How to Use Our Water Intake Calculator

Proper hydration affects everything from energy levels to cognitive function. Our Water Intake Calculator gives you a personalized daily water target.

What to Enter

  • Body Weight -- Heavier individuals need more water. The baseline formula is roughly half your body weight in ounces.
  • Activity Level -- Exercise increases water needs significantly. Add 12-20 ounces for every 30 minutes of exercise.
  • Climate -- Hot and humid environments increase water loss through sweat.

Understanding Your Results

The calculator provides your recommended daily intake in:

  • Ounces -- The standard US measurement
  • Liters -- For international reference
  • Cups -- The most practical measuring unit

A general baseline is 64 ounces (8 cups) per day, but individual needs vary widely. A 200-pound active person in a hot climate may need 100+ ounces.

Hydration Tips

Drink before you are thirsty. Thirst is a lagging indicator -- by the time you feel thirsty, you are already mildly dehydrated.

Check your urine color. Pale yellow indicates good hydration. Dark yellow means drink more.

Water-rich foods count. Fruits, vegetables, and soups contribute to your daily intake. You do not need to get 100% from drinking water.
