Average Weight for Men in the UK — BMI Context
The average UK man weighs approximately 85.7 kg (13 stone 7 lbs) at an average height of 175.3 cm (5 ft 9 in). However, average weight and healthy weight are not the same thing. According to NHS guidelines, a healthy weight range depends on your individual height and BMI, which falls between 18.5 and 24.9. Understanding where you fit within the healthy weight range for your height is more important than comparing yourself to the national average. Use our free BMI calculator above to find your personal healthy weight range.

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.
Healthy Weight Range for Men by Height — BMI-Based Guidance
Your ideal body weight depends on your height, not just age or gender. The NHS uses BMI (body mass index) to define healthy weight ranges. A healthy BMI sits between 18.5 and 24.9, and for men this translates into specific weight targets based on height.
- 5 ft 6 in (168 cm): Healthy weight range is approximately 56–76 kg (8 st 10 lbs – 11 st 13 lbs)
- 5 ft 8 in (173 cm): Healthy weight range is approximately 55–74 kg (8 st 8 lbs – 11 st 8 lbs)
- 5 ft 10 in (178 cm): Healthy weight range is approximately 59–80 kg (9 st 4 lbs – 12 st 8 lbs)
- 6 ft 0 in (183 cm): Healthy weight range is approximately 62–85 kg (9 st 11 lbs – 13 st 5 lbs)
These ranges reflect the weight for height UK standards set by the NHS. If your current weight falls above these ranges, your BMI may be in the overweight or obese category. If below, you may be underweight. Individual factors like muscle mass, bone density, and fitness level also matter — BMI is a screening tool, not a complete health picture.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is the average weight of a UK man?
The average UK adult man weighs approximately 85.7 kg (13 stone 7 lbs) at an average height of 175.3 cm (5 ft 9 in). This data comes from the Office for National Statistics. However, average and healthy are different — your healthy weight depends on your individual height and BMI, not the national average.
What is the healthy weight range for a man 5 ft 10 in tall?
For a man 178 cm (5 ft 10 in) tall, a healthy BMI of 18.5–24.9 corresponds to approximately 59–80 kg (9 st 4 lbs – 12 st 8 lbs). This range reflects NHS guidelines. Use our BMI calculator above to check your personal healthy weight range based on your exact height.
Is there a difference between average weight and healthy weight?
Yes. Average weight is what UK men typically weigh (85.7 kg). Healthy weight is the range where BMI sits between 18.5–24.9, which varies by height. Many UK men are above their healthy weight range, which is why average and healthy weights differ.
How do I know if my weight is healthy?
Calculate your BMI using our free calculator on this page. A BMI between 18.5 and 24.9 is considered healthy by the NHS. You can also compare your weight to the healthy weight range for your specific height. Your GP can provide personalised guidance.
What if I'm above the healthy weight range for my height?
If your current weight is above the healthy range, small changes can help — reducing calorie intake gradually, increasing physical activity, and tracking progress with our free progress tracker. Start with your GP for personalised advice before making significant health changes.
