Your tests
Adult BMI calculator
BMI is a screening measure of weight relative to height, for adults aged 20 and older. It should be read with other health information.
Your result will appear here. It is a starting point, not a diagnosis.
About the BMI calculator
- What it is for
- A quick screening measure that relates your weight to your height. Doctors use it as one starting point, not as a verdict. [12]
- Who it is for
- Adults aged 20 and older. It is not for children or during pregnancy.
- What it asks, and why
- Your height and your weight. These are the only two numbers the BMI formula uses. You can enter centimetres and kilograms, or feet, inches and pounds.
- What your result means
- A number in kg/m² compared with the WHO public health action points for Asian populations: below 18.5 underweight, 18.5 to 22.9 lower risk, 23.0 to 27.4 increased risk, and 27.5 and above high risk, with further points at 32.5 and 37.5. These points describe risk across groups of people, not your own health. [22]
- What it cannot tell you
- BMI does not measure body fat, tell fat from muscle, or show where fat is carried. It cannot diagnose a condition, and it cannot show whether any treatment or medicine is suitable for you. WHO keeps the international categories (overweight from 25, obesity from 30) for comparing countries, so other reports may use different numbers. [22]
- Practical next step
- Note the result and today’s date. Add a waist measurement if you can, and take both to an appointment with your questions, or request a doctor or nutritionist consultation.
- When to speak with a professional
- If your result is outside the healthy range, or inside it but you are worried about your weight or symptoms. Speak with a qualified healthcare professional if you have symptoms or concerns, whatever the result. Seek urgent care for chest pain, severe breathlessness or fainting.
Diabetes risk check
Uses the Indian Diabetes Risk Score (age, waist, activity, family history), developed for South Asian adults. It cannot diagnose diabetes or prediabetes.
Your result will appear here. It is a starting point, not a diagnosis.
About the diabetes risk check
- What it is for
- A short questionnaire that gives a screening score out of 100. It helps you decide whether to talk to a doctor about blood glucose testing. [11]
- Who it is for
- Adults aged 20 and older who have not been diagnosed with diabetes and are not pregnant. The Indian Diabetes Risk Score was developed and tested in India. [11]
- What it asks, and why
- Four things: your age, waist measurement, how active you are, and whether your parents have diabetes. These are the four items the score is built from. Nothing else is used.
- What your result means
- The score adds up points for each answer. Below 30 is shown as a lower screening score, 30 to 59 as moderate and 60 or more as high. A higher score means more of the questionnaire’s risk factors apply. A score of 30 or more is a prompt to talk to a doctor about blood glucose testing.
- What it cannot tell you
- It cannot diagnose diabetes or prediabetes, and a lower score does not rule them out. In Pakistan, diabetes or prediabetes has been found in people with a normal BMI, especially with a family history. [7] The score does not look at symptoms, medicines or other conditions, and it is not a treatment recommendation or a decision about any medicine.
- Practical next step
- Tell your doctor your score and your family history, and ask which blood test is appropriate and when to repeat it.
- When to speak with a professional
- Thirst, frequent urination, blurred vision, unexplained weight loss or persistent tiredness need attention whatever your score. [14] Speak with a qualified healthcare professional if you have symptoms or concerns, whatever the result. Seek urgent care for chest pain, severe breathlessness or fainting.
Calorie estimate
Estimates daily energy needs to maintain current weight, using the Mifflin-St Jeor equation. It is not a meal plan or a weight-loss target.
Your result will appear here. It is a starting point, not a diagnosis.
About the calorie estimate
- What it is for
- An estimate of the energy your body uses in a day to keep your current weight. It uses the Mifflin-St Jeor equation. [21]
- Who it is for
- Adults aged 20 and older who are not pregnant or breastfeeding. The equation was developed from measurements in healthy adults. [21]
- What it asks, and why
- Age, sex, height and weight, because the equation uses all four. It also asks how active you usually are, which adjusts the estimate for your routine.
- What your result means
- A number of calories (kcal) per day that is an estimate of what keeps your weight steady. Your real needs can be higher or lower.
- What it cannot tell you
- It is not a weight-loss target, a meal plan or medical nutrition advice. It does not account for health conditions, medicines or changes in body composition.
- Practical next step
- Bring the estimate and a note of a typical day of meals to a nutritionist. Do not make large cuts to what you eat because of this number.
- When to speak with a professional
- Before changing what you eat if you have diabetes, kidney disease, food allergies or take regular medicines, or if you are pregnant. [4] Speak with a qualified healthcare professional if you have symptoms or concerns, whatever the result. Seek urgent care for chest pain, severe breathlessness or fainting.
Waist-to-hip ratio
Compares your waist and hip measurements. It does not diagnose a disease or replace a clinical assessment.
Your result will appear here. It is a starting point, not a diagnosis.
About the waist-to-hip ratio
- What it is for
- It compares your waist with your hips to describe where your body carries weight. Weight around the waist can matter for health in addition to total weight. [20]
- Who it is for
- Adults. It is not for children or during pregnancy.
- What it asks, and why
- Your sex, because the WHO reference value differs for men and women, and your waist and hip measurements in the same unit. The ratio is the waist divided by the hip. WHO describes measuring the waist midway between the lowest rib and the top of the hip bone, and the hips at the widest part of the buttocks. Your healthcare professional can show you. [20]
- What your result means
- A ratio such as 0.90. WHO reports that ratios of 0.90 or more in men and 0.85 or more in women are linked with a substantially increased risk of metabolic problems, and notes that suitable cut-off points can differ between populations. The tool shows whether your ratio is at or above the WHO reference value for your sex. It uses the WHO values; no separate Asian value is applied. [20]
- What it cannot tell you
- It cannot diagnose a disease, explain the cause of your weight, or show whether any treatment is suitable. Measurements can vary with technique, so a different measurer may get a different number.
- Practical next step
- Measure twice, note the ratio and the date, and take it to your doctor with your BMI and your questions.
- When to speak with a professional
- If you are unsure how to measure, or want to know what your ratio means for you. Speak with a qualified healthcare professional if you have symptoms or concerns, whatever the result. Seek urgent care for chest pain, severe breathlessness or fainting.
Waist size
Compares your waist measurement with the WHO Asia-Pacific reference points for adults. It does not diagnose a disease or replace a clinical assessment.
Your result will appear here. It is a starting point, not a diagnosis.
About the waist size check
- What it is for
- It compares your waist measurement with the WHO Asia-Pacific reference points, which are used as a marker of central (abdominal) obesity in Asian adults. [23]
- Who it is for
- Adults aged 20 and older. It is not for children or during pregnancy.
- What it asks, and why
- Your sex, because the reference point is 90 cm for men and 80 cm for women, and your waist measurement. Measure midway between the lowest rib and the top of the hip bone, as shown in the waist-to-hip ratio test. [20]
- What your result means
- Whether your waist is below, or at or above, the reference point for your sex. These points describe risk across groups of Asian adults, not your own health. [23]
- What it cannot tell you
- It cannot diagnose a condition, measure body fat directly, or show whether any treatment or medicine is suitable for you. Other guidelines use slightly different points for some Asian countries.
- Practical next step
- Note your measurement and the date, and take it to an appointment together with your BMI.
- When to speak with a professional
- If your waist is at or above the reference point, or you are worried about your health. Speak with a qualified healthcare professional if you have symptoms or concerns, whatever the result. Seek urgent care for chest pain, severe breathlessness or fainting.
Results are estimates or screening information, not a diagnosis, treatment recommendation or eligibility decision for any medicine. The diabetes, calorie, waist-to-hip and waist size tools are working drafts and need CCL medical approval before launch. BMI and waist size use the WHO reference points for Asian populations.
How BMI is read for Asian adults.
WHO public health action points for Asian populations, for adults aged 20 and older, in kg/m². Categories are labelled in words, not colour alone. BMI is one part of assessment. [22]
UnderweightBelow 18.5
Lower risk18.5 to 22.9
Increased risk23.0 to 27.4
High risk27.5 to 32.4
High risk32.5 to 37.4
High risk37.5 or above
WHO keeps the international categories (overweight from 25, obesity from 30) for comparing countries. Your clinician may use either, alongside your waist size and other health information. [22]
Where to measure for waist-to-hip ratio.
Use the same unit for both measurements. The ratio compares waist to hips and does not diagnose a disease. Your healthcare professional can show you the approved way to measure.
Need help interpreting a result?
A number can be useful, but your questions matter too. Talk to a healthcare professional about what your result means for you.
When to speak with a professional.
Speak with a qualified healthcare professional if
- You are worried about your weight or your health, or you want help understanding a result.
- You have thirst, frequent urination, blurred vision, unexplained weight loss or persistent tiredness. These need an assessment whatever a website score says. [14]
- Diabetes runs in your family, or you have a health condition or take regular medicines. Do not stop or change a medicine without speaking to your prescriber.
Seek urgent medical care for
- Chest pain, severe breathlessness or fainting.
- Any severe or sudden symptom that worries you.
- This website and its forms are not emergency services. Go to the nearest hospital or contact local emergency services.
