BMI Calculator FAQs
BMI (Body Mass Index) is a useful screening tool, but it doesn't directly measure body fat or account for factors like muscle mass, bone density, or overall body composition. It should be used as one of several health indicators.
Generally, a BMI between 18.5 and 24.9 is considered healthy for most adults. However, ideal BMI can vary based on factors like age, ethnicity, and body composition.
Our standard BMI calculator is designed for adults. BMI for children and teens should be calculated using age and gender-specific charts, as their bodies are still developing.
For most people, checking BMI a few times a year is sufficient. More frequent monitoring may be helpful if you're actively working on weight management goals.
If your BMI falls outside the healthy range, consider consulting with a healthcare provider. They can provide personalized advice based on your overall health, lifestyle, and other factors.
