| 18.5 – 24.9 | Normal weight |
| 25.0 – 29.9 | Overweight |

| 35.0 – 39.9 | Obese (Class 2) |
| 40.0 and above | Obese (Class 3) |
These categories apply broadly to adults, but the BMI for women focuses specifically on gender-relevant body composition, helping women interpret these numbers in a more personalized way.
Formula Used in BMI Calculator
The BMI is calculated using the following formula:
BMI Formula (Metric Units):
iniCopyEditBMI = weight (kg) / [height (m)]² BMI Formula (Imperial Units):
iniCopyEditBMI = [weight (lb) / height (in)²] × 703 Example Calculation
Let’s see how it works with a real-world example.
Example 1: Using Metric Units
- Height: 165 cm = 1.65 meters
- Weight: 60 kg
- BMI = 60 / (1.65 × 1.65) = 22.04
Result: Normal weight
Example 2: Using Imperial Units
- Height: 5'4" = 64 inches
- Weight: 140 lbs
- BMI = (140 / 64²) × 703 = 24.03
Result: Normal weight
Why BMI Is Important for Women
BMI helps women understand their health status in relation to their weight. It can indicate:
- Risk of cardiovascular disease
- Likelihood of developing diabetes
- Potential hormonal imbalances
- Nutritional deficiencies or excesses
- Need for lifestyle changes or medical follow-up
However, BMI doesn’t measure fat percentage, bone density, or muscle mass, which is why it should be used in combination with other metrics like waist-to-hip ratio or body fat analysis.
When to Use a BMI Calculator
- Before starting a diet or fitness program
- During regular health checkups
- While tracking pregnancy recovery
- For setting realistic weight goals
- To monitor weight-related health risks
Limitations of BMI
- Doesn’t account for muscle mass vs. fat
- May underestimate body fat in older women
- Doesn’t apply well to pregnant or lactating women
- Can misclassify athletes as overweight due to muscle density
Despite its limitations, BMI remains a widely accepted, easy-to-use indicator of health risk.
