How Much Does The Average Male Weigh?
The average UK adult male weighs approximately 85.7 kg (13 stone 7 lbs), but healthy weight depends entirely on your height, not a single number. According to NHS guidelines, a healthy weight for men falls within a BMI range of 18.5 to 24.9. What matters most is whether your weight is healthy for your individual height and build. Use our free BMI calculator above to check where you fall, and explore the healthy weight ranges for your specific height in the table below.

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 By Height For Men
Your ideal weight depends on your height. The NHS uses BMI (body mass index) to define healthy weight ranges, which is a simple calculation of weight divided by height squared. For most adult men, a healthy BMI sits between 18.5 and 24.9. Below is a practical guide showing the healthy weight range for common male heights in both metric and imperial measurements:
- 5ft 6in (168 cm): 55–74 kg (8st 9lbs – 11st 8lbs)
- 5ft 8in (173 cm): 55–74 kg (8st 9lbs – 11st 8lbs)
- 5ft 10in (178 cm): 59–79 kg (9st 4lbs – 12st 6lbs)
- 6ft (183 cm): 64–86 kg (10st 1lb – 13st 7lbs)
- 6ft 2in (188 cm): 69–92 kg (10st 13lbs – 14st 6lbs)
For men of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends slightly lower healthy weight thresholds due to higher health risks at lower BMI levels. Use our weight converter to switch between kg, stone, and pounds instantly.

Factors That Affect Your Individual Healthy Weight
While average weight data is useful context, your personal healthy weight depends on several individual factors that BMI alone doesn't capture. Muscle mass weighs more than fat, so a muscular or athletic man may have a higher BMI but still be in excellent health. Frame size varies — some men naturally carry more weight on a larger skeletal frame. Age affects body composition; older men tend to lose muscle mass naturally. Ethnicity influences health risk at different weights, as noted above. Rather than fixating on a single number, focus on how you feel, your energy levels, and your health markers like blood pressure and cholesterol. Your GP can provide personalised advice about what weight is right for your unique circumstances.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is the average weight of a UK male?
The average UK adult male weighs approximately 85.7 kg (13 stone 7 lbs) and stands around 175.3 cm (5ft 9in) tall. However, average is not the same as healthy. Your healthy weight depends on your height, muscle mass, and individual health factors, not the average.
What's the healthy weight range for a 5ft 10in man?
For a man who is 5ft 10in (178 cm) tall, the healthy BMI range of 18.5–24.9 corresponds to approximately 59–79 kg (9st 4lbs–12st 6lbs). This assumes average frame size. Your GP can advise on what's healthy for your specific build.
Should I aim for the exact number on a BMI chart?
No. BMI is a screening tool, not a prescription. Your healthy weight range is a band, not a single target. Focus on sustainable habits like balanced eating and regular activity, and track your progress using our free progress tracker.
How much should I weigh if I'm 6 feet tall?
At 6ft (183 cm), a healthy BMI of 18.5–24.9 corresponds to roughly 64–86 kg (10st 1lb–13st 7lbs). This is the NHS healthy weight range for your height, though individual factors like muscle mass and frame size mean your personal ideal may vary.
Does muscle weight more than fat?
Yes. Muscle is denser and weighs more per volume than fat. A muscular man may weigh more than average for his height but still be in excellent health. BMI doesn't distinguish between muscle and fat, which is one of its limitations. Consider waist measurement alongside BMI for a fuller picture.
