How much food should I serve per person at a party?
As a general rule, plan for about 1 lb (450g) of food per adult for a full meal — split across protein, sides, and salads. For a cocktail or appetizer-only party, budget 6–8 bite-sized pieces per person per hour. Children aged 3–10 typically eat about half an adult portion, and toddlers even less.

How many appetizers per person should I prepare?
If appetizers are served before a full meal, plan for 4–6 pieces per guest. If it's a cocktail party with no main meal, budget 8–12 pieces per person per hour. Having a variety of 3–5 different appetizers keeps the spread interesting and accommodates different tastes.
Do guests eat more at dinner parties than at casual gatherings?
Yes — sit-down dinner parties typically see higher consumption because guests are seated and served in courses, encouraging them to eat more. Buffet and cocktail-style parties often result in slightly less food consumed per person since guests self-serve and tend to graze. This calculator adjusts quantities based on your selected party type and meal style.
How much food do I need for a 3-hour party?
For a standard 3-hour dinner or buffet party, plan for a full meal's worth of food: roughly 0.5 lb of protein, 0.75 lb of sides combined, plus dessert per adult. For a 3-hour cocktail party, aim for 8–10 appetizer pieces per person. The longer the event, the more guests will eat — especially if alcohol is being served. You might also find our Taco Bar Calculator useful.
How do I adjust food quantities for children?
Children aged 3–10 generally eat about half the portion of an adult, while teenagers eat roughly the same as adults. Toddlers (1–2 years) need only a quarter of an adult portion and usually eat separately. This calculator uses adult-equivalent portions to account for your specific guest mix automatically.
How much meat should I serve per person at a party?
For a main course, plan on 6–8 oz (170–225g) of boneless cooked meat or protein per adult. For bone-in cuts like chicken pieces or ribs, increase this to 0.75–1 lb per person since bones add weight. If meat is one of several proteins (e.g. a mixed BBQ), you can reduce individual quantities slightly.
What about guests with dietary restrictions?
A good rule of thumb is to ensure at least 20–30% of your food options are vegetarian or vegan-friendly, regardless of whether you know specific guests have restrictions. Always label dishes clearly and have at least one allergen-conscious option (gluten-free, nut-free) available. Ask guests in advance when possible.
Can I use this calculator for buffet-style parties?
Absolutely. For buffets, guests tend to take smaller initial portions but return for seconds, so total consumption often equals a standard sit-down meal. The key advantage of buffets is variety — offering 6–8 different dishes means guests spread their eating across options, reducing how much of any single dish you need. This calculator factors in meal style when estimating quantities. Check out our How Much Mashed Potatoes per Person as well.
