Party Food Calculator

The standard is 6 ounces (approximately 170g) of cooked or ready-to-serve protein per person for a buffet. If serving multiple protein options (e.g., chicken and beef), plan 4 ounces of each. Account for cooking shrinkage if purchasing raw — e.g., 8 oz raw beef yields approximately 6 oz cooked.

For a buffet, plan approximately 4 ounces (113g) per person per side dish. If you are serving two side dishes, that totals 8 ounces per person. For a cocktail party, small side offerings like bread, dips, and crudites might total 2 ounces per person.

The 10% buffer built into this calculator typically covers larger appetites. For parties where the guest profile includes many large eaters (e.g., young adults, athletic groups, post-game gatherings), consider increasing the buffer to 15 to 20% or bumping individual quantities up slightly.

As a rule of thumb, plan for 10 to 15% of guests to have dietary restrictions. Ensure at least one vegetarian, one gluten-free, and one dairy-free option. Label all dishes clearly. Having a dedicated vegetarian main increases the options for guests without requiring complete recalculation of protein quantities.

Underestimating the effect of party duration is the most common mistake. Food consumption scales linearly with time — a 4-hour party requires proportionally more food than a 2-hour event. Many hosts plan for time rather than per-hour consumption and are surprised to run out of appetizers midway through a long event.

Children typically consume 50 to 70% of adult portions. If a significant portion of your guest list is children, apply a weighted calculation — count each child as 0.6 adult servings. For kids-specific parties, see the dedicated Kids Party Food Calculator.

For a cocktail party: 4 to 6 different appetizer types for up to 30 guests; 6 to 10 varieties for larger gatherings. For a buffet: 1 to 2 protein mains, 2 to 3 sides, 1 to 2 salads, and bread. Variety improves satisfaction more than quantity per dish.

Hot foods should be kept above 60°C (140°F) and cold foods below 4°C (40°F). Perishable foods should not sit at room temperature for more than 2 hours (1 hour if ambient temperature is above 32°C/90°F). Use chafing dishes for hot items and ice beds or refrigerated trays for cold items.

Preparation timelines vary by dish: dips, spreads, and marinated items can be made 2 to 3 days ahead; cookies and cakes 1 to 2 days; cut vegetables 1 day; hot appetizers and proteins are best prepared on the day of the event. Create a production schedule to avoid last-minute stress.
