9×13" sheet cake servings, both ways to cut

Serving counts come down to slice size. Cut party-style (1½ × 2 in slice), a 9×13-inch sheet yields about 36 servings; cut wedding-style (1 × 2 in slice) it stretches to 50. 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.

Frequently Asked Questions

How many people does a 9×13-inch sheet cake feed?

A 9×13-inch sheet cake feeds about 36 people with party slices (1½ × 2 in slice) or 50 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 9×13-inch sheet cake?

50 wedding servings. Wedding slices are cut slimmer (1 × 2 in slice versus 1½ × 2 in slice for party slices), so the same cake stretches 14 servings further than at a party.

Is a 9×13-inch sheet cake enough for 41 people?

Cut party-size, no — it seats about 36. Either cut closer to wedding size (50 slimmer slices), add a small second tier, or go one size up. 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.
