Your BMI
Where your BMI sits
The marker shows your BMI on the standard scale. It redraws from your inputs.
- The BMI formula is identical for men and women — what differs is how the result is usually interpreted, because men carry more muscle mass on average.
- At the defaults — 5 ft 10 in and 180 lb — BMI is 25.8, just into the overweight band, with a healthy weight range of 128.9–173.5 lb for that height.
- Waist and hip measurements add a waist-to-hip ratio, and for ages 2–19 the result switches to CDC BMI-for-age percentiles.

One clarification before the guide: this is the men’s BMI calculator in the CalcFolk health set — the same tool whether you searched for a BMI calculator for men, a mens BMI calculator or a men BMI calculator. It returns your BMI, your category and the exact healthy weight range for your height. What it cannot do alone is tell muscle from fat, or a 25-year-old’s body from a 65-year-old’s — so the guide below adds the full chart for men, the muscle-mass caveat with the arithmetic shown, and a short account of how the same number should be read at different ages.

The math behind your BMI
Body mass index compares your weight to your height. The formula is identical for men and women — what differs is how the result is usually interpreted, because men carry more muscle mass on average.
Worked examples:
| Man | Calculation | BMI → category |
|---|---|---|
| 5 ft 10 in, 180 lb (81.6 kg, 1.78 m) | 81.6 ÷ 1.78² = 81.6 ÷ 3.1684 | 25.8 → Overweight |
| 5 ft 7 in, 154 lb (70 kg, 1.70 m) | 70 ÷ 1.70² = 70 ÷ 2.89 | 24.2 → Normal weight |
| 6 ft 3 in, 265 lb (120 kg, 1.90 m) | 120 ÷ 1.90² = 120 ÷ 3.61 | 33.2 → Obese |
| 5 ft 10 in — healthy range | 18.5 × 3.1613 and 24.9 × 3.1613 | 128.9 – 173.5 lb |

The categories — and why BMI needs a second look for men.
The World Health Organization categories below apply to adult men and women alike:
| BMI | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal weight |
| 25.0 – 29.9 | Overweight |
| 30.0 and above | Obese |
These are screening bands for populations. Where you fall is a starting point for a conversation about health — not the whole story.
BMI cannot tell muscle from fat — it only sees total weight. That matters more for men, who tend to carry more lean mass:
- The athlete problem: a rugby player or lifter at 6 ft and 220 lb of mostly muscle scores a BMI near 30 — “obese” — with low actual body fat.
- The skinny-fat problem: the reverse also happens — a “normal” BMI with high body fat and little muscle, which carries its own risks.
- A better second check: waist circumference. For men, a waist over about 40 inches (102 cm) signals elevated risk regardless of BMI.
- Age matters too: men lose muscle with age, so the same BMI at 60 usually means more body fat than at 25.
Use BMI as a first screen, then body-fat percentage and waist size for the real picture.
BMI chart for men: healthy weight by height
Every boundary computed from weight = BMI × height² — the same arithmetic the calculator runs.
A BMI chart is the calculator with the answers filled in ahead of time. For each height it prints the two weights that land exactly on the edges of the CDC’s healthy band — 18.5 at the bottom, 24.9 at the top — computed from weight = BMI × height² and cross-checked against the calculator above at ten heights in both unit systems. The mens BMI chart below runs from 4’9″ to 6’3″, in kilograms and pounds, because men weigh themselves in both.
| Height | Height (cm) | Healthy weight (kg) | Healthy weight (lb) |
|---|---|---|---|
| 4’9″ | 145 cm | 38.8 – 52.2 kg | 85.5 – 115.1 lb |
| 4’10” | 147 cm | 40.2 – 54.0 kg | 88.5 – 119.1 lb |
| 4’11” | 150 cm | 41.5 – 55.9 kg | 91.6 – 123.3 lb |
| 5’0″ | 152 cm | 43.0 – 57.8 kg | 94.7 – 127.5 lb |
| 5’1″ | 155 cm | 44.4 – 59.8 kg | 97.9 – 131.8 lb |
| 5’2″ | 158 cm | 45.9 – 61.8 kg | 101.1 – 136.1 lb |
| 5’3″ | 160 cm | 47.4 – 63.8 kg | 104.4 – 140.6 lb |
| 5’4″ | 163 cm | 48.9 – 65.8 kg | 107.8 – 145.1 lb |
| 5’5″ | 165 cm | 50.4 – 67.9 kg | 111.2 – 149.6 lb |
| 5’6″ | 168 cm | 52.0 – 70.0 kg | 114.6 – 154.3 lb |
| 5’7″ | 170 cm | 53.6 – 72.1 kg | 118.1 – 159.0 lb |
| 5’8″ | 173 cm | 55.2 – 74.3 kg | 121.7 – 163.8 lb |
| 5’9″ | 175 cm | 56.8 – 76.5 kg | 125.3 – 168.6 lb |
| 5’10” | 178 cm | 58.5 – 78.7 kg | 128.9 – 173.5 lb |
| 5’11” | 180 cm | 60.2 – 81.0 kg | 132.6 – 178.5 lb |
| 6’0″ | 183 cm | 61.9 – 83.3 kg | 136.4 – 183.6 lb |
| 6’1″ | 185 cm | 63.6 – 85.6 kg | 140.2 – 188.7 lb |
| 6’2″ | 188 cm | 65.4 – 88.0 kg | 144.1 – 193.9 lb |
| 6’3″ | 190 cm | 67.1 – 90.4 kg | 148.0 – 199.2 lb |
How to read your row. Find your height; the range beside it is your healthy weight span. The same range is what the BMI men calculator above prints next to your result — at the defaults, a man of 5’10” gets 128.9 – 173.5 lb, which is this chart’s 5’10” row exactly. Read yourself against the tool’s own readings: that same man at 180 lb scores 25.8, just into the overweight band, and at 160 lb he scores 23.0, mid-healthy. Your row, your weight, one comparison — that is the whole method.
Why the rows widen as they climb. Because height enters the formula squared, the healthy span grows fast: at 5’3″ the band is 36 lb wide (104.4 – 140.6 lb), while at 6’5″ it spans 54 lb (156.0 – 210.0 lb). Two consequences follow. Short men are judged by a narrow window — a few pounds of muscle or fat moves the category — which is one reason BMI reads harshly at the short end. Very tall men get a wide window and a systematically kinder reading: at the same body composition, a tall frame dilutes the index, so a 6’5″ man can sit mid-band while carrying more fat than his BMI suggests. The chart is exact arithmetic; the interpretation at the extremes is where care belongs — which is what the next two sections are for.
The same chart in round metric heights. The main table is keyed to feet and inches because that is how most men in the US and UK state their height, but if you think in centimetres, the anchor rows are these — the same 18.5 and 24.9 boundaries, nothing else changed. A man of 180 cm, for example, is healthy between 59.9 and 80.7 kg; the calculator’s metric mode works to exactly these boundaries. One metric read to fix the method: a man of 175 cm at 76 kg divides 76 by 1.75² — 3.0625 — and gets a BMI of 24.8, just inside the top of his row; at 77 kg the same division returns 25.1 and he is “overweight” by a single kilogram. The band edges are exact; bodies near them should be read with the waist checks in the next sections, not by the kilogram.
| Height | Healthy weight |
|---|---|
| 160 cm | 47.4 – 63.7 kg |
| 165 cm | 50.4 – 67.8 kg |
| 170 cm | 53.5 – 72.0 kg |
| 175 cm | 56.7 – 76.3 kg |
| 180 cm | 59.9 – 80.7 kg |
| 185 cm | 63.3 – 85.2 kg |
| 190 cm | 66.8 – 89.9 kg |
When a high BMI is muscle: the caveat, quantified
First the calculation itself, then the same-BMI pair that shows where the label breaks.
How to calculate BMI for men — the full method, once, with the calculator’s own numbers. Step 1: take your weight — 180 lb, or 81.6 kg. Step 2: take your height — 5’10”, which is 70 inches or 1.78 m. Step 3: divide weight by height squared: 81.6 ÷ 1.78² = 81.6 ÷ 3.1684 = 25.8. In imperial units the same division is written 703 × lb ÷ in². That is the entire calculation — the method to calculate BMI men rely on in clinics is this one division, and the formula is identical for women; nothing about the arithmetic is male. What is male is the interpretation, and it starts with muscle.
The same-BMI pair. Two men, both 5’10”, both 200 lb. The formula gives both the identical answer: a BMI of 28.7, squarely “overweight”. Now open the pair up. The first is a rugby forward with 14% body fat: 28 lb of fat and 172 lb of lean mass, and a 34-inch waist — 86 cm, below the WHO’s 94 cm risk line for men. The second is sedentary with 28% body fat: 56 lb of fat, 144 lb of lean mass, and a 40-inch waist — 102 cm, exactly the WHO’s substantially-increased-risk line. Same height, same weight, same BMI, opposite health pictures. BMI cannot tell them apart because it never looks inside the weight.
Where the label flips. Read the pair against the American Council on Exercise body-fat categories for men — athletes 6–13%, fitness 14–17%, average 18–24%, obese 25% and over. A man at a BMI of 28.7 whose body fat reads 14–17% is carrying fitness-band composition under an “overweight” label: the label is wrong about him. A man at the same BMI whose body fat reads 25% or more is obese by composition whatever the gentler BMI word says: the label is wrong about him too, in the other direction. The flip point is a body-fat reading, not a BMI point — which is why the calculator asks for your waist, and why a waist under 94 cm with a high BMI points to muscle, while a waist over 102 cm confirms the fat the BMI suspected.
Run the pair through the calculator’s other two readings and the tie breaks immediately. Give both men their hip measurements — the athlete at 40 inches, the sedentary man at 42 — and the waist-to-hip ratios come out at 0.85 and 0.95. On the WHO-derived bands this calculator uses for men, under 0.90 is low risk and 0.95 is already high risk: the two men who shared a BMI now sit at opposite ends of the risk scale. Their waist-to-height ratios split the same way — 34 inches against 70 is 0.49, just under the 0.5 line, while 40 against 70 is 0.57, well over it. That is the practical lesson of the pair: BMI alone ties the score at 28.7, and either waist reading, which costs ten seconds with a tape, separates them completely.
The reverse error: skinny-fat. A man of 5’10” at 154 lb has a BMI of 22.1 — comfortably “normal”. At 26% body fat he carries 40 lb of fat on a light frame, with a 36-inch waist creeping toward the risk lines: normal weight, obese-range composition, and a BMI that waves him through. In trained men BMI overstates fat; in untrained light men it understates it. Both errors have the same fix — a second measurement — and the calculator’s waist fields are there to provide it.
Where the mislabel has real consequences. Most of the time a wrong BMI category costs nothing worse than an inaccurate chart entry. It bites where an institution screens by BMI alone: some insurers price or flag applications off the index, some employers and uniformed services use it as a first gate. The better-run systems know the flaw and build in the second measurement — the US Army, for instance, follows a failed BMI screen with a circumference-based body-fat tape test before any adverse finding. If a BMI reading is ever used against you in a setting like that, the document to ask for is exactly what this page keeps recommending: a body-fat percentage or a waist measurement, recorded next to the BMI, so the composition behind the number is on file.
The guide’s own example scales the point up:
a rugby player at 6’0″ and 220 lb scores a BMI of 29.8 — a step from “obese” — on a frame built largely of muscle. Push the same build to 235 lb and the formula returns 31.9, an “obese” reading for a man whose body fat may sit in the 14–19% band. Nothing about the man changed category in any meaningful sense; only the index ran out of information.BMI by age for men — and the visceral fat caveat
The band never moves; the body behind it does. Plus the fat no tape over the belly button can fully judge.
The CDC’s bands are the same at 25 and at 65: healthy is 18.5–24.9 for every adult man. The averages tell you how unusual “healthy” is: in the National Center for Health Statistics’ anthropometric report (NHANES measurements, 2015–2016), the measured average BMI for US men was 28.8 at ages 20–39, 29.5 across 40–69 and 29.3 at 70 and over — the average man is in the overweight band at every age. Average is a description of the crowd, not a standard to aim at.
What genuinely changes with age is composition. Men lose muscle steadily from their forties onward, and fat replaces it at the same weight. Body-composition research (Gallagher et al., American Journal of Clinical Nutrition, 2000) puts numbers on it: at a fixed BMI of 25, a man’s expected body fat is about 21% in his twenties and thirties, about 23% in his forties and fifties, and about 25% in his sixties and seventies — the ACE “obese” threshold reached at an unchanged, “healthy-adjacent” BMI. Height loss adds a small mechanical push in the same direction: an inch of lost height raises the computed BMI by roughly 0.7 of a point at the same weight. A man can therefore drift from 24 to 26 across two decades without gaining a pound — and carry meaningfully more fat when he arrives.
Visceral versus subcutaneous. Not all abdominal fat is the same tissue. Subcutaneous fat sits under the skin — the layer you can pinch. Visceral fat is packed around the organs inside the abdomen, drains toward the liver, and is the depot tied to insulin resistance and cardiovascular risk. Two men with the same 38-inch waist can hold very different visceral shares, which is why waist circumference — the WHO bands for men: risk rising at 94 cm, substantially increased at 102 cm — is a strong screen but not a measurement; only imaging separates the depots. The practical upshot: a rising waist at a steady BMI is the signature of visceral gain and muscle loss arriving together, and it is the trend worth acting on even when the BMI category never changes.
The same man, twenty-five years apart. Make the drift concrete. At 40, a man of 5’10” and 190 lb has a BMI of 27.3 and, say, 21% body fat: 40 lb of fat over 150 lb of lean mass. Hold his weight exactly constant to age 65 — no gain at all — and let composition follow the published pattern, reaching 28% body fat: he now carries 53 lb of fat over 137 lb of lean mass. 13 lb of muscle have quietly become 13 lb of fat; his BMI has not moved a tenth of a point; his waist has likely grown from 36 inches toward 41 as the new fat settles viscerally. This pattern has a name in the literature — sarcopenic obesity, high fat with depleted muscle — and it is invisible to BMI in both directions: the index cannot see the muscle arrive in a young athlete, and it cannot see it leave in an older man.
If you want the visceral depot measured rather than inferred. Waist readings estimate it; imaging measures it. A DXA scan reports total and regional body fat and, in current software, an estimate of visceral adipose tissue mass; MRI and CT quantify it directly but are clinical tools, not health checks. Bioimpedance scales and handheld devices print a “visceral fat rating” — treat it as a trend line rather than a measurement: hydration moves it, but a rating climbing quarter after quarter at a steady weight tells the same story as a growing waist. For most men the tape is enough: visceral fat announces itself at the waist before it shows anywhere else, which is why both waist fields sit in the calculator at the top of this page.
What is worth tracking, then.
Three cheap numbers, taken the same way each time: the BMI from the calculator, the waist at the WHO midpoint (level with the top of the hip bones’ midpoint — snug tape, end of a normal breath out), and, if you train, a strength marker such as your working weights on two or three basic lifts. BMI steady, waist rising, lifts falling is the sarcopenic signature; BMI high, waist under 94 cm, lifts rising is the athlete’s. Neither story needs a laboratory to read — but both need more than the one number this page is named after.Read the three numbers the way this calculator presents them, then: BMI for the screen, waist for the central fat, and the trend across years for the composition — the reading a single score, at a single age, cannot give. Companion tools in the same set: the general BMI Calculator, the BMI Calculator for Women, and the NHS BMI Calculator for the UK presentation of the same bands.
BMI for older men: over 50, 60, and 70
The band does not change with age. The reading does.
The healthy BMI band for men is 18.5 to 24.9 at every adult age, so the chart on this page needs no age adjustment. What changes after 50 is the company the number keeps. Muscle mass begins its slow decline, fat distribution shifts toward the abdomen, and the same BMI that at 30 described a trained build increasingly describes abdominal fat at 50. The waist check becomes the essential second measure: above 102 cm at the navel marks increased risk in the general classification, and a waist-to-height ratio above 0.5 marks the same concern in height-adjusted form. A BMI of 26 with a small waist and a BMI of 26 with a large waist are different pictures, and the chart alone cannot tell them apart.
After 60, and more so after 70, two further cautions apply. Height loss from spinal compression shortens measured stature and inflates BMI computed from current height, so a carefully measured height, or a younger-adult height used for trend purposes, gives a fairer reading. And muscle loss can hide high fat inside a healthy BMI, so strength, mobility, and weight stability deserve as much attention as the number. Weight stability in later life is itself a health signal, and unintentional weight loss deserves clinical attention regardless of where BMI sits. Regional criteria add one variation: for men of South Asian, East Asian, or Southeast Asian descent, lower action points apply, overweight from 23.0 and obese from 27.5, with a waist threshold around 90 cm. The companion guide on the BMI chart for men by age works through each decade in full.
Frequently asked questions
Quick answers about BMI for men.
What is a healthy BMI for a man?
Between 18.5 and 24.9 — the CDC’s healthy band, identical for all adults. Below 18.5 is underweight, 25.0–29.9 is overweight, and 30.0 or above is obese. The calculator above turns the band into the exact healthy weight range for your height, which is the more useful number.
What is a healthy weight for a 5’10” man?
Between 128.9 and 173.5 lb (58.5 – 78.7 kg) — the weights that produce a BMI of 18.5 and 24.9 at 5’10”. Where you should sit inside the range depends on build and muscle mass; the middle suits most men, the top of it suits heavily muscled ones.
Can a muscular man have an obese BMI?
Yes. BMI counts total mass and cannot see its composition: a rugby build at 6’0″ and 220 lb already scores 29.8, and at 235 lb the formula returns 31.9 — an “obese” reading that can coexist with body fat under 20%. A waist under 94 cm and a body-fat reading are the checks that decide whether the label means anything.
Does BMI change with age for men?
The band does not — 18.5–24.9 at every adult age. The body behind it does: muscle is lost and fat gained at the same weight, so expected body fat at a BMI of 25 rises from about 21% in a man’s twenties and thirties to about 25% in his sixties and seventies (Gallagher et al., 2000). An unchanged BMI at 60 is not the same body as at 30.
What waist size is healthy for a man?
Under 94 cm (37 in) in the WHO’s bands for men. From 94 to 102 cm the risk of metabolic complications is classed as increased, and over 102 cm (40 in) as substantially increased. Waist is the essential second reading alongside BMI — it is where the fat BMI cannot locate announces itself.
How is BMI calculated for men?
The same as for everyone: weight in kilograms divided by height in metres squared, or 703 × pounds ÷ inches² in imperial units. The calculator’s default example: a man of 5’10” and 180 lb gives 703 × 180 ÷ 70² = a BMI of 25.8. Only the interpretation is sex-specific, never the formula.
What BMI counts as overweight for a man?
25.0 to 29.9. It is a screening band, not a verdict: a muscular man at 27 with a 34-inch waist and a sedentary man at 27 with a 40-inch waist share the band and little else. The sections above work both cases in full.
Is BMI accurate for athletes?
As a screen for populations, yes; as a measurement of an individual athlete, no. It systematically overstates fat in muscular men — a lean 200 lb athlete at 5’10” reads 28.7, “overweight”, at 14% body fat. Athletes should be judged on body-fat percentage and waist circumference, with BMI as background at most.
Why is BMI higher for bodybuilders?
Because muscle is dense and heavy, and the formula weighs all of it. A bodybuilder’s extra 20 lb of lean mass raises his BMI exactly as 20 lb of fat would — at 5’10”, 200 lb of either composition returns 28.7. The index was built for population averages, and a bodybuilder is precisely the individual case it cannot see.
What is a normal BMI range for a man?
18.5 to 24.9 — “normal weight” in the WHO wording, the same range as for women and for all adults. The weight that corresponds to it depends entirely on height: at 5’10” it is 128.9 – 173.5 lb; the full chart on this page gives the range for every height from 4’9″ to 6’3″.
What is a healthy BMI for a man over 60?
The same band as at every adult age: 18.5 to 24.9. Age does not change the BMI boundaries. What changes after 60 is the interpretation: height loss can inflate BMI, and muscle loss can hide high fat inside a healthy band, so pair the number with waist, strength, and weight trend.
What is the average BMI for a 35-year-old man?
There is no official average-by-age target, and population averages are not targets: an average describes what is typical in a population where overweight is common, not what is healthy for an individual. Use the healthy band of 18.5 to 24.9 and the healthy weight range for your height, plus a waist check.
How can I tell if a high BMI is muscle or fat?
Use the waist and composition checks. A high BMI with a waist below half your height and a low body-fat estimate points toward muscle; the same BMI with a large waist points toward fat. The Body Fat Calculator on this site estimates composition from tape measurements, and the guide on when a high BMI is muscle works the comparison in full.
Are BMI ranges different for men in India or Asia?
Several authorities use lower action points for Asian populations, overweight from 23.0 and obese from 27.5, because metabolic risk rises at lower BMIs on average, with a waist threshold around 90 cm for Asian men. This calculator reports the global bands; add the regional context with a clinician familiar with your background.
What waist size should a man over 50 watch?
Above 102 cm, about 40 inches, at the navel marks increased risk in the general classification, and a waist-to-height ratio above 0.5 is the height-adjusted equivalent. For Asian men, a lower threshold around 90 cm is commonly used. Measure relaxed, with the tape level.

BMI cannot tell muscle from fat, so two men with the same BMI can carry very different amounts of fat. The Body Fat Calculator estimates your actual body fat percentage from tape measurements using the US Navy method, then cross-checks it with a BMI-based estimate — together they show the range that a single BMI number hides.
