How much should I weigh for my height?

Healthy weight ranges vary by formula. The BMI healthy range (18.5–24.9) is widely used: for a 5'7" (170cm) person, this is approximately 54–80 kg. Our calculator provides 4 formula estimates and the BMI range.

Why do the different formulas give different results?

Each formula was developed in different decades and for different medical purposes. They use slightly different base weights and increments per inch above 5 feet. The average of all four is the most balanced estimate.

Is ideal weight the same for men and women of the same height?

No. Men generally have more muscle mass and bone density than women. All four formulas account for this biological difference with separate starting weights and multipliers.

What if I'm naturally heavier than my ideal weight?

Ideal weight formulas are guidelines, not verdicts. Focus on health markers: blood pressure, cholesterol, blood sugar, and fitness level. Weight alone does not determine health.

Can I be overweight by BMI but healthy?

Yes. Athletes with high muscle mass often have a BMI in the 'overweight' range despite having low body fat. This is a known limitation of BMI. Body fat percentage and waist circumference are better indicators.

Часто задаваемые вопросы (FAQ)

What is Ideal Body Weight?

Ideal body weight (IBW) is a clinical estimate of the most healthy weight for a given height and gender. It is used by healthcare professionals for drug dosing, anesthesia, ventilator settings, and general health benchmarking. However, it is not a one-size-fits-all answer.

The 4 Clinical Formulas Compared

Hamwi (1964): The oldest and most commonly referenced. Used in clinical settings worldwide.
Devine (1974): Originally developed for medication dosing. Widely used in pharmacology.
Robinson (1983): A modified Devine formula, producing slightly different results for each gender.
Miller (1983): Generally produces the lowest (lightest) estimate of the four formulas.

IBW vs. BMI vs. Body Fat %

IBW formulas don't account for muscle mass or body composition. A muscular athlete may weigh more than their IBW while having an excellent health profile. Body fat percentage is a more accurate health indicator than weight alone.
