BMI Chart by Height and Weight

Every value below is calculated as weight in kilograms divided by height in metres squared, then rounded to one decimal place. Colour marks the WHO band: blue is underweight, green is normal weight, amber is overweight, red is obese. The number in each cell is the BMI itself, so the table is still readable if the shading does not come through when you print it.

A worked example: at 175 cm and 75 kg the maths is 75 ÷ (1.75 × 1.75) = 24.5, which sits in the green band with about 1.5 kg of room before the overweight threshold. That narrow margin is the single most useful thing to notice on this chart — across these heights the normal band is only 14 to 24 kg wide, so a few kilograms of water weight or a heavy meal can move you across a line that sounds far more meaningful than it is.

Reading the grid backwards is usually more practical than reading a single BMI forwards. If you want to know what to aim for rather than where you currently sit, the table below solves the same formula for weight instead: it gives the span that corresponds to a BMI of 18.5 to 24.9, plus the exact weights at which each height crosses into the overweight and obese bands.

Notice how wide these ranges are. At 180 cm the healthy band spans roughly 60 to 80 kg — a 20 kg window covering physiques that look nothing alike. That is a feature of BMI rather than a fault: it was built to flag populations worth a closer look, not to prescribe one correct weight for one person. If you want a single target number, the ideal weight calculator applies four older clinical formulas that each return one figure, and the ideal weight chart shows how far apart those four formulas actually land.

The four adult bands are the WHO classification, unchanged since 1995 and used more or less universally in public health reporting. They are the same for men and women, and the same at every adult age.

Two details are widely misread. The bands describe statistical risk across large groups, not a diagnosis for an individual — plenty of people in the amber band have entirely normal blood pressure, blood lipids, and glucose control. And the boundaries are round numbers chosen for convenience: nothing physiological happens between a BMI of 24.9 and 25.0.

A shaded grid looks more authoritative than the underlying measure deserves, so it is worth being explicit about the cases where the colour is simply wrong for the person.

• Muscular builds. BMI cannot tell muscle from fat. A trained 180 cm lifter at 98 kg reads as obese on this chart at a body fat percentage that is objectively low. If that describes you, the body fat calculator and a waist measurement will tell you far more than this table.
• Older adults. Muscle mass falls and fat mass rises with age at a stable body weight, so an unchanged BMI can hide a real change in body composition. Some evidence also suggests a slightly higher BMI is not harmful after about 65.
• Very short and very tall people. Dividing by height squared under-corrects at the tall end and over-corrects at the short end, which nudges tall people toward higher BMI values and short people toward lower ones for the same build.
• Where fat is stored. Two people can share a cell on this grid with very different amounts of visceral fat, and that difference matters more for metabolic risk than the BMI does. Waist circumference is the cheap fix.
• Anyone this chart is not built for. It applies to non-pregnant adults only. Children and adolescents are scored against age- and sex-specific percentile curves, not these fixed bands, and pregnancy invalidates the comparison entirely.

Our guide on what BMI does and does not tell you goes through the evidence behind each of these in more detail.

Both tables carry imperial equivalents so you do not have to convert anything. Row labels show height in centimetres with the nearest feet and inches, and column labels show weight in kilograms with the nearest pounds. Because the chart steps in whole units of 5 cm and 5 kg, the imperial figures land on uneven numbers — 175 cm is 5'9" to the nearest inch, and 75 kg is 165 lb to the nearest pound.

If you would rather work directly in pounds and inches, BMI can be calculated as 703 × weight in pounds ÷ height in inches squared, which produces the same value as the metric formula. The BMI calculator accepts either unit system and does the conversion for you, which is the better option if your height falls between the 5 cm steps used here.
