Mathematical Formulas & Calculation Methods

Devine Formula (Clinical Standard)

The most widely used clinical Ideal Body Weight (IBW) formula.

Male IBW (kg) = 50 + 2.3 × (Height in inches - 60) | Female IBW (kg) = 45.5 + 2.3 × (Height in inches - 60)

WHO Healthy BMI Weight Range

Calculates minimum and maximum weight for a normal BMI (18.5 to 24.9 kg/m²).

Min Weight (kg) = 18.5 × (Height in m)² | Max Weight (kg) = 24.9 × (Height in m)²

Worked Step-by-Step Examples

Example 1: Healthy Weight Range for a 5 ft 10 in Male

"Calculate Ideal Body Weight via Devine formula and Healthy BMI range for a 70-inch (177.8 cm) male."

Steps:

Inches over 60: 70 - 60 = 10 inches.
Devine IBW: 50 kg + (2.3 × 10) = 50 + 23 = 73 kg (160.9 lbs).
Height in meters squared: 1.778² ≈ 3.1613 m².
BMI Min (18.5): 18.5 × 3.1613 = 58.5 kg (128.9 lbs).
BMI Max (24.9): 24.9 × 3.1613 = 78.7 kg (173.5 lbs).

Result: Ideal Weight: 161 lbs | Healthy BMI Range: 129 lbs to 174 lbs

What is Healthy Weight Calculator & Range Finder?

A healthy weight calculator is an analytical fitness tool that determines an individual's healthy target body weight based on height, biological sex, and clinical body mass index thresholds.

Exploring a healthy weight range for my height reveals that rather than aiming for a single rigid number, maintaining a weight within a healthy range provides room for muscle mass and body frame variations.

Equations like the devine formula ideal body weight were originally created for clinical drug dosing, but serve as excellent benchmark targets for weight loss or muscle building goals.

Frequently Asked Questions

Which ideal body weight formula is best?

The Devine formula is the standard clinical benchmark, but the WHO Healthy BMI Range offers the most comprehensive target spectrum for general populations.

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

No, male body compositions naturally feature higher bone density and muscle mass ratios, resulting in higher ideal weight values for a given height.
