The per-hour rule for party snacks
Guests eat most in the first hour of a party and less after that. Planning by the hour is more accurate than a flat number per head, and it scales naturally for a two-hour kitty party or a four-hour cocktail evening.
Total pieces = Pieces per guest × Guests × (1 + Buffer %)
- Cocktail party: 6 pieces in the first hour and 4 an hour after, because snacks replace dinner.
- Birthday party: 4 then 2 an hour, as cake and a meal usually follow.
- Kitty party or get-together: 5 then 3 an hour.
Example: a three-hour cocktail party for 40 guests needs 6 + 4 × 2 = 14 pieces per guest, or 560 pieces, and about 616 with a 10% buffer. Spread these across four to six snack types, with more of the popular ones such as paneer tikka and chicken kebab.
Drinks, ice and disposables
- Plan 2 drinks per guest in the first hour and 1 an hour after. Glasses here are 250 ml.
- For alcohol, a 750 ml bottle gives about 12 drinks of 60 ml. Add 150 ml of soda or mixer per drink.
- Allow about 250 ml of drinking water per guest per hour.
- Ice: roughly 0.3 kg per guest plus 0.1 kg for each hour, and a quarter more when alcohol is served.
- Plates: 2 per guest, 3 for a birthday with cake; napkins and glasses about 3 per guest.
Running the party smoothly
Serve passed snacks in waves rather than all at once, so the last hour does not run dry. Keep one extra case of water and soft drinks in reserve; unopened stock can usually be used later. Serving liquor needs the right licence and permits, which vary by state, so check before the event.
If the party ends with a full buffet, plan the meal with the banquet menu pricing calculator, and work out drink costs with the bar pour cost calculator. Quantities are planning estimates; crowds differ.
