How many drinks per person per hour is typical?

A common rule is 1–2 drinks per person per hour. A relaxed dinner party runs about 1, a casual gathering 1.5, and a lively event 2. The calculator defaults to 1.5.

How much ice do I need?

A general rule is 1–1.5 lb of ice per guest for chilling drinks. Add roughly 50% more if you also need to fill coolers. The calculator estimates 1.25 lb per guest-hour as a balanced default.

Does this account for non-drinkers?

Yes. Set the soft-drink percentage to cover non-drinkers and designated drivers. Any guest percentage not assigned to alcohol categories is treated as non-alcoholic.

How many drinks are in a bottle of wine?

A standard 750 ml wine bottle yields roughly 5 glasses (5 oz each). The calculator uses this when converting wine drink counts to bottles.

How many beers come in a case?

A standard case holds 24 cans or bottles. The calculator rounds up to full cases so you never come up short.
