What Is The Average Weight Of A Man In The UK?
The average weight of a man in the UK is approximately 85.7 kg (13 stone 7 pounds), based on the latest Office for National Statistics (ONS) data. However, this average does not tell you whether your own weight is healthy for your height โ that depends on your BMI, body composition, and individual health factors. Using our free BMI calculator above, you can check whether your weight falls within a healthy weight range for your specific height and age.

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/mยฒ).
While BMI isn't a perfect measure โ it doesn't account for muscle mass, bone density, or fat distribution โ 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 โ 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 Male Weight Data And Healthy Weight Ranges
According to ONS figures, the average UK man weighs 85.7 kg (13 stone 7 pounds) and stands approximately 175.3 cm (5 feet 9 inches) tall. This gives an average BMI of around 27.9, which falls in the overweight category according to NHS guidelines. However, average weight does not equal healthy weight. The NHS defines a healthy weight range as a BMI of 18.5 to 24.9. For a man of average UK height (175 cm), this translates to a healthy weight range of approximately 56.6 kg to 76 kg (8 stone 13 pounds to 11 stone 13 pounds). Your ideal body weight within this range depends on factors including muscle mass, bone density, and frame size.

Factors That Affect Ideal Weight For Men
While healthy weight range provides a useful guideline, several factors influence what weight is ideal for you personally. Muscle mass weighs more than fat โ athletic men may have a higher weight but lower body fat percentage than sedentary men at the same BMI. Frame size varies: larger-framed men naturally weigh more than smaller-framed men at the same height. Age affects metabolism and muscle loss โ older men may need slightly different targets. Ethnicity also matters: the NHS recommends lower BMI thresholds (18.5 to 22.9) for men of South Asian, Chinese, Black African, or Black Caribbean heritage due to higher health risks at lower weights. Your GP can provide personalised guidance on what weight is appropriate for your individual health profile.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is the healthy weight range for a UK man who is 5 feet 10 inches tall?
At 5 feet 10 inches (178 cm), a healthy BMI of 18.5 to 24.9 corresponds to a weight range of approximately 58.6 kg to 78.7 kg (9 stone 3 pounds to 12 stone 5 pounds). Use our BMI calculator above to check your personal healthy range โ remember that ideal weight varies by muscle mass and frame size.
Is the average UK male weight of 85.7 kg considered overweight?
At 85.7 kg and average UK male height of 175 cm, the BMI is approximately 27.9, which falls in the overweight category (BMI 25โ29.9) according to NHS guidelines. However, "overweight" is a BMI classification, not a health judgment โ many people at this weight are healthy. Your GP can assess your individual health status.
How do I know my ideal weight as a man?
Ideal weight depends on height, muscle mass, bone density, and frame size. The NHS healthy weight range (BMI 18.5โ24.9) provides a starting point. For personalised guidance, calculate your BMI using our free calculator on this page, then discuss the result with your GP โ they can advise whether your current weight is healthy for you.
Does muscle affect average weight calculations?
Yes, significantly. Muscle weighs more than fat, so athletic men with high muscle mass may weigh more than average but have lower body fat and better health markers. BMI does not distinguish muscle from fat, which is why it's useful to combine BMI assessment with waist circumference and discussion with your GP.
Should I aim for the average UK male weight of 85.7 kg?
No โ the average is not a health target. What matters is your healthy weight range for your height, not the national average. Many UK men weigh more or less than 85.7 kg and are perfectly healthy. Use the weight converter on this page to see your healthy range, and speak to your GP if you have concerns about your weight.
