Ideal Weight
Several formula estimates from height.
Loading tool
Devine, Robinson, and BMI-band estimates often disagree. None of them knows your sport, bone, or health history.
How to use this tool
- Enter your measurements. Use the units shown on the labels. Do not send medical data anywhere.
- Read the estimate. These formulas are public rules of thumb, not a diagnosis.
- Talk to a clinician for decisions. Do not change medicine, diet, or training from this page alone.
Formulas
These equations were built for narrow clinical or dosing contexts. They are shown together so you can see the spread. They are estimates, not targets.
Frequently asked
Which formula is 'right'?
None universally. A clinician may use one for drug dosing and another for screening.
Should I lose weight to match this?
This page cannot say. That is a medical decision.
Are pediatric formulas included?
No.
Is an 'ideal' weight a prescribed target?
No. The formulas are historical estimates, not medical advice.
Can I switch units?
Yes. Kilograms and pounds.
