Is 107 Kilos a Healthy Weight?
107 kilos (approximately 16 stone 12 pounds) is a significant weight that may or may not be healthy — it entirely depends on your height. For someone who is 5ft 10in (178cm), 107kg would fall into the overweight category. However, for someone taller, such as 6ft 3in (190cm), it could be within a healthy range. This guide explains how to determine whether 107kg is healthy for you specifically, using NHS guidelines and practical health measurements.

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 by Height
To understand whether 107kg is healthy for you, first calculate your BMI using the free BMI calculator on this page. Here are three real-world examples to illustrate how height dramatically affects whether this weight is healthy:
- 5ft 6in (168cm): At this height, 107kg gives a BMI of 34.5 — classified as obese (Class I). This would typically be considered above a healthy weight range.
- 5ft 10in (178cm): At this height, 107kg gives a BMI of 29.8 — classified as overweight but just below the obesity threshold. Still above the healthy range of 18.5–24.9.
- 6ft 2in (188cm): At this height, 107kg gives a BMI of 25.4 — classified as slightly overweight. Very close to the healthy range of 18.5–24.9.
- 6ft 4in (193cm): At this height, 107kg gives a BMI of 24.1 — classified as healthy weight according to NHS guidelines.

NHS Guidance on Healthy Weight and Waist Measurement
According to NHS guidelines, a healthy BMI falls between 18.5 and 24.9. If you weigh 107kg and your BMI is above 25, you're in the overweight or obese category. However, BMI is not the complete picture — waist measurement also matters. The NHS recommends measuring your waist circumference: if you're over 94cm (37 inches) as a man or 80cm (31.5 inches) as a woman, this indicates increased health risk regardless of BMI alone.
If 107kg puts you above a healthy weight range, the good news is that even a 5–10% reduction in body weight can improve blood pressure, blood sugar control, and reduce disease risk. Speak to your GP about healthy weight management options, including structured diet and exercise programmes or, where appropriate, prescription weight loss support.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is 107kg in stones and pounds?
107kg converts to 16 stone 12 pounds (or 16.9 stones). You can use the weight converter tool on this page to convert between kilograms, stone, and pounds instantly. Having a quick reference tool saves time and ensures accuracy when comparing your weight in different measurement systems.
Is 107kg overweight or obese?
Whether 107kg is overweight or obese depends entirely on your height. Use the BMI calculator above to find your personal BMI. If it falls between 25–29.9, you're classed as overweight; 30–34.9 is obese (Class I). Always calculate your individual BMI rather than relying on weight alone.
What is a healthy weight for my height?
The NHS healthy weight range varies by height. A healthy BMI is 18.5–24.9. For example, at 5ft 10in, a healthy weight range is roughly 54–76kg (8st 6lbs to 11st 13lbs). Taller people will have higher healthy weight ranges. Calculate your specific range using our free BMI calculator above.
What should I do if 107kg is above my healthy weight range?
If you're above a healthy weight, start by speaking to your GP. Even losing 5–10% of your body weight improves health outcomes. Your GP can discuss lifestyle changes, structured weight management programmes available through the NHS, and — if appropriate — prescription weight loss options alongside diet and exercise.
Does waist measurement matter if my BMI is high?
Yes. The NHS advises measuring your waist circumference because where fat is stored matters for health risk. Men with a waist over 94cm (37in) and women over 80cm (31.5in) face increased health risk. Waist measurement combined with BMI gives a more complete picture of your health risk than BMI alone.
