A practical starting point
For a mixed BBQ menu, PartyMath uses about 8 ounces of cooked meat per adult-equivalent guest, then works backward to raw weight using realistic cooking yields. For 50 average eaters, a two-meat spread lands around 43.1 pounds of raw meat total.
- About 23.7 lb raw pork shoulder
- About 19.4 lb raw brisket
- About 53 buns or rolls
- About 7 18-oz bottles of BBQ sauce
How much of each side?
If you are serving three classic sides, a useful starting point is around 4 ounces of each side per adult-equivalent guest. For 50 people, that is roughly 12.5 lb of each side before adding a leftovers buffer.
When should you buy extra?
Add 10–20% when the event is long, guests are especially hungry, BBQ is the only food, or you deliberately want leftovers. You can reduce the estimate when there are appetizers, desserts, several proteins, or many substantial sides.
Raw weight matters
Brisket and pork shoulder lose substantial weight from trimming, rendered fat and moisture. Buying only the cooked serving weight will leave you short. That is why PartyMath calculates from expected cooked servings back to raw purchasing weight.

A mixed BBQ spread for 50 average eaters often starts around 43.1 pounds of raw meat total before adjusting for menu variety and leftovers.
Plan purchases by raw weight because smoking and trimming can reduce finished yield substantially.
A 10% buffer is a useful starting point, with more for long events or planned leftovers.
