Average Weight Of 5'9 Female — UK Healthy Weight Guide
If you're 5'9 (175cm) tall, the average UK weight for adult women of this height is approximately 71–73 kg (11st 2lbs to 11st 6lbs). However, your ideal body weight depends on your individual health, muscle mass, and fitness level rather than just averages. According to NHS guidelines, a healthy weight range for your height falls between specific BMI thresholds. This guide explains what healthy weight means for 5'9 females and how to use BMI as a health context tool.

What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is the most widely used screening tool for assessing whether your weight falls within a healthy range. Used by the NHS, GPs, and weight management services across the UK, BMI provides a quick snapshot of your weight relative to your height. The formula is simple: your weight in kilograms divided by your height in metres squared (kg/m²).
While BMI isn't a perfect measure — it doesn't account for muscle mass, bone density, or fat distribution — it remains the standard first step in identifying potential weight-related health risks including type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers.
The NHS also recommends adjusted thresholds for people of South Asian, Chinese, or Black African heritage — a BMI of 23 or above is classified as overweight, and 27.5 as obese. Our calculator includes this adjustment as a one-click toggle.
Healthy Weight Range For 5'9 Female — BMI-Based Guide
For a 5'9 female, the healthy weight range based on NHS BMI guidelines (BMI 18.5–24.9) is approximately 55–71 kg (8st 10lbs to 11st 2lbs). This range accounts for natural variation in frame size, muscle mass, and bone density.
To calculate this: a healthy BMI of 18.5 multiplied by your height (1.75m) squared equals 55 kg as the lower bound. A BMI of 24.9 at the same height equals 71 kg as the upper bound.
The average weight for 5'9 females in the UK sits comfortably within this healthy range. However, BMI has limitations — it doesn't distinguish between muscle and fat, so an athlete or very muscular woman at the higher end of this range may still be in excellent health. Our free BMI calculator above can help you determine exactly where your weight sits on the BMI scale and what category applies to you personally.
If you're of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends a slightly lower healthy weight range (BMI 18.5–22.9), which would be approximately 55–65 kg for your height.

How To Check Your Personal Healthy Weight Using The BMI Calculator
Your ideal weight range isn't just about averages — it's personal to you. The best way to determine what healthy weight means for you is to calculate your BMI using your actual weight and height. Use our free BMI calculator on this page: enter your weight in kg or stone and your height in cm or feet, and you'll instantly see your BMI category according to NHS guidelines.
If your weight falls in the overweight or obese range, even a modest weight loss of 5–10% can bring meaningful health benefits. Use our free weight converter to switch between kg, stone, and pounds as needed, then track your progress with our free progress tracker as you work towards your personalised healthy weight goal. Your GP can also provide tailored advice about what healthy weight means specifically for your health and circumstances.

The average weight for a UK adult woman who is 5'9 (175cm) tall is approximately 71–73 kg (11st 2lbs to 11st 6lbs). However, average does not mean healthy — healthy weight depends on individual factors like muscle mass, fitness, and overall health, not just population averages.
What is the healthy weight range for someone 5'9?
According to NHS BMI guidelines, a healthy weight range for a 5'9 female is approximately 55–71 kg (8st 10lbs to 11st 2lbs), corresponding to a BMI of 18.5–24.9. This accounts for natural variation in frame size and muscle mass. Use our BMI calculator above to find your personal BMI.

What's the difference between average weight and healthy weight?
Average weight is what most people of a given height weigh — a population statistic.
