Meat Per Person Calculator

About this calculator

This calculator multiplies your guest count by a per-person serving size (commonly cited as 150–225 g (½ lb) of boneless meat per adult for a main course, more for bone-in cuts like ribs or whole chicken) to get the total raw weight to buy, shown in both grams and kilograms.

Hosts planning a barbecue, holiday dinner or catered event use this to avoid the two common failure modes: buying too little and running short, or buying too much and wasting money on leftovers that spoil. The right per-person figure varies with the cut (bone-in needs roughly 30–50% more), the number of side dishes, and whether the meat is the meal's centerpiece or one of several proteins.
