How Many People Does a 16-Inch Round Cake Feed?

A 16-inch round cake serves about 77 party or 100 wedding slices — the published Wilton chart figures.

77 party (1½ × 2 in slice) · 100 wedding (1 × 2 in slice)

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 →

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

16" round cake servings, both ways to cut

Serving counts come down to slice size. Cut party-style (1½ × 2 in slice), a 16-inch round yields about 77 servings; cut wedding-style (1 × 2 in slice) it stretches to 100. 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 16" square serves 80 party / 128 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 16" round is the chart's answer for 75 guests cut party-size.
