How big a cooler do 4 people need for 4 days?

Food for 4 people over 4 days takes about 20 quarts at 1.25 quarts per person per day. At three canned drinks each per day, drinks add 22 quarts (48 cans). Then ice goes in at 2:1 to the contents, because four days or more is where most coolers run out, and 2:1 is what rotomolded brands recommend. That totals about 125 quarts.

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

How do you keep ice for 4 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 is short of 4 days, so plan a top-up or a cooler with thicker walls.

Keep planning

Frequently asked questions

How much ice for 4 people over 4 days?

At the 2:1 ice to contents ratio that suits 4 days, plan about 100 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 4 people use one cooler or two for 4 days?

Two. The calculator splits this trip into 60 qt food + 65 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 4 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 plan an ice run partway through, or step up to a better-insulated cooler. Real results depend heavily on sun, how warm the contents go in, and how often the lid opens.
