Party Planning Tips
• Order 5-10% extra servings to account for varying slice sizes
• Wedding cakes typically use smaller slice sizes (1.5-2 sq in)
• Birthday parties often use standard slices (2-3 sq in)
• Consider guest demographics - children often prefer smaller slices
Example Calculation
Wedding for 100 Guests
Guests: 100 people
Cake Shape: Round

Recommendation
Option 1: Single 16" round cake (201 sq in)
Option 2: Two-tier cake (11" + 13" = ~254 sq in)
Servings: 100-127 portions

Understanding Cake Serving Calculations
How Cake Serving Works
Cake serving calculations are based on the total surface area of the cake divided by the desired slice size. This method ensures consistent portion sizes and helps you order the right amount of cake for your event.
Factors to Consider
- •Number of guests attending
- •Type of event (wedding, birthday, casual)
- •Other desserts being served
- •Guest demographics and preferences
Calculation Method
Required Area = Guests × Slice Size
Servings = Cake Area ÷ Slice Size
Area Calculations
- Round Cake: π × (diameter ÷ 2)²
- Square Cake: side × side
- Rectangle Cake: length × width
Pro Tip: Order 5-10% extra to account for uneven slicing and ensure everyone gets served.
