Ideal Weight Calculator
Calculate ideal weight using 4 medical formulas: Hamwi (1964), Devine (1974), Robinson (1983), Miller (1983). Plus healthy BMI range (18.5-24.9) for the same height. These are clinical formulas, not aesthetic targets.

Why the Ideal Weight Calculator is different
Browser-native
The Ideal Weight Calculator runs entirely in your browser. Input is processed locally — never uploaded, never logged, never cached anywhere outside your device.
No artificial limits
No daily quotas, no character ceilings, no "upgrade for more" walls. Every feature is the complete feature — the same on the first use as the thousandth.
Production-grade quality
Built to the same engineering bar as paid SaaS tools — accurate algorithms, audited logic, responsive design and accessibility-tested interactions.
Common use contexts
- Medication dosing reference
- Weight goal-setting (general guidance)
- Curiosity / health awareness
- Comparing your weight vs clinical reference
Private and secure
