Wedding Cake Size Calculator
How big should your wedding cake be? Enter your guest count and we'll recommend tier diameters and total servings using bakery-standard 1" x 2" wedding-portion cuts.
| Tier (bottom to top) | Diameter | Servings |
|---|---|---|
| Tier 1 | 12" | 56 |
| Tier 2 | 10" | 38 |
| Tier 3 | 8" | 24 |
| Tier 4 | 6" | 12 |
Servings assume bakery-standard 1" × 2" wedding-portion slices. For dessert-bar weddings where cake isn't the main sweet, reduce by 20-30%.

Frequently asked
How many tiers do I need?
+
Up to 50 guests: 2 tiers. 50-100: 3 tiers. 100-200: 4 tiers. 200+: 5 tiers or a sheet cake backstage.
Do I need cake for every guest?
+
Plan for one slice per guest. About 60-70% will eat it, but cutting short causes more upset than leftover cake.
What's a 'kitchen' or 'backstage' cake?
+
A sheet cake hidden in the kitchen and cut to extend the decorative tiered cake. Common for 200+ guest weddings to reduce overall cake cost.
