Height to Weight Graph — Find Your Healthy Weight Range
A height to weight graph is a practical visual tool that shows the healthy weight range for adults based on their height, aligned with NHS guidance. Rather than a single "ideal" weight, these graphs display a range—because healthy weight varies based on age, muscle mass, bone density, and individual health factors. Using our free BMI calculator alongside a height to weight reference helps you understand whether your current weight falls within NHS-recommended healthy ranges for UK adults.

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.
UK Height and Weight Guidelines — What NHS Recommends
The NHS uses BMI (Body Mass Index) as the primary screening tool to assess whether weight is healthy for a given height. A healthy BMI ranges from 18.5 to 24.9, which translates into different weight ranges depending on your height.
- At 5ft 4in (163cm): healthy weight is approximately 47–63kg (7st 5lbs to 9st 13lbs)
- At 5ft 8in (173cm): healthy weight is approximately 55–75kg (8st 8lbs to 11st 10lbs)
- At 5ft 10in (178cm): healthy weight is approximately 59–80kg (9st 3lbs to 12st 8lbs)
- At 6ft 0in (183cm): healthy weight is approximately 64–87kg (10st 1lbs to 13st 9lbs)
For adults of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends lower BMI thresholds: 18.5 to 22.9 is considered healthy, reflecting higher cardiovascular risk at standard BMI ranges. Our weight converter and BMI calculator make it easy to check your personal targets using UK measurements.

Why a Graph Matters — Understanding Weight Management in Context
Height to weight graphs provide important context that a single number cannot. They show that healthy weight is a range, not a fixed target. Two people of the same height and weight may have completely different body compositions—one athletic with significant muscle, another with higher body fat. This is why BMI has limitations: it does not distinguish between muscle and fat. The NHS advises considering both BMI and waist circumference (over 94cm for men or 80cm for women signals increased health risk) for a complete picture. Your GP can provide personalised health guidance beyond what any graph shows, especially if you have weight-related health conditions or are taking weight management medication.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is the healthy weight for my height in UK measurements?
Use the BMI calculator on this page to find your healthy weight range instantly. Enter your height in feet and inches (or cm) and the calculator displays your target range in stone and pounds or kilograms, based on NHS guidelines. Individual ranges vary, so speak to your GP for personalised advice.
Is there a difference between healthy weight ranges for men and women?
No—BMI and healthy weight ranges are the same for men and women of the same height. However, body composition differs: women typically have higher essential body fat levels (10–13%) than men (2–5%), but BMI calculations remain equal. Your GP can discuss body composition if relevant to your health.
Why do height to weight charts sometimes show different ranges?
Different charts may use slightly different BMI thresholds or rounding. The NHS standard is BMI 18.5–24.9 for healthy weight. Lower thresholds (18.5–22.9) apply to South Asian, Chinese, Black African, and Black Caribbean adults due to higher metabolic health risks at standard BMI levels.
Should I aim for the bottom or top of the healthy weight range?
Neither—aim for the middle or wherever you feel healthy and sustainable. The range exists because different people of the same height have different frame sizes, muscle mass, and health needs. Your GP can help identify the best target weight for your individual circumstances.
Can I use a height to weight graph if I'm trying to lose weight with medication?
Yes. If you're using weight loss medication like Mounjaro or Wegovy, use the healthy weight range as your long-term target. Our GLP-1 weight loss calculator can help estimate potential results, and our progress tracker lets you monitor your journey toward your NHS-recommended healthy range.
