About BMI Calculator
The Body Mass Index (BMI) is a simple screening tool that is widely used to categorize whether a person has a healthy body weight for their height.

Frequently Asked Questions
What is a 'Normal' BMI?
A BMI between 18.5 and 24.9 is considered to be within the healthy or 'normal' weight range. This range is associated with the lowest risk of weight-related health issues.
Is BMI accurate for everyone?
While BMI is a useful general indicator, it has limitations. It doesn't distinguish between muscle mass and fat. Athletes or very muscular individuals might have a high BMI despite having low body fat. Conversely, older adults might have a normal BMI but higher body fat.
How often should I check my BMI?
Checking your BMI once a month is generally sufficient for tracking weight changes. Our tool saves your history locally so you can track your progress over time.
Remember, while BMI is a helpful screening tool, it represents just one aspect of your overall health. Factors like diet, exercise, stress levels, and sleep quality also play crucial roles. Use this calculator as a guide, but always consult with healthcare professionals for comprehensive medical advice.
