Ask ten people what a healthy weight is and you will get ten different answers, most of them borrowed from a celebrity, a relative, or a chart seen years ago. The honest answer is less dramatic: healthy weight is a range, not a single number, and that range depends mainly on your height. A person who is 190 cm tall can healthily weigh far more than a person who is 150 cm tall, and comparing the two directly tells you nothing. That is why doctors use body mass index, or BMI, which adjusts weight for height, and why this article works from the cut-offs used in India rather than the global ones you will find on many foreign websites. Used properly, the table below gives you a sensible starting point. Used carelessly, it can mislead you — so the caveats at the end matter as much as the numbers themselves.
Quick answer: Under the Asian Indian cut-offs, a healthy BMI is 18.5 to 22.9. At 165 cm that means roughly 50.4 to 62.3 kg; at 170 cm, 53.5 to 66.2 kg; and at 175 cm, 56.7 to 70.1 kg. Check your own figure with our BMI Calculator, then read the caveats before acting on it.
1. How BMI Is Calculated
BMI is your weight in kilograms divided by your height in metres squared. That sounds technical, but the idea is simple: taller people are expected to weigh more, and squaring the height keeps the comparison fair across heights. Take a person weighing 70 kg at 1.70 metres. Square the height — 1.70 times 1.70 is 2.89 — then divide 70 by 2.89, which gives 24.2. That single number can then be compared against the cut-offs, whatever the person's height. The formula has an obvious weakness, which we will come to: it knows your height and weight and nothing else. It cannot tell whether those kilograms are muscle, fat, bone, or water, and it cannot tell where fat sits on your body. Those limits do not make BMI useless — it remains the standard screening tool worldwide precisely because it is simple, cheap, and roughly right for most people — but they do mean it should be treated as a screening result, not a final verdict.
2. Why India Uses Lower Cut-Offs
Most international charts call a BMI below 25 normal and 30 or above obese. In India, clinicians commonly use lower Asian Indian thresholds: 18.5 to 22.9 is normal, 23 to 24.9 is overweight, and 25 and above is obese. The reason is not that the maths changes; it is that the risk changes. Research over the past two decades has consistently found that South Asian populations tend to carry a higher proportion of body fat at a given BMI, and to develop type 2 diabetes and heart disease at lower BMIs than European populations. A BMI of 24, comfortably normal on a global chart, already sits in the overweight band on the Indian scale, and that earlier warning is the point: it prompts a conversation about diet, activity, and blood sugar before problems become entrenched. If you have only ever seen the global chart, the Indian table can come as a surprise, and some people will find themselves reclassified. That reclassification is a prompt to check other markers — waist size, blood pressure, blood sugar — not a reason to panic or to crash-diet.
3. The Healthy Weight Table by Height
The table below converts the Indian normal range of 18.5 to 22.9 into kilograms for heights from 150 cm to 190 cm. Each row is a range, and any weight inside the range falls in the normal band for that height. The overweight threshold, BMI 23, is shown so you can see how close the boundary sits: at most heights it is less than a kilogram above the top of the normal range, which is why small, steady weight changes matter more than dramatic ones. Read your row, note where you currently sit, and remember that the table describes adults. Children need a different scale entirely, as explained in the questions below.
| Height | Healthy weight (BMI 18.5–22.9) | Overweight from (BMI 23) |
|---|---|---|
| 150 cm | 41.6 – 51.5 kg | 51.8 kg |
| 155 cm | 44.4 – 55.0 kg | 55.3 kg |
| 160 cm | 47.4 – 58.6 kg | 58.9 kg |
| 165 cm | 50.4 – 62.3 kg | 62.6 kg |
| 170 cm | 53.5 – 66.2 kg | 66.5 kg |
| 175 cm | 56.7 – 70.1 kg | 70.4 kg |
| 180 cm | 59.9 – 74.2 kg | 74.5 kg |
| 185 cm | 63.3 – 78.4 kg | 78.7 kg |
| 190 cm | 66.8 – 82.7 kg | 83.0 kg |
Two examples make the table concrete. A person 165 cm tall weighing 60 kg has a BMI of 22.0, inside the normal range. The same person at 70 kg would have a BMI of 25.7, in the obese band on Indian cut-offs, even though 70 kg sounds unremarkable on its own. Conversely, a person 175 cm tall weighing 95 kg has a BMI of 31.0, well into the obese range, and the distance back to the top of the normal range — 70.1 kg — shows why sustainable, gradual loss beats any short crash programme. Notice also how wide each range is: at 170 cm the normal band spans nearly 13 kg. That width is a feature, not a flaw. It reflects real differences in frame, muscle, and build, and it means you do not need to chase one exact number.
4. What BMI Gets Wrong
BMI fails in predictable directions, and knowing them stops a good tool from becoming a bad judge. Athletes and people who lift weights regularly can score as overweight while carrying very little fat, because muscle is dense and heavy. Older adults can score as normal while carrying excess fat, because muscle loss with age lowers weight even as fat rises. Pregnant women, people with fluid retention, and those with unusual builds all fall outside what the formula assumes. Fat distribution matters too: fat carried around the waist is more closely linked to heart and metabolic risk than fat carried on the hips and thighs, and BMI says nothing about either. That is why a waist measurement is a useful second check. As a rough guide used by many clinicians, a waist above 90 cm for Indian men and above 80 cm for Indian women signals increased risk even when BMI looks acceptable, and it is worth discussing with a doctor rather than treating as a verdict on its own.
5. Using the Number Sensibly
Start by finding your BMI honestly: weigh yourself in the morning, in light clothing, on a level floor, and measure your height without shoes, standing straight. Enter both figures in the calculator and note the band, not just the decimal. Then look at the trend rather than a single reading. Weight moves daily with meals, water, and clothing, so weighing once a month, at the same time and on the same scale, gives a far clearer picture than daily weighing. If your BMI sits in the normal range and your waist, blood pressure, and energy are fine, there is nothing the table asks you to fix. If it sits above 23, treat that as a reason to look at everyday habits — portion sizes, sugary drinks, fried snacks, walking and sleep — before reaching for any supplement or extreme diet. And if it sits below 18.5, consider whether you are eating enough and whether an underlying health issue deserves a check-up, since being underweight carries its own risks. In both directions, a doctor's view beats a chart's: BMI screens, a clinician diagnoses.
6. A Realistic Next Step
The most useful thing about a height-weight table is that it turns a vague worry into a concrete, modest target. If you are 170 cm and 85 kg, with a BMI of 29.4, the goal is not to reach 53.5 kg — the bottom of the range — but to move steadily toward 66.2 kg, the top of it, and then reassess. A loss of even 5 to 10 percent of body weight improves blood sugar, blood pressure, and joint load measurably, and it is far more achievable than a transformation promised in thirty days. Pair that with walking, strength work twice a week, and a diet built on regular home food rather than packaged fixes, and recheck in three months. The table will still be there, unchanged. What changes is where you sit in it, and that slow movement is exactly what healthy weight management looks like.
