What's a Normal Weight for a 5'4" Female?
For a woman who is 5'4" (163cm), the NHS healthy weight range is approximately 50 to 67kg, which converts to between 7 stone 12 pounds and 10 stone 7 pounds in UK measurements. This range corresponds to a BMI of 18.5 to 24.9, the healthy weight band according to NHS guidelines. However, your ideal weight within this range depends on factors including muscle mass, frame size, and overall health. Calculate your personal BMI instantly using our free BMI calculator above to see where you fall within the healthy range for your height.

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 5'4" Females
According to NHS guidelines, the ideal weight for a 5'4" female falls between 50kg and 67kg (7st 12lbs to 10st 7lbs). This range is based on a healthy BMI of 18.5 to 24.9, which is the standard used across UK health services.
- Lower bound (BMI 18.5): approximately 50kg (7st 12lbs)
- Upper bound (BMI 24.9): approximately 67kg (10st 7lbs)
- Midpoint (BMI 21.7): approximately 58–59kg (9st 3lbs–9st 4lbs)
Your healthy weight calculator can help you find the right target for your individual circumstances. If you're of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends slightly lower thresholds — your healthy weight range would be approximately 50–63kg (7st 12lbs–9st 13lbs), as these populations face higher health risks at standard BMI levels.

What Affects Your Ideal Weight?
Your ideal weight within the healthy range depends on several personal factors beyond height alone. Muscle mass significantly impacts weight — someone who is fit and active may weigh more than average weight figures suggest, as muscle is denser than fat. Frame size also matters: women with a larger or smaller frame may naturally fall at different points within the healthy range. Age can affect metabolism and body composition, whilst genetics play a role in how your body distributes weight. Use our free weight converter to explore different weights in both kg and stone, then consult your GP if you're unsure whether a particular weight is healthy for you personally.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What's the average UK weight for a 5'4" female?
The average UK adult woman weighs approximately 71.6kg (11st 3lbs), though this is higher than the healthy range. Average weight varies by age group and region. Your personal healthy weight depends more on your health markers (BMI, blood pressure, fitness) than on average figures. Aim for the NHS healthy range rather than matching national averages.
How do I know my ideal weight within the 50–67kg range?
Your ideal weight depends on muscle mass, frame size, and genetics. A good starting point is the midpoint of your healthy range (around 58–59kg for 5'4"), then adjust based on how you feel, your energy levels, and your health markers. Your GP or a registered dietitian can give personalised guidance based on your individual circumstances and health history.
Is 60kg a healthy weight for a 5'4" female?
Yes, 60kg (9st 6lbs) falls comfortably within the healthy weight range for a 5'4" female, giving a BMI of approximately 22.3, which is in the middle of the healthy band. This is a reasonable target weight for most women of this height, though your ideal weight may differ based on muscle mass and frame size.
Does my ethnicity affect what's a healthy weight for my height?
Yes. The NHS recommends lower BMI thresholds for South Asian, Chinese, Black African, and Black Caribbean adults because these populations have higher health risks at standard BMI levels. If you're from one of these backgrounds, your healthy weight range for 5'4" would be approximately 50–63kg (7st 12lbs–9st 13lbs) rather than the standard 50–67kg range.
Should I aim for the bottom or top of the healthy weight range?
Neither is "better" — both are healthy. Your ideal target depends on your personal circumstances: muscle mass, frame size, how you feel, and your health markers. Many people find the middle of their range (around 58–59kg for 5'4") is sustainable and supports good health. Work with your GP if you're trying to reach a specific target weight.
