Finding Your Ideal Body Weight
Ideal weight calculations provide target ranges based on height, gender, and frame size. CalcSolver's ideal weight calculator uses multiple established formulas — Devine, Robinson, Miller, and Hamwi — to give you a range rather than a single number, since individual variation is significant.
For a 175cm male, the Devine formula suggests 70.3kg, Robinson suggests 67.5kg, and Miller suggests 70.0kg — a target range of roughly 67-72kg. For a 165cm female, the range is approximately 54-59kg across these formulas. Frame size (small, medium, large) shifts the range by ±10%.
Ideal weight is a starting point, not an absolute goal. Consider your body composition, activity level, and personal health history. Athletes may weigh more than "ideal" due to muscle mass. Focus on sustainable habits rather than chasing a specific number. Check your BMI with CalcSolver's BMI calculator and body fat with the body fat calculator.

Frequently Asked Questions
How is ideal body weight calculated?
This calculator uses multiple formulas (Hamwi, Devine, Robinson, Miller) to estimate ideal weight based on height and sex. Each formula gives a slightly different result, providing a healthy weight range.
Which formula is most accurate?
No single formula is perfect for everyone. The Devine formula is most commonly used in medical settings. Our calculator shows results from multiple formulas so you can see a reasonable range.
Does ideal weight account for body frame size?
Basic formulas do not account for frame size. People with larger frames may weigh more than the formula suggests and still be healthy. Use BMI and body composition alongside ideal weight estimates.
