What should you weigh for your height and sex?
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.
Sex
The "ideal weight" is a statistical reference: it ignores muscle mass and frame. A healthy range matters more than an exact number.
That number is only today
In the app you watch it move: weigh-ins, progress photos and the trend of the last weeks in one chart.
Start tomorrow: weigh yourself when you get up, before breakfast, and photograph the first plate of the day.

How is ideal weight calculated?
The classic formulas (Devine, Robinson, Miller and Hamwi) estimate a reference weight from your height and sex. None of them knows anything about your build, your muscle mass or your health — they were built decades ago for drug dosing, not for body composition. That is why this calculator shows you all four side by side instead of pretending there is one right answer: the spread between them is the honest margin. We add the WHO healthy weight range for your height, which is wider and usually more useful. Treat the result as a reference band, not a target you owe anyone.
Ideal weight by height, from 1.50 to 1.90 m
Two answers to the same question. The men and women columns are the average of the four classic clinical formulas (Devine, Robinson, Miller and Hamwi), which do separate the sexes; the last one is the weight range for a healthy BMI, the same for everyone. That this column is a wide band rather than a number is the point: there is no single "ideal weight".
| Height | Men | Women | Healthy range (BMI) |
|---|---|---|---|
| 1.50 m | 49.6 kg | 46.5 kg | 41.6 – 56.0 kg |
| 1.55 m | 53.7 kg | 50.2 kg | 44.4 – 59.8 kg |
| 1.60 m | 57.8 kg | 53.9 kg | 47.4 – 63.7 kg |
| 1.65 m | 61.9 kg | 57.7 kg | 50.4 – 67.8 kg |
| 1.70 m | 65.9 kg | 61.4 kg | 53.5 – 72.0 kg |
| 1.75 m | 70.0 kg | 65.1 kg | 56.7 – 76.3 kg |
| 1.80 m | 74.1 kg | 68.8 kg | 59.9 – 80.7 kg |
| 1.85 m | 78.2 kg | 72.5 kg | 63.3 – 85.2 kg |
| 1.90 m | 82.3 kg | 76.3 kg | 66.8 – 89.9 kg |
Computed with the same function as the calculator: average of the Devine (1974), Robinson (1983), Miller (1983) and Hamwi (1964) formulas, and the BMI 18.5 to 24.9 range of the WHO classification. These are reference ranges for healthy adults, not a diagnosis or individual advice.
FAQ
What is my ideal weight for my height?
It also depends on sex. With the four classic clinical formulas, a 1.75 m man comes out around 70.0 kg and a 1.65 m woman around 57.7 kg. But a healthy weight is a range: at 1.75 m, from 56.7 to 76.3 kg, and at 1.65 m, from 50.4 to 67.8 kg.
How much should I weigh at 1.60, 1.70 or 1.80 m?
By the clinical formulas, a 1.60 m woman comes out around 53.9 kg and a man around 57.8; at 1.70 m, 61.4 and 65.9 kg; at 1.80 m, 68.8 and 74.1 kg. Any weight inside the healthy-BMI range in the chart is just as healthy.
Is ideal weight the same as a healthy weight?
Not quite. "Ideal weight" is a statistical number from a formula; a healthy weight is a range where your health markers, energy and relationship with food all work. The WHO range shown underneath is the better guide of the two.
Why does my ideal weight look low if I train?
Because the formulas cannot tell muscle from fat. If you carry a decent amount of muscle you will sit above your "ideal" weight while being leaner and healthier than someone at it. Use body fat percentage or waist measurements instead.
How long does it take to reach it?
It depends on how many kilos stand between you and it, and it is not a division. Dividing, 10 kg at 0.5 kg a week would be 20 weeks; with expenditure recalculated every week and the calorie floor of the weight loss calculator, a lightly active 34-year-old woman of 165 cm and 85 kg takes about 27 weeks, and a 34-year-old man of 178 cm and 95 kg about 22. With your own numbers, that calculator gives you your week.
