How to use it
Use this as a planning estimate, then adjust for the actual crowd. A short board-game night, a children's party and a long sports watch party will not eat at the same pace.

Formula
Snack servings = guests x hours x snack servings per person per hour. Drink refills use the same structure, then assume about 250 ml per refill.
Example
For 12 guests over 3 hours at 1.5 snack servings each per hour, the estimate is 54 snack servings. That might mean several bowls, trays or packets depending on what you serve.
Common mistake
Do not treat the number as exact. Round up when the party runs through a meal time, includes children or has long gaps between planned food.
