How many people does a 10-inch round cake serve?

A 10-inch round cake typically serves 20-25 people with standard party-sized slices (2" × 4"), 15-20 people with generous dessert portions (3" × 4"), or 35-40 people with small wedding-style portions (2" × 2").

Should I order extra cake for my event?

It's generally recommended to have 5-10% extra servings, especially for important events. Not everyone will eat cake, but it's better to have leftovers than run short. Consider your guests' preferences and the presence of other desserts.

How do I cut a round cake into equal portions?

For round cakes, start by cutting the cake in half, then quarters, then eighths. For more servings, cut each wedge in half again. Use a long, sharp knife and clean it between cuts for neat slices.

What's the difference between wedding and party serving sizes?

Wedding servings are typically smaller (2" × 2") because guests often have a full meal beforehand and multiple dessert options. Party servings are larger (2" × 4") as cake might be the main dessert or served with lighter refreshments.

How do multiple layers affect serving calculations?

Each layer effectively doubles the cake area, so a 2-layer cake serves twice as many people as a single layer of the same size. Our calculator automatically accounts for multiple layers in the serving count.

Can I use this calculator for sheet cakes?

Yes! Use the rectangular option for sheet cakes. A full sheet cake (18" × 24") typically serves 96 people with standard portions, while a half sheet (12" × 18") serves about 48 people.
