11×15" sheet cake servings, both ways to cut

Serving counts come down to slice size. Cut party-style (1½ × 2 in slice), a 11×15-inch sheet yields about 54 servings; cut wedding-style (1 × 2 in slice) it stretches to 74. 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.

Planning from a head count instead? The 11×15" sheet is the chart's answer for 40 guests and 50 guests cut party-size.

Frequently Asked Questions

How many people does a 11×15-inch sheet cake feed?

A 11×15-inch sheet cake feeds about 54 people with party slices (1½ × 2 in slice) or 74 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 11×15-inch sheet cake?

74 wedding servings. Wedding slices are cut slimmer (1 × 2 in slice versus 1½ × 2 in slice for party slices), so the same cake stretches 20 servings further than at a party.

Is a 11×15-inch sheet cake enough for 59 people?

Cut party-size, no — it seats about 54. Either cut closer to wedding size (74 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.
