How Many Pounds of Ribs per Person? Spare Rib Yield
A pound of pork spareribs gives about 0.39 lb of cooked lean meat in the USDA Food Buying Guide, so plan about 1 lb of raw ribs per person for 6 oz of meat. Most of the rest is bone, 30% of raw spareribs in USDA’s nutrient database, plus fat and cooking loss: roasted spareribs kept 76% of their weight in USDA cooking tests.
