Average Weight For A Woman 5'6" — Healthy Weight Range
The healthy weight range for a woman who is 5'6" (168cm) is approximately 53 to 68kg, or 8 stone 5 pounds to 10 stone 10 pounds in UK measurements. This range is based on an NHS-recommended BMI of 18.5 to 24.9, which is considered a healthy weight for most adults. However, the ideal body weight for any individual depends on factors like muscle mass, frame size, and overall health. Using our free BMI calculator above, you can check where your personal weight falls within the healthy range and get individualised context 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 5'6" Women — BMI Breakdown
For a woman who is 5'6" (168cm tall), the healthy BMI range of 18.5 to 24.9 translates to a weight between 53kg and 68kg. In stone and pounds, this equals 8 stone 5 pounds to 10 stone 10 pounds. The lower end of this range (BMI 18.5) represents a healthy minimum, while the upper end (BMI 24.9) is the highest weight still considered healthy by NHS guidelines.
The average UK weight for women is approximately 71.6kg (11 stone 3 pounds), which falls slightly into the overweight category. However, average does not mean ideal — many women at this height fall comfortably within or below the healthy weight range. Your ideal weight depends on your individual body composition, bone density, and muscle mass, not just the number on the scales.
- BMI 18.5: Approximately 53kg (8st 5lb)
- BMI 22 (mid-range): Approximately 61kg (9st 8lb)
- BMI 24.9: Approximately 68kg (10st 10lb)

How To Check Your Healthy Weight — Use The BMI Calculator
The most practical way to establish your personalised healthy weight range is to use our free BMI calculator on this page. Enter your height (5'6"), your current weight in kilograms or stone and pounds, and the calculator will immediately show you your BMI category and how it compares to the NHS healthy weight range. Remember that BMI is a useful screening tool, but it does not account for muscle mass or where body fat is distributed. If you have concerns about your weight or health, your GP can provide guidance tailored to your circumstances.
If you are working towards weight loss, use our free progress tracker to log changes over time. This helps you identify trends and stay motivated, rather than focusing on week-to-week fluctuations.
