Overview

A healthy weight range is calculated from BMI values between 18.5 and 24.9, which the WHO associates with the lowest risk of weight-related health complications. This range gives you a practical lower and upper weight boundary for your height.

Formula & Calculation

Min Weight = 18.5 × Height(m)²
Max Weight = 24.9 × Height(m)²

Example

Height 170cm → Min = 18.5×1.70² = **53.5 kg**, Max = 24.9×1.70² = **71.9 kg**

Healthy Weight Range Calculator: Find Your Lower and Upper Weight Limits

What is the lowest and highest healthy weight for your height? This calculator translates your height into a concrete weight range using WHO BMI guidelines — no generic charts, no guessing.

What Is a Healthy Weight Range?

A healthy weight range is the band of body weights associated with a normal BMI — between 18.5 and 24.9. Within this band, the risk of weight-related conditions like heart disease, type 2 diabetes, and joint problems is at its lowest for most adults.

The Formula

Minimum Healthy Weight = 18.5 × Height(m)²
Maximum Healthy Weight = 24.9 × Height(m)²

Worked Example

Height: 168 cm = 1.68 m. 1.68² = 2.8224

Minimum: 18.5 × 2.82 = 52.2 kg | Maximum: 24.9 × 2.82 = 70.3 kg

That is an 18 kg healthy window for someone 168 cm tall. Find yours with our Healthy Weight Range Calculator.

Why This Matters

  • Clear targets. Concrete lower and upper boundaries replace vague weight loss goals.
  • Evidence-based. Derived from WHO BMI guidelines backed by global research.
  • Progress reference. Useful at any point in a weight management journey.

Limitations

  • BMI-based ranges do not account for muscle mass.
  • Older adults and pregnant women may have different ideal ranges.

Practical Tips

Aim for the middle of your range. Targeting the midpoint leaves room for natural daily weight fluctuation (which can be 1–2 kg).

Use body fat percentage alongside weight. Being inside the range at 30% body fat is not the same as being inside it at 18% body fat.

Final Thoughts

Two numbers. A clear, science-based boundary. Use them as your long-term weight management reference.
