How Much Food Per Person for a Party: Meat, Sides, Drinks and Ice

When food is the main meal, a common starting point is about half a pound (around 225 g) of boneless meat per adult, or closer to three-quarters of a pound if it is on the bone, plus roughly half a cup of each side dish. Appetizers, pizza, drinks and ice each have their own rough guide, set out below.

These figures are starting points rather than rules. Appetites vary with age, time of day, the length of the party and how much else is on the table, so read the adjustment notes before heading to the shops.

Quantities at a glance

Adjusting for your crowd

• Children. Count younger children as roughly half an adult portion; teenagers as a full one or more.
• Time of day. A mid-afternoon gathering between meals needs less than one that runs through dinner time.
• Length. The longer people stay, the more they graze. Plan a second, lighter round for parties that run late.
• Format. Buffets usually need a little more than plated meals, because guests serve themselves and try everything.
• Variety. More dishes means smaller portions of each, but the total amount of food rises slightly.
• Activity. Outdoor games, swimming and dancing all sharpen appetites.

A worked example

Picture a backyard party for 20 adults and 6 young children, running from early afternoon into the evening, with one grilled main, three sides, a salad, bread and dessert.

1. Count the children as half portions: 20 + 3 = 23 adult portions.
2. Meat: 23 × 1/2 lb comes to about 11.5 lb of boneless meat, or roughly 17 lb if it is mostly bone-in.
3. Sides: 23 × 1/2 cup is about 11.5 cups of each side, so three sides at that size.
4. Salad: around 23 loosely packed cups of greens.
5. Bread: 30 to 45 rolls, leaning high because the party runs through dinner.
6. Dessert: 23 to 35 servings.

Because the party covers a full meal and then some, rounding each figure up slightly is sensible. For a short gathering between meals, the same arithmetic with appetizer counts would be the better fit.

Drinks and ice

A widely used rule of thumb is about two drinks per guest in the first hour and one per guest for each hour after that, counting soft drinks, water and any alcohol together. Always have plenty of water and non-alcoholic choices, and if alcohol is served, make sure guests have a safe way home. For a celebratory toast, the pairing ideas in pairing champagne with everyday food help match bottles to the menu.

For ice, plan on roughly 1 to 2 pounds (about 0.5 to 1 kg) per guest. Lean toward the higher end on hot days, for long parties, or when the same ice also chills drinks in coolers and keeps cold dishes cold on the table.

Avoiding waste without running short

Running out is stressful; a fridge full of leftovers is costly. A few habits balance the two:

• Be generous with inexpensive fillers such as bread, rice, potatoes and salad, and precise with the expensive items.
• Hold back part of each dish and bring it out only when needed.
• Have containers ready so guests can take leftovers home.
• Chill leftovers promptly rather than leaving them out while you tidy up.

When money is the main constraint, the ideas in how to feed a crowd on a budget stretch these quantities further. For serving the food once it is ready, see how to set up a buffet table, and if the party is meant to be a secret, how to plan a surprise party covers the timing.
