Average Weight For Male — UK Health Context
The average weight for a UK adult male is approximately 85.7 kg (13 stone 7 lbs), but what matters more than the average is whether your weight falls within a healthy range for your height. According to NHS guidelines, a healthy weight is defined by a BMI of 18.5 to 24.9, which varies significantly depending on how tall you are. This guide explains healthy weight ranges for men, how BMI works, and how to find the ideal body weight for your individual height and frame.

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 body weight depends entirely on your height. The NHS healthy weight range is a BMI of 18.5 to 24.9, which translates to different weights for different heights. For example, at 5ft 9in (175 cm), a man falls within the healthy weight range at approximately 65–82 kg (10st 3lbs to 12st 12lbs). At 5ft 6in (168 cm), the range is roughly 52–70 kg (8st 3lbs to 11st 0lbs).
Use our free BMI calculator above to find your exact healthy weight range — simply enter your height and the calculator will show you the weight for height UK guidelines that apply to you. For men of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends slightly lower thresholds, with a healthy BMI starting at 18.5 but overweight beginning at 23 rather than 25.
- 5ft 6in (168 cm): Healthy range 52–70 kg (8st 3lbs–11st 0lbs)
- 5ft 8in (173 cm): Healthy range 55–74 kg (8st 10lbs–11st 10lbs)
- 5ft 10in (178 cm): Healthy range 59–79 kg (9st 4lbs–12st 6lbs)
- 6ft (183 cm): Healthy range 62–84 kg (9st 11lbs–13st 2lbs)

How To Find Your Ideal Weight Using BMI
The healthiest approach is to use the NHS BMI framework rather than chasing an arbitrary "ideal" weight. BMI provides a weight for height UK standard that accounts for your individual stature. Our weight converter helps you switch between kg, stone, and pounds, making it easy to understand what healthy weight ranges mean in the measurements you're familiar with.
Remember that BMI is a useful screening tool but has limitations — it doesn't distinguish between muscle and fat, so athletes may have a higher BMI despite low body fat. If you're concerned about whether your weight is healthy for you, your GP can provide personalised advice based on your overall health, not just a number on the scales.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What's the average UK weight for men?
The average weight for UK adult males is approximately 85.7 kg (13 stone 7 lbs) according to recent ONS data. However, average is not the same as healthy — many UK men are overweight. Your healthy weight depends on your height, not the average.
What's a healthy weight for a 5ft 10in man?
At 5ft 10in (178 cm), the NHS healthy weight range is approximately 59–79 kg (9 stone 4 lbs to 12 stone 6 lbs). This corresponds to a BMI of 18.5 to 24.9. Use our free BMI calculator to find your exact healthy range for your height.
How do I calculate ideal body weight?
The easiest method is to use a BMI calculator, which shows the weight range for your height according to NHS guidelines. Alternatively, you can use the formula: healthy BMI range 18.5–24.9 × height in metres squared. Individual ideal weight varies based on muscle mass and frame size.
Is the average weight the same as healthy weight?
No. Average describes what most people weigh; healthy weight describes what supports good health. Because many UK adults are overweight, the average is higher than the healthy range. Your GP or our BMI calculator can help you find the healthy weight range for your height.
Should men aim for a specific weight number?
Rather than targeting a specific weight, aim for a healthy BMI of 18.5–24.9 according to NHS guidelines. This gives you a range rather than a single number, accounting for muscle mass and individual variation. Combined with regular physical activity, this approach is more sustainable than fixating on one weight figure.
