Is 107kg a Healthy Weight? Converting to Stone and Pounds
107 kilograms is equivalent to 16 stone 12 pounds (or approximately 235.9 lbs). Whether this weight is healthy depends entirely on your height, age, and overall health profile. Using the standard kg to stone conversion method (divide by 6.35), we can see that 107kg places most adults into the overweight or obese category according to NHS guidelines — but this varies significantly based on individual height and body composition. Use our free BMI calculator above to check where you stand, and read on to understand what this weight means for your health at different heights.

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 107kg, whether you're at a healthy weight depends on your height. Here are three concrete examples using NHS BMI guidelines:
- 5ft 6in (168cm): 107kg gives a BMI of 34.5 — this falls into the obese (Class I) category. Healthy weight range at this height is 53–71kg (8st 5lbs to 11st 3lbs).
- 5ft 10in (178cm): 107kg gives a BMI of 30.8 — this is obese (Class I). Healthy range is 60–81kg (9st 6lbs to 12st 9lbs).
- 6ft 2in (188cm): 107kg gives a BMI of 27.9 — this is overweight but not obese. Healthy range is 68–92kg (10st 10lbs to 14st 6lbs).
These calculations show why height matters so much when converting kilograms to stone and assessing whether a weight is healthy for you personally. Taller individuals can carry 107kg in a healthier BMI range, while shorter individuals would need to aim lower.

NHS Guidance: What to Do If You're Above a Healthy Weight
If 107kg places you above your healthy weight range, the NHS recommends a gradual, sustainable approach. A safe rate of weight loss is 0.5 to 1kg per week — this means working towards a calorie deficit of around 500 calories per day alongside increased physical activity. Beyond BMI, also measure your waist circumference: men should aim for under 94cm (37in), women under 80cm (31.5in). Even losing just 5–10% of your body weight — about 5–11kg from 107kg — can improve blood pressure, blood sugar control, and reduce health risks significantly. Track your progress with our free progress tracker, and speak to your GP if you'd like support with sustainable weight loss strategies.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is 107kg in stone and pounds?
107 kilograms equals 16 stone 12 pounds (or 235.9 lbs). To convert kilograms to stone, divide by 6.35; to convert to pounds, multiply by 2.20462. The metric to imperial weight conversion is straightforward once you know the standard conversion factors.
Is 107kg overweight or obese?
At 107kg, your category depends on height. Using the metric to imperial weight assessment, this typically falls into the overweight or obese category for adults under 6ft, but may be overweight or even borderline for taller individuals. Use our BMI calculator to check your personal BMI.
What's the healthy weight range for my height?
Healthy weight ranges vary by height. For example, at 5ft 8in, the healthy range is 54–73kg (8st 7lbs to 11st 7lbs). At 6ft, it's 61–82kg (9st 8lbs to 12st 13lbs). Our free BMI calculator will show you your target range instantly based on your exact measurements.
How much weight should I aim to lose from 107kg?
Rather than a fixed target, the NHS recommends losing 5–10% of your body weight initially — for you, that's 5–11kg. This achieves meaningful health improvements. After that, work with your GP on further goals. Sustainable loss is 0.5–1kg per week.
Should I see my GP about my weight?
Yes, if 107kg is above a healthy range for your height, your GP can offer personalised advice, check for weight-related health conditions, and discuss weight management support including lifestyle changes or, if appropriate, referral to specialist services.
