How It Works

How to Calculate Party Food

Formulas

Total Appetizers = Guests x Pieces Per Person Total Main = Guests x Serving Weight

Planning Guidelines

  • Appetizer-only party: 10-12 pieces per person
  • Dinner party: 4-6 appetizers + main + sides
  • Main course: 200-280 g per person
  • Side dishes: 150-200 g per person
  • Always prepare 10-15% extra

    • Worked Example

    Plan food for a dinner party with 20 guests.

    guests = 20apps_per_person = 8main_g = 250sides_g = 200
    1. 01Appetizers: 20 x 8 = 160 pieces.
    2. 02Main course: 20 x 250 g = 5000 g = 5 kg.
    3. 03Sides: 20 x 200 g = 4000 g = 4 kg.
    4. 04Total food: 5 + 4 = 9 kg plus 160 appetizer pieces.

    Frequently Asked Questions

    How many appetizers per person?

    For a cocktail party (no dinner): 10-12 pieces. Before dinner: 4-6 pieces. As a light snack: 3-4 pieces.

    Should I prepare for extra guests?

    Yes, plan for 10-15% more food than your headcount. Some guests eat more, and it is better to have leftovers than run short.

    How many types of appetizers should I serve?

    For fewer than 20 guests, 3-4 types is sufficient. For 20-40 guests, plan 5-6 types. For larger events, 6-8 types provides good variety.
