Healthy Weight For A 5 Foot Woman
For a woman who is 5 feet tall (152.4 cm), the NHS healthy weight range is approximately 47–64 kg (7 stone 5 lbs to 10 stone 1 lb). This range is based on a healthy BMI of 18.5 to 24.9. However, your ideal body weight depends on individual factors including muscle mass, frame size, age, and ethnicity. Use our free BMI calculator above to check your personal healthy weight range instantly, or explore the information below to understand what healthy weight means for your height and individual 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.
NHS Healthy Weight Range For 5 Foot Women
According to NHS guidelines, the healthy BMI range is 18.5 to 24.9 for most adults. For a woman 5 feet (152.4 cm) tall, this translates to:
- Lower healthy weight: 47 kg (7 stone 5 lbs)
- Upper healthy weight: 64 kg (10 stone 1 lb)
- Healthy weight range: 47–64 kg (7st 5lbs to 10st 1lb)
The average UK woman is taller than 5 feet, but women at this height fall within normal weight ranges across the UK population. However, if you're of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends lower BMI thresholds: aim for a BMI of 18.5 to 22.9, which gives a healthy weight range of approximately 47–56 kg (7st 5lbs to 8st 12lbs) for your height.

Factors Affecting Your Ideal Weight
Your ideal healthy weight isn't one fixed number — it varies based on several important factors. Muscle mass weighs more than fat, so two women of the same height and BMI can look and feel very different depending on fitness level. Frame size matters too: smaller-framed women naturally weigh less than larger-framed women at the same height. Age affects metabolism and muscle loss, so your ideal weight may shift over time. Ethnicity also influences healthy weight thresholds, as the NHS recognises that certain populations face higher health risks at lower BMI levels. Rather than targeting a single number, focus on achieving a healthy BMI for your height and how you feel physically. Your GP can provide personalised guidance on what healthy weight means for you.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is the exact healthy weight for a 5 foot woman?
The NHS healthy weight range for a 5 foot woman is 47–64 kg (7 stone 5 lbs to 10 stone 1 lb), based on a healthy BMI of 18.5–24.9. However, within this range, your ideal weight depends on muscle mass, frame size, and individual health factors. For adults of South Asian or Black African heritage, lower thresholds apply: 47–56 kg (7st 5lbs to 8st 12lbs).
Is there an average weight for a 5 foot woman in the UK?
The average UK woman is approximately 5 feet 3 inches tall and weighs around 71.6 kg (11 stone 3 lbs). Since 5 feet is shorter than average, women at this height typically weigh less — usually in the lower-to-middle range of the healthy weight bracket for their height. Individual variation is significant.
How do I know if my weight is healthy?
Use our free BMI calculator above to check your personal BMI. A BMI of 18.5–24.9 is considered healthy by the NHS. You should also consider how you feel physically, your energy levels, and any weight-related health conditions. Your GP can give you personalised advice about your individual healthy weight.
Does muscle mass affect my ideal weight?
Yes, significantly. Muscle weighs more than fat, so a fit woman at your height might weigh more than an sedentary woman at the same height yet have a healthier body composition. BMI doesn't distinguish between muscle and fat, which is one of its limitations. Consider your overall fitness and health, not just the number on the scales.
Are healthy weight ranges different for different ethnicities?
Yes. The NHS recommends lower BMI thresholds for people of South Asian, Chinese, Black African, and Black Caribbean heritage because these groups face higher risks of type 2 diabetes and heart disease at lower BMI levels. For a 5 foot woman from these backgrounds, the healthy range is typically 47–56 kg rather than 47–64 kg.
