What's the Average Weight for UK Men?
The average UK man weighs approximately 85.7kg, which is equivalent to 13 stone and 7 pounds. This figure comes from Office for National Statistics (ONS) data and represents adult men across the UK. However, average weight is very different from ideal or healthy weight — knowing where you fall relative to the average is useful context, but what matters for your health is whether your weight sits within a healthy range for your height. Use our free BMI calculator to find out if your personal weight is in a healthy range according to NHS 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.
How Does Average Man Weight Compare to Healthy Weight?
The average UK man weight of 85.7kg does not automatically mean it's a healthy weight — it simply reflects the population mean. According to NHS guidelines, a healthy weight depends entirely on your height. For context, the average UK man is approximately 175.3cm (5ft 9in) tall, which gives an average BMI of approximately 27.9 — this falls in the overweight category rather than the healthy weight range.
Healthy weight ranges for UK men by height:
- 5ft 6in (168cm): healthy weight 54–72kg (8st 8lbs – 11st 5lbs)
- 5ft 9in (175cm): healthy weight 57–76kg (9st 0lbs – 12st 0lbs)
- 5ft 10in (178cm): healthy weight 59–79kg (9st 4lbs – 12st 6lbs)
- 6ft 0in (183cm): healthy weight 62–83kg (9st 11lbs – 13st 1lbs)
These ranges are based on a healthy BMI of 18.5 to 24.9. Your GP or a healthcare professional can provide personalised weight management guidance specific to your height, age, and health conditions.

Understanding Your Weight in UK Context
UK health guidance emphasises that weight alone doesn't tell the full story — your BMI, waist circumference, and overall health profile matter far more than how you compare to the average man weight. Many men at or above the average weight are perfectly healthy, whilst others may benefit from weight management support. If you're concerned about your weight or health, your GP can assess your individual situation and discuss whether weight management is appropriate for you.
Use our free weight converter to check your weight in stone, pounds, or kilograms, and use the BMI calculator on this page to see where your personal weight sits relative to NHS healthy weight ranges. These tools provide NHS-aligned guidance tailored to your height.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is the average weight of a UK man?
According to Office for National Statistics data, the average UK adult man weighs approximately 85.7kg (13 stone 7 pounds). The average UK man is also approximately 175.3cm (5ft 9in) tall. However, this average doesn't indicate whether a weight is healthy — that depends on individual height, age, and health profile.
Is the average man weight considered healthy?
The average UK man weight of 85.7kg results in an approximate BMI of 27.9, which falls in the overweight category according to NHS guidelines. This suggests that, as a population average, UK men are slightly above the healthy weight range. However, individual circumstances vary — your GP can advise whether your personal weight is healthy for you.
How do I know if my weight is healthy?
Use the NHS BMI calculator (available free on this page) with your height and weight to find your BMI. A healthy BMI is 18.5 to 24.9. For men of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends a lower healthy range of 18.5 to 22.9. Your GP can also discuss your waist circumference and overall health context.

This range represents the NHS-recommended weight bracket for this height. Your ideal weight within this range depends on factors including muscle mass and frame size.
How can I manage my weight if I'm above average?
If you're concerned about your weight, start by speaking to your GP, who can assess your health and discuss options. The NHS recommends a sustainable weight loss rate of 0.5–1kg per week, achieved through a combination of reduced-calorie diet and increased physical activity.
