Party food: how much should I buy?
For a full meal, plan about 1 to 1.5 pounds of total food per adult. Children usually need about half to two-thirds of an adult portion. For buffet-style parties, reduce each individual dish because guests take small portions of several foods. Drinks usually scale by event duration, not just headcount. Use this party food calculator below to turn guest count into grocery quantities, package counts, and estimated cost. If you are calculating food for a party for the first time, this food calculator for party planning gives you a complete shopping list in seconds, no weird decimals.

Party food per person: common questions
How do I calculate how much food to buy per person for a party?
Enter your guest count, party type and meal style into a party food calculator. It converts servings into grocery units like pounds, bags, cans and bottles so you know exactly what to buy.
What is the standard serving size per person for a buffet?
For a buffet, plan about 0.75 to 1 pound of total food per adult because guests take smaller portions of multiple dishes. Each side dish runs about 0.15 to 0.25 lb per person when several sides are available.
How much food should I buy for a backyard BBQ?
For a backyard BBQ, plan about 1 to 1.25 pounds of food per adult, split across meats, sides and dessert. Add drinks at 1.5 to 2 per person per hour for outdoor events.
How is food planning different for a large group vs a small party?
Small parties (under 15) let you guess portions easily. Large groups (50+) need organized categories: multiple mains, 4 to 6 sides, and bulk supplies. A calculator prevents overbuying at scale.
What factors should I consider when estimating party food?
Consider guest count, event duration, meal style (full meal vs snacks), time of day, weather for outdoor events, and whether alcohol is served. Each factor changes how much people eat and drink.
When should I use a potluck calculator instead?
Use a potluck calculator when each guest brings one dish rather than one person buying everything. A potluck planner divides the menu into categories so the group covers mains, sides, desserts, drinks and supplies.
