Here's a handy chart to help determine the right portion sizes for meat joints based on appetite size:
| Appetite Size | Boneless Meat (g per head) | Bone-in Meat (g per head) |
|---|---|---|
| Small Appetite | 125–150 g | 200–250 g |
| Medium Appetite | 150–200 g | 250–300 g |
| Large Appetite | 200–250 g | 300–350 g |
| Extra Large Appetite | 250–300 g | 350–400 g |
These portions are for the main course. If the meat is part of a larger meal with substantial sides, you could reduce the quantities slightly. For feasts or special occasions where people may indulge, consider the higher end of the range.
