7x11 cake servings: two layers vs. one
Serving counts come down to slice size. Cut party-style (1½ × 2 in slice), a two-layer 7x11 sheet yields about 24 servings; cut wedding-style (1 × 2 in slice) it stretches to 32. 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: 12 party or 16 wedding.
All sheet sizes compared
| Size | Party (1½ × 2 in slice), two layers | Wedding (1 × 2 in slice), two layers | Single 2-in layer (party / wedding) |
|---|---|---|---|
| 7×11" sheet | 24 | 32 | 12 / 16 |
| 9×13" sheet | 36 | 50 | 18 / 25 |
| 11×15" sheet | 54 | 74 | 27 / 37 |
| 12×18" sheet | 72 | 98 | 36 / 49 |
Two-layer columns: the Wilton chart (cakes 3–6 in tall serve the same). Single-layer column: Wilton's rule that cakes under 3 in tall yield half, rounded down.
Cutting a single-layer 7x11 into squares
Single-layer sheets are often cut into squares rather than Wilton's slices — WebstaurantStore calls 2 × 2 and 2 × 3-inch pieces typical. Here is how many whole pieces of each size fit a 7x11 cut in a straight grid — plain arithmetic from the pan's dimensions, not a published serving chart, and with no edges trimmed:
- 2 × 2 in pieces: 15
- 2 × 3 in pieces: 10
- 3 × 3 in pieces: 6
Ordering from a bakery, or wondering whether this is a "quarter" or "half" sheet? Names vary by bakery — see the sheet cake sizes and servings guide.
Planning from a head count instead? As a two-layer cake, the 7×11" sheet is the chart's answer for 10 people and 15 people and 20 people cut party-size.
