How It Works

How Much Ice for an Event

Formula

Total Ice = Guests x Hours x Ice Per Guest Per Hour

Guidelines

  • Indoor/cool weather: 0.25 lb per person per hour
  • Standard: 0.5 lb per person per hour
  • Outdoor/hot weather: 0.75-1 lb per person per hour

    • Always round up and buy extra. Ice is inexpensive and running out is inconvenient.

    Worked Example

    Calculate ice for 25 guests at a 4-hour outdoor summer party.

    guests = 25hours = 4ice_per_guest_lb = 0.5
    1. 01Total ice: 25 x 4 x 0.5 = 50 lbs.
    2. 02In kilograms: 50 x 0.454 = 22.7 kg.
    3. 0310-lb bags: ceil(50 / 10) = 5 bags.
