A 70-quart cooler is the sweet spot for two people on a week-long road trip.

Yes, that’s the size that balances capacity and portability.

Here’s why: You’re carrying drinks (heavy, take up space) and perishables for seven days. A 50-quart cooler will be tight — you’ll either run out of room for ice or for food. A 100-quart is overkill for two people and will be a pain to haul in and out of the car.

At 70 quarts, you can fit a 20-pound bag of ice, a few gallons of drinks, and enough food for a week (meat, cheese, produce) without cramming. You’ll still need to buy ice every 2-3 days unless you have a high-end rotomolded cooler that holds ice for 5+ days. But for a standard cooler (Coleman, Igloo, etc.), plan on ice runs.

If you’re in a pickup or SUV with room, bump to 80 quarts for extra margin. If you’re in a sedan, 70 is fine.

Don’t overthink it. 70 quarts. Go.
