BMI Chart
The whole BMI landscape in one computed table — common heights against common weights, every cell from the same formula the calculator uses, with the category bands underneath.
Short answer
Read the chart at your height row and weight column: BMI under 18.5 is classed underweight, 18.5–24.9 normal, 25–29.9 overweight, and 30+ obesity (WHO/CDC adult bands). At 5 ft 10 in, for example, the normal band spans roughly 129–174 lb. The chart is computed from BMI = 703 × pounds ÷ inches², so it always agrees with the calculator above it.

About the numbers
Charts make BMI's nature obvious: it only knows height and weight. A muscular 5'10" athlete at 200 lb lands in the same cell as anyone else at 200 lb — one reason the categories are screening bands for populations, not verdicts on individuals. Waist measurement, body composition and a clinician's view all outrank a chart cell.
BMI by height and weight
| Height | 120 lb | 140 lb | 160 lb | 180 lb | 200 lb | 220 lb |
|---|---|---|---|---|---|---|
| 5 ft 0 in | 23.4 | 27.3 | 31.2 | 35.2 | 39.1 | 43 |
| 5 ft 2 in | 21.9 | 25.6 | 29.3 | 32.9 | 36.6 | 40.2 |
| 5 ft 4 in | 20.6 | 24 | 27.5 | 30.9 | 34.3 | 37.8 |
| 5 ft 6 in | 19.4 | 22.6 | 25.8 | 29 | 32.3 | 35.5 |
| 5 ft 8 in | 18.2 | 21.3 | 24.3 | 27.4 | 30.4 | 33.4 |
| 5 ft 10 in | 17.2 | 20.1 | 23 | 25.8 | 28.7 | 31.6 |
| 6 ft 0 in | 16.3 | 19 | 21.7 | 24.4 | 27.1 | 29.8 |
| 6 ft 2 in | 15.4 | 18 | 20.5 | 23.1 | 25.7 | 28.2 |
BMI = 703 × pounds ÷ inches². Under 18.5 underweight · 18.5–24.9 normal · 25–29.9 overweight · 30+ obesity.
BMI categories (WHO/CDC adult bands)
| Category | BMI range |
|---|---|
| Underweight | below 18.5 |
| Normal weight | 18.5–24.9 |
| Overweight | 25–29.9 |
| Obesity | 30 and above |
Adult bands; they do not apply to children, and interpretation differs for some ethnic groups and for very muscular builds. A screening measure, not a diagnosis.
How we calculate this
The standard adult BMI formula, in both unit systems:
- Metric. BMI = weight in kilograms ÷ (height in metres)². 70 kg at 1.75 m → 22.9.
- Imperial. BMI = 703 × weight in pounds ÷ (height in inches)². 160 lb at 70 in → 23.0.
- Category & healthy range. the result is placed in the WHO/CDC adult bands, and the healthy-weight range inverts the formula: 18.5–24.9 × height².
Assumptions
- Adults only — children and teens use age- and sex-specific percentiles instead of these bands.
- BMI cannot distinguish muscle from fat, so athletes often score 'overweight' while lean; waist circumference and body-composition measures add the missing context.
- Category cut-offs differ for some populations (e.g. lower thresholds are recommended for some Asian populations).
- This is an educational screening number, not medical advice — decisions about weight and health belong with a clinician.

Frequently asked questions
How is BMI calculated?+
Weight divided by height squared: kilograms ÷ metres² in metric, or 703 × pounds ÷ inches² in US units — the 703 is just the unit-conversion constant, both give the same number. 70 kg at 1.75 m is a BMI of 22.9; 160 lb at 5'10" is 23.0. The calculator handles both systems and shows the WHO category alongside the number.
What is a normal BMI?+
The WHO/CDC adult bands are: under 18.5 underweight, 18.5–24.9 normal, 25–29.9 overweight, and 30+ obesity (with obesity further divided into classes at 35 and 40). These are population screening ranges drawn from health-outcome statistics — being just over a line is not a medical event, and the healthy-weight range for your height gives a more useful target than a single number.
Is BMI accurate for everyone?+
No, and it doesn't claim to be. BMI only knows height and weight, so it can't tell muscle from fat — many athletes class as 'overweight' while lean — and it misjudges at the extremes of height, in older adults who've lost muscle, and during pregnancy. Cut-offs also differ by population: lower thresholds are recommended for some Asian populations. It's a quick screening number; waist circumference and body-composition measures add what it misses.
What is a healthy weight for my height?+
Invert the formula: multiply 18.5 and 24.9 by your height in metres squared. At 5'10" (1.78 m) that's roughly 129–174 lb (59–79 kg); at 5'4" roughly 108–145 lb. The per-height pages on this site show the band for common heights, and the calculator computes it exactly for yours. Where you personally sit best inside (or near) the band depends on build and muscle.
Does BMI apply to children?+
Not with these adult bands. For ages 2–19, BMI is calculated the same way but interpreted against CDC growth-chart percentiles for the child's age and sex — 'BMI-for-age' — because healthy body composition changes throughout growth. A pediatrician's chart, not an adult calculator, is the right tool for a child.
Is my BMI stored or sent anywhere?+
No. The calculation runs entirely in your browser — your height and weight are never uploaded, no account, no email, nothing tracked about the numbers you enter. It's also worth repeating the framing: this is an educational screening estimate, not medical advice; decisions about weight and health belong in a conversation with a clinician who can see the whole picture.
