What Is the Average Weight for a 5'6" Female?
At 5'6" (168 cm), the average UK adult female weighs approximately 71–75 kg (11 stone 2 lbs to 11 stone 10 lbs). However, "average" is different from "healthy". A healthy weight at this height depends on individual factors including age, muscle mass, bone density, and overall health. Use our free BMI calculator to find your personal healthy weight range, which will give you a more accurate picture than population averages alone. The NHS recommends a BMI between 18.5 and 24.9 for most adults, with lower thresholds for those of South Asian, Chinese, Black African, or Black Caribbean heritage.

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" Females
For a woman who is 5'6" (168 cm) tall, the healthy weight range according to NHS guidelines is approximately 50–67 kg (7 stone 12 lbs to 10 stone 8 lbs). This corresponds to a BMI of 18.5 to 24.9. However, this range varies depending on individual factors:
- Muscle mass: Athletes and very active women may weigh more within a healthy range because muscle is denser than fat
- Bone structure: Frame size (small, medium, or large) affects ideal weight
- Age: Metabolism and body composition naturally change with age
- Ethnicity: South Asian, Chinese, Black African, and Black Caribbean women may have lower healthy BMI thresholds (18.5–22.9) due to higher cardiovascular risk at standard BMI levels
Our free weight converter can help you switch between kg, stone, and pounds to find your target range in your preferred measurements.

When to Seek Health Advice About Weight
If your weight is significantly above or below the healthy range for your height, or if you're concerned about your health, speak to your GP. They can assess your individual circumstances, take into account your medical history, and provide personalised weight management advice. Your GP can also discuss whether prescription weight loss support might be appropriate if needed. Remember that weight is just one health marker — blood pressure, cholesterol, fitness level, and how you feel day-to-day all matter too.
You can also use our free BMI calculator on this page to instantly check where your current weight falls on the NHS scale and understand what it means for your health.
