A 20- to 25-quart cooler is plenty for two people on a weekend.

Yes, that size range handles food and drinks for two adults for a weekend trip without forcing you to pack like a Tetris champion.

Here’s the math: a 20-quart cooler fits about a dozen cans plus a small bag of ice and some sandwiches or leftover chili. For two people, that’s Saturday lunch and dinner plus Sunday breakfast and lunch. If you’re cooking simple stuff—pre-marinated meats, veggies, cheese, eggs—you’ll still have room for a six-pack and a bottle of wine.

Go bigger if you’re bringing a ton of drinks or planning to keep ice for three days straight. But for a standard Saturday-to-Sunday trip, a 25-quart roto-molded cooler (like a Yeti Roadie 24 or a cheaper Igloo equivalent) is the sweet spot. Bigger coolers get heavy fast, and you don’t want to lug a 50-quart behemoth just because you packed one extra bag of ice.

Don’t overthink it. 20 to 25 quarts. Done.
