What's the Average Weight for a 5'11" Male in the UK?
The average weight for a 5'11" (178 cm) male in the UK is approximately 85.7 kg (13 stone 7 lbs). However, average weight is not the same as healthy weight. For your height, the NHS healthy weight range is between 69 kg and 93 kg (10 stone 13 lbs to 14 stone 8 lbs), based on a healthy BMI of 18.5 to 24.9. Your ideal weight depends on factors like muscle mass, frame size, and overall health — not just height.

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 and BMI for 5'11" Males
For a 5'11" (178 cm) male, the healthy weight range according to NHS guidelines is 69–93 kg (10 stone 13 lbs to 14 stone 8 lbs). This range corresponds to a BMI of 18.5 to 24.9, which the NHS classifies as a healthy weight.
The average UK male weighs around 85.7 kg, which falls comfortably within this healthy range. However, weight alone doesn't tell the full story. A BMI of 25–29.9 would be considered overweight, and 30 or above would be classified as obese. You can calculate your personal BMI using our free BMI calculator above to see exactly where your weight sits for your height. Remember that BMI has limitations — it doesn't account for muscle mass, so athletes or very muscular individuals may have a higher BMI despite being fit.

Factors Affecting Your Ideal Weight
Your ideal weight at 5'11" isn't a fixed number — it varies based on several factors. Muscle mass is significant: muscle weighs more than fat, so two men at the same height and weight can look very different. Frame size (small, medium, or large) also matters. Men with larger frames may sit naturally at the higher end of the healthy range, while those with smaller frames may sit lower. Age affects metabolism and body composition; older men often have more body fat at the same weight. Your ethnicity may also influence health risk thresholds — South Asian and Black African men face higher health risks at the same BMI as white men, according to NHS guidance. For personalised advice about your ideal weight, consult your GP or use our free weight converter to explore different weights in both metric and imperial units.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What's the healthy weight range for a 5'11" male?
The NHS healthy weight range for a 5'11" (178 cm) male is 69–93 kg (10 stone 13 lbs to 14 stone 8 lbs), based on a BMI of 18.5 to 24.9. The average UK male at this height weighs around 85.7 kg, which sits comfortably within this range. Check your personal BMI using our free calculator above.
Is 85 kg overweight for a 5'11" man?
No, 85 kg is not overweight for a 5'11" male — it's actually close to the average UK weight for this height and falls solidly within the healthy weight range. This corresponds to a BMI of approximately 24, which is firmly in the healthy category. However, individual health depends on many factors beyond weight alone.
What's the difference between average and healthy weight?
Average weight is simply what most people weigh. Healthy weight is based on medical guidelines like BMI, which considers both height and weight to assess disease risk. The average UK male at 5'11" (85.7 kg) happens to be in the healthy range, but average doesn't always equal healthy. Use our free BMI calculator to find your personal healthy range.
How do I know if I'm at a healthy weight for my height?
Calculate your BMI — the simplest method is using our free BMI calculator on this page. For a 5'11" male, a BMI between 18.5 and 24.9 is healthy. However, also consider waist measurement (NHS recommends under 94 cm for men) and discuss your personal weight goals with your GP.
Does muscle mass affect the ideal weight for 5'11" males?
Yes, significantly. Muscle weighs more than fat, so two 5'11" men at the same weight can have very different body compositions. BMI doesn't distinguish muscle from fat, which is why it has limitations. Your GP can discuss whether your weight is appropriate for your individual health and fitness level.
