Average Weight for a 5ft 2in Woman — UK Context
The average UK woman aged 16 and over weighs approximately 71.6 kg (11 stone 3 lbs), but weight varies significantly based on individual factors including age, muscle mass, and lifestyle. For a woman who is 5ft 2in (157cm) tall, the NHS healthy weight range is typically between 47 kg and 64 kg (7 stone 5 lbs to 10 stone 1 lb), based on a BMI of 18.5 to 24.9. Understanding your ideal weight range is more useful than comparing yourself to national averages, as health depends on your personal BMI and overall fitness rather than matching someone else's weight.

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 2in — BMI Framework
A woman who is 5ft 2in (157cm) tall falls into a specific healthy weight range according to NHS BMI guidelines. The healthy BMI range is 18.5 to 24.9, which translates to a weight range of approximately 47–64 kg (7 stone 5 lbs to 10 stone 1 lb) for this height.
- Lower end (BMI 18.5): 47 kg or 7 stone 5 lbs — considered underweight if approached from below
- Mid-range (BMI 21–22): 52–55 kg or 8 stone 3–8 stone 10 lbs — typically considered the ideal healthy weight
- Upper end (BMI 24.9): 64 kg or 10 stone 1 lb — top of the healthy range
If a woman of this height weighs 65 kg (10 stone 3 lbs) or above, her BMI enters the overweight category (25.0–29.9). At 80 kg (12 stone 8 lbs), the BMI reaches the obese category (30.0+).

Using the BMI Calculator for Your Personal Range
Rather than aiming for the average UK weight, it's more helpful to find your healthy weight range based on your own height and health goals. Everyone's body is different — genetics, muscle mass, bone density, and fitness level all influence what a healthy weight looks like for you personally. Our free BMI calculator on this page takes your height and weight and instantly shows you your BMI category according to NHS guidelines. If you're concerned about your weight or have weight-related health conditions like high blood pressure or type 2 diabetes, your GP can give you personalised guidance on the best weight range for your individual circumstances.
