5.11 Feet in Centimetres — What's Your Healthy Weight?
5.11 feet is exactly 180 centimetres. If you're this height, understanding your healthy weight range according to NHS guidelines is straightforward. Your height puts you slightly above the UK average for adult men. We'll show you what a healthy weight looks like at 5ft 11in, how different BMI categories apply to your height, and how you compare to typical UK measurements. Use our free BMI calculator and weight converter to explore your personal health context in both metric and imperial measurements.

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 5ft 11in (180cm)
According to NHS BMI guidelines, a healthy weight at 5ft 11in ranges from approximately 59.9kg to 80.3kg (9 stone 6lbs to 12 stone 8lbs). This is calculated using a BMI of 18.5 to 24.9, which the NHS considers healthy for most UK adults.
- Lower healthy limit: 59.9 kg (9 stone 6 lbs) — BMI 18.5
- Upper healthy limit: 80.3 kg (12 stone 8 lbs) — BMI 24.9
- Overweight threshold: 80.5 kg and above — BMI 25.0
This range assumes you're of white European, African or Caribbean descent. If you're of South Asian, Chinese, or Black African heritage, the NHS recommends slightly lower thresholds due to increased health risks at higher BMI levels. Our free BMI calculator can help you determine exactly where you fall within these categories instantly.

UK Context — How 5ft 11in Compares
At 5ft 11in (180cm), you're above the UK average height for adult men, which is approximately 5ft 9in (175cm). The UK average adult man weighs about 85.7kg (13 stone 7lbs), which would give a BMI of approximately 27.9 — in the overweight category. However, your individual healthy weight depends on your personal body composition, muscle mass, and overall health. Using the weight converter and BMI calculator on this page lets you quickly check what different weights mean for your health at your exact height, and track any weight changes over time with our free progress tracker.
