• Target BMI (Advanced Mode):
  • For personalized results, you can enter a target BMI to see the corresponding ideal weight for your goal.
• View Results:
  • The calculator will display your ideal weight values according to multiple formulas, your healthy BMI weight range, and a detailed graph for easy visualization.

What’s a Healthy Weight Range?

A healthy BMI typically falls between 18.5 and 24.9. The calculator provides the minimum and maximum weight required for your height to fall within this range.

Formulas Used in the Calculator

The Ideal Weight Calculator employs seven scientifically recognized formulas to provide a range of ideal weight values:

• Peterson Formula: A modern formula that considers lean body mass and body fat distribution.
• Miller Formula: Emphasizes body proportions to estimate an aesthetically ideal weight.
• Robinson Formula: Adjusts weight calculations based on height to align with BMI standards.
• Devine Formula: Widely used in medical settings, especially for determining dosages based on ideal weight.
• Hamwi Formula: One of the earliest formulas, designed for quick estimations, often used in clinical practice.
• Broca Formula: A classic method, particularly popular in European medical guidelines, which simplifies weight calculations.
• Lorentz Formula: Incorporates age as a factor for more personalized ideal weight estimations.

Why It’s Important

For a male, 183 cm (6 ft) tall and weighing 80 kg (176 lbs):

• Peterson Formula: 74 kg (163 lbs)
• Miller Formula: 73 kg (161 lbs)
• Robinson Formula: 75 kg (165 lbs)
• Devine Formula: 78 kg (172 lbs)
• Hamwi Formula: 81 kg (178 lbs)
• Broca Formula: 83 kg (183 lbs)
• Lorentz Formula: 75 kg (165 lbs)

Healthy weight range based on BMI: 62 kg (137 lbs) to 83 kg (183 lbs).

In advanced mode, targeting a BMI of 25, the ideal weight (Peterson Formula) adjusts to 84 kg (185 lbs).
