Frequently Asked Questions

What is a reverse BMI calculation?

Normal BMI takes weight and height and gives a number; reverse BMI takes a target number and height and tells you the weight that produces it.

Which BMI range is considered healthy?

The WHO classifies 18.5-24.9 as healthy weight for adults. This tool is informational only — talk to a healthcare professional about your personal target.

Does it work in pounds?

The formula above is metric (kg, cm). For pounds and inches use: weight (lb) = BMI × height (in)² ÷ 703 — e.g. BMI 22 at 67 in is 22 × 4489 ÷ 703 ≈ 140.5 lb.
