How Many Ounces in a Bottle of Water?

When you go to the grocery store to purchase a bottle of water, there’s usually one question that comes to mind: how many ounces does it contain? The answer really depends on the size of the bottle itself. Generally, a standard bottle of water is 16.9 fluid ounces, which is the amount of water typically served in a single-serving bottle. However, bottles come in different sizes and can range from as little as 6 ounces to as large as 33.8 ounces.

Standard Bottle Sizes

When looking at standard bottles of water, 8 oz. and 16.9 oz. are the most common sizes. An 8 oz. bottle of water is generally used for single servings and is considered to be average in size; however, 16.9 oz. bottles are the most common choice for larger sizes, such as for long trips or for a family to share. Understanding how many ounces are in a bottle is important so that you can purchase the proper size for your needs.

Other Bottle Sizes

If you are looking for a larger option, you can find bottles that range in size from 24 oz. to 33.8 oz. These bottles are usually for outdoor activities, such as camping or picnics. You can also find smaller options ranging from 6 oz. to 12 oz., which are generally used for single-serve portions and are more convenient when on the go.


No matter what size you’re looking for, there are a variety of bottle sizes to choose from. From small 6 oz. bottles to large 33.8 oz. bottles, you can always find what you need when it comes to buying a bottle of water. So, when you’re at the store trying to decide which size bottle to get, make sure to pay attention to how many ounces are in each one.
