Body Mass Index (BMI) is the quickest way to check whether your weight is in a healthy range for your height — used by doctors, insurers, and fitness apps worldwide. Whether you track wellness in kg and cm or prefer feet-inches and pounds, Pitara's free BMI calculator gives instant results with WHO category labels, privately in your browser.
Why calculate BMI in the browser?
Health data should stay on your device. Pitara's BMI Calculator never uploads your height or weight — ideal when checking privately before a doctor visit or insurance medical. No app install, no account, and works on any phone or laptop in India with a modern browser.
BMI is a screening tool, not a diagnosis. It helps flag underweight, normal, overweight, or obese ranges so you know when to consult a physician — especially relevant given rising lifestyle-related conditions in urban India.
Step-by-step: check your BMI
- Open the BMI Calculator.
- Choose metric (kg / cm) or imperial (lb / ft-in) units.
- Enter your current height and weight.
- View your BMI value and category: underweight, normal, overweight, or obese.
Understanding BMI categories (WHO)
- Below 18.5 — Underweight
- 18.5 to 24.9 — Normal (healthy range for most adults)
- 25.0 to 29.9 — Overweight
- 30.0 and above — Obese
Indian populations may face elevated health risks at lower BMI thresholds than Western charts (some clinicians reference lower cutoffs for overweight). Use BMI as one signal alongside waist circumference, blood pressure, and blood sugar — especially if you have a family history of diabetes or heart disease.
Tips and use cases
- Measure weight in the morning before eating for consistency.
- Stand straight against a wall for height — shoes off.
- Athletes with high muscle mass may read "overweight" despite low body fat.
- Pregnancy, elderly adults, and children need specialized charts — standard BMI is for adults.
- Track monthly alongside diet changes rather than obsessing over daily swings.
