What's the average weight for a 5 foot 5 female?
At 5 foot 5 inches (165cm), the healthy weight range for an adult female according to NHS guidelines is approximately 50kg to 67kg (7 stone 12lbs to 10 stone 7lbs). This corresponds to a BMI between 18.5 and 24.9, which the NHS classifies as a healthy weight. However, average UK weight for females is higher than this healthy range — around 71.6kg — so many women fall into the overweight category. Your ideal body weight depends on your individual body composition, muscle mass, and overall health, not just the number on the scales.

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 foot 5 using BMI
Using the NHS BMI framework, here's the healthy weight range for a 5 foot 5 female:
- Healthy weight (BMI 18.5–24.9): 50kg to 67kg (7st 12lbs to 10st 7lbs)
- Overweight (BMI 25–29.9): 68kg to 82kg (10st 9lbs to 12st 12lbs)
- Obese (BMI 30+): 83kg and above (13st and above)
If you're of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends lower thresholds for health risk. Your healthy weight range would be approximately 50kg to 61kg (7st 12lbs to 9st 9lbs) to account for increased cardiovascular risk at standard BMI levels. Use our free BMI calculator above to find your exact BMI based on your current weight and height — this gives you a personalised baseline for your health status.

Using the weight for height UK framework
Weight for height is a practical way to assess whether your weight falls within a healthy range for your specific height. At 5 foot 5, a healthy weight calculator based on BMI helps you understand whether you're in the healthy, overweight, or obese range. Remember that BMI doesn't account for muscle mass — athletes or very muscular individuals may have a higher BMI but lower body fat. Factors like age, bone density, and fitness level also matter. Our free weight converter can help you switch between kg and stone easily, and our BMI calculator provides your personalised result instantly so you can see exactly where you stand.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is the average UK weight for a 5ft 5 female?
The NHS average weight for adult females in the UK is approximately 71.6kg (11st 3lbs). However, this is higher than the healthy weight range for a 5ft 5 person (50–67kg). Average doesn't mean healthy — many UK adults fall into the overweight category. Your ideal weight depends on your individual health, not the national average.
How do I calculate my ideal body weight at 5 foot 5?
Use the BMI framework: a healthy BMI is 18.5–24.9. For 5ft 5, this equals 50–67kg (7st 12lbs to 10st 7lbs). Our free BMI calculator above does this instantly — just enter your weight and height to see your BMI and where you fall in the healthy range. Your GP can also discuss what's ideal for your individual circumstances.
Is 65kg a healthy weight for a 5 foot 5 female?
Yes, 65kg (10st 3lbs) at 5ft 5 gives a BMI of approximately 24, which falls comfortably in the healthy weight range (BMI 18.5–24.9). This is within the NHS healthy weight framework for your height. However, health is individual — your GP is the best person to discuss whether this weight is ideal for your personal health.
What's the difference between average weight and healthy weight?
Average weight is what most people in a population weigh; healthy weight is the range where your risk of weight-related disease is lowest. Many UK adults are overweight, so the average is higher than the healthy range. The NHS uses BMI to define healthy weight (18.5–24.9), regardless of what's average.
How can I track my progress towards a healthy weight?
Use our free progress tracker to log your weight weekly and visualise your journey over time. Combine this with our BMI calculator to monitor your BMI changes as you progress. Aim for steady, sustainable weight loss of 0.5–1kg per week. Keep a record of measurements and how you feel — not just the number on the scales.
