Overview

The Serving Size Calculator determines the right amount of food for events, gatherings, and parties based on the number of guests. It provides per-person portion guidelines for different meal types — sit-down dinners, buffets, barbecues, and snack tables — and calculates total quantities needed with optional cost estimates.

Formula

Total food = Per-person portion x Number of guests x Buffer factor (usually 1.1-1.2). Typical per-person servings: rice/grains 200g, meat (grilled) 200-250g, salad 80-100g, beverages 300-500ml. Buffet total per person: approximately 500-700g.

Tips

  • For events with children, calculate at 50-70% of adult portions.
  • Always add a 10-20% buffer to avoid running short.
  • For barbecue, calculate raw meat weight — it shrinks about 30% during cooking.
  • If appetizers are served before the main meal, reduce main course portions by 10-15%.

FAQ

Q. How much food should I prepare per person for a buffet?

For a buffet, plan 500-700g of total food per person: 200-250g for the main course, 150-200g for side dishes, and 100-150g for salads and desserts. For longer events, increase by about 20%.

Q. How do I calculate meat for a barbecue?

Plan for 250-350g of raw meat per adult. Bone-in cuts (ribs, bone-in steaks) require 400-500g per person since the bone weight doesn't contribute to edible portions. Having substantial side dishes can reduce the amount of meat needed.

Q. Should I factor in no-shows?

For casual events, expect about 10-20% of guests to not show up. For formal events (weddings, corporate dinners), no-show rates are typically 5-10%. Plan based on confirmed RSVPs plus your buffer percentage.
