What's a Normal Weight For A 5'9 Male?
For a male who is 5'9 (175 cm), the NHS healthy weight range is approximately 62–84 kg (9 stone 10 lbs to 13 stone 2 lbs). This range is based on a healthy BMI of 18.5 to 24.9, which accounts for both health and body composition. However, ideal body weight varies depending on muscle mass, frame size, and individual health factors. Use our free BMI calculator above to find your personal healthy weight range, and our weight converter to switch between kg and stone measurements instantly.

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 For 5'9 Males — NHS Data
The healthy weight range for a 5'9 male is 62–84 kg, which converts to approximately 9 stone 10 lbs to 13 stone 2 lbs in UK measurements. This calculation is based on NHS BMI guidelines, which define a healthy BMI as 18.5 to 24.9.
- At 5'9 (175 cm), a BMI of 18.5 = 56.5 kg (8 stone 13 lbs) — lower end of healthy
- At 5'9, a BMI of 24.9 = 75.3 kg (11 stone 12 lbs) — upper end of healthy
- A BMI of 25.0 to 29.9 is classified as overweight — not yet obese
- A BMI of 30.0 and above is classified as obese
The average UK male is approximately 5'9 (175 cm) and weighs around 85.7 kg (13 stone 7 lbs), which gives an average BMI of approximately 27.9 — in the overweight category. This means many UK males weigh above the healthy range, though individual circumstances vary widely.

Factors That Affect Ideal Weight For Your Height
Ideal weight isn't one-size-fits-all. Several factors influence what a healthy weight means for you personally:
- Muscle mass: Muscle is denser than fat. Athletes and very active males may have a higher weight at the same height while maintaining low body fat — BMI doesn't distinguish muscle from fat
- Frame size: Larger-framed males naturally carry more weight than smaller-framed males at the same height
- Age: Metabolism changes with age; older adults may need different weight targets
- Ethnicity: The NHS recommends lower BMI thresholds for South Asian, Chinese, Black African, and Black Caribbean males — starting at 23.0 instead of 25.0
Your GP can give you personalised advice on what a healthy weight for a 5'9 male means specifically for you, based on your health history and individual circumstances.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is the ideal weight for a 5'9 male in kilograms?
The ideal weight range is approximately 62–84 kg based on NHS healthy BMI guidelines (18.5–24.9). The midpoint of this healthy weight range is around 73 kg (11 stone 5 lbs). However, ideal weight varies by frame size and muscle mass, so this is a reference range, not a precise target.
What weight for height is considered overweight for a 5'9 male?
For a male who is 5'9, a weight above 84 kg (13 stone 2 lbs) starts to enter the overweight BMI category (25.0–29.9). Above approximately 102 kg (16 stone 1 lb), the weight is classified as obese (BMI 30+). Use our BMI calculator to check your personal BMI.
What's the average weight of a UK male at 5'9?
The average UK adult male is approximately 5'9 tall and weighs around 85.7 kg (13 stone 7 lbs), giving an average BMI of about 27.9 — in the overweight range. However, average weight does not equal healthy weight; the NHS healthy weight range for 5'9 is 62–84 kg.
Does being 5'9 and 80 kg mean I'm overweight?
At 5'9 and 80 kg, your BMI is approximately 26.5, which falls into the overweight category (25.0–29.9) according to NHS guidelines. However, if you have significant muscle mass, your body composition may be healthy despite the BMI classification. Your GP can assess your individual health.
How do I calculate my healthy weight range for 5'9?
For 5'9 (175 cm), multiply your height in metres squared by 18.5 (lower healthy BMI) and 24.9 (upper healthy BMI). Lower bound: 18.5 × 1.75² = 56.6 kg. Upper bound: 24.9 × 1.75² = 76.2 kg. Use our free weight loss calculator and healthy weight calculator above for gradual improvement.
