Running out of meat is the one hosting failure people remember. Buying twice what you need is the one they don't notice but you pay for. The gap between the two is almost always yield — the weight that disappears between the butcher and the plate.
Start with cooked portions
| Situation | Cooked meat per adult |
|---|---|
| Main event, few sides | 1/2 lb (225 g) |
| Plenty of sides | 1/3 lb (150 g) |
| Big eaters / all-day BBQ | 3/4 lb (340 g) |
| Children under 12 | Half an adult portion |
| Buffet with several meats | 1/4 lb of each |
Our meat per person calculator takes adults, children, serving style and cut type and does the yield maths for you.
Yield is the part that catches everyone
This is where the plan falls apart. Meat loses weight to rendered fat, evaporation, trimming and bone — and how much depends enormously on the cut.
| Cut | Yield | Raw needed per 1/2 lb cooked |
|---|---|---|
| Brisket (packer) | ~50% | ~1 lb |
| Pork shoulder (pulled) | ~50% | ~1 lb |
| Whole chicken | ~50% | ~1 lb |
| Ribs (bone-in) | ~50% | ~1 lb |
| Steak / boneless | ~70–75% | ~0.7 lb |
| Ground beef | ~75% | ~0.65 lb |
Bone-in changes everything
Bone is weight you can't eat, and the ratio varies wildly. Ribs are mostly bone by weight — plan 1 lb of raw ribs per person, or about 3–4 ribs each. A bone-in ham is a different creature to a boneless one at the same weight.
The trade-off is real, though: bone-in cooks more evenly and tastes better. You're buying flavour with the extra weight, not being cheated.
Who's actually coming?
The headcount matters less than the composition. Twenty adults at an all-day BBQ with beer eat very differently from twenty people at a buffet with eight sides.
Children under 12 eat roughly half an adult portion — and often less at a party, because they'd rather be running around. Teenagers eat more than adults, reliably, and are the most commonly under-estimated guests at any party.
The other thing people forget: sides do enormous work. A table with mac and cheese, beans, slaw and bread means people take less meat. Skimp on sides and your meat plan collapses.
Buy about 10% extra — no more
A modest cushion for the unexpected extra guest and the person on their third helping. Beyond that you're buying leftovers you didn't plan for.
Which is fine if you want them — pulled pork and brisket both freeze and reheat well, and plenty of people over-buy on purpose. Just decide that deliberately rather than panicking at the butcher.
Doing dessert too? The cake serving calculator sizes that by the same logic.

Frequently Asked Questions
How much meat per person for a BBQ?
About 1/2 lb of cooked boneless meat per adult, or 1/3 lb if you're serving plenty of sides. Children under 12 eat roughly half an adult portion.
How much brisket per person?
Roughly 1 lb of raw packer brisket per person. Brisket yields only about 50% after trimming and rendering, so half of what you buy is lost in cooking.
How much pulled pork per person?
Around 1 lb of raw pork shoulder per person, which yields about 1/2 lb cooked. Pork shoulder loses roughly half its weight during a long cook.
Do I need more meat if it's bone-in?
Yes. Bone is weight you can't eat, so plan about 1 lb of raw bone-in ribs per person, or 3 to 4 ribs each, compared with less for boneless cuts.
