What Is the Average Male Weight in the UK?
The average male weight in the UK is approximately 85.7 kg (13 stone 7 lbs), based on the latest Office for National Statistics data. However, average weight doesn't mean healthy weight — and individual weight varies significantly by age, height, and body composition. Understanding where you sit relative to the average is less important than understanding whether your weight is healthy for your personal height and circumstances. This UK health guide explains current statistics, healthy weight ranges, and how to assess your own weight 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.
Average Male Weight Statistics in the UK
Current UK male weight data (ONS):
- Average weight: 85.7 kg (13st 7lbs)
- Average height: 175.3 cm (5ft 9in)
- Average BMI: 27.9 (overweight category)
These figures represent a significant increase over the past two decades. The average male weight has risen by approximately 3–4 kg since the early 2000s, reflecting broader trends in sedentary lifestyles and dietary patterns across the UK.
It's important to note that average does not equal healthy. Since the average UK male BMI falls into the overweight category (25–29.9), many men are above a healthy weight range for their height. This is why NHS guidance emphasises assessing your personal weight within your own height and health context, rather than comparing yourself to population averages. Use our free BMI calculator to find your personal healthy weight range.

Healthy Weight Range for UK Men
According to NHS guidance, a healthy BMI for adults is between 18.5 and 24.9. For a man of average UK height (175 cm / 5ft 9in), this translates to a healthy weight range of approximately 56–76 kg (8st 12lbs to 11st 13lbs).
Factors that influence your ideal weight include muscle mass, bone density, age, and overall fitness level. A man who is athletic or heavily muscled may have a higher weight while maintaining excellent health. Conversely, excess weight concentrated around the stomach (waist circumference over 94 cm or 37 inches for men) carries higher health risks even at the same BMI. Our weight converter tool helps you find your healthy range in your preferred units, and our BMI calculator provides personalised guidance for your height.
Weight management in the UK is supported by NHS Tier 1 services including digital tools and community programmes, with access to specialist services (Tier 3) for those with significant obesity or weight-related health conditions. For men interested in weight loss support, options range from lifestyle changes — diet, exercise, and behaviour modification — to prescription medications such as GLP-1 injections (Wegovy or Mounjaro) available through NHS specialist services or private prescribing following clinical assessment.
Track your weight progress over time using our free progress tracker, which helps you monitor trends and celebrate small milestones. If you're considering weight loss, remember that even a 5–10% reduction in body weight can bring meaningful health benefits including lower blood pressure, improved blood sugar control, and reduced joint strain.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
Is 85.7 kg a healthy weight for men in the UK?
Not necessarily. The average male weight of 85.7 kg results in an average BMI of 27.9, which falls into the overweight category. A healthy BMI (18.5–24.9) depends on your personal height. For a man of average UK height (175 cm), a healthy weight is 56–76 kg. Use our BMI calculator to find your personalised healthy range.
What is considered overweight for a UK male?
According to NHS guidance, a BMI of 25–29.9 is classified as overweight. This depends on your height. For example, a 5ft 9in man would be overweight at approximately 76–82 kg. Waist circumference also matters — a waist over 94 cm (37 inches) indicates increased health risk even at the same BMI.
How has average male weight changed in the UK?
Average male weight has increased by 3–4 kg over the past 20 years, reflecting lifestyle and dietary changes. Obesity rates among UK men have also risen — approximately 30% of UK men are now classified as obese (BMI 30+), up from around 15% in the 1990s.
What health risks are associated with excess male weight?
Excess weight increases risk of type 2 diabetes, heart disease, high blood pressure, certain cancers, and joint problems. Even modest weight loss of 5–10% can reduce these risks significantly. Speak to your GP about weight management options including lifestyle changes and, if appropriate, prescription support.
How can I check if my weight is healthy for my height?
