What Is the Average Weight for UK Men?
The average weight for UK adult men is approximately 85.7 kg (13 stone 7 lbs). However, average does not mean healthy — understanding where your weight falls on the NHS health spectrum is what matters. This guide explains current UK male weight statistics, healthy weight ranges for different heights, and how to assess your personal weight health using evidence-based tools and UK health 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.
UK Male Weight Statistics and Healthy Ranges
According to the latest UK Office for National Statistics (ONS) data, the average UK adult man weighs around 85.7 kg (13 stone 7 lbs) and stands approximately 175.3 cm (5 feet 9 inches) tall. This gives an average BMI of approximately 27.9, which falls in the overweight category according to NHS guidelines (BMI 25–29.9). However, healthy weight varies significantly by height, frame size, and muscle mass.
According to NHS guidelines, a healthy weight for adult men is a BMI between 18.5 and 24.9. For a man of average UK height (5 feet 9 inches / 175 cm), this corresponds to a healthy weight range of approximately 56 kg to 76 kg (8 stone 11 lbs to 11 stone 12 lbs). Men of South Asian, Chinese, Black African, or Black Caribbean heritage may have lower healthy weight thresholds due to higher health risks at the same BMI.

Why Average Weight Matters Less Than Healthy Weight
Weight statistics are useful for population-level understanding but should never be used to judge your individual health. Two men of identical weight can have completely different health profiles depending on muscle mass, fat distribution, age, fitness level, and medical history. BMI provides a useful screening tool, but it does not account for muscle versus fat — an athlete may have a high BMI but excellent health.
The best approach is to focus on your personal healthy weight range for your height, which you can calculate using our free BMI calculator on this page. If you are concerned about your weight or health, your GP can provide personalised guidance based on your individual circumstances, including any weight-related health conditions.

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?
It depends on height. 85.7 kg is the average for UK men but falls in the overweight category for someone of average height (5'9"). For a taller man, it may be within the healthy range. Use the free BMI calculator on this page to check if 85.7 kg is healthy for your specific height.
What's the healthy weight range for a 5 foot 10 inch man?
For someone 5'10" (178 cm), the NHS healthy weight range is approximately 59 kg to 80 kg (9 stone 4 lbs to 12 stone 8 lbs). Individual results vary based on muscle mass and frame size. Your GP can advise on the best weight range for your personal health.
How do UK male weight statistics compare to other countries?
UK men weigh slightly more on average than many European countries but less than the USA. Average weight varies by diet, activity levels, and healthcare systems. NHS guidance focuses on healthy BMI ranges rather than comparing to other nations.
Should men aim for the "average" weight if it's not their healthy weight?
No. The average weight is just a statistical figure — it does not equal healthy weight. Focus instead on reaching your personal healthy weight range for your height using NHS BMI guidelines. This is what matters for your long-term health.
Can I use the weight converter to check my healthy weight range?
Yes. Our free weight converter lets you instantly convert between kilograms, stone, and pounds. Combine it with our BMI calculator above to find your personal healthy weight range based on your height and NHS guidelines.
