What's the Average Weight for UK Men?
The average UK man weighs approximately 85.7 kg (13 stone 7 pounds), with an average height of 175.3 cm (5 feet 9 inches). This gives an average BMI of around 27.9, which falls into the overweight category according to NHS guidance. However, average weight and healthy weight are different things — knowing where you fall on the health spectrum requires understanding your personal BMI and waist measurement, not just how you compare to the national average. This UK health guide explains what the data shows and how to assess your own weight in context.

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 UK Men's Weight — The Numbers
Based on the most recent Office for National Statistics (ONS) data:
- Average weight: 85.7 kg (13 stone 7 lbs)
- Average height: 175.3 cm (5 feet 9 inches)
- Average BMI: 27.9
- Approximately 67% of UK men are overweight or obese (BMI 25+)
- Approximately 32% of UK men are obese (BMI 30+)
These figures show a shift over the past two decades — average weights have increased. The average UK man in the 1990s weighed roughly 79 kg; today that figure is over 85 kg. This reflects broader trends in sedentary lifestyles, dietary patterns, and portion sizes across the UK population.

Healthy Weight for Men — What Does NHS Guidance Say?
Being at the average weight does not necessarily mean being at a healthy weight. According to NHS guidance, a healthy BMI range is 18.5 to 24.9 for all adults. For a man of average UK height (175.3 cm), this corresponds to a healthy weight range of approximately 57 kg to 76 kg (9 stone to 12 stone). This means the average UK man is above the healthy weight range by approximately 10 kg. Use our free BMI calculator to check your personal healthy weight range — it factors in your exact height and shows where you stand relative to NHS thresholds. You can also use our weight converter to switch between kg, stone, and pounds instantly.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What's the difference between average weight and healthy weight?
Average weight is what most people weigh — the statistical mean. Healthy weight is what NHS guidance recommends for your height based on disease risk. The average UK man is overweight by NHS standards, but this doesn't mean all men at average weight have health problems. Individual factors like muscle mass, fitness level, and family history matter too.
How much should an average UK man weigh?
For a man of average UK height (175.3 cm), a healthy weight range is approximately 57–76 kg (9–12 stone). This gives a BMI of 18.5–24.9, which is the NHS healthy range. Your exact healthy weight depends on your individual height, frame size, and muscle mass. A GP can advise on your personal target.
Is the average UK man's weight increasing?
Yes. Average weight among UK men has increased significantly over the past 30 years, from roughly 79 kg in the 1990s to 85.7 kg today. This reflects changes in activity levels, diet, and portion sizes. The NHS notes that two-thirds of UK men are now overweight or obese.
How do I know if my weight is healthy for my height?
Calculate your BMI using our free BMI calculator on this page — enter your height and weight, and it instantly shows whether you fall into the healthy, overweight, or obese range according to NHS guidelines. You should also measure your waist circumference — NHS guidance recommends men keep waist measurements below 94 cm (37 inches).
Should I try to reach the average weight?
Not necessarily. The goal should be to reach a healthy weight for your height, not the average. If you're above the average weight and your BMI is above 25, speaking with your GP about weight management options — including lifestyle changes or, in some cases, prescription support — is a sensible step.
