Healthy Weight Range for 5'2 Females in the UK
At 5'2" (157.5 cm), the healthy weight range for an adult female in the UK is approximately 47.5 kg to 63 kg (7 stone 6 lbs to 9 stone 12 lbs), based on NHS BMI guidelines. However, "correct" weight varies based on age, muscle mass, bone density, and individual health factors. Your GP can provide personalised advice about what weight is right for you. Using our free BMI calculator and weight converter on this page will help you understand where your current weight sits within NHS health guidance.

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.
NHS Healthy Weight Guidance for 5'2 Females
The NHS defines healthy weight using the Body Mass Index (BMI), which is calculated from your height and weight. For a 5'2" female, a healthy BMI falls between 18.5 and 24.9, which corresponds to a weight range of approximately 47.5 kg to 63 kg (7 stone 6 lbs to 9 stone 12 lbs). This is based on standard NHS guidance for most adult women.
However, if you are of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends slightly lower thresholds — a healthy BMI of 18.5 to 22.9 applies, which equates to approximately 47.5 kg to 59.5 kg (7 stone 6 lbs to 9 stone 5 lbs). This is because these groups face higher health risks from obesity-related conditions at lower BMI levels.
It's important to note that BMI is a screening tool only and does not account for muscle mass, bone density, or fat distribution. Calculate your BMI now using our free BMI calculator above to see where you currently stand.

Factors That Affect Your Ideal Weight
Your "correct" weight depends on much more than height alone. Age, muscle mass, bone density, lifestyle, medical history, and genetics all play significant roles. A woman who exercises regularly and has more muscle may weigh more than the average but be perfectly healthy. Conversely, someone at the "ideal" weight with limited physical activity may face health risks.
Rather than chasing a specific number on the scale, focus on overall health markers: blood pressure, cholesterol levels, energy, and fitness. Your GP can assess your individual health and advise whether your current weight is appropriate for you. Try our free weight converter to understand your weight in different units (kg, stone, lbs), and use our BMI calculator to check your personal BMI in the context of NHS health guidance.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is the healthy weight range for a 5'2" female in the UK?
According to NHS guidelines, the healthy weight range for a 5'2" female is approximately 47.5 kg to 63 kg (7 stone 6 lbs to 9 stone 12 lbs). This corresponds to a healthy BMI of 18.5 to 24.9. However, if you are of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends aiming for 47.5 kg to 59.5 kg (18.5–22.9 BMI).
How is the healthy weight range calculated?
The healthy weight range is based on Body Mass Index (BMI), which is calculated using your height and weight. For a 5'2" female, multiply your height in metres squared by 18.5 and 24.9 to find the weight range in kilograms. You can instantly calculate your personal BMI using our free BMI calculator on this page.
Does everyone at 5'2" have the same ideal weight?
No. Ideal weight varies significantly based on muscle mass, bone density, age, and genetics. Someone with more muscle may weigh more than the NHS range but be very healthy. Your GP can provide personalised advice about what weight is appropriate for your individual circumstances and health history.
Why are there different healthy weight ranges for different ethnic backgrounds?
The NHS recommends lower BMI thresholds for South Asian, Chinese, Black African, and Black Caribbean adults because research shows these groups have a higher risk of type 2 diabetes and cardiovascular disease at the same BMI levels as other populations. This means a lower weight threshold may be healthier for these groups.
How can I find out what I should weigh?
Use our free BMI calculator to determine your current BMI, then speak with your GP who can assess your individual health, fitness level, muscle mass, and medical history to provide personalised weight management guidance. Your GP may refer you to NHS weight management services if appropriate.
