What's the Healthy Weight Range for a 5'11" Man?
For a man who is 5'11" (180 cm), the healthy weight range according to NHS guidelines is approximately 65–87 kg (10st 4lbs–13st 9lbs). This range represents a BMI of 18.5 to 24.9, which the NHS classifies as healthy weight for adults. However, the ideal body weight for you personally depends on factors like muscle mass, frame size, and overall fitness. Use our free BMI calculator above to find your exact BMI and see where your current weight falls within the healthy weight range framework.

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 at 5'11" — BMI Breakdown
At 5'11" (180 cm tall), here's your healthy weight range based on NHS BMI guidelines:
- Lower healthy limit (BMI 18.5): 65 kg (10st 4lbs / 143 lbs)
- Upper healthy limit (BMI 24.9): 87 kg (13st 9lbs / 192 lbs)
- Optimal mid-range: Around 76 kg (12st 0lbs / 168 lbs)
The average UK weight for men is approximately 85.7 kg (13st 7lbs), which falls slightly into the overweight category at your height. However, BMI doesn't account for muscle mass—a muscular man may have a higher BMI without excess fat. Your GP or our free BMI calculator can help you determine if your weight is healthy for your individual circumstances. Remember: ideal weight varies based on frame size, fitness level, and personal health factors.

Using the BMI Calculator to Find Your Personal Healthy Weight
Rather than relying on averages alone, calculate your personal BMI using our free calculator above. Simply enter your height (5'11") and current weight in kg, stone, or pounds, and the tool will instantly show your BMI category and healthy weight range. This personalised approach is more useful than average weight for height UK statistics because it accounts for your individual health context. If your BMI falls outside the healthy range (18.5–24.9), your GP can advise on safe, sustainable steps forward. For men looking to lose weight, the NHS recommends a gradual approach of 0.5–1 kg per week alongside dietary changes and increased activity.

The average UK man weight is approximately 85.7 kg (13st 7lbs), though this varies widely. At 5'11", this average actually falls slightly into the overweight BMI category (25–29.9). However, average doesn't mean ideal or healthy—it depends on your individual fitness, muscle mass, and health status.

Yes, 80 kg (12st 8lbs) at 5'11" gives a BMI of approximately 25.1, which falls into the overweight category but very close to the upper healthy limit. It's within a reasonable range, though slightly over the NHS ideal band (18.5–24.9). Your GP can give personalised advice.
