Ideal weight calculator
Find your reference ideal weight in seconds by height and sex. We compute it with the four classic clinical formulas (Devine, Robinson, Miller and Hamwi) and also give you your WHO healthy weight range — usually the most useful part.
Your reference ideal weight

Healthy weight range (WHO): 56.7–76.3 kg

Renzy sets a realistic target and gets you there: photograph your food and watch your progress week by week.
The "ideal weight" is a statistical reference: it ignores muscle mass and frame. A healthy range matters more than an exact number.
How is ideal weight calculated?
The classic formulas (Devine, Robinson, Miller and Hamwi) estimate a reference weight from your height and sex; they were created for drug dosing and give a single ballpark number. We show the average of the four and, above all, your healthy weight range from the WHO BMI (18.5–24.9). No formula accounts for muscle mass or bone frame, so a muscular athlete can exceed "ideal" weight without excess fat. The range matters more than the exact number.
FAQ
What is my ideal weight for my height?
It also depends on sex and frame. As a reference, a 1.75 m man is around 68-72 kg and a 1.65 m woman 57-61 kg. The calculator gives your figure and exact healthy range.
Is ideal weight the same as a healthy weight?
Not quite. "Ideal weight" is a single number from a formula; healthy weight is a range (normal BMI for your height). You can be perfectly healthy anywhere in that range.
Why does my ideal weight look low if I train?
Because formulas do not separate muscle from fat. With significant muscle mass, your healthy weight sits at the top of the range or above — that is normal. Look at body fat percentage instead.
How long to reach ideal weight?
At a healthy ~0.5 kg per week, take the difference and divide by 0.5. Faster loss costs muscle and rebounds. Sustainable wins.
