How Much Food Per Person for a Party? A Catering-Style Chart
September 12, 2026
Twelve people are coming on Saturday. You have a chilli recipe that “serves six,” so you double it, buy what feels like a reasonable amount of everything else, and hope. One of two things then happens. Either the pot is scraped clean forty minutes in and you are quietly making toast for the people who arrived late — or you are eating chilli for lunch every day until Thursday.
Both failures come from the same mistake: you planned by recipe, and a recipe has no idea how many people are in your kitchen. “Serves six” is one cook’s guess about one dish, eaten by nobody in particular, on a day with no other food on the table.
Caterers never work this way. A caterer costing a wedding does not think in recipes at all. They think in grams per guest — so many grams of protein, so many of starch, so many of salad — multiply by the headcount, and only then work backwards to what to actually cook. That single switch is the whole trick, and it is why professionals almost never run out.
The short answer
Per adult, for a normal dinner where the main dish is the event:
- Main protein: 220 g raw (about 7.8 oz), which cooks down to roughly 165 g / 5.8 oz
- Sides: 175 g total, spread across about two of them
- Salad or vegetables: 90 g
- Bread: 1–2 rolls
- Dessert: 110 g
- Drinks: 2–3 servings for a two-hour meal, more for a long party
- Ice: 250 g in the glasses — far more if you are chilling bottles
A child counts as roughly 60% of an adult. Those are the figures behind our party food calculator, which takes your adult and child counts plus the kind of meal and does the multiplication in US or metric units.
The per-person chart
This is the whole plan on one screen. Everything is per adult; the protein row is raw purchase weight, because that is the number you need at the shop.
| Item | Per adult (metric) | Per adult (US) | Notes |
|---|---|---|---|
| Main protein (raw) | 220 g | 7.8 oz | dinner portion — see the meal-type table below |
| Side dishes (total) | 175 g | 6.2 oz | across about two sides |
| Salad / vegetables | 90 g | 3.2 oz | as an accompaniment, not a main |
| Bread / rolls | 1.5 pieces | 1.5 pieces | round up; see the note below |
| Dessert | 110 g | 3.9 oz | one generous slice |
| Drinks | 2.5 servings | 2.5 servings | 3 if it is a drinks-and-nibbles party |
| Ice | 250 g | 0.55 lb | for the drinks themselves |
Multiplied out for common guest counts — 4 to 50 — this is the printable party food quantity chart, which is the version to take to the shop.
Add up the solid food and you get just under 600 g — about 1.3 lb of food per adult, which is the number caterers quote as a sanity check when they say “plan a pound and a quarter per head.” If your menu totals wildly more or less than that per guest, something in the plan is off.
One line in that table is a genuine judgement call rather than a settled number, and it is worth saying so: bread. We use 1.5 pieces per adult; WebstaurantStore says 1 to 2; Ellen’s Kitchen’s crowd chart is markedly more generous at four dozen rolls per 25 guests, which is 1.9 each. The spread is real, and it comes down to whether bread is a side or a vehicle. If people are building sandwiches or mopping up a stew, use two a head and buy the extra loaf — bread is the cheapest insurance on the table.
Protein changes with the kind of meal; the rest barely moves
The single biggest variable is what role the protein plays. A cookout where people eat three sausages standing up is not a lunch where the chicken shares the plate with a grain salad.
| Meal type | Main protein per adult (raw) | Cooked equivalent |
|---|---|---|
| Appetizers only | 90 g / 3.2 oz | ~2.4 oz |
| Lunch | 170 g / 6.0 oz | ~4.5 oz |
| Dinner (plated) | 220 g / 7.8 oz | ~5.8 oz |
| Buffet | 270 g / 9.5 oz | ~7.1 oz |
| BBQ / cookout | 280 g / 9.9 oz | ~7.4 oz |
Sides, salad, bread and dessert stay put across all of these. That is not laziness in the model — it reflects how people actually eat. Appetite for potato salad does not swing much between a lunch and a barbecue; appetite for the meat does.
Run those cooked numbers against the trade guidance and they land where they should. WebstaurantStore’s catering portion guide puts a plated main at 4 to 6 ounces of protein per person and a buffet or barbecue at 6 to 8. Our dinner setting cooks down to 5.8 oz — top of the plated band. Buffet lands at 7.1 oz and BBQ at 7.4 oz — both mid-band for self-service. The chart is the same advice, expressed in the weight you can actually buy.
Why the protein number is a raw weight
Because meat shrinks, and the loss is not small. Cooking drives off moisture and renders fat, and the USDA maintains an entire reference for it — the Table of Cooking Yields for Meat and Poultry, which defines cooking yield as simply the cooked weight divided by the raw weight, and publishes a separate figure for every cut and cooking method because they genuinely differ.
For party planning, assume you keep about three-quarters of what you buy. That is the assumption baked into the 220 g figure above: buy 220 g raw, serve roughly 165 g. It is also why a “serves eight” roast recipe and a caterer’s spreadsheet can disagree by a kilogram — one of them counted the water.
Two corollaries worth knowing at the counter:
- Bone-in costs you again. Bone is weight you pay for and nobody eats. Add roughly a third on top for bone-in cuts and whole birds. Ellen’s Kitchen, whose crowd-cooking charts have been a reference for decades, lists 13 pounds of bone-in chicken for 25 servings — about half a pound per person, which is the same meal as our 220 g once you take the bones out.
- Fatty cuts shrink harder than lean ones. A pork shoulder or a chuck roast loses more than a lean rump, so err upward on anything you plan to shred.
Buffet versus plated: the disagreement worth understanding
Ask the trade whether a buffet needs more food than a plated dinner and you will get two confident, opposite answers.
Most caterers say a buffet needs more — substantially more. Hugh’s Catering states plainly that buffet service requires 20 to 25% more food than plated, and that professionals build a 5 to 10% buffer into every calculation on top of that. The logic is simple: on a plated meal you decide the portion. On a buffet the guest does, and the guest is holding the spoon while looking at a full tray. First in line always takes more than the last in line gets.
A minority say the opposite. Flex Catering’s portion guide argues that a formal plated dinner requires more food per guest than a buffet, and it is not a typo. Their reasoning is about courses: a plated dinner is a fixed, guaranteed sequence — everyone gets the starter, everyone gets the main, everyone gets the dessert — whereas a spread lets a guest take three things and skip the other five.
The weight of the evidence is not close, though, and it points one way. WebstaurantStore files buffets in the same 6-to-8-ounce band as barbecues, explicitly above the 4-to-6 it gives plated service. Hugh’s puts the gap at 20 to 25%. Two independent sources, one conclusion: self-service costs you about a fifth more protein than plating it yourself. Flex Catering’s argument holds only for a formal multi-course dinner where every guest is guaranteed a starter, a main and a dessert whether they want them or not — a service style most home hosts are not running.
So the Buffet setting puts the main protein at 270 g per adult: dinner’s 220 g plus 23%, landing at 7.1 oz cooked, mid-band on both sources. It sits just below BBQ, which is where you would expect it.
The rule that actually keeps you out of trouble: whoever holds the spoon sets the portion. Every step you take away from a plated plate — a serving tray, a carving station, a table people walk back to — moves that decision from you to your guests, and guests are generous with themselves. Plan the extra fifth and you will not be the host watching the last four people arrive at an empty tray.
Ice: the thing everybody gets wrong
The 250 g per person in the chart is ice in the glasses — the cubes that end up in drinks over a couple of hours indoors. That is exactly what the calculator’s ice row is scoped to, and it says so. If that is genuinely all you need, it is enough.
It very often is not, and this is where home hosts miss by a factor of three or four. Reddy Ice, which sells ice for events, works to one to two pounds of ice per person attending — roughly 450 to 900 g each, against our 250 g. The gap is not a contradiction. It is chilling versus serving. Ice sitting in a cooler keeping forty bottles cold is doing a completely different job from the two cubes in a glass, and it is the cooler that eats the bags.
Tasting Table’s breakdown for a 20-guest, four-hour event makes the arithmetic uncomfortably concrete: about 19 pounds to serve drinks, 40 pounds to chill the beverages, doubled to 80 in hot weather, plus about another pound per guest if you are icing food. That is roughly 100 pounds of ice for twenty people.
So plan ice in three separate lines, not one:
- In the drinks — the 250 g per guest the calculator gives you.
- In the coolers — 1 to 2 lb (450–900 g) per guest, and closer to 2 lb if anything is outdoors or the day is warm. Ice melting in a cooler is not wasted; it is the cooler working.
- Under the food — another pound per guest if you are keeping anything on ice.
And buy it late. Ice bought the morning of a party has already spent hours melting in your freezer by the time the first guest arrives.
Drinks, and what a long party does to every number
The 2.5 servings per adult in the chart assumes a meal — people sit, eat, drink with the food, and go home. A party is a different shape. The standard event-planning rule, which Gotham Catering states as two drinks in the first hour, then one per hour after, is the one to use once your event has a duration rather than a sitting: a four-hour party is five drinks a head, double the meal figure. They also suggest counting non-alcoholic drinks separately at one per guest per hour, which is the line most hosts forget entirely.
Food behaves differently from drink over a long event, and it is worth being precise about how:
- Protein does not scale with hours. Nobody eats a second dinner because the party ran late. Keep the per-head protein figure.
- Nibbles absolutely do. Snacks, bread, crisps — anything within arm’s reach of a conversation gets eaten continuously. WebstaurantStore’s guide counts passed appetizers at 4 to 6 pieces per person per hour: a rate, not a total. For a drinks party, the hours are the multiplier.
- Dessert stays flat, but put it out late; it disappears the moment it appears.
- Ice is a rate. Melt is a function of time and temperature, not headcount. See above.
That is the real difference between the Dinner and Appetizers only settings on the party food calculator — appetizers drop the protein to 90 g per head and push the drinks up, because you are feeding a duration rather than a plate.
The adjustments the chart does not make for you
Children. The calculator counts a child as 0.6 of an adult, which is a deliberately mid-range assumption. A four-year-old eats a third of an adult portion; a fifteen-year-old often eats more than one. If your guest list is mostly teenagers, enter them as adults and do not overthink it. The trade guides are notably quiet on a specific number here — Hugh’s notes that demographics move portion sizes without ever quantifying it — so 60% is a working figure, not a standard.
Who is actually coming. The calculator’s own advice is to trim 10–15% for a lighter crowd and add for big eaters, and that judgement is yours. A book club and a rugby team with the same headcount are not the same shopping list.
Time of day. Early evening eats less than a proper dinner hour. A late-night event where people have already eaten elsewhere eats far less than either.
The number of options. Counter-intuitively, more choices means more total food, not less — people take a bit of everything. If you are cooking six dishes rather than three, do not cut each one in half.
The buffer. Professionals build in 5 to 10%; the calculator’s advice is to cook one or two extra portions outright. Running out is a memorable failure; a bit of leftover roast is not.
Worked example: fifty guests
Since “how much food for 50 guests” is the question people actually type, here is the whole plan at 50 adults, dinner portions, straight from the chart:
| Item | Total for 50 adults |
|---|---|
| Main protein (raw) | 11 kg / 24.3 lb |
| Side dishes | 8.75 kg / 19.3 lb |
| Salad / vegetables | 4.5 kg / 9.9 lb |
| Bread / rolls | 75 pieces |
| Dessert | 5.5 kg / 12.1 lb |
| Drinks | 125 servings |
| Ice (in the drinks) | 12.5 kg / 27.6 lb |
Sanity-check the protein against Ellen’s chart: 13 lb of bone-in chicken per 25 servings scales to 26 lb for fifty, against our 24.3 lb of boneless raw weight. Two independent sources, within a couple of pounds. That is what a stable number looks like.
And note the ice line. Those 27.6 lb are what goes in the glasses. If those fifty people are in a garden in July with the drinks in coolers, you are buying 50 to 100 lb on top of it. Nobody has ever regretted a spare bag.
Cooking it, and keeping it safe
Two things worth saying plainly, because a crowd changes the risk profile of a kitchen:
- Cook to internal temperature, never to the clock. A larger roast, a colder fridge or a crowded oven all move the timing, and the only honest way to know a big piece of meat is done is a thermometer in the thickest part.
- Hot food hot, cold food cold, and do not leave a buffet standing indefinitely. For the actual rules on holding times and temperatures, follow current food-safety guidance from your national food-safety authority rather than a chart on a blog — including ours.
Putting it together
Stop asking whether a recipe serves enough people. Start with the headcount, multiply by the per-guest figures, and let the menu fall out of the total. That is what caterers do, and it is the reason they are not making emergency toast at nine o’clock.
Put your numbers into the party food calculator and it will hand you the whole shopping list — protein, sides, salad, bread, dessert, drinks and ice — for your exact mix of adults and children, in US or metric units.
From there the rest is execution. If you are pouring for a crowd, the cocktail batch calculator turns a single-serve recipe into a pitcher or a dispenser without the on-the-spot arithmetic. Once you know the target weight of each dish, the recipe scaler multiplies your actual recipes up to match and gives you a copyable ingredient list. And if the centrepiece is a bird, the turkey cooking time calculator works backwards from the time you want to serve, so the oven schedule fits around everything else — and it is worth seasoning it properly first, which is the argument we make in how much salt goes in a brine.
