Party Food Calculator

Figure out exactly how much food to buy for your party or event so you have enough for everyone without wasting money on leftovers.

adults

Casual serves slightly smaller portions. Generous adds about 20% more food across the board.

How to use this calculator

Start by entering the number of adults and kids attending your event. Kids are counted as half portions since children under 12 typically eat about half of what adults eat.

Next, select the meal type. A full meal includes protein, sides, salad, bread, dessert, and drinks. An appetizers only event calculates finger food quantities based on how many hours your event will last. You can also choose light bites for a casual gathering that falls somewhere in between.

The calculator gives you per person amounts and total quantities for every food category. Use the totals as your shopping list. If you are serving multiple protein options (like burgers and chicken), divide the total protein amount between them rather than buying the full amount of each.

The drink and ice estimates account for event duration. Guests drink more in the first hour and taper off, so longer events do not simply multiply the per hour rate. The ice estimate includes both drinks and cooler needs.

General food quantity guidelines

For a full meal, plan on about 1 to 1.5 pounds of total food per adult guest. That breaks down to roughly 6 to 8 ounces of protein (raw weight), 4 to 6 ounces each of two or three side dishes, 2 to 3 ounces of salad, and 1 to 2 rolls or pieces of bread.

Keep in mind that raw meat loses weight during cooking. Burgers and chicken lose about 25 percent, while slow cooked meats like pulled pork and brisket can lose 40 to 50 percent. The calculator accounts for this by estimating raw purchase amounts, not cooked serving sizes.

For appetizer only events, the standard is 6 to 8 pieces per person per hour. Offer at least 3 to 4 different options so guests have variety, and plan for heavier items if the event falls during typical meal hours.

Frequently Asked Questions

How much food do I need per person for a party?

A good rule of thumb is about 1 to 1.5 pounds of total food per adult guest for a full meal. This breaks down to roughly 6 to 8 ounces of protein, 8 to 12 ounces of sides (across two or three dishes), 2 to 3 ounces of salad, and 1 to 2 rolls. For appetizer only events, plan for 6 to 8 pieces per person per hour.

How do I adjust food quantities when kids are attending?

Children generally eat about half of what adults eat. For kids under 12, plan for roughly 3 to 4 ounces of protein and half portions of sides. You can also swap in kid friendly options like chicken tenders or mac and cheese, which tend to be more popular with younger guests.

How many drinks should I plan per person at a party?

Plan for about 2 to 3 drinks per person during the first hour, then 1 additional drink per person for each hour after that. For a 4 hour party with 20 guests, that means roughly 100 drinks total. Stock a variety of options including water, soda, and juice.

How much ice do I need for a party?

The standard recommendation is about 1 pound of ice per guest. If you are serving drinks that need to stay cold in coolers or ice buckets, add an extra half pound per person. For hot weather outdoor events, double the total amount to account for faster melting.
