Frequently Asked Questions

What is a healthy weight for my height?

A healthy weight is the range that puts your BMI between 18.5 and 24.9. The calculator converts that BMI band into a pounds/kilograms range for your specific height.

How is the healthy weight range calculated?

It uses weight = BMI Γ— height in metres squared, solved at BMI 18.5 (lower bound) and 24.9 (upper bound), so you see the full healthy range rather than a single number.

Is BMI-based healthy weight accurate for everyone?

It is a useful guide for most adults but does not separate muscle from fat. Very muscular people, older adults and some ethnic groups may have a healthy weight slightly outside the standard band.

What if my weight is outside the healthy range?

Use it as a starting signal, not a diagnosis. Pair it with waist size and a chat with a healthcare professional before making big changes.
