About these health calculators

Health calculators turn a couple of measurements into a screening number you can track over time. CalcTap explains each metric in plain language, including its limitations, so a number is never mistaken for a diagnosis.

Results are educational. For personal medical guidance — especially for children, pregnancy, athletes, or older adults — speak with a qualified clinician.

Tips for accurate results

  • Use consistent units. Enter height in centimetres in metric mode, and pounds with feet and inches in imperial mode.
  • Track the trend. A single reading matters less than how the number changes across weeks and months.

FAQ

Health calculator questions

BMI does not separate muscle from fat, so very muscular people can show a high BMI despite low body fat. Treat it as a screening indicator rather than a verdict.
Children and teenagers are assessed with age- and sex-specific BMI percentiles. The adult categories shown here do not apply to them.
