The amount of water you should drink daily varies by factors such as sex, activity level, environment, and health, but general guidelines exist:

• For men, about 15.5 cups (3.7 liters or roughly 124 ounces) of fluids per day is recommended.
• For women, about 11.5 cups (2.7 liters or roughly 92 ounces) of fluids per day is recommended

These fluid amounts include all beverages and water content in food, with about 20% typically coming from food

. How many water bottles this translates to depends on the bottle size:

• For a standard 16.9-ounce (500 ml) bottled water, this means about 4 bottles per day for an average person following the 8x8 rule, but men may need closer to 7-8 bottles and women about 5-6 bottles to meet the higher recommended intake

• Using larger bottles like 24-ounce or 32-ounce bottles reduces the number needed: women might drink about 3-4 bottles of 32 oz, men about 4-5 bottles

Summary:

• Women: roughly 3 to 6 bottles of water daily depending on bottle size (16.9 oz to 32 oz).
• Men: roughly 4 to 8 bottles daily depending on bottle size.
• Adjust intake based on activity, climate, health, and diet

The traditional "eight 8-ounce glasses a day" (about 2 liters) is a simple guideline but may be insufficient for many adults, especially men or those active or in hot climates

. Therefore, aim for about 2.7 to 3.7 liters of fluids daily, adjusting bottle count based on your bottle size and personal needs.
