How big a cooler do 1 person need for 5 days?

Food for 1 person over 5 days takes about 6 quarts at 1.25 quarts per person per day. At three canned drinks each per day, drinks add 7 quarts (15 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 39 quarts.

For this trip length, a rotomolded cooler (or a 12V fridge, or a planned ice run) is worth it.

How do you keep ice for 5 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 rotomolded cooler at an 85F high in shade, the ice calculator estimates about 6 days of ice for a 40 quart cooler. That covers the trip with some margin.

Frequently asked questions

How much ice for 1 person over 5 days?

At the 2:1 ice to contents ratio that suits 5 days, plan about 31 lb of cubed ice across your coolers, roughly 4 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 1 person use one cooler or two for 5 days?

One cooler of about 40 quarts handles this trip. If your group drinks a lot of canned drinks, a small separate drinks cooler still helps, because every opening of the food cooler lets cold air out.

Will a 40 quart cooler keep ice for 5 days?

Kept in shade at an 85F high and packed at the right ratio, the ice calculator estimates about 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.
