What's the Normal Weight for a 5ft 11in Male?
For an adult male who is 5ft 11in (180cm) tall, the healthy weight range according to NHS guidelines is approximately 69kg to 93kg (152lbs to 205lbs, or 10st 12lbs to 14st 7lbs). This range is based on achieving a BMI between 18.5 and 24.9, which the NHS classifies as a healthy weight. Your individual ideal body weight within this range depends on your frame size, muscle mass, and overall health. Use our free BMI calculator to check where your current weight sits and discover your personalised healthy weight range for your height and age.

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.
BMI-Based Healthy Weight Range for 5ft 11in Males
The NHS healthy weight range for a 5ft 11in (180cm) male is based on a BMI of 18.5 to 24.9. Here's the breakdown:
- Lower healthy range: 69kg (10st 12lbs) — BMI 18.5
- Upper healthy range: 93kg (14st 7lbs) — BMI 24.9
- Mid-range (average): 81kg (12st 10lbs) — BMI approximately 22.5
The average UK weight for men is around 85.7kg (13st 7lbs), which is slightly above the healthy range due to the prevalence of overweight and obesity. However, being within the 69–93kg range aligns with NHS guidelines for reduced risk of weight-related health conditions. If your weight falls outside this range, your GP can offer personalised guidance. Remember that BMI is a screening tool and does not account for muscle mass — athletes and those with significant muscle may have a higher BMI within a healthy range.

An 85kg weight for a 5ft 11in male gives a BMI of approximately 23.6, which falls within the NHS healthy weight range of 18.5–24.9. This is considered a healthy weight. However, individual health depends on many factors, so discuss your specific situation with your GP for personalised advice.
What's the average weight for a 5ft 11in UK male?
The average UK adult male weighs approximately 85.7kg (13st 7lbs), which is slightly above the NHS healthy weight range. This reflects that many UK adults are overweight. A weight of 69–93kg is the NHS-recommended healthy range for your height.
How do I calculate my ideal weight for 5ft 11in?
Your ideal weight depends on your frame size and muscle mass. The NHS healthy range is 69–93kg. Use our free BMI calculator to enter your height and weight and instantly see your BMI category. Your GP can also help determine your personalised ideal weight target.
What BMI should a 5ft 11in male aim for?
The NHS recommends a BMI of 18.5–24.9 for healthy adults. For a 5ft 11in male, this equals 69–93kg. A BMI in the mid-range (around 21–23) is often considered optimal, but the exact target depends on your individual health and medical history.
Can muscle affect what the scale shows for a 5ft 11in male?
Yes. Muscle weighs more than fat, so someone with high muscle mass may have a higher weight or BMI but lower body fat percentage. BMI does not distinguish between muscle and fat. If you're very muscular, discuss your weight with your GP rather than relying solely on BMI categories.
