About BMICheck

BMICheck is a small, free tool for calculating Body Mass Index from your height and weight, in either metric or imperial units. It shows the standard WHO weight category and the healthy weight range for your height, without asking for an account, a payment, or your data.

Everything happens in your browser using the standard BMI formula — your input is never sent to a server or stored anywhere. BMI is a quick screening tool, not a diagnosis; see the calculator page's FAQ for its limits.

BMICheck is supported by ads shown alongside the tool, which keeps it free to use with no limits. It's one of a growing set of small tools at Laborilo.
