Healthy Weight Calculator

What weight range is healthy for your specific height, age, and gender? This calculator uses BMI guidelines and additional adjustments to give you a personalized healthy weight range — not just a single target number.

How to Use This Calculator

  1. Enter your height (in feet/inches or cm).
  2. Enter your age and gender.
  3. Click Calculate to see your healthy weight range, BMI category for your current weight, and how far you are from the healthy range.

How Healthy Weight Is Determined

The widely used standard: a healthy weight corresponds to a BMI of 18.5–24.9.

Formula: Weight (kg) = BMI × Height² (m²)

Healthy weight range = BMI 18.5 × h² to 24.9 × h²

Example: Height 5'6" (167.6 cm = 1.676 m)

  • Lower bound: 18.5 × 1.676² = 18.5 × 2.809 ≈ 52.0 kg (115 lbs)
  • Upper bound: 24.9 × 1.676² ≈ 69.9 kg (154 lbs)
  • Healthy weight range for 5'6": 115–154 lbs

Important Considerations

  • The BMI-based healthy range is a guideline, not an absolute. Highly muscular individuals may be "overweight" by BMI while having excellent health.
  • For older adults (65+), research suggests a slightly higher BMI (23–27) may be associated with better outcomes than for younger adults.
  • Different ethnic populations have different risk profiles at similar BMIs (Asian populations face increased cardiometabolic risk at lower BMIs).

Common Mistakes to Avoid

  • Setting goal weight at the very bottom of the range — The lower end of the healthy range may be difficult to maintain and isn't necessarily healthier than the middle. Pick a sustainable target in the middle.
  • Ignoring other health markers — Blood pressure, cholesterol, blood sugar, and waist circumference matter alongside weight. A person at "healthy" BMI with poor markers isn't truly healthy.

Conclusion

A healthy weight is a range — not a single number. Use this calculator to find your range, pick a sustainable target within it, and focus on the habits (nutrition, exercise, sleep) that will get you there and keep you there.

These ranges are for adults. For children and adolescents, healthy weight is determined using BMI-for-age percentiles. Muscle mass and bone density also significantly influence "ideal" weight.
