Canoz
BMI calculator
Enter your height and weight to see your body mass index (BMI) and the weight range the World Health Organization calls healthy for your height.
How BMI is calculated
BMI is your weight in kilograms divided by the square of your height in meters. The World Health Organization uses these ranges for adults: under 18.5 is below the healthy range, 18.5 to 24.9 is healthy, 25 to 29.9 is above it and 30 or more is well above it.
What BMI does not show
BMI cannot tell muscle from fat or see where fat sits, so people with a lot of muscle often score high. It is a quick screening number, not a diagnosis. For children and teenagers, doctors use charts by age and sex instead.
Your healthy weight range
The healthy range for your height is every weight that gives a BMI from 18.5 to 24.9. The Canoz app uses the same lower limit: a weight-loss target never goes under a BMI of 18.5.
From a number to a daily habit
If you want to change your weight, the calorie calculator shows how many calories a day fit your goal, and Canoz helps you keep to it when you take a photo of each meal.
