Weight Height Female Chart — UK Health Guide
A weight height female chart helps you understand what constitutes a healthy weight range for your height according to UK health standards. The NHS provides guidance on healthy weight ranges for women based on height, using BMI (body mass index) as a screening tool. Your individual healthy weight depends on several factors including age, muscle mass, bone density, and overall health. This guide shows you how to interpret UK weight and height data, use our free BMI calculator to check your personal range, and understand when to speak with your GP about weight management.

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 Ranges for Women by Height
The NHS defines a healthy BMI range as 18.5 to 24.9 for most UK adults. This translates to different weight ranges depending on your height. For women of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends a lower healthy BMI range of 18.5 to 22.9, as research shows these groups face higher health risks at lower BMI levels.
- At 5ft 2in (157cm): Healthy weight range is approximately 47–62kg (7st 5lbs to 9st 10lbs)
- At 5ft 4in (163cm): Healthy weight range is approximately 49–66kg (7st 10lbs to 10st 5lbs)
- At 5ft 6in (168cm): Healthy weight range is approximately 52–70kg (8st 3lbs to 11st 0lbs)
- At 5ft 8in (173cm): Healthy weight range is approximately 55–74kg (8st 8lbs to 11st 9lbs)
Remember that BMI is a useful screening tool but has limitations — it does not account for muscle mass, bone density, or where fat is stored. Use our free BMI calculator above to find your personal BMI and healthy weight range based on your exact height.

Why Weight and Height Matter for Health
Your weight in relation to your height is one indicator of whether you're at increased health risk. Being consistently overweight or obese can increase your risk of type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers. However, weight is only one part of the health picture — waist circumference, fitness level, and overall lifestyle also matter significantly.
The NHS recommends a safe weight loss of 0.5–1kg (1–2lbs) per week if you're working to reach a healthier weight. If you're concerned about your weight or health, your GP can provide personalised advice and, if appropriate, refer you to weight management services. Try our weight converter to understand your weight in different measurements, and use the free weight management resources available through your GP or NHS services.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is the healthy weight range for a woman who is 5ft 5in tall?
For a woman who is 5ft 5in (165cm) tall, the NHS healthy weight range is approximately 50–68kg (7st 12lbs to 10st 10lbs), based on a BMI of 18.5 to 24.9. Your exact healthy weight depends on factors like muscle mass and bone structure. Use our BMI calculator to check your personal range and speak with your GP for personalised advice.
Does a weight height chart apply equally to all women?
BMI charts apply differently depending on ethnicity. For women of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends lower BMI thresholds (18.5 to 22.9) because these groups have higher health risks at lower weights. Age, fitness level, and medical history also affect what's healthy for you individually.
How do I convert my weight to understand where I fall on a female weight chart?
Use our free weight converter to switch between kg, stone, and pounds. Once you know your weight in the same unit as the chart, compare it to your height range. Our BMI calculator also instantly shows where your weight falls on the healthy weight spectrum for your exact height and gives you the corresponding BMI.
What should I do if my weight is outside the healthy range shown on the chart?
If your weight is outside the NHS healthy range for your height, speak with your GP. They can assess your individual health, consider other factors like fitness and medical history, and discuss whether weight management is right for you. The NHS offers free weight loss support through tier 1 and tier 2 services in most areas.
Is BMI the only measure of whether a woman is a healthy weight?
No. While BMI is a useful screening tool, it doesn't account for muscle mass, bone density, or where fat is stored. The NHS also recommends checking waist circumference — for women, a waist over 80cm (31.5in) indicates increased health risk. Your GP can give you a full health assessment beyond just weight and height.
