How BMI Calculator works

Calculate BMI, category and an estimated healthy weight range. The calculator uses a transparent formula and keeps the calculation in your browser.

BMI = weight (kg) ÷ height² (m²).

Enter realistic values, calculate, then review the formula and supporting statistics shown with the result.

A calculator gives an estimate based on its assumptions. Real-world outcomes can differ because inputs and circumstances change.

BMI is a screening measure based on height and weight. It does not diagnose health conditions and should be interpreted with other factors.

Are calculator results exact?

They are estimates based on the selected formula and the values you enter.

Does the website send my calculation to a server?

The calculator logic runs in your browser and does not require an external calculation API.
