What Is The Ideal Weight For A 5'2" Female?
The ideal weight for a 5'2" (157cm) woman is typically between 47–64 kg (7 stone 5lbs to 10 stone 1lb), based on NHS healthy BMI guidelines. However, "ideal" weight varies significantly depending on factors like muscle mass, frame size, age, and ethnicity. Rather than a single number, the NHS recommends aiming for a healthy weight range based on your BMI of 18.5 to 24.9. Use our free BMI calculator above to find your personal healthy weight range instantly.

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 5'2" Women — NHS Data
According to NHS guidelines, the healthy BMI range is 18.5 to 24.9 for most adults. For a woman who is 5'2" (157cm) tall, this translates to a healthy weight range of approximately 47–64 kg (7 stone 5lbs to 10 stone 1lb).
Using our free weight converter, you can easily switch between kilograms and stone. The calculation uses the formula: healthy weight = BMI × height² (in metres). The lower end of this range (BMI 18.5) represents a healthy minimum weight, whilst the upper end (BMI 24.9) represents the threshold before the overweight category begins.
- Lower healthy limit: 47 kg (7 stone 5lbs) — BMI 18.5
- Upper healthy limit: 64 kg (10 stone 1lb) — BMI 24.9
- Midpoint (average healthy weight): 55–56 kg (8 stone 8–9lbs)
These figures follow NHS and NICE guidance for adult weight assessment. However, BMI is a screening tool only — it does not account for muscle mass, bone density, or where fat is stored on your body.

Factors That Affect Your Ideal Weight
There is no single "perfect" weight because your ideal body weight depends on many individual factors beyond height alone. Muscle weighs more than fat, so two women of the same height and BMI may look very different. Frame size also matters — women with larger bone structures naturally weigh more at the same height.
Other key factors include:
- Age: Metabolism naturally slows with age; older women may have higher healthy weight ranges
- Ethnicity: The NHS recommends lower BMI thresholds (18.5–22.9) for South Asian, Chinese, Black African, and Black Caribbean women due to higher disease risk at the same weight
- Medical history: Conditions affecting metabolism or requiring certain medications influence what is healthy for you personally
- Fitness level: Athletes and very active women may legitimately have higher weights due to muscle mass
Your GP can provide personalised advice about your healthy weight range based on your individual health profile.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is the average weight for a 5'2" woman in the UK?
UK Office for National Statistics data shows the average adult woman weighs approximately 71.6 kg (11 stone 3lbs). However, average weight and healthy weight are different. A 5'2" woman with a healthy BMI would typically weigh 47–64 kg. The average may be higher due to the prevalence of overweight in the population.
Is 60 kg a good weight for a 5'2" female?
At 60 kg, a 5'2" woman would have a BMI of approximately 24.4, which falls comfortably within the healthy BMI range of 18.5–24.9 according to NHS guidelines. This is a healthy weight. However, consult your GP if you have concerns about your personal health, as ideal weight varies based on muscle mass, frame size, and medical history.
Can I use the BMI calculator to check if my weight is healthy?
Yes. Our free BMI calculator on this page instantly calculates your BMI based on your height and weight. Enter your measurements in stone/lbs or kg, and it will show you where your BMI falls and whether it's in the healthy, overweight, or obese range according to NHS guidelines. Remember that BMI is a screening tool and doesn't account for muscle or frame size.
Are the healthy weight ranges different for South Asian or Black women?
Yes. The NHS recommends lower BMI thresholds for women of South Asian, Chinese, Black African, and Black Caribbean heritage because these groups face higher health risks (type 2 diabetes, heart disease) at lower BMI levels. For these groups, the healthy BMI range is 18.5–22.9 rather than 18.5–24.9. Speak with your GP about the most appropriate healthy weight range for you.
What's the difference between ideal weight and healthy weight?
Healthy weight refers to a range based on BMI and health markers like blood pressure and cholesterol. Ideal weight is more personal and depends on your individual circumstances — muscle mass, frame size, age, fitness, and medical history. The healthy weight range gives you a science-based target; your ideal weight within that range is unique to you. Use our weight loss calculator to explore realistic targets.
