These are planning estimates. Adjust for your guests, menu, package sizes and weather. Alcohol quantities are stock estimates only—never a safe-consumption recommendation.
Plan by menu role, not one mystery weight.
A tray of appetizers and a full dinner solve different jobs. This calculator keeps those categories separate, converts children to smaller portions and lets appetite change the total.
- 1Count adults and children.
- 2Choose snacks, a full meal or a pizza-style party.
- 3Pick light, average or hungry appetites.
- 4Use the three estimate levels and change quantities for your actual recipes.
Example: a full meal for 30 guests
Twenty-four adults and six children count as 27.9 adult-equivalent portions in the food model. The result separately lists appetizers, mains, cups of sides and desserts so you can map them to your menu.
Party Food Calculator FAQ
How much food do I need for a party?
Count adults and children, choose snacks or a full meal, and select a light, average or hungry crowd. The calculator returns appetizer pieces, main servings, side-dish cups and desserts.
How are children counted?
For food planning, each child counts as 0.65 of an adult portion. Ages and appetites vary, so adjust upward for teens or especially hungry children.
Should I use the minimum or extra result?
Minimum can suit a light crowd with several menu choices. Extra gives more room for seconds, surprise guests or a party where food is the main activity.
How long can party food sit out?
Perishable food should generally not stay at room temperature for more than two hours, or one hour above 90°F. Keep hot food hot and cold food cold.
