Ideal weight calculator: how much should I weigh?
The honest answer is a range, not one number. Enter your height and see the weight recommended for you. For women and men, no sign-up.
53–70 kg
the weight that gives a BMI of 18.5–24.9
There is no single “ideal” number: a healthy weight is a range, and where you sit in it depends on muscle, frame and how you feel. This range is the same for women and men and doesn't change with age (for adults).
Old “ideal weight” formulas
- Devine (female): ≈ 60 kg
- Robinson (female): ≈ 59 kg
The Devine formula (1974) was made to work out medicine doses, not how much you “should” weigh. We show it as a curiosity only – the range above matters more for health.
Recommended weight by height: table
| Height | Recommended weight (BMI 18.5–24.9) |
|---|---|
| 150 cm | 42–56 kg |
| 155 cm | 45–59 kg |
| 160 cm | 48–63 kg |
| 165 cm | 51–67 kg |
| 170 cm | 54–71 kg |
| 175 cm | 57–76 kg |
| 180 cm | 60–80 kg |
| 185 cm | 64–85 kg |
| 190 cm | 67–89 kg |
| 195 cm | 71–94 kg |
| 200 cm | 74–99 kg |
The table is the same for women and men. It is for adults; it doesn't apply in pregnancy or to children.
Why not one “ideal” number
Two people of the same height can both be healthy 10 kg apart: one has more muscle, the other a bigger frame. So we show a range. Your waist says more about health – you can add it in the BMI calculator or the body fat calculator.
If you want to reach a different weight, check your calorie needs and read how much you can realistically lose in a month.
Frequently asked questions
How much should I weigh for my height?
For adults the recommended weight is a range, not one number: the weight that gives a BMI of 18.5–24.9. For 170 cm that is roughly 54–71 kg.
What is the ideal weight for women and men?
By BMI the range is the same for women and men of the same height. Where you sit in it depends on muscle, frame and how you feel. Old formulas (like Devine) give women and men different numbers, but they were made for medicine doses, not health goals.
Does ideal weight change with age?
For adults the range doesn't change with age. Later in life, keeping muscle and strength matters more than the number. For children and teenagers (under 18), weight is judged on growth charts – with a doctor.
What if I weigh more or less than that?
Nothing urgent. If you want to change your weight, start with the calorie calculator and a slow pace. If you're losing weight without trying, see a doctor.
