Calculate BMI

Body Mass Index Explained

BMI, or Body Mass Index, is a number that tells us about our body size compared to our height.

It helps us see if we’re underweight, normal weight, overweight, or obese.

Even though it’s helpful for a quick look at our body, it doesn’t know the difference between muscles and fat, so it’s not perfect.

People often use it with other health checks to get a better picture of how healthy they are.

BMI Ranges for Adults

These BMI range categories give a general idea of where someone might fall based on their BMI:

BMI RangeCategory

18.5 to 24.9Normal Weight
25.0 to 29.9Overweight
30.0 and aboveObesity

However, it’s crucial to note that BMI has limitations and doesn’t consider factors like muscle mass or distribution of fat.

Individual health should be assessed holistically, and BMI should be used as part of a broader health evaluation.
