How to Estimate Portions for Your Guest Count

Why Portion Planning Matters

One of the biggest challenges in event planning is making sure everyone eats well without overbuying. Ordering too little food leaves guests hungry, while ordering too much leads to unnecessary cost and waste. With the right formulas, you can plan confidently—whether for a wedding, corporate gathering, or private dinner.

General Portion Guidelines

These estimates are a good starting point for most events:

ItemPer Person EstimateAppetizers6–8 pieces (lighter events) or 10–12 pieces (heavier mingling)Main Course Proteins4–6 oz cooked meat, poultry, or fishSide Dishes4–6 oz per sideSalads1 cup per personBread/Rolls1–2 piecesDessert1 slice of cake or 3–4 mini dessertsDrinks2–3 beverages in the first hour, 1 per hour after

Adjust for Event Style

1. Cocktail or Networking Night

With no formal meal, people tend to eat more appetizers—plan for 10–12 bite-sized pieces per person and include a mix of savory and sweet.

2. Buffet or Family-Style Dinner

Expect guests to try a bit of everything. Plan 1.5 servings per person for popular sides to avoid running out.

3. Plated Dinner

With a set menu, portions are easier to control. Stick close to the 4–6 oz protein and 4 oz sides rule.

4. Kids vs. Adults

Children generally eat half the adult portion, though this varies with age and activity level.

Special Considerations

  • Time of Day: Guests eat more at dinner than at a mid-afternoon reception.

  • Length of Event: For events longer than 3 hours, add a snack or late-night station.

  • Alcohol Service: People tend to eat a bit more when drinks are served.

  • Dietary Needs: Offer vegetarian or allergen-friendly options and calculate them into your total.
