Healthy Weight for a 5ft 5in Female
If you're 5ft 5in (165cm) tall, a healthy weight according to NHS guidelines falls within a specific BMI range that translates to approximately 50–67 kg (7st 12lbs to 10st 7lbs). However, the ideal weight for your individual body depends on several factors including muscle mass, bone density, and overall fitness. Using our free BMI calculator, you can discover your personal healthy weight range and understand what that means for your health. This guide explains the NHS framework for healthy weight at your height and how to find the right target for you.

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 5ft 5in Females — BMI Based
For a female who is 5ft 5in tall, the NHS healthy BMI range is 18.5 to 24.9. This translates to a healthy weight of approximately 50–67 kg (7st 12lbs to 10st 7lbs). At the lower end of this range (BMI 18.5), you would weigh around 50 kg (7st 12lbs); at the upper end (BMI 24.9), around 67 kg (10st 7lbs). These figures represent a healthy weight range for your height, but the right weight for you specifically depends on your individual body composition, muscle mass, and overall health. The average UK woman of similar height weighs approximately 72 kg (11st 3lbs), which falls slightly into the overweight category by BMI standards, though BMI is just one health indicator. Use our weight converter above to switch between kilograms, stone, and pounds to see exactly what these figures mean in your preferred units.

Using the BMI Calculator to Find Your Healthy Weight Target
The most practical way to discover your personal healthy weight range is to use our free BMI calculator. Simply enter your height (5ft 5in) and current weight, and the calculator will show you exactly where you fall on the NHS BMI scale and what your healthy weight range should be. A BMI between 18.5 and 24.9 is considered healthy, while 25–29.9 is overweight, and 30 or above is obese by NHS classification. If you're working towards a healthier weight, tracking your progress with our free progress tracker can help you stay motivated and see gradual improvements over time. Remember that sustainable weight loss happens at approximately 0.5–1 kg per week, and even modest weight loss of 5–10% of your body weight can improve your health significantly.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is the healthy weight range for a 5ft 5in female in stone?
According to NHS BMI guidelines, a healthy weight for a 5ft 5in female is approximately 7st 12lbs to 10st 7lbs (50–67 kg). This corresponds to a BMI of 18.5 to 24.9. The exact healthy weight for you depends on your muscle mass and overall body composition, so it's best to use our BMI calculator to find your personal range.
Is 72 kg overweight for a 5ft 5in female?
At 72 kg, a 5ft 5in female would have a BMI of approximately 28.6, which falls into the overweight category according to NHS guidelines (25–29.9). The healthy weight range for this height is 50–67 kg. However, BMI does not account for muscle mass, so an athletic person at this weight may have a healthy body composition. Your GP can offer personalised health advice.
How do I calculate my BMI if I'm 5ft 5in?
To calculate your BMI, divide your weight in kilograms by your height in metres squared. For someone 5ft 5in (1.65m) tall: BMI = weight (kg) ÷ (1.65)². Alternatively, use our free BMI calculator above to get an gradual improvement with your health category and healthy weight range.
What's the difference between healthy weight and ideal weight?
Healthy weight is defined by the NHS BMI range (18.5–24.9) for your height. Ideal weight is more individual and depends on your body composition, muscle mass, fitness level, and personal health goals. A healthy weight is realistic for most people; ideal weight may be more subjective. Your GP can help determine what's right for you.
Should I aim for the lower or upper end of the healthy weight range?
Both the lower end (approximately 50 kg / 7st 12lbs) and upper end (approximately 67 kg / 10st 7lbs) of the healthy BMI range are equally valid. The right weight for you depends on your frame size, muscle mass, and fitness. A healthcare professional can help you set a realistic, personalised goal based on your individual circumstances.
