Introduction
The number of water bottles in a gallon depends on the size of the bottle. If you use a standard 16.9-ounce bottle, you need 7.5 bottles to make a gallon. If small 8-ounce bottles are used, it takes 16 to equal one gallon.
If the bottle is big then you need a small amount of bottles to reach a gallon. In this article, we will explore all the information you need.
Understanding the Basics: What is a Gallon?
A gallon is a unit mainly used for measuring liquid volume. It is mostly used in the United States and some other countries. It’s used in both the US and the imperial measurement systems. People usually use gallons to measure big amounts of liquids like fuel, water, and milk.
Types of Gallons: US vs Imperial
- US Gallon: The US gallon is the standard gallon used in the United States which contains 128 fluid ounces.

How Many 8-Ounce Bottles of Water in a Gallon?
An 8-ounce water bottle is smaller and is also known as a child-sized water bottle. To calculate how many 8-ounce bottles are in a gallon, you can simply divide 128 ounces by 8 ounces: 128 ÷ 8 = 16
So, you would need 16 bottles of 8 ounces to make up one gallon of water.
How Many 12-Ounce Bottles of Water in a Gallon?
A 12-ounce water bottle is a bit bigger than the smaller 8-ounce bottle. This is usually used for single servings of drinks like soda and water. Here’s how to calculate: 128 ÷ 12 = 10.67
This means that you would need approximately 10.67 bottles of 12-ounce water to equal one gallon.
How Many 16.9-Ounce Bottles in a Gallon?
The 16.9-ounce (500 ml) bottle is one of the most common sizes for bottled water. Most people know this size because it’s the most common plastic water bottle you find in stores. Let’s check how many bottles are needed to make a gallon: 128 ÷ 16.9 ≈ 7.57
Thus, it would take about 7.57 bottles of 16.9 ounces to make one gallon of water.
How Many 20-Ounce Bottles in a Gallon?
Some people like to buy bigger 20-ounce bottles. To see how many of these bottles equal a gallon, we can use the same method: 128 ÷ 20 = 6.4
