What Is Average Size For A Man in the UK?
The average UK adult man weighs approximately 85.7 kg (13 stone 7 lbs) and stands around 175.3 cm (5 feet 9 inches) tall. According to NHS health information, this gives an average BMI of approximately 27.9, which falls into the overweight category. However, "average" does not mean "healthy" — healthy weight ranges vary based on individual height, age, and body composition. Understanding where you fit within NHS health guidance can help you make informed decisions about your wellbeing.

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.
UK Average Measurements for Men
Average UK male statistics (based on recent health surveys):
- Average weight: 85.7 kg (13 stone 7 lbs)
- Average height: 175.3 cm (5 feet 9 inches)
- Average BMI: 27.9 (overweight category)
- Percentage of UK men who are overweight or obese: approximately 67%
These figures come from national health data and represent the middle point — not a target weight. Many UK men are heavier, and many are lighter. Your own healthy weight depends on your individual height, age, fitness level, and any underlying health conditions. Use our free BMI calculator above to check where your weight sits relative to NHS healthy weight ranges. The weight converter tool on this page can also help you switch between kg, stone, and pounds to understand these averages in your preferred measurements.

Healthy Weight Range for Men
For an average-height UK man at 175 cm (5 feet 9 inches), a healthy BMI range of 18.5 to 24.9 corresponds to a weight between approximately 56.6 kg (8 stone 13 lbs) and 76.2 kg (12 stone) according to NHS guidance. If you're significantly above or below this range, it's worth speaking with your GP about your personal health. Men of South Asian, Chinese, Black African, or Black Caribbean heritage have different NHS thresholds — healthy BMI starts at 18.5 but overweight begins at 23.0 rather than 25.0. These adjusted thresholds reflect different health risk patterns in these populations. Your GP can provide personalised guidance based on your individual health picture.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is considered overweight for a man in the UK?
According to NHS guidance, a BMI of 25.0 to 29.9 is classified as overweight. For an average-height man at 175 cm, this roughly corresponds to a weight between 76.2 kg (12 stone) and 90.8 kg (14 stone 4 lbs). However, BMI does not account for muscle mass, so a very muscular man might fall into this range despite being in good health.
What is a healthy weight for a man 6 feet tall?
A man who is 6 feet (183 cm) tall has a healthy weight range of approximately 61.7 kg (9 stone 10 lbs) to 83.5 kg (13 stone 2 lbs) based on NHS BMI guidelines of 18.5 to 24.9. Your own healthy weight within this range depends on your body composition, fitness level, and overall health. Your GP can advise further.
How does average male weight compare across the UK?
The UK average male weight of 85.7 kg masks significant variation. Regional differences exist, and weight varies by age — men in their 40s and 50s tend to be heavier than men in their 20s. Approximately 67% of UK men are overweight or obese, meaning many fall above healthy weight ranges.
Should I worry if I'm heavier than the average man?
Being heavier than average does not automatically mean a health problem, but it's worth checking your BMI and discussing any concerns with your GP. Use our free BMI calculator to see where you sit relative to NHS healthy ranges. If you're in the overweight or obese category, your GP can discuss whether lifestyle changes or further support might be helpful.
Can I use average weight to determine my ideal weight?
Not really. Your ideal weight depends on your height, age, muscle mass, and overall health — not on what other men weigh. Use the weight converter and BMI calculator on this page to find your healthy weight range based on NHS guidance, then discuss any concerns with your GP for personalised advice.
