Understanding BMI Ranges & Ideal Body Weight Definition
A BMI of between 20 and 25 is considered to be an ideal weight. The ideal body weight definition represents the optimal weight range for health outcomes based on your height. You can use this table to determine your acceptable weight range for your height (in cm), by finding the weight corresponding to a BMI level of 20 and 25. For example, if you are 160cm tall, your ideal weight range is between 51.2 and 64.0 kg, and you are obese if you are above 76.8 kg.
Ideal Body Weight Formula Explained
Our calculator uses the scientifically proven ideal body weight formula: BMI = weight(kg) / height(m)². For optimal health:
- Women: BMI 20-23 (Formula: 20-23 × height² = ideal weight range)
- Men: BMI 22-25 (Formula: 22-25 × height² = ideal weight range)
- General population: BMI 20-25 for standard health guidelines
Gender Differences - Ideal Body Weight Calculator Female vs Male
Women - Optimal BMI 20-23
- Body composition: 20-25% body fat naturally
- Ideal range: Lower end of BMI scale
- Muscle distribution: Less muscle mass than men
- Health focus: Bone density and hormonal balance
Men - Optimal BMI 22-25
- Body composition: 10-15% body fat typically
- Ideal range: Higher end of BMI scale
- Muscle distribution: Greater muscle mass and bone density
- Athletic note: May exceed BMI 25 with low body fat
Most Common Height Ranges
Popular Female Heights:
- 160cm females: Perfect weight 51.2-64.0kg (optimal: 55-58kg)

Specialized Applications
Medical professionals note:
- Ideal body weight Ventilator settings: Medical staff use IBW for ventilator tidal volume calculations (6-8ml/kg IBW)
- Ideal body weight pediatric formula: For children, consult pediatric growth charts as standard adult BMI formulas don't apply under age 18
- Clinical dosing: Many medications are dosed based on ideal body weight rather than actual weight
