Body Water Percentage: What Is Normal?

Body water percentage: what is normal?

Body water is the share of your weight that is water. It varies with age, sex and fitness.

Short answer

Total body water is commonly given as roughly 45 to 60 percent of body weight in adults, and it is usually lower in people with more body fat and in older adults. Ranges differ between sources, and hydration changes the reading from day to day. Use the trend over several scans rather than one number, and see a doctor for any health question.

Typical ranges

Many sources put total body water at about 50 to 65 percent for men and 45 to 60 percent for women. Fat holds less water than muscle, so more body fat usually means a lower percentage.

What changes the reading

Hydration, food and drink before the scan.
Training, sweat and heat.
Time of day.
Body fat and muscle mass.

Inside and outside the cells

Some analyzers split water into intracellular and extracellular water. Not every device reports this, so check what the manufacturer states.

Getting a steady reading

Scan at a similar time of day, with similar food and drink, and without hard training just before. Reports are for reference, not a medical diagnosis.
