BMI Calculator
Our BMI calculator for females is tailored to provide accurate insights into your health.
Enter your height and weight to quickly calculate your BMI and understand where you fall in the BMI range.
Results
Once you input your data, the results will highlight your BMI category (underweight, normal, overweight, or obese). This categorization helps assess potential health risks.
What is BMI?
Body Mass Index (BMI) is a numerical value derived from height and weight.
It serves as a general indicator of body fat levels and potential health risks associated with being under or overweight.
While BMI is a universal tool, it is particularly valuable for women to monitor health goals and prevent risks linked to imbalanced weight.
BMI Table for Adults
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal weight |
| 25 – 29.9 | Overweight |
| 30 and above | Obese |
BMI Table for Children and Teens (Age 2-20)
BMI categories for children and teens are based on age and sex-specific percentiles. Below is a general guide to understanding the BMI ranges:
| BMI Percentile Range | Category |
|---|---|
| Under 5th percentile | Underweight |
| 5th – 84th percentile | Healthy weight |
| 85th – 94th percentile | Overweight |
| 95th percentile and above | Obese |
BMI Chart for Children and Teens (Age 2-20)
The BMI chart for children and teens uses percentiles to account for age and gender. Here’s how to interpret the chart:
| Age | Underweight | Healthy Weight | Overweight | Obese |
|---|---|---|---|---|
| 2-5 years | Below 5th percentile | 5th – 84th percentile | 85th – 94th percentile | 95th percentile and above |
| 6-19 years | Below 5th percentile | 5th – 84th percentile | 85th – 94th percentile | 95th percentile and above |
Risks Associated with Being Overweight
- Increased risk of heart disease.
- Higher likelihood of developing Type 2 diabetes.
- Joint pain and mobility issues.
- Elevated blood pressure and cholesterol levels.
Case Study:
A 35-year-old woman with a BMI of 32 managed to reduce her BMI to 25 over six months through a tailored exercise and diet plan, significantly lowering her risk of hypertension.
Risks Associated with Being Underweight
- Nutritional deficiencies leading to weakened immunity.
- Increased risk of osteoporosis.
- Difficulty in maintaining muscle mass.
Case Study:
A teenage girl with a BMI of 16.5 introduced a balanced diet and nutrient supplementation, improving her BMI to a healthy range within four months.
Limitations of BMI
- Fails to distinguish between muscle and fat.
- Doesn’t account for fat distribution.
- May not apply accurately to athletes or pregnant women.
BMI Formula
BMI is calculated using the formula:
BMI = weight (kg) ÷ height² (m²)
Example Calculation:
A woman weighing 70 kg with a height of 1.65 meters:
BMI = 70 ÷ (1.65 × 1.65) = 25.7
BMI Prime
BMI Prime normalizes BMI relative to the upper limit of the “normal weight” category (25).
Formula: BMI Prime = BMI ÷ 25
Ponderal Index
An alternative to BMI, the Ponderal Index adjusts for height more effectively.
Formula: Ponderal Index = weight (kg) ÷ height³ (m³)
