How Much Ice for a Party? Pounds and Bags Per Guest
Hosting a Christmas party, a holiday open house or a New Year's Eve party on Thursday, Dec 31, 2026? Ice is cheap, but it's the thing hosts run out of first. Here's how many pounds and bags to buy for 4 to 50 guests, how to fill a cooler, and how to keep ice for drinks clean.
The quick answer
- Chilling drinks only (cans and bottles in a cooler or tub): about 1 lb of ice per guest.
- Chilling drinks and serving ice in glasses: about 2 lb of ice per guest.
- Outdoors, in warm weather or by a pool: buy more, about 2 1/2 to 3 1/2 lb per guest.
Reddy Ice, one of the large US packaged-ice makers, gives the 1 lb and 2 lb amounts for a party of about 6 to 8 hours, and notes that outdoor events often need more. The outdoor range comes from the Ace Ice usage chart. For a shorter holiday party, the same amounts give you a little spare, and leftover ice costs very little.
Ice chart by guests
| Guests | Chilling drinks only (1 lb each) | Chilling + ice in glasses (2 lb each) | 10 lb bags (2 lb each) | 7 lb bags (2 lb each) |
|---|---|---|---|---|
| 4 | 4 lb | 8 lb | 1 bag | 2 bags |
| 6 | 6 lb | 12 lb | 2 bags | 2 bags |
| 8 | 8 lb | 16 lb | 2 bags | 3 bags |
| 10 | 10 lb | 20 lb | 2 bags | 3 bags |
| 12 | 12 lb | 24 lb | 3 bags | 4 bags |
| 16 | 16 lb | 32 lb | 4 bags | 5 bags |
| 20 | 20 lb | 40 lb | 4 bags | 6 bags |
| 25 | 25 lb | 50 lb | 5 bags | 8 bags |
| 30 | 30 lb | 60 lb | 6 bags | 9 bags |
| 40 | 40 lb | 80 lb | 8 bags | 12 bags |
| 50 | 50 lb | 100 lb | 10 bags | 15 bags |
Bags are rounded up. Bag sizes vary by store (7, 10 and 20 lb are common), so check the label and divide.
Two kinds of ice: keep them apart
Ice that goes in a glass is food. Ice that has had cans, bottles and hands in it is not clean enough to serve.
- Keep drink ice in its own clean cooler or bucket with a lid and a scoop. Don't let guests scoop with a glass, which can chip and leave glass in the ice.
- Use the rest for chilling ice around cans and bottles.
- If you're only putting cans and bottles on ice, the 1 lb amount is enough. As soon as you serve drinks over ice, plan the 2 lb amount.
How much ice for a cooler?
Reddy Ice suggests a 2:1 ratio of ice to contents, so about two-thirds ice and one-third drinks. As a rough guide from caterers, a cooler or tub packed with cans and bottles takes about 20 lb of ice to fill in around them. For one cooler of drinks, plan at least two 7 lb bags or two 10 lb bags.
To chill drinks faster, add cold water to the ice. Ice water touches the whole can or bottle, so it chills much faster than ice alone. Wine and sparkling wine chill in a bucket of ice and water in about 30 minutes.
Keeping cold food cold
If the party has a buffet, set cold dishes like shrimp, dips and salads in a bowl of ice. USDA advice is to keep cold food at 40°F or colder, and not to leave perishable food out for more than 2 hours (1 hour if it's above 90°F). Plan this ice on top of the drink ice, and keep it apart from drink ice too.
When to buy ice
- Buy it last. Pick up bags within a few hours of the party, or on the way home. Ice left in a hot car or a warm garage melts and fuses into blocks.
- Break up fused bags before opening by dropping the closed bag on the ground a couple of times.
- Don't count on the freezer. A home ice maker or freezer won't hold enough for more than a few guests.
- Keep a spare bag in a closed cooler. A closed cooler in the shade holds ice for hours; an open tub in the sun loses it fast.
Example: New Year's Eve party for 12
Indoors from 9 PM to 12:30 AM, with drinks served over ice and a tub for cans and bottles.
- 12 guests × 2 lb = 24 lb, so buy 3 bags of 10 lb (30 lb).
- One bag goes in a clean, lidded bucket with a scoop for glasses. Two bags go in the drink tub with cold water.
- Put the sparkling wine and sparkling cider in the tub about 30 minutes before midnight.
- Serving a punch bowl instead? See how much punch per person for gallons by guest count and ice-ring tips.
Example: Christmas party for 20
An afternoon open house indoors, with a self-serve drink station and a cold appetizer tray.
- 20 guests × 2 lb = 40 lb for drinks, so 4 bags of 10 lb.
- Add one more bag for the cold appetizer tray, so 5 bags (50 lb) in all.
