BMI for Men at 160 cm — Healthy Weight 47.4–63.7 kg
At 160 cm, the healthy weight range for a man is 47.4 kg to 63.7 kg. That range comes from the WHO BMI categories (18.5–24.9), and this page shows the full working: the formula, a table of BMI values across weights at this height, and what to do with the result — including the situations where BMI is least reliable.
The headline figures are simple: at 160 cm, a BMI of 18.5 corresponds to 47.4 kg and a BMI of 24.9 corresponds to 63.7 kg. Everything between those two weights is the WHO healthy range; below it is underweight, from 25.0 to 29.9 is overweight, and 30 and above is obese. As a concrete example, a man at 160 cm weighing 80 kg has a BMI of 31.2 (Obese).
Remember what this page is: an estimate from a screening tool, not medical advice and not a diagnosis. BMI was designed for population studies, and it works best when it is read alongside other measures — waist circumference, body-fat percentage, blood pressure and how active you are. The sections below give you those next steps.
Calculate your own BMI
Use the BMI calculator to work out your own BMI at any height and weight. Enter your measurements and the tool applies the same formula shown below, with your WHO category. If you also want an estimate of body fat, try the body fat calculator.

The formula, shown and cited
BMI is defined by the World Health Organization as weight in kilograms divided by height in metres squared:
BMI = weight (kg) ÷ height (m)²
Worked through for this page, using 80 kg as the example weight:
- Height: 160 cm = 1.60 m (5 ft 3.0 in)
- Height squared: 1.60 × 1.60 = 2.5600 m²
- Weight: 80 kg (176.4 lb)
- Calculation: 80 ÷ 2.5600 = 31.2
The WHO categories are: underweight below 18.5, healthy weight 18.5–24.9, overweight 25.0–29.9, and obese 30 and above. At 31.2, this example is Obese. The same formula applies to every adult; the categories are the same for men and for the other sex, though the interpretation can differ with age, muscle mass and ethnicity, which is one more reason to treat the number as a starting point rather than a verdict.
The healthy weight range at 160 cm
| Boundary | BMI | Weight |
|---|---|---|
| Bottom of healthy range | 18.5 | 47.4 kg (104.4 lb) |
| Top of healthy range | 24.9 | 63.7 kg (140.5 lb) |
| Range width | — | 16.4 kg |
The range is derived directly from the formula: the bottom is 18.5 × 2.5600 = 47.4 kg, and the top is 24.9 × 2.5600 = 63.7 kg. It is a guide, not a target you must hit exactly; many healthy people sit near its edges. What matters more than the exact kilogram is the direction of travel and the other measures — waist, body fat, fitness — that sit alongside it.
BMI at 160 cm across weights
| Weight | BMI | Category |
|---|---|---|
| 40 kg | 15.6 | Underweight |
| 50 kg | 19.5 | Healthy Weight |
| 60 kg | 23.4 | Healthy Weight |
| 70 kg | 27.3 | Overweight |
| 80 kg | 31.2 | Obese |
| 90 kg | 35.2 | Obese |
| 100 kg | 39.1 | Obese |
| 110 kg | 43.0 | Obese |
| 120 kg | 46.9 | Obese |
This table shows how sensitive BMI is to weight at a fixed height: every 10 kg moves the BMI by about 3.9 points at 160 cm. Read across to find your own weight, then read the category — and then read the rest of this page before deciding what, if anything, to do about it.
Where the category boundaries fall at 160 cm
| Threshold | Weight at 160 cm |
|---|---|
| BMI 18.5 | 47.4 kg |
| BMI 25.0 | 64.0 kg |
| BMI 30.0 | 76.8 kg |
| BMI 35.0 | 89.6 kg |
| BMI 40.0 | 102.4 kg |
These thresholds are the same BMI values used everywhere — 18.5, 25, 30, 35 and 40 — translated into kilograms at this height. They show how far apart the categories are in weight terms: at 160 cm, the gap between the bottom of the healthy range and the obese threshold is 29.4 kg. That spread is why small, sustained changes matter more than dramatic ones.
What the number means for men
For men, the sharpest limit of BMI is muscle: a man who trains regularly can carry a BMI of 27 or 28 with a body-fat percentage in the athletic range, because muscle is denser than fat. That does not make the number meaningless — at a population level it still tracks risk — but it does mean a man in the overweight range who lifts weights should check waist circumference (a commonly used flag is above 94 cm for men) and a body-fat estimate before concluding anything about his health. BMI is also less reliable in older men, where muscle loss can keep the BMI in the healthy range while body fat rises.
What the number does NOT tell you
A single BMI reading has no memory: it cannot tell you whether weight was gained or lost recently, whether the change was muscle or fat, or how long the current weight has been held. It also says nothing about habits — diet quality, sleep, activity, smoking — that shape health far more directly than a ratio does. Use 31.2 as a prompt to gather the other measures, not as a final word on health.
BMI does not measure fitness, blood pressure, blood sugar or cholesterol, and it is less reliable for older adults (who may have lost muscle), for very tall or short people, and for some ethnic groups. None of this makes BMI useless — it makes it a first step. If your BMI is outside the healthy range, the right response is to gather the other measures and talk to a healthcare professional, not to panic or to crash-diet.
How to use the result
Use the healthy range on this page as a zone, not a finish line. Many healthy people sit near its edges, and the first meaningful goal is often a 5–10% change in body weight, which brings measurable health benefits well before the top of the range is reached. Pair any weight change with strength training, which protects muscle while fat is lost.
If your BMI is in the overweight or obese range, or you have other health concerns such as diabetes, high blood pressure or joint pain, involve a healthcare professional before starting a weight-loss plan — they can check the things BMI cannot see. And if your BMI is underweight, the same advice applies in the other direction: a healthcare professional can check for underlying causes before any plan to gain weight.
Frequently asked questions
What is the healthy weight for a man at 160 cm?
Between 47.4 kg and 63.7 kg — the weights that give a BMI of 18.5 and 24.9 at 160 cm. That is the WHO healthy range. It is a guide, not a prescription: many healthy men sit near its edges, and waist measurement and body fat matter as much as the kilogram figure.
What is the BMI of a man at 160 cm and 80 kg?
31.2 (Obese). The calculation is 80 ÷ (1.60 × 1.60) = 80 ÷ 2.5600 = 31.2. The formula is the same for every adult; only the numbers change.
Is BMI calculated differently for men?
No — the formula is identical for men and men: weight in kilograms divided by height in metres squared, with the same WHO categories. What differs is interpretation: men on average carry more body fat at the same BMI, so the same number can mean a different body composition. That is why waist circumference and body-fat estimates are the essential companions to BMI.
Can BMI be wrong for muscular men?
Yes — this is BMI's best-known limit. Muscle is denser than fat, so a muscular person can have a BMI in the overweight or obese range with very little body fat. That is why the WHO describes BMI as a screening tool: it flags people to look at more closely, and the follow-up should include waist circumference and, where useful, a body-fat estimate.
Should I try to change my BMI quickly?
No. Aim for a gradual change of 0.5–1% of body weight per week, through sustainable eating and activity changes. Very fast weight loss usually means lost muscle as well as fat, and very-low-calorie diets carry real risks. Keep daily intake above 1,200 kcal (women) or 1,500 kcal (men) and talk to a healthcare professional before any major change.
Estimates only, not medical advice. Minimum safe intakes: 1,200 kcal/day women, 1,500 kcal/day men — consult a healthcare professional before a very-low-calorie diet.
