107kg in Stones — Healthy Weight Guide for UK Adults
107kg converts to 16 stone 12 pounds — but whether this is a healthy weight for you depends entirely on your height and individual circumstances. The NHS uses Body Mass Index (BMI) to assess whether a weight falls within a healthy range, and 107kg can represent anything from a healthy weight to overweight depending on how tall you are. This guide shows you exactly where 107kg sits for different heights, and what NHS guidance recommends next.

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's how 107kg breaks down across common UK heights:
- At 5ft 4in (163cm): BMI of 31.8 — falls in the obese range. Healthy weight range for this height is 49–66kg (7st 9lbs to 10st 5lbs)
- At 5ft 8in (173cm): BMI of 29.2 — falls in the overweight range. Healthy weight range is 56–75kg (8st 10lbs to 11st 10lbs)
- At 5ft 10in (178cm): BMI of 27.1 — also overweight. Healthy weight range is 58–79kg (9st 1lbs to 12st 5lbs)
- At 6ft (183cm): BMI of 25.4 — falls in the healthy weight range. Healthy range for this height is 61–82kg (9st 8lbs to 12st 13lbs)

NHS Guidance and What to Do Next
According to NHS guidelines, a healthy BMI is between 18.5 and 24.9 for most adults. If 107kg puts you above this range, you're not alone — around 63% of UK adults are overweight or obese. The good news is that even modest weight loss of 5–10% of your body weight can bring real health benefits.
Beyond BMI, the NHS also recommends checking your waist circumference: over 94cm (37in) for men or 80cm (31.5in) for women indicates increased health risk. If you're concerned about your weight, start by talking to your GP, who can assess your individual health picture and discuss options including lifestyle changes, structured weight loss programmes, or—if appropriate—prescription weight management support. Our free weight converter and progress tracker can help you monitor changes over time.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
Is 107kg overweight?
At 107kg, it depends on your height. If you're 5ft 8in or shorter, 107kg is likely in the overweight or obese BMI range. If you're taller (6ft or above), it may fall in the healthy range. Use the BMI calculator on this page to find out where you sit based on your exact height.
What's the healthy weight range for someone 107kg?
There isn't a single healthy weight — it depends on your height, age, sex, and muscle mass. For most adults, the NHS healthy BMI range is 18.5–24.9. Use our free BMI calculator to see the healthy weight range for your specific height, or talk to your GP for personalised guidance.
How do I convert 107kg to stone and pounds?
107kg equals 16 stone 12 pounds (or approximately 16st 12lbs). You can use our free weight converter at the top of this page to convert between kilograms, stones, and pounds instantly.
Can I lose weight safely from 107kg?
Yes. The NHS recommends losing 0.5–1kg per week as a safe, sustainable rate. This typically requires a calorie deficit of around 500 calories per day. Your GP can advise you on realistic goals and support options tailored to your health.
What if 107kg is above the healthy range for my height?
If you're above a healthy weight range, even a 5% reduction in body weight can improve blood pressure, blood sugar, and cholesterol. Start by discussing options with your GP — these include lifestyle changes, structured weight loss programmes, or prescription medication if clinically appropriate.
