BMI Calculator
Calculate Body Mass Index with WHO category and ideal weight.
About BMI Calculator
ToolsOfIndia built the BMI Calculator for health-conscious adults and gym-goers who want straight answers in plain language. Every default assumes Indian conditions, from metric units to INR prices, so the output is usable the moment you read it. Compute Body Mass Index by entering height and weight in metric or imperial units, and the tool returns the BMI value along with the WHO category - underweight, normal, overweight or obese - and the ideal weight range for your height. The category boundaries are 18.5 for underweight and 24.9 for normal, with separate guidance that BMI is a rough guide that ignores muscle mass and body composition. The Indian context matters, because South Asians face diabetes risk at a lower BMI, so the tool also flags the Asian cutoff of 23 for overweight. A height slider and weight input make it quick on a phone, and the ideal range gives a target to work towards. Typical moments to reach for it: checking BMI before a fitness plan, tracking weight loss progress, or screening for underweight or obesity. Bookmark it once and it is ready whenever the need comes up again.

Frequently Asked Questions
What is a healthy BMI range?
A healthy BMI range is 18.5 to 24.9 for adults. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese. BMI ranges are the same for Indian and international populations.
How accurate is BMI?
BMI is a useful screening tool but doesn't distinguish between muscle and fat. Athletes may have high BMI but low body fat. Use body fat percentage for a more accurate health assessment.
What is the ideal weight for my height?
Ideal weight range is calculated from healthy BMI. For 170cm height: healthy weight is 53-72 kg. Our calculator provides your personalized ideal weight range.
What is a healthy BMI?
For most adults, 18.5 to 24.9 is normal, but for South Asians the risk of diabetes rises above 23, so an Asian-specific cutoff is also shown.
Is BMI accurate for muscular people?
No, BMI ignores muscle, so a well-built athlete may show as overweight despite low body fat; combine it with body-fat measurement for such cases.
