How much food for a party?
Tell it how many people, what kind of event and how long it runs. You get a shopping list you can take to the shop, not a vague rule of thumb.
How this is calculated
Every quantity below comes from published catering guidance, applied to your guest count. Nothing here is a guess dressed up as a number.
Per-person figures used
| Item | Per adult | Note |
|---|---|---|
| Total food | 1–1.25 lb | Caterer's working figure across everything |
| Protein | 6–8 oz | 8 oz for barbecue — bone and shrinkage |
| Each side dish | 4–6 oz | Two sides assumed |
| Salad | 1 cup | About 2 oz of leaves |
| Appetisers | 4–6 pieces | 8–10 if no meal follows |
| Dessert | 1 serving | 1.5 if it is the main event |
| Drinks | hours + 1 | Two in the first hour, one per hour after |
| Ice | 1.5 lb | 2 lb outdoors or chilling bottles in tubs |
| Buffet allowance | +12% | Self-service means bigger helpings and seconds |
The two assumptions to check
Children count as half an adult. That is a working figure, not a published standard. A table of teenagers eats like adults; toddlers barely register.
Everything rounds up. Leftovers are an inconvenience, running out is what guests remember. The exception is anything that spoils quickly and cannot be frozen — dressed salad, cut fruit — where buying to the number is the better call.
What the numbers will not tell you
Timing changes appetite more than any chart: a party that starts at 7pm feeds hungry people, one that starts at 3pm does not. Dietary requirements are not a percentage of the total either — one vegan guest needs a whole dish, not a slice of one. And a single spectacular centrepiece dish will always be eaten faster than the model expects.
Questions people actually ask
How much food per person for a party?
The working figure caterers use is about 1 to 1.25 pounds of food per adult across everything on the table. That total splits roughly into 6–8 oz of protein and 8–12 oz of sides, salad and bread. The number moves with the format: a standing cocktail party needs no main at all, while a buffet needs 10–15% more than a plated dinner because people serve themselves generously and come back.
Why does a buffet need more food than a plated dinner?
Because portion control moves from the kitchen to the guest. People take more than a plated serving, they take seconds, and the last servings of a tray never get scraped out. The standard allowance is 10–15% on top, and this calculator adds it automatically when you choose buffet.
How many drinks should I buy?
The long-standing rule is two drinks in the first hour and one per hour after that, which works out as guests × (hours + 1). It is deliberately slightly generous — the spare drink covers the fast first hour, spills and the guest who stays late. Running out an hour before the end is the single most common hosting mistake.
How much ice do I actually need?
One to one and a half pounds per guest for a normal indoor event, and closer to two pounds if it is outdoors in summer or you are chilling bottles in tubs rather than just filling glasses. Ice is the thing hosts under-buy most often, partly because it is easy to forget it is also doing the cooling, not just going in the glass.
How do children count?
This tool counts a child as roughly half an adult portion for food and gives them soft drinks only. That is a working assumption rather than a published standard — a hungry twelve-year-old eats like an adult and a toddler eats almost nothing, so adjust if your guest list skews one way.
Should I round up or down?
Up, always, and the calculator already does. Leftovers at a party are an inconvenience; running out is the thing people remember. The one exception is anything that spoils fast and cannot be frozen — dressed salad, cut fruit — where buying to the number is sensible.
