How Many Bottles of Water Is a Gallon?

Staying Hydrated the Right Way
You may have heard that for proper hydration, aim to drink a gallon of water per day. While this will vary based on individual size, exertion, weather conditions, and more, it still offers a goal post to aim for in your daily water intake.

If you’re not lugging around a gallon-sized jug of water, or a Rambler® Gallon Jug, how many times would you need to refill your bottle to hit that goal? Whether you’re tracking hydration, prepping for a long hike, or just trying to drink more water, knowing how many bottles make up a gallon keeps things simple.

Here’s the fast answer, plus an easy conversion guide and the best YETI Bottles to help you stay on track.



How Many Bottles of Water Are in a Gallon?


The Quick Answer


  • 1 U.S. gallon = 128 fluid ounces
  • 1 Rambler® 18 oz Bottle (18 oz) = about 7 fill-ups to a gallon

Breaking It Down by Common Bottle Sizes
