Frequently asked questions
Common answers about party food planning, portion sizes, and how to make sure you have enough for every guest.
How many appetizers per person for a party?
For a cocktail party where appetizers are the only food, plan 6 to 8 pieces per person. If appetizers are served before a full meal, 3 to 4 pieces per person is enough to keep guests satisfied without filling them up before the main course.
How much meat per person for a party?
Plan for 6 to 8 ounces (roughly half a pound) of cooked meat per adult guest. For a buffet with multiple protein options, you can reduce this slightly since guests tend to take smaller portions of each. Adjust upward for heavy eaters or outdoor events where appetites run larger.
How many drinks per person for a party?
A reliable rule of thumb is 2 drinks per person for the first hour and 1 drink for each additional hour. For a 4-hour party with 20 guests, that means about 100 drinks total. Mix alcoholic and non-alcoholic options and always have plenty of water available.
How do I calculate food for a buffet vs. a sit-down dinner?
Buffets typically need 15 to 20 percent more food than plated dinners because guests serve themselves and portions are harder to control. This calculator automatically adjusts quantities based on the meal type you select, so the buffet option includes that extra buffer.
What is the best way to avoid running out of food at a party?
Use the heavy eaters setting if you are unsure, add an extra 10 percent buffer for outdoor events or long parties, and round up when buying. It is better to have leftovers than to run short. Focus extra quantities on the most popular items like mains and beverages rather than distributing extra evenly across every category.
