Average Weight of Women 5'6 and Healthy Weight Range
For a woman who is 5'6 (168 cm), the average UK weight is approximately 71 kg (11 stone 3 lbs). However, average weight and healthy weight are different things. A healthy weight range for this height, based on NHS guidelines and BMI context, falls between approximately 55 kg (8 stone 9 lbs) and 75 kg (11 stone 11 lbs). Understanding where your weight sits within these ranges helps you assess your personal health status accurately.

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 Framework
The healthy weight range for a woman who is 5'6 tall is determined by achieving a BMI (body mass index) between 18.5 and 24.9 — the NHS healthy weight category. For this height, this translates to:
- Lower bound: 55 kg (8 stone 9 lbs) — BMI 18.5
- Upper bound: 75 kg (11 stone 11 lbs) — BMI 24.9
This ideal body weight range applies to most women of this height. However, the actual healthy weight for height uk can vary based on individual factors like muscle mass, bone density, and frame size. Use our free BMI calculator above to check your personal BMI instantly. If your weight falls between these figures, you're within the NHS healthy weight range. Above 75 kg puts you into the overweight category (BMI 25–29.9), while below 55 kg indicates underweight status.

Using the BMI Calculator for Personalised Assessment
Rather than relying on average figures alone, calculating your healthy weight calculator result gives you a clearer picture of your personal health status. Enter your height (5'6) and current weight into the BMI calculator on this page — it will instantly show you your BMI category and how it compares to the healthy weight range.
Remember that BMI is a screening tool with limitations. It does not distinguish between muscle and fat, so athletes or those with high muscle mass may have a higher BMI but still be in good health. Waist circumference also matters — for women, a waist over 80 cm (31.5 inches) suggests increased health risk regardless of BMI. If you have concerns about your weight or health, your GP can provide personalised advice tailored to your individual circumstances.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is the average weight for a woman who is 5'6?
The average UK weight for women around 5'6 is approximately 71 kg (11 stone 3 lbs). However, this average does not mean it is the healthy weight for this height. Healthy weight depends on individual factors like muscle mass and frame size, which is why BMI provides a more useful framework.
What is considered a healthy weight for someone 5'6?
A healthy weight for a woman 5'6 is approximately 55–75 kg (8 stone 9 lbs to 11 stone 11 lbs), based on achieving a BMI between 18.5 and 24.9 according to NHS guidelines. Individual healthy weight varies, so consult your GP for personalised advice.
Is 70 kg a healthy weight for a woman 5'6?
At 70 kg, a woman 5'6 would have a BMI of approximately 22.6, which falls comfortably within the NHS healthy weight range (18.5–24.9). This weight is considered healthy for this height, though individual health depends on many factors beyond weight alone.
How do I find my ideal weight for my height?
Use our free healthy weight calculator (the BMI calculator on this page) to check your personal BMI. Enter your height and weight — if your BMI falls between 18.5 and 24.9, you're in the healthy range. Your GP can also discuss your ideal weight based on your medical history.
Does average weight matter if I'm trying to lose weight?
Average weight figures are less important than your personal BMI and health goals. Two women at the same height and weight can have very different body compositions. Focus on achieving a BMI within the healthy range (18.5–24.9) and improving your overall health markers rather than matching population averages.
