 3 inches tall yield half the servings.

How many wedding servings is a 6-inch round cake?

12 — the same as its party count. On a cake this small the two cutting patterns converge, so the Wilton chart lists 12 either way (about 6 as a single 2-inch layer).

Is a 6-inch round cake enough for 17 people?

Cut party-size, no — a two-layer one seats about 12. Add a small second tier or go one size up — slimmer slices don't add servings at this size. Rounding up beats running short: end pieces and uneven cuts always eat into the chart number.

Does a taller cake serve more people?

The Wilton chart is written for a two-layer cake about 4 inches tall, and Wilton says cakes 3 to 6 inches tall in the same pan yield the same number of servings, because they're cut the same way — a taller cake gives taller slices, not more of them. A cake under 3 inches tall (one 2-inch layer) yields about half: 6 party or 6 wedding slices for a 6-inch round.
