Women's Height and Weight Chart — UK Health Guide
A women's height and weight chart helps you understand what a healthy weight range looks like for your height. This UK guide shows healthy weight ranges for adult women using NHS BMI guidelines, with measurements in stone, kilograms, and pounds. Whether you're checking your current weight or planning health management, understanding where you fall on a weight chart gives you clear context. Use our free BMI calculator and weight converter to find your personal healthy weight range and convert between UK measurements instantly.

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 Ranges for Women by Height (UK NHS Guidelines)
The NHS defines a healthy weight as a BMI between 18.5 and 24.9 for most adult women. For women of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends a slightly lower range of 18.5 to 22.9 due to higher health risks at lower BMI levels. Here's how healthy weight ranges work by height:
- 160cm (5ft 3in): Healthy weight is approximately 47–63kg (7st 4lbs–9st 13lbs)
- 165cm (5ft 5in): Healthy weight is approximately 50–68kg (7st 12lbs–10st 10lbs)
- 168cm (5ft 6in): Healthy weight is approximately 52–71kg (8st 3lbs–11st 2lbs)
- 170cm (5ft 7in): Healthy weight is approximately 53–74kg (8st 5lbs–11st 9lbs)
- 173cm (5ft 8in): Healthy weight is approximately 55–77kg (8st 9lbs–12st 1lb)
- 175cm (5ft 9in): Healthy weight is approximately 57–80kg (8st 13lbs–12st 8lbs)
- 180cm (5ft 11in): Healthy weight is approximately 60–85kg (9st 6lbs–13st 5lbs)
These ranges are based on NHS BMI thresholds and account for individual variation in frame size and muscle mass.

What If Your Weight Falls Outside These Ranges?
If your weight falls above or below the healthy range for your height, speaking with your GP is a sensible next step. Your GP can assess your individual health context, which includes factors beyond weight like fitness, blood pressure, and family health history. If you're overweight and interested in weight management support, NHS health advice recommends starting with lifestyle changes—reduced-calorie diet and increased physical activity. For some women, prescription weight management medications may be appropriate following clinical assessment. Remember that healthy weight is individual, and the chart is a guide, not a definitive target for everyone.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
How accurate is a height and weight chart for women?
Height and weight charts are useful screening tools based on NHS BMI guidelines, but they have limitations. They don't account for muscle mass, bone density, or where fat is stored on your body. Two women of identical height and weight may have different body compositions. Use the chart as a starting point, not a definitive measure of health.
Why do NHS recommendations differ for women of different ethnic backgrounds?
Research shows that women of South Asian, Chinese, Black African, and Black Caribbean heritage have a higher risk of type 2 diabetes and cardiovascular disease at lower BMI levels. The NHS recommends slightly lower healthy weight thresholds (18.5–22.9) for these groups to better reflect their individual health risk profiles.
Can I use a women's weight chart to set a weight loss goal?
Yes, a weight chart can help you identify a healthy target weight range for your height. However, sustainable weight loss works best when guided by a healthcare professional. Your GP can help you set realistic targets based on your current health, lifestyle, and any medical conditions you may have.
What should I do if I'm struggling to stay within the healthy weight range?
Start by speaking with your GP, who can assess your individual situation and discuss lifestyle support options including dietary advice and physical activity programmes. The NHS offers free weight management support through its Health and Care Services. For some women, prescription weight management treatment may be considered following clinical assessment.
How does waist measurement fit into women's weight charts?
While height and weight charts focus on BMI, the NHS also recommends checking waist circumference. For women, a waist measurement above 80cm (31.5 inches) indicates increased health risk, and above 88cm (34.5 inches) indicates high risk—regardless of BMI. Combined with weight, waist measurement gives a fuller picture of health risk.
