How many ounces in a water bottle?

While the size of water bottles can vary significantly, the following are some of the most common capacities found on the market:
• 12 oz (355 mL): This smaller size is ideal for kids or for carrying lightweight, portable bottles in small bags. It is typically used for short excursions, where a large amount of water isn’t necessary. Some insulated water bottles of this size are great for keeping beverages like coffee hot for hours.
• 17 oz (500 mL): This is a popular size for many consumers who prefer a balance between portability and sufficient hydration. Many insulated bottles, including those designed for gym-goers or for everyday carry, fall within this range.
• 20 oz (600 mL): Slightly larger than the 17 oz bottle, this size offers more capacity without becoming too bulky. It’s a great option for those looking for a bit more hydration during workouts or daily activities.
• 24 oz (710 mL): This mid-sized option is favored by many for its ability to hold more water while still being easy to carry around. Bottles in this range are often used for hiking, fitness activities, and long commutes.
• 32 oz (1,000 mL or 1 liter): A 32 oz bottle is perfect for people who need to stay hydrated over long periods, such as during a workday or extended outdoor activity. It’s often chosen by athletes and fitness enthusiasts because of its larger capacity. Many insulated bottles of this size can keep water cold for up to 24 hours.
• 40 oz (1.2 liters): This larger size is ideal for those who want to carry a substantial amount of water or other beverages. It is often used for all-day hydration without the need for frequent refills and is popular in insulated bottles due to its ability to maintain beverage temperatures for long periods.
• 64 oz (1.9 liters): This extra-large size is often marketed as a “half-gallon” bottle and is typically used by athletes or those aiming for high hydration throughout the day. This size is also ideal for outdoor activities like camping or long hikes where access to water might be limited. Some brands also offer this size with handles to make it easier to carry.
