Ideal Weight Calculator
Estimate your ideal body weight based on height and gender using the Devine Formula.
Historically, medical professionals have used "Ideal Body Weight" (IBW) formulas to calculate drug dosages and estimate healthy weight guidelines. Our Ideal Weight Calculator uses the Devine Formula (1974), which is the most widely accepted standard for medical use. While no simple calculator can account for frame size or muscle mass, this tool provides a baseline reference point for a healthy weight targets based on your height and gender.

Frequently Asked Questions
Is There Really an "Ideal" Weight?
The concept of an "ideal" weight is a statistical average, not a rigid rule. Calculators like the Devine Formula were originally designed for calculating safe drug dosages (like anesthetics) rather than judging aesthetic or holistic health standards. However, they remain a useful general guideline.
1. The Muscle Factor
These formulas rely entirely on height and gender. They do not account for muscle mass, bone density, or frame size. An athlete with significant muscle mass might be 15-20 lbs heavier than their "ideal" weight yet be in peak physical condition with a low body fat percentage. Use this result as a starting point, not a verdict.
2. Other Healthy Weight Models
Besides the Devine Formula, there are other methods used by doctors:
- Robinson Formula (1983): A revision of the Devine formula that often yields slightly lower values for men.
- Miller Formula (1983): An updated formula that often yields lower values for women.
- Hamwi Formula (1964): A quick "rule of thumb" method (106 lbs for first 5ft + 6 lbs per inch for men, 100 + 5 lbs for women).
3. Better Health Metrics
Instead of fixation on a single scale number, consider tracking these health indicators which often correlate better with longevity:
- Waist Circumference: Excess abdominal fat is a stronger predictor of heart disease than weight alone.
- Body Fat Percentage: The ratio of fat to lean mass is critical.
- Blood Markers: Cholesterol, blood pressure, and blood sugar levels are the true "under the hood" metrics.
4. Frequently Asked Questions (FAQ)
Q: Why is the range for women lower?
Biologically, women tend to have smaller frames and less muscle mass than men of the same height, which is reflected in these formulas.
Q: Does age affect ideal weight?
These specific formulas do not account for age. However, some recent medical research suggests that carrying a little extra weight (within reason) as you age (65+) may actually be protective against frailty.
