About this tool
Ice chills drinks and keeps food cool, and this calculator estimates kilograms from guest count and event length. The guide allows about 0.5 kg per guest for drinks plus a little more for longer events. Buy a little extra in hot weather, and keep ice in a cooler until needed.
Frequently asked questions
Does hot weather change the amount?
Yes. Heat melts ice faster, so buy extra and keep coolers shaded and closed as much as possible.
Can I make ice at home instead?
Yes, but start days ahead. Home freezers make small batches, so a party usually still needs bought bags.
