How Many People Does a 6-Inch Round Cake Feed?

A 6-inch round cake serves about 12 party or 12 wedding slices — the published Wilton chart figures.

Data & method: Serving counts from the published Wilton cake serving chart (4-inch-tall cakes; party 1½ × 2 in slice, wedding 1 × 2 in slice). Every figure is checked by an automated test. How we calculate →

We'll find the smallest cake that seats them, using the party/wedding slice size selected above.

A 2-tier round (14" + 12") seats about 103 party servings — enough for 100.

6" round cake servings, both ways to cut

Serving counts come down to slice size. Cut party-style (1½ × 2 in slice), a 6-inch round yields about 12 servings; cut wedding-style (1 × 2 in slice) it stretches to 12. Both figures assume the classic 4-inch-tall, two-layer cake the Wilton chart is written for — bake it as a taller three- or four-layer cake and it serves roughly half again as many.

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.

All round sizes compared

Size Party (1½ × 2 in slice) Wedding (1 × 2 in slice)
6" round 12 12
8" round 20 24
9" round 24 32
10" round 28 38
12" round 40 56
14" round 63 78
16" round 77 100

Planning from a head count instead? The 6" round is the chart's answer for 10 guests cut party-size.

Frequently Asked Questions

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

A 6-inch round cake feeds about 12 people with party slices (1½ × 2 in slice) or 12 with wedding slices (1 × 2 in slice). These are the published Wilton serving-chart figures for a standard 4-inch-tall, two-layer cake — the reference most bakeries plan with.

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.

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

Cut party-size, no — it 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.

How tall is the cake these numbers assume?

The Wilton chart assumes a 4-inch-tall, two-layer cake. A modern three- or four-layer cake running 6 inches tall serves roughly 50% more, because each slice is taller — if you bake tall, you can size down a tier.
