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 Ranges at Different Heights
At 68.4kg, your healthy weight status depends on your height. Using the standard kg to stone conversion, this weight equals 10 stone 10.6 pounds. According to NHS guidelines, a healthy BMI is between 18.5 and 24.9 for most UK adults.
- At 160cm (5ft 3in): 68.4kg gives a BMI of 26.7 — this falls in the overweight range (25.0–29.9). A healthy weight at this height would be 47–63kg (7st 5lb to 9st 13lb).
- At 170cm (5ft 7in): 68.4kg gives a BMI of 23.6 — this is in the healthy weight range. This height supports weights between 54–72kg (8st 6lb to 11st 4lb).
- At 180cm (5ft 11in): 68.4kg gives a BMI of 21.1 — also healthy. At this height, the healthy range is 60–80kg (9st 6lb to 12st 8lb).

NHS Guidance and Next Steps
The NHS recommends that healthy weight is just one part of overall health. Even if 68.4kg is within the healthy BMI range for your height, waist measurement also matters. For men, a waist over 94cm (37 inches) increases health risk; for women, over 80cm (31.5 inches) increases risk. If your weight is outside the healthy range, small changes like a 500 kcal daily deficit can result in sustainable loss of around 0.5kg per week. Speak to your GP if you have concerns about your weight or health — they can provide personalised advice based on your individual circumstances.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is 68.4kg in stone and pounds?
68.4 kilograms equals 10 stone and 10.6 pounds. To convert kilograms to stone, divide by 6.35029. This weight is healthy for taller adults (around 170cm+) but may be overweight for shorter individuals — your height determines whether it falls in the healthy BMI range.
Is 68.4kg a healthy weight?
It depends on your height. At 170cm (5ft 7in), 68.4kg is healthy (BMI 23.6). At 160cm (5ft 3in), it would be overweight (BMI 26.7). Use our free BMI calculator above to check your specific BMI by entering your height and this weight.
What is the healthy weight range for my height?
Healthy weight ranges vary by height. For example, at 165cm the healthy range is 50–66kg (7st 12lb to 10st 5lb). At 175cm it's 57–75kg (8st 13lb to 11st 11lb). Use our BMI calculator to calculate the exact healthy range for your individual height.
How can I lose weight safely if I'm above the healthy range?
The NHS recommends losing 0.5–1kg per week through a combination of reduced-calorie eating and increased physical activity. This typically requires a deficit of around 500 calories daily. Your GP can recommend local weight management support or programmes available on the NHS.
Why does height matter so much for healthy weight?
BMI uses both weight and height in its calculation because taller people naturally carry more weight healthily. A person 180cm tall can weigh more than someone 160cm tall while both remaining in the healthy BMI range. This is why the same weight (68.4kg) can be healthy or overweight depending on your specific height.
