What's the Ideal Weight for a 5'2" Female?
For a woman of 5'2" (157cm), the ideal weight range according to NHS guidelines is approximately 50–67kg, which converts to 7 stone 12 pounds to 10 stone 7 pounds in UK measurements. This healthy weight range is calculated using BMI thresholds of 18.5 to 24.9, the NHS standard for adults. However, "ideal weight" varies based on individual factors including muscle mass, bone density, frame size, age, and ethnicity. Your own ideal weight may fall within this range but be personalised to your specific health profile. Use our free BMI calculator to determine where your current weight sits on the healthy weight spectrum.

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 — The Data
The healthy weight range for a 5'2" female is 50–67kg (7st 12lbs–10st 7lbs) according to NHS BMI guidelines. This range represents a BMI of 18.5 to 24.9, which is the recommended threshold for healthy weight in UK adults.
- Lower end (BMI 18.5): 50kg / 7st 12lbs — minimum healthy weight
- Upper end (BMI 24.9): 67kg / 10st 7lbs — maximum healthy weight range
- Midpoint (BMI 21.7): approximately 58.5kg / 9st 3lbs — optimal centre of healthy range
For comparison, the average UK woman weighs approximately 71.6kg (11st 3lbs), which would put a woman of 5'2" at a BMI of around 29 — classified as overweight. However, this is population average, not ideal. Your personal ideal weight depends on your individual health, not population statistics.

Factors Affecting Your Personal Ideal Weight
Although the NHS healthy weight range for 5'2" is 50–67kg, your personal ideal weight within or near this range depends on several individual factors. Muscle mass and frame size significantly affect ideal weight — someone with a larger frame or greater muscle mass may sit towards the upper end of the healthy range and still be perfectly healthy. Age also matters: younger women typically have more muscle, whilst older women may experience natural muscle loss. Ethnicity is important too — the NHS recommends lower BMI thresholds for women of South Asian, Chinese, Black African, or Black Caribbean heritage, who face higher health risks at the same BMI. Rather than aiming for a single number, focus on achieving a weight within the healthy range that feels sustainable for your lifestyle and supports your overall health markers like blood pressure and blood sugar control. Your GP can advise on your personal ideal weight target.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is the ideal weight for a 5'2" female in stone?
The ideal healthy weight range for a 5'2" female is 7 stone 12 pounds to 10 stone 7 pounds (50–67kg). This corresponds to a BMI of 18.5–24.9 according to NHS guidelines. Your personal ideal weight within this range depends on factors like muscle mass, frame size, and age. Use our BMI calculator to find your healthy weight range.
Is 60kg a healthy weight for a 5'2" female?
Yes, 60kg (9st 6lbs) is well within the healthy weight range for a 5'2" female, corresponding to a BMI of approximately 24.3. This is near the optimal centre of the healthy range. However, individual health depends on more than weight alone — your GP can advise on whether this weight is right for your personal circumstances.
How is ideal weight calculated for different heights?
Ideal weight ranges are calculated using BMI (Body Mass Index) thresholds. For any height, a BMI of 18.5–24.9 represents the healthy range. The formula is: weight (kg) ÷ height (metres)². For a 5'2" (1.57m) female, this produces the 50–67kg range. Our BMI calculator on this page applies these formulas instantly to your own measurements.
Does muscle mass affect ideal weight?
Yes, significantly. Muscle is denser than fat, so someone with high muscle mass may weigh more than average for their height but still be very healthy. Two women of the same height and weight can have very different body compositions. BMI is a useful screening tool but doesn't distinguish between muscle and fat, so consider both your weight and how you feel physically.
Are healthy weight ranges different for different ethnicities?
Yes. The NHS recommends lower BMI thresholds for women of South Asian, Chinese, Black African, or Black Caribbean heritage. For these groups, the healthy weight range starts at BMI 18.5–22.9 rather than 18.5–24.9, because research shows higher health risks at standard BMI thresholds. Your GP can advise on appropriate targets for your ethnicity.
