What Is The Average Weight For A 5'2" Female?
The average weight for a 5'2" (157 cm) female in the UK is approximately 70 kg (11 stone), based on recent adult population data. However, "average" and "healthy" are not the same thing. According to NHS guidelines, a healthy weight range for a woman of this height is between 47 kg and 63 kg (7 stone 6 lbs to 9 stone 13 lbs), based on a BMI of 18.5 to 24.9. Your ideal body weight depends on factors like muscle mass, bone density, and overall health — not just a single number. This guide explains the healthy weight range and how to use BMI as a screening tool for this height.

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" Females (BMI Context)
For a woman of 5'2" (157 cm), the healthy weight range according to NHS BMI guidelines is:
- Lower bound: 47 kg (7 stone 6 lbs) — BMI 18.5
- Upper bound: 63 kg (9 stone 13 lbs) — BMI 24.9
This range assumes average muscle and bone density. If you have a naturally muscular build, you may fall slightly above this range whilst maintaining good health. Conversely, if you have lower muscle mass, you may be healthy at the lower end.
Using the standard BMI formula (weight in kg ÷ height in metres²), a weight of 70 kg at 5'2" gives a BMI of approximately 28.7, which falls into the overweight category (BMI 25–29.9). For comparison, the UK average adult female weight is around 71.6 kg, meaning many UK women are above the healthy range. Remember, BMI is a useful screening tool but does not account for muscle mass or body composition.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What's the difference between average weight and healthy weight?
Average weight is what most people actually weigh — approximately 70 kg for a 5'2" UK female. Healthy weight is the range supported by NHS BMI guidelines (47–63 kg for this height). Many people weigh more than the healthy range, so average and healthy are not the same. Your GP can advise on what's healthy for your individual circumstances.
Is 70 kg overweight for a 5'2" female?
At 5'2" (157 cm), a weight of 70 kg gives a BMI of approximately 28.7, which falls into the overweight category according to NHS guidelines (BMI 25–29.9). To be in the healthy BMI range, a woman of this height would need to weigh between 47–63 kg (7 stone 6 lbs to 9 stone 13 lbs).
What if I'm muscular — can I weigh more than the healthy BMI range?
Yes, BMI has limitations and does not distinguish between muscle and fat. If you have significant muscle mass, you may have a higher BMI whilst being in good health. A healthcare professional can assess your body composition more accurately than BMI alone. Waist circumference (ideally under 80 cm for women) is also a useful health indicator.
How do I find my ideal weight for my height?
Use our free BMI calculator to find your personalised healthy weight range based on your height. The NHS recommends a BMI of 18.5–24.9 for most adults. For women of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends a lower range (18.5–22.9) due to higher health risks at the same BMI.
How quickly should I aim to lose weight if I'm above the healthy range?
The NHS recommends losing weight at a rate of 0.5–1 kg per week for sustainable, long-term results. This typically involves a calorie deficit of around 500 kcal per day through a combination of dietary changes and increased physical activity. Faster weight loss can lead to muscle loss. Your GP can advise on safe approaches for your individual health situation.
