Ask for 14 at about 14.5 lb each. Stagger the start times so they don't all hit the stall together.
Assumes 200 adults, brisket plated as the main dish, a couple of sides, no leftovers.
Two hundred people plated is 100 pounds of cooked brisket from 200 pounds raw — fourteen whole packers — and the only honest first question is whether you should be cooking it at all. A competent barbecue caterer will charge less than your equipment rental, meat bill, and lost weekend combined, and they carry the food-safety liability that comes with feeding two hundred people. If it's a community effort with volunteer pitmasters and borrowed rigs, run it like the operation it is: sandwiches only (67 pounds cooked), two smokers minimum, briskets staggered in waves, a written hold schedule, and someone whose only job is temperatures. The calculator above still does the per-person math if the crowd shifts — the logistics are on you.
The math, worked out
Every number on this page comes from the same two steps. Here it is longhand for 200 adults eating brisket as the main dish:
2. Raw weight to buy (about 50% is lost to trimming and cooking) 100 lbs × 2 = 200 lbs raw
Want leftovers? Add 15 percent and buy 230 lbs instead — that's about 50 extra meals once the party's over.
200 people, by how you're serving
Serving style moves this number more than anything except sides. Here's all three, with and without a full spread of side dishes:

All weights are raw, untrimmed pounds — what you hand to the butcher. "Full spread" means three or more substantial sides.
If some of your 200 are kids
Kids eat about a quarter pound of cooked brisket each, half what a plated adult puts away, and they fill up on sides and rolls faster than you expect. Swapping four adults for four kids in a group of 200 takes roughly 2 lbs off your raw weight. Worth doing properly rather than guessing —put your real split into the calculator.
Cooking for 200: the logistics
At this scale the smoker stops being the bottleneck — the serving line is. Sliced brisket dries in fifteen minutes, so slice in waves, one brisket at a time, with one person on the knife while the rest wait wrapped in coolers. A written hold schedule — which brisket comes out, at what time, in what order — is worth more than any thermometer.
Ordering 14 packers is not a grocery run: call your butcher two to three weeks ahead and ask for cuts from the same lot. Number every brisket, log when it went on and came off, and give someone the single job of watching temperatures.
