Your Ideal Weight Range

What Is a Ideal Weight Calculator?

An ideal weight calculator estimates a healthy target body weight from height alone using published clinical formulas. We compute Devine (1974), Robinson (1983), Miller (1983) and Hamwi (1964) — each used historically in dosing, insurance tables and nutrition screening. Results are shown per formula plus a combined min–max range and mean.

Ideal weight ranges help set realistic goals alongside BMI and body composition. Multiple formulas highlight that "ideal" is not a single number — comparing them gives a band rather than false precision.

Frequently Asked Questions - Ideal Weight Calculator

Why do the four formulas give different numbers?

Each study used different populations and regression fits. That is why we show all four plus a range — your clinician may prefer one reference depending on context.

Is ideal weight the same as healthy BMI weight?

They are related but not identical. BMI uses weight and height together; ideal-weight formulas predict weight from height only. Use both with professional advice for goals.
