Custom Cake Size Guide: How Much Cake Do You Need?
A general serving-size guide to help you choose the right cake size for your guest count.
Updated June 22, 2026
Cake sizing is based on standard serving sizes (roughly 1 inch by 2 inch slices), but actual portions vary by cake artist. Use this as a general starting point.
Rough Serving Guide
- 6-inch round: 8-12 servings
- 8-inch round: 16-24 servings
- 10-inch round: 24-38 servings
- Two-tier (6" + 10"): 30-45 servings
- Three-tier (6" + 8" + 10"): 55-75 servings
If your guest count falls between sizes, tell the cake artist directly. A business from the Orlando baker directory can recommend a display cake and sheet cake combination.
