What's a Healthy Weight for a 5ft 5 Female?
If you're 5ft 5 (165cm) and female, your healthy weight range according to NHS guidance is approximately 50–67 kg (7st 12lbs to 10st 7lbs). This range is based on a BMI of 18.5 to 24.9, which is the UK standard for healthy weight. However, your ideal weight depends on your individual build, muscle mass, and overall health. Use our free BMI calculator above to check where you personally fall, and remember that weight management is about improving your health, not achieving a specific number on the scales.

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.
NHS Healthy Weight Range for 5ft 5 Females
At 5ft 5 (165cm), the healthy weight range is approximately 50–67 kg (7st 12lbs to 10st 7lbs) based on NHS BMI guidelines. This is calculated using the standard BMI formula: weight (kg) ÷ height (m)².
- Underweight: Below 50 kg (BMI under 18.5)
- Healthy weight: 50–67 kg (BMI 18.5–24.9)
- Overweight: 67–80 kg (BMI 25–29.9)
- Obese: 80 kg and above (BMI 30+)
If you're of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends slightly lower thresholds — you may be at increased health risk at a lower BMI, so discuss this with your GP. Use our free weight converter to see your weight in different units, and our BMI calculator to check your personal BMI instantly.

Why Your Exact Weight Matters Less Than You Think
BMI is a useful screening tool, but it has important limitations. It doesn't distinguish between muscle and fat — so athletes or very muscular individuals may have a higher BMI but still be healthy. Your waist circumference is equally important: for women, a waist measurement above 80cm (31.5in) suggests increased health risk, and above 88cm (34.5in) indicates higher risk.
What matters most is how you feel, your energy levels, and your health markers like blood pressure and blood sugar. If you're concerned about your weight or health, speak to your GP, who can give you personalised guidance based on your individual circumstances and medical history.

Can I use BMI alone to determine if I'm a healthy weight?

What's the best way to reach a healthy weight if I'm above the range?
Sustainable weight loss of 0.5–1 kg per week through balanced diet and physical activity is recommended by the NHS. Your GP can refer you to weight management services or discuss options. If interested in prescription weight loss support, ask your GP about referral to specialist tier 3 services.
