Ideal Weight for a 5ft Female — UK Health Reference
For a woman who is 5ft tall (152cm), the healthy weight range according to NHS guidelines is approximately 44–59kg (97–130 lbs or 6st 13lbs–9st 4lbs). However, ideal weight varies significantly based on muscle mass, frame size, age, and ethnicity. This guide explains the data behind healthy weight for women at this height, and how to find your personal ideal weight range using evidence-based health markers.

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 Females — NHS Data
For a woman measuring 5ft (152cm), the NHS healthy weight range is 44–59kg. This is calculated using the BMI formula for a healthy BMI of 18.5–24.9, which is the standard across UK health services.
- Lower healthy weight: 44kg (6st 13lbs or 97 lbs)
- Upper healthy weight: 59kg (9st 4lbs or 130 lbs)
Use our free BMI calculator above to check your personal BMI and see where you fall within this range. However, BMI is a screening tool only — it doesn't account for muscle mass, bone density, or where fat is stored on your body. For women of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends a slightly lower healthy weight range of 44–53kg, as these groups face higher cardiovascular risk at standard BMI thresholds.

Factors Affecting Your Ideal Body Weight
Ideal weight isn't one-size-fits-all. Several factors influence what's healthy for you personally:
- Muscle mass: Athletes and active women may weigh more but have lower body fat percentage
- Frame size: Women with larger bone structure naturally weigh more than those with smaller frames
- Age: Metabolic rate changes with age; women over 50 often need fewer calories
- Ethnicity: Risk thresholds vary; South Asian women face higher diabetes risk at lower BMI
- Health conditions: Thyroid disorders, PCOS, and medications affect weight management
Your GP can give you personalised advice on what healthy weight looks like for your individual body. Try our free weight converter to see how different weights in kg, stone, and pounds compare.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What's the average weight for a 5ft female in the UK?
According to UK Office for National Statistics data, the average UK adult woman weighs approximately 71.6kg (11st 3lbs). However, average weight is higher than healthy weight — many women above this figure can still be in a healthy BMI range. Your ideal weight depends on your personal health markers, not the population average.
Is there a difference between "ideal weight" and "healthy weight"?
Yes. Healthy weight is defined by BMI range (18.5–24.9 for most women). Ideal weight is more personal — it accounts for your muscle mass, frame size, and individual health goals. A woman with significant muscle may be at the higher end of or even above the healthy range but still be very fit.
How do I calculate my ideal weight range?
Use the formula: healthy weight = BMI × height(m)². For 5ft (1.52m), multiply 18.5 and 24.9 by 2.31 to get 44–59kg. Our free BMI calculator above does this instantly. Remember that this is a guide, not a target — your GP can advise what's right for you specifically.
Does my ethnicity affect what's an ideal weight?
Yes. The NHS recognises that South Asian, Chinese, Black African, and Black Caribbean adults have higher health risks at lower BMI levels. If you're from these backgrounds, a GP may recommend aiming for the lower end of the healthy range (BMI 18.5–22.9) rather than the standard range.
Should I aim for the lower or upper end of the healthy weight range?
Neither is "ideal" — it depends on you. Women with more muscle naturally sit higher; those with smaller frames may sit lower. The key is being within the range and feeling healthy. If you're struggling with weight management, our free GLP-1 weight loss calculator can help project outcomes with medical support, or your GP can advise on personalised approaches.
