Ideal height and BMI for 68 kg adults
68 kg is a healthy weight if you're between 165 cm and 191 cm tall (a BMI of 18.5 to 24.9).
If you're shorter than 165 cm, 68 kg gives you a BMI of 25 or more. If you're taller than 191 cm, your BMI is under 18.5.
Over means overweight. Under means underweight.

What it means
A healthy weight fits a range of heights. At a given weight, your BMI goes down as your height goes up. The heights in your answer are the ones that give a BMI of 18.5 to 24.9.
We don't round BMI up. We show BMI to one decimal place and drop the rest instead of rounding. So 24.96 shows as 24.9 and still counts as a healthy weight.
BMI doesn't tell the whole story. BMI doesn't account for muscle, bone, age or sex. Two adults with the same BMI can have different health.
How BMI works
- BMI is your weight divided by your height squared. If you use pounds and inches, multiply the result by 703.
- For the most accurate number, weigh yourself in the morning and measure your height without shoes.
- Your category comes from the BMI with the extra decimals dropped, not rounded.
