Food quantity chart for a crowd: 25, 50 and 100 people
One chart for the question every host asks: how much of each thing for 25, 50 or 100 people? The per-person amounts come from university extension quantity-cooking tables, USDA yield data and manufacturers; the totals are straight multiplication, before any extra for seconds. Add about 10%, and round up for big eaters.
The rule of thumb behind the chart
Iowa State University Extension plans 1 to 1½ pounds of food per guest for a party meal. That weight is spread across a main dish (a 3 oz cooked serving is the standard in quantity tables; a main-dish plate is about two), two to four side dishes at 4 to 6 oz each, bread, and dessert. Use the chart to build a shopping list, and the linked calculators to change the per-person amounts for your own crowd.
Main dishes
| Item | Per adult | For 25 | For 50 | For 100 |
|---|---|---|---|---|
| Cooked main dish (one main) | 6 oz cooked | 9.4 lb | 18.8 lb | 37.5 lb |
| Pulled pork sandwiches: raw bone-in shoulder | 4 oz cooked = 0.48 lb raw | 12 lb | 24 lb | 48.1 lb |
| Whole turkey | 1 lb | 25 lb | 50 lb | 100 lb |
| Ham, boneless | ⅓ lb | 8.3 lb | 16.7 lb | 33.3 lb |
| Ham, bone-in | ½ lb | 12.5 lb | 25 lb | 50 lb |
| Ground beef for 4 oz burgers, 1½ each | 6 oz raw | 9.4 lb | 18.8 lb | 37.5 lb |
| Hot dogs, 1½ each (8 per lb) | 1½ | 38 hot dogs | 75 hot dogs | 150 hot dogs |
The raw-weight rows are where crowd cooking usually goes wrong. A bone-in pork shoulder gives only about half its weight as pulled pork, and a whole packer brisket less than half — see how much pulled pork for 50 people and how much brisket for 20 people. Holiday birds are worked through in how big a turkey for 20 people, and ham in how much ham for 50 people and, for a family table, how big of a ham for 10 people. For a seafood boil, how much shrimp per person for a boil gives the per-person figure.
Side dishes
| Item | Per adult | For 25 | For 50 | For 100 |
|---|---|---|---|---|
| Mashed potatoes: raw potatoes | 0.36 lb (4 oz mashed) | 9 lb | 18 lb | 36 lb |
| Mac and cheese or pasta salad: dry pasta | 0.1 lb | 2.5 lb | 5 lb | 10 lb |
| Potato salad | ½ cup, about 4.8 oz | 7.5 lb | 15 lb | 30 lb |
| Coleslaw | about 4.8 oz | 7.5 lb | 15 lb | 30 lb |
| Baked beans | about ¾ cup | 1.3 gal | 2.5 gal | 5 gal |
| Green salad: lettuce | 1 cup salad, 0.19 lb lettuce | 4.8 lb | 9.5 lb | 19 lb |
| Gravy | 3–4 Tbsp (3½ used) | 1.4 qt | 2.7 qt | 5.5 qt |
| Dinner rolls | 1 | 25 rolls | 50 rolls | 100 rolls |
Two or three sides suit a dinner; three or four a buffet or cookout. With more sides, scoops get smaller but the total grows. The worked pages for the most-asked sides are how much mashed potatoes for 100 people, how much mac and cheese for 50 people, how much potato salad for 50 people and how much baked beans for 50 people.
Desserts
| Item | Serves | For 50 |
|---|---|---|
| Half sheet cake, one layer (12 × 18 in) | about 36 party / 49 wedding slices (Wilton) | one or two |
| Half sheet cake (Iowa State’s figure) | 24–50 | one or two |
| Two-layer 10 in round | 28 party / 38 wedding (Wilton) | two |
| Cupcakes | 1–1½ each | 50–75; 3–4 boxes of mix |
| 9 in pies (Clay County) | 8 slices each | 7 pies — see how many pies for 20 people |

Drinks and ice
| Item | Per guest | For 25 | For 50 | For 100 |
|---|---|---|---|---|
| Drinks, 4-hour party (2 first hour, 1 after) | 5 | 125 drinks | 250 drinks | 500 drinks |

| Ice | 1½ lb (Reddy Ice: 1–2 lb) | 37.5 lb | 75 lb | 150 lb |
| Coffee, one 8 oz cup each: urn cups | 1.6 urn cups | 40 urn cups | 80 urn cups | 160 urn cups |
The drink split and cases are in how many cans of soda for 100 guests; punch in how much punch for 50 people; ice in how much ice for 50 people; coffee in how much coffee for a 100 cup urn.
Whole menus at three sizes are worked through in how much food for 20 people at a BBQ, how much food for 50 people and how much food for 100 people. For grazing instead of a meal, see charcuterie board for 50 people.
Adjusting the chart
- Children eat roughly half an adult portion; the calculators count them that way.
- Open houses: Iowa State suggests planning for about 60% of the guests invited, because people come and go.
- Hot weather means more drinks and ice and a little less hot food.
- Big eaters — teenagers, athletes, an all-day event — round up by a quarter.
- Food safety: none of this should sit out more than 2 hours, or 1 hour above 90 °F. See the party food safety guide.
Frequently asked questions
How much food do I need for 100 people?
At Iowa State Extension’s 1 to 1½ lb per guest, about 100 to 150 lb of food: roughly 37½ lb of cooked main dish at 6 oz each, 25 to 30 lb of each side, 100 rolls and 100 desserts, plus about 10% extra.
What is a serving of meat for a crowd?
Quantity-cooking tables use a 3 oz cooked serving. For a main-dish plate at a party, about 6 oz cooked (two servings) is a common plan; for sandwiches, 3 to 4 oz.
