How to calculate home party food amounts
Too little food is embarrassing; too much creates waste. For a full sit-down meal, plan about 14β18 oz (400β500g) of food per guest. Snack parties need 9β11 oz (250β300g), and buffet-style spreads need 18β22 oz (500β600g). Longer parties naturally need more food, and alcohol tends to reduce food consumption by 10β20%.
For drinks, figure 2β3 non-alcoholic beverages (about 16 oz each) per person for a 3-hour party. If you're serving alcohol, add 2β3 beers or a third of a bottle of wine per adult. A 10β15% buffer handles last-minute guests without creating significant waste.
