What changes at 100
The numbers, compared
- A buffet for 100 needs 196.25 lb of food against 148 lb for a plated dinner — people serve themselves and try more dishes.
- Cooked mains: 55.25 lb at a sit-down dinner, 81.75 lb at a buffet with 2 mains, 92.5 lb at a cookout. Buy roughly a third more raw weight for meat.
- Appetizers only: about 890 bites across a 3-hour cocktail party, or 9 a guest.
- On a hot day outdoors the ice rises from 195 lb to 270 lb, because bottles in a tub melt it too.
- Checked against a starting kitchen of 1 oven and 4 burners, the sample menu for 100 is over capacity; the busiest part is serving stations at 714%.

Kitchen check
Over capacity
The day-of cooking does not fit the day. Move dishes to the day before, cut the menu, add an oven, or reduce the guest count. The plan will not compress cooking time for you.
Checked against a starting kitchen of 1 oven and 4 burners — not yours yet. Seats are not counted here: the planner asks for your real number rather than guessing it.

Food for 100: questions hosts ask
How much food do I need for 100 people?
About 148 lb of finished food for a sit-down dinner for 100, or 196.25 lb as a buffet, which is roughly 23.7–31.3 oz a person. These are planning estimates for cooked food, with a small margin for a late guest.
How much meat for 100 people?
Plan about 55.25 lb of cooked main dish for a plated dinner for 100, or 81.75 lb for a buffet that puts out 2 mains. Meat loses about a quarter of its weight as it cooks, so buy around 74 lb raw for the dinner.
How many appetizers for 100 people?
When appetizers are the whole party, about 890 bites for 100 guests over 3 hours. Before a dinner, 462 bites is enough to take the edge off.

About 500 drinks over 4 hours with a mixed bar and most guests drinking: 32 bottles of wine, 126 beers, 5 bottles of spirits, and zero-proof drinks for everyone who isn't drinking alcohol.
How much ice for 100 people?
195 lb of ice indoors with bottles kept in tubs, or 270 lb outdoors on a hot day. That is 10 20 lb bags for an indoor party.
How many rolls for 100 people?
About 109 rolls for a sit-down dinner for 100 — close to one each, since bread is a side people take once.
