What's the Ideal Weight for a Woman 5'2"?
For a woman who is 5'2" (157.5 cm), the ideal healthy weight range according to NHS guidelines is approximately 47–63 kg (7 stone 5 lbs to 9 stone 13 lbs). This range is based on a healthy BMI of 18.5 to 24.9, which applies to most UK adults. However, "ideal" weight varies depending on factors like muscle mass, frame size, and ethnicity. Use our free BMI calculator above to check your personal BMI and healthy weight range instantly based on your individual measurements and circumstances.

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 — By the Numbers
The healthy weight range for a 5'2" woman according to NHS guidelines is 47–63 kg, which converts to 7 stone 5 lbs to 9 stone 13 lbs in UK measurements. This is calculated using the NHS healthy weight BMI range of 18.5 to 24.9 for most adults. At the lower end (BMI 18.5), your weight would be around 47 kg. At the upper end (BMI 24.9), approximately 63 kg.
For women of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends a slightly lower healthy weight range due to higher health risks at the same BMI. In those cases, a BMI of 18.5 to 22.9 is recommended, which translates to approximately 47–57 kg (7 stone 5 lbs to 8 stone 13 lbs).
The average UK woman weighs approximately 71.6 kg (11 stone 3 lbs), which means many are above the healthy weight range. Our weight converter can help you switch between kg, stone, and lbs to understand your own weight in different units.

Factors That Affect Your Ideal Weight
Ideal body weight isn't one-size-fits-all. Several factors influence what's healthy for you specifically:
- Muscle mass: Muscle is denser than fat, so athletic women may weigh more than sedentary women at the same height while remaining healthy. BMI has limitations — it doesn't distinguish between muscle and fat.
- Frame size: Small-framed women may be healthy at the lower end of the range; large-framed women at the upper end.
- Age: Metabolism slows with age, and muscle naturally decreases, affecting your ideal weight.
- Ethnicity: As noted above, some ethnic groups have different health risk profiles at the same BMI.
Your GP can give personalised advice about what's healthy for you individually.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
Is 60 kg a healthy weight for a 5'2" woman?
Yes, 60 kg (9 stone 6 lbs) falls within the healthy weight range for a 5'2" woman, giving a BMI of approximately 22.5. However, individual health depends on many factors beyond weight alone. Your GP can assess your personal health in context.
What's the average weight for a UK woman who is 5'2"?
The average UK adult woman weighs around 71.6 kg (11 stone 3 lbs), though this varies significantly by height. At 5'2", many women will be above the NHS healthy weight range. Using our BMI calculator can help you see where you fall personally.
How do I calculate my healthy weight range for my height?
Multiply your height in metres by itself, then multiply by 18.5 (lower bound) and 24.9 (upper bound). For 5'2" (1.575 m): 1.575² × 18.5 = 46 kg; 1.575² × 24.9 = 62 kg. Our free healthy weight calculator does this instantly.
Does muscle mass affect what my ideal weight should be?
Yes, muscle weighs more than fat, so athletic or muscular women may be healthy at a higher weight than sedentary women of the same height. BMI is a screening tool but has limitations. Waist circumference and overall fitness matter too.
Should I aim for the lower or upper end of the healthy weight range?
There's no single "ideal" — both are healthy. Your personal ideal depends on frame size, muscle mass, age, and health conditions. Start with the healthy range as a guide, then discuss with your GP what's realistic and healthy for you specifically.
