50.4–67.9 kg
At 165 cm, the normal weight range is 50.4–67.9 kg
About 165 cm
- Under 50.4 kg is the "underweight" band, a World Health Organization population statistic.
- From 68 kg to 81.5 kg is the "overweight" band, a World Health Organization population statistic.
- Above 81.6 kg is the "obesity" band, a World Health Organization population statistic.
- BMI does not distinguish muscle from fat — a trained athlete often reads as "overweight" on this scale. It does not apply to children, to pregnancy or to the very old.
Examples
What you get
The range, worked out on the spot
Enter your height and get the weights that read as "normal weight", with no steps in between.
All four WHO bands
See the boundaries for underweight, overweight and obesity too, at the same height — not just the normal range.
No need to enter your own weight
The range is worked out from height alone — you do not need to know your own weight to see it.
Nothing is stored
Your height stays on your page. We do not store it or send it anywhere.
How it works
- Enter your height, in centimetres.
- You get the normal weight range for that height, plus the WHO's other three bands.
Worth knowing
What the range shows
The range is the weight at which BMI — weight in kilograms divided by height in metres, squared — falls between 18.5 and 24.9, the "normal weight" band in the World Health Organization's population statistics, at the height entered.
What BMI does not show
BMI does not distinguish muscle from fat, so a trained athlete can weigh more than this range without carrying excess fat. It does not apply to children, to pregnancy or to the very old — for them a healthy weight is worked out differently. The bands above are World Health Organization population statistics, not a verdict about any one person, and not a single target weight either.
Frequently asked questions
Is there one perfect number for me?
No. This is a range, not a single target — the weight span that reads as "normal weight" in the World Health Organization's population statistics for this height.
Does this apply to everyone?
No. It does not apply to children, to pregnancy or to the very old, for whom a healthy weight is worked out differently.
Does it account for muscle?
No. BMI does not distinguish muscle from fat, so a very fit person can weigh more than this range without excess fat.
Why is the range wider at a greater height?
Because the BMI formula divides by height squared. The taller the height, the less a single kilogram changes the result, so the weight span between the same two BMI cut-offs grows wider.
