Best Water Bottle Sizes for Different Activities

Knowing what the water bottle’s purpose will be, will help you identify the right size for you. For example, you wouldn’t carry a 16 ounce small bottle for a long hiking trip.

Best Bottle Size for Kids

Kids need a lot of water especially if they are at school or doing some physical activities, such as running, jogging, or just playing in the school grounds. However, they will not bring a liter of water or something that is hard to hold. So, a 10 ounce - 14 ounce insulated water bottle is a good choice. They can easily refill it whenever they need to. 

This size water bottle is easy to bring and use. It will be easy for them to hold because it is small or slim and usually comes with a handle. They can also choose between beautiful colors and tones.

If you just need water for your daily job or exercises, you may opt for a 16 - 20 ounce water bottle. This size is not so heavy even when it is full. Though a 16-ounce bottle may seem small, it is still enough to keep you hydrated. It is the perfect size for your daily activities without needing to refill so often. 

An 18-ounce stainless steel water bottle might be a better fit. The extra couple of ounces and range of options at this size make it a great fit for every day use.

If you really need to bring a water bottle everyday, you may choose a reusable water bottle to minimize the disposal of plastic bottle wastes.

A 20-ounce stainless steel water bottle is a perfect example of reusable, sustainable, and durable water bottles. In the long run, you will save more money if you prefer to bring your own water bottle every day instead of buying it.
