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.

88.3kg BMI & Healthy Weight Context
At 88.3kg, your BMI depends on your height. For example, at the average UK adult height of 175cm (5ft 9in), 88.3kg gives a BMI of approximately 28.8 — which falls into the overweight category according to NHS guidelines. At 170cm (5ft 7in), the BMI would be around 30.5, which is in the obese category. Use our free BMI calculator above to check your personal BMI and healthy weight range based on your actual height. Even a modest weight loss of 5–10% can bring meaningful health benefits including improved blood pressure and blood sugar control.
