What is a healthy weight?

A healthy weight is typically defined as a weight that corresponds to a BMI between 18.5 and 25. This range is associated with lower risk of weight-related health conditions.

How is the healthy weight range calculated?

The healthy weight range is calculated by finding the weights that produce a BMI of 18.5 (lower bound) and 25 (upper bound) for a given height, using the formula: weight = BMI × height².

About Healthy Weight

A "healthy weight" is generally defined as a weight that corresponds to a Body Mass Index (BMI) between 18.5 and 25. This range is associated with a lower risk of weight-related health conditions such as heart disease, type 2 diabetes, and certain cancers.

How it's calculated

For a given height in meters, the healthy weight range is:

Lower bound: 18.5 × height²
Upper bound: 25.0 × height²

The overweight range (BMI 25–30) and obesity threshold (BMI > 30) are also shown for reference.

Limitations

BMI-based weight ranges do not account for body composition (muscle vs. fat), age, sex, or ethnicity. Athletes with high muscle mass may fall outside the "healthy" range despite being healthy. For a more complete picture, consider combining this with body fat percentage or lean body mass estimates.

Tips

Measure height without shoes and stand straight against a wall.
This calculator only needs your height — no weight, age, or sex required.
