Frequently Asked Questions

Q: What is a healthy BMI?
A: For adults, a BMI of 18.5 to 24.9 is considered healthy. Below 18.5 is underweight, 25-29.9 is overweight, and 30 or above is classified as obese.
Q: Is BMI accurate for everyone?
A: BMI is a useful screening tool but has limitations. It may overestimate fat in muscular people (like athletes) and underestimate fat in older adults who have lost muscle mass.
Q: Is BMI different for Asians?
A: Yes. Health organisations recommend lower BMI cutoffs for South Asians. Overweight is classified at BMI ≥23 and obese at ≥27.5 for Asian populations.
Q: Can children use this calculator?
A: This calculator is designed for adults. Children's BMI is assessed differently using age- and gender-specific growth charts. Consult your paediatrician for children's weight assessment.
💡 Pro Tip: BMI is a starting point, not the complete picture. Waist circumference is equally important — for Indians, a waist above 90cm (men) or 80cm (women) indicates increased health risk regardless of BMI.
