BMI Calculator for Women
Welcome to our comprehensive BMI Calculator for Women, designed specifically to address female health and wellness needs across all life stages.
This advanced tool calculates not just BMI, but also provides body fat percentage (BFP) estimation, WHtR (Waist-to-Height Ratio) for abdominal fat evaluation, WHR (Waist-to-Hip Ratio) for body shape assessment, and multiple ideal weight formulas (Hamwi, Devine, Robinson, Miller) tailored for women.
Our calculator uses the following algorithms:
- BMI = weight (kg) / height² (m)
- Body fat estimation (women) = 1.20 × BMI + 0.23 × age - 5.4
- WHtR = waist circumference / height
- WHR = waist circumference / hip circumference
- Ideal weight formulas adapted for female physiology
Additionally, we provide pregnancy and menopause considerations based on your age and BMI, making this tool suitable for women of all ages (18-120 years).

Frequently Asked Questions
What is a healthy BMI for a woman?
According to WHO standards, a healthy BMI range for adult women is 18.5-24.9. However, BMI should be interpreted alongside other metrics like waist circumference, body composition, and overall fitness level. For women over 65, a slightly higher BMI (22-27) may be protective.
How to calculate BMI for female NHS?
BMI calculation is the same for all adults: divide weight in kilograms by height in meters squared (BMI = kg/m²). For imperial units, multiply weight in pounds by 703, then divide by height in inches squared. NHS also recommends considering waist circumference and overall health.
What is my ideal weight for my height and age?
Ideal weight depends on multiple factors including height, body frame, muscle mass, and age. Our calculator provides 5 different ideal weight estimates for women: BMI range (18.5-24.9), and four established formulas (Hamwi, Devine, Robinson, Miller) each adapted for female physiology.
How does age affect BMI for women?
As women age, body composition changes with muscle mass decreasing and body fat increasing. This means a slightly higher BMI may be acceptable for older women (65+). Hormonal changes during perimenopause and menopause also affect weight distribution and metabolism.
What is WHR and why is it important for women?
Waist-to-Hip Ratio (WHR) compares waist and hip measurements to assess body fat distribution. For women, WHR <0.80 indicates low risk (pear shape), 0.80-0.85 moderate risk, and >0.85 high risk (apple shape). Apple-shaped women have higher cardiovascular risk.
How much should a 5'4" female weigh?
For a 5'4" (162.56 cm) woman, healthy weight ranges are approximately 110-145 lbs (50-66 kg) based on BMI 18.5-24.9. Ideal weight formulas give: Hamwi 120 lbs, Devine 120 lbs, Robinson 126 lbs, Miller 129 lbs. Frame size and muscle mass affect ideal weight.
Can you give an example calculation?
Let's calculate for a 35-year-old woman who is 165 cm tall and weighs 65 kg. BMI = 65 / (1.65)² = 65 / 2.72 = 23.9 (normal range). Estimated body fat = 1.20×23.9 + 0.23×35 -5.4 = 28.7 + 8.05 -5.4 = 31.35% (acceptable). WHtR = 80 cm / 165 cm = 0.485 (healthy).
