Ideal weight calculator

Ideal weight (Robinson) 71.1 kg

Healthy range (BMI 18.5-25): 58.6 kg – 79.2 kg

“Ideal weight” is only a rough guide: it doesn't account for muscle mass or body frame. The healthy BMI range is usually more useful. Not medical advice.

This ideal weight calculator gives you your ideal weight using the Robinson formula and the healthy weight range based on your height (BMI 18.5-25).

The healthy range matters more

Rather than a single number, what’s actually useful is the healthy weight range for your height. A weight within that range is associated with lower risk, though body composition matters more than the figure itself.

This is only a guide — it does not replace advice from a health professional.

FAQ

How is ideal weight calculated?

We use the Robinson formula (based on sex and height) plus the weight range that corresponds to a healthy BMI (18.5-25), which tends to be more realistic.

Is ideal weight reliable?

It's only a guide. It doesn't distinguish muscle from fat or account for body frame, so a very muscular person can be above the range without having excess fat.

What does the healthy range mean?

It's the weight span that corresponds to a BMI between 18.5 and 25 for your height — generally considered a lower-risk range for adults.
