Female Height vs Weight Chart — UK Health Guidance
A female height vs weight chart shows the healthy weight range for women at different heights according to NHS guidelines. In the UK, we use stone and pounds or kilograms to measure weight, and centimetres or feet and inches for height. Your healthy weight depends on your height, age, muscle mass, and individual health factors — not just a number on a scale. This guide explains how to use a height and weight chart, what healthy weight means in UK context, and how to assess your personal health using evidence-based NHS guidance.

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.
Understanding Healthy Weight Ranges for Women in the UK
The NHS defines a healthy weight using BMI (Body Mass Index), which compares your weight to your height. For most UK women, a healthy BMI falls between 18.5 and 24.9. This means the healthy weight range varies significantly by height.
For example, a woman who is 5ft 4in (163cm) tall has a healthy weight range of approximately 50–65kg (7st 12lbs to 10st 3lbs). A woman who is 5ft 8in (173cm) tall has a healthy weight range of approximately 55–75kg (8st 9lbs to 11st 11lbs). Use our free BMI calculator above to find your personal healthy weight range instantly based on your exact height and weight.
Important: These ranges are guidelines, not targets. Your GP may discuss a different healthy weight based on your muscle mass, fitness level, age, and any health conditions you have. Women of South Asian, Chinese, Black African, or Black Caribbean heritage have lower recommended BMI thresholds (18.5–22.9) because these groups face higher health risks at the same BMI as other populations.

Using a Height vs Weight Chart for Women — What It Tells You
A height vs weight chart is a simple screening tool, but it has important limitations. BMI does not distinguish between muscle and fat — so a woman with high muscle mass may have a higher BMI than a chart suggests is "healthy" without any health concern. The chart also does not account for where fat is stored on your body, which matters for health risk.
For a more complete picture of your health: discuss your weight and health history with your GP, who can assess your individual risk factors for type 2 diabetes, heart disease, and other conditions. Your GP can also measure your waist circumference — for women, a healthy waist measurement is under 80cm (31.5 inches). Use our free weight converter to switch between kg, stone, and pounds if you want to compare your weight to a chart using different units.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is a healthy weight for a 5ft 6in woman in the UK?
A woman who is 5ft 6in (168cm) tall has a healthy weight range of approximately 53–71kg (8st 5lbs to 11st 2lbs) according to NHS BMI guidelines. However, your individual healthy weight depends on your age, muscle mass, fitness level, and any health conditions. Discuss your personal target weight with your GP.
How do I use a female height and weight chart?
Find your height on the left side of the chart and your weight on the bottom. Where they meet shows your BMI category — healthy weight (18.5–24.9), overweight (25–29.9), or obese (30+). Use our free BMI calculator above for a precise calculation based on your exact height and weight measurements.
Do height and weight charts apply to all women equally?
Not exactly. Women of South Asian, Chinese, Black African, or Black Caribbean heritage have lower recommended BMI thresholds (18.5–22.9 instead of 18.5–24.9) according to NHS guidance, because these groups face higher health risks at the same BMI levels. Your GP can advise on what's healthy for you specifically.
Is a height and weight chart the only way to assess health?
No. BMI and height-weight charts are useful screening tools but don't account for muscle mass, fat distribution, or overall fitness. The best approach combines a chart assessment with GP advice, waist circumference measurement, fitness level, and discussion of your individual risk factors for weight-related health conditions.
What should I do if my weight is outside the healthy range for my height?
If your weight is outside the healthy range, discuss this with your GP. They can assess your overall health, identify any underlying conditions affecting your weight, and talk through weight management options including lifestyle changes, weight management programmes, and where relevant, prescription medication options.
