Standard Cake Sizes and Portions
Here's a simple breakdown of how many servings each cake size can provide:
6-inch Cake – Feeds around 6–8 people. Perfect for small family birthdays or intimate gatherings.
8-inch Cake – Feeds 10–14 people. A popular size for standard birthdays or small parties.
10-inch Cake – Feeds 20–25 people. Ideal for larger family events or milestone birthdays.
12-inch Cake – Feeds 30–40 people. Works well for weddings, engagements, or community celebrations.
Two-Tier Cakes – Feeds 40+ people depending on size combinations, great for weddings and big occasions.

Square vs Round Portions
Did you know? Square cakes serve more people than round cakes of the same size. That's because square cakes give more edge-to-edge surface area, meaning you can cut them into more uniform slices.
Check out our Drip Birthday Cake (available in both shapes).
Portion Sizes for Weddings vs Parties
Weddings – Wedding slices are traditionally smaller (1" x 2"), as the cake is usually served alongside other desserts. This means a cake can stretch to serve more people.
Birthday Parties – Birthday slices are typically larger (2" x 2" or more), especially for kids' parties where cake is the star of the show.
