About the Healthy Weight Calculator
What is the Healthy Weight Calculator?
A healthy weight calculator gives a healthy weight range for your height based on the BMI band, plus ideal-body-weight estimates from several classic formulas.
Why use this calculator?
Formulas differ because they were built for different populations. Seeing the range helps you set realistic goals rather than a single magical number.
How to use it
- Select your gender and enter your height.
- The BMI band shows the healthy range for your height.
- Compare the classic formulas below for reference.
Formula
Healthy range = BMI 18.5–25 × height(m)\u00b2
These formulas estimate healthy weights, not appearance ideals. Frame size and muscle mass change the picture.
Frequently Asked Questions
Which formula is most accurate?
None is perfect; they were derived from small samples decades ago. The BMI range is the most defensible general target.
What about people with more muscle?
Muscular people can sit above the healthy weight range while still being lean. Focus on body fat and waist circumference there.
Is this a medical diagnosis?
No. This tool provides general wellness information only. It is not a substitute for evaluation by a qualified healthcare professional.
Why do results differ from my doctor's measurements?
Clinical measurements use calibrated equipment and professional technique. Home estimates rely on formulas and self-reported values, so small differences are normal.
How often should I recalculate?
Recheck after meaningful changes such as weight gain or loss, a new workout routine, or every few months to track trends over time.
Do these formulas apply to everyone?
Most population formulas are less accurate for athletes, pregnant people, very young children and the elderly. Use them as a general guide.
