Average Weight For A 5'5 Female In Kg
The average weight for a 5'5 female (165 cm) in the UK is approximately 70 kg (11 stone). However, average does not mean ideal — your healthy weight range depends on your individual BMI and health profile. According to NHS guidelines, a healthy weight for someone 5'5 tall falls between roughly 50 kg and 68 kg (7 stone 12 lbs to 10 stone 10 lbs), based on a healthy BMI of 18.5 to 24.9. This guide explains where you fit and how to use the BMI framework to find your personal healthy weight range.

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 5'5 Females — BMI Based
For a woman who is 5'5 tall (165 cm), the healthy weight range using NHS BMI guidelines is approximately 50 kg to 68 kg (7 stone 12 lbs to 10 stone 10 lbs). This range corresponds to a BMI of 18.5 to 24.9, which the NHS classifies as healthy weight.
Here's the breakdown:
- BMI 18.5 (lower healthy bound): approximately 50 kg (7 stone 12 lbs)
- BMI 24.9 (upper healthy bound): approximately 68 kg (10 stone 10 lbs)
- Overweight threshold (BMI 25): above 68 kg
- Obese threshold (BMI 30): above 82 kg (12 stone 13 lbs)
The average UK female weight of around 70 kg falls slightly into the overweight category by BMI standards, though average and healthy are different concepts. Your ideal body weight depends on factors including muscle mass, frame size, age, and overall health — not just height alone.

How To Calculate Your Personal Healthy Weight Using BMI
The best way to determine your personal healthy weight range is to use our free BMI calculator above — it instantly shows where your weight falls on the NHS BMI scale for your height. Simply enter your current weight in kg or stone and lbs, plus your height, and you'll see your BMI category immediately.
If you're outside the healthy weight range (18.5–24.9), a realistic goal is to move into that bracket. Remember: weight loss should be gradual (0.5–1 kg per week according to NHS guidance) to be sustainable. You can also use our free weight converter to switch between kg, stone, and pounds as you track progress — and our progress tracker helps you log your journey over time.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What's the difference between average weight and healthy weight?
Average weight is the statistical mean for UK women of a given height — around 70 kg for 5'5 females. Healthy weight is based on BMI ranges (18.5–24.9) and represents weights associated with lower health risks. Average and healthy are not the same; many people weigh more than the average but still fall within a healthy BMI range.
Is 70 kg overweight for a 5'5 female?
At 5'5 tall, 70 kg gives a BMI of approximately 27, which falls in the NHS "overweight" category (BMI 25–29.9). However, this depends on individual factors like muscle mass and frame size. Use the BMI calculator on this page to check your personal classification.
Can I be healthy above the 68 kg upper healthy weight limit?
BMI is a screening tool only and doesn't account for muscle mass, bone density, or distribution of fat. Some people, particularly those with significant muscle, may have a BMI above 24.9 and still be healthy. Your GP can assess your individual health status — BMI is a starting point, not a verdict.
What's a realistic weight loss target if I'm above the healthy range?
NHS guidance recommends losing 0.5–1 kg per week for sustainable results. If you're at 75 kg and aiming for 65 kg (within the healthy range), that's realistic over 10–20 weeks with reduced calories and increased activity. Avoid very gradual weight management — it increases muscle loss.
Should I use the healthy weight for 5'5 females or my ideal body weight?
The healthy weight range (BMI 18.5–24.9) is evidence-based and appropriate for most people. Your "ideal" weight is personal and may sit anywhere within that range. Factors like how you feel, your strength, energy levels, and health markers matter more than hitting an exact number. ```
