How big a cooler do 7 people need for 3 days?

Food for 7 people over 3 days takes about 26 quarts at 1.25 quarts per person per day. At three canned drinks each per day, drinks add 28 quarts (63 cans). Then ice goes in at 1.5:1 to the contents, because a weekend needs the ice to outlast two or three warm days. That totals about 137 quarts.

For this trip length, a 5-day or marine-rated cooler is worth it.

How do you keep ice for 3 days?

Pre-chill the cooler the night before with a sacrificial bag of ice, pack cold food straight from the fridge, fill air gaps with more ice, and keep it in shade. In a 5-day rated cooler at an 85F high in shade, the ice calculator estimates about 3.6 days of ice for a 150 quart cooler. That covers the trip with some margin.

Frequently asked questions

How much ice for 7 people over 3 days?

At the 1.5:1 ice to contents ratio that suits 3 days, plan about 98 lb of cubed ice across your coolers, roughly 10 ten-pound bags. Block ice or frozen water jugs on the bottom last longer than cubes. On a hot trip, a mid-trip top-up is cheaper than buying a much bigger cooler.

Should 7 people use one cooler or two for 3 days?

Two. The calculator splits this trip into 70 qt food + 75 qt drinks. The drinks cooler is opened constantly and loses ice quickly; keeping food separate means it stays cold because it is only opened at meals.

Will a 150 quart cooler keep ice for 3 days?

Kept in shade at an 85F high and packed at the right ratio, the ice calculator estimates about 3.6 days for this type of cooler, so yes, with margin if you pre-chill it. Real results depend heavily on sun, how warm the contents go in, and how often the lid opens.
