BMI Calculator Guide
Body Mass Index (BMI) is a simple screening tool to estimate body fat based on your height and weight. It helps categorize individuals into weight groups to assess potential health risks.
Consider an adult with the following measurements:
Health Screening
Quickly identify if you are underweight, normal weight, overweight, or obese.
Track Progress
Monitor your BMI over time to see the effectiveness of diet and exercise plans.
Global Standard
BMI is recognized by WHO and doctors worldwide as a primary health indicator.
Q1: Is BMI always accurate?
Not always. It doesn’t distinguish between muscle and fat. Athletes may have a high BMI despite having low body fat.
Q2: What is a healthy BMI range?
For most adults, a BMI between 18.5 and 24.9 is considered the healthy/normal weight range.
Q3: Can BMI be used for children?
Yes, but the interpretation is different. For children and teens, BMI is compared against age- and gender-specific growth charts (percentiles).
Q4: Should I rely only on BMI?
No. For a complete health assessment, also consider waist circumference, body fat percentage, and consult a doctor.
