★ HEALTH · IDEAL WEIGHT · BMI 18.5–24.9
On the defaults — 5'9" (69 in) and 160 lb — the BMI is 23.6, a healthy weight, and the healthy range for 5'9" is 125–168 lb (56.7–76.2 kg): overweight starts at 169 lb and obesity at 203 lb. Put in your height and weight and the calculator works out your BMI, your category, and your own healthy range — and works backwards when you have a target BMI instead. The BMI calculator gives one person’s BMI; this page is the full lookup table — every height from 4'10" to 6'6" with its healthy range in pounds and kilograms plus the overweight and obesity thresholds — and the calculator below it checks your height and weight against the same table.
BMI is weight in kilograms divided by height in metres squared, and the healthy band is a BMI of 18.5 to 24.9. Put in your height and weight and the calculator works out your BMI, your category, and your healthy range in pounds and kilograms — and works backwards when you have a target BMI instead.
The healthy weight for a height is the range of whole pounds whose BMI is 18.5 to 24.9 — the WHO/CDC healthy band. Overweight starts at the first pound whose BMI displays 25.0, and obesity starts at the first pound whose BMI displays 30.0. Every row below is the same calculation as the calculator above, so a weight listed as healthy always shows a healthy BMI.

On the defaults — 5'9" (69 in) and 160 lb — the BMI is 23.6, a healthy weight, and the healthy range for 5'9" is 125–168 lb (56.7–76.2 kg), with overweight from 169 lb and obesity from 203 lb. The whole chart is three moves: convert the height and weight, divide for the BMI, and read the range off the same BMI bands.
Five things about the model are worth stating plainly. First, BMI is weight in kilograms divided by height in metres squared — 160 lb is 72.57 kg and 69 in is 1.7526 m, so 72.57 ÷ 1.7526² = 23.6. Second, the category is read from the displayed BMI: under 18.5 is underweight, 18.5 to 24.9 is healthy weight, 25.0 to 29.9 is overweight, and 30.0 and over is obesity. Third, the healthy range is the whole pounds whose displayed BMI is 18.5 to 24.9 — for 5'9" that is 125–168 lb, or 56.7–76.2 kg. Fourth, the first overweight pound is always the healthy high + 1 — 169 lb for 5'9" — so the table never contradicts the category the calculator shows for the same weight. And fifth, BMI is a screening guide, not a diagnosis: it does not separate muscle from fat, and it misses age, sex, pregnancy, and ethnic differences; all listed in Accuracy & limitations.
Setup: 5'9" (69 in), 160 lb.
Line 1 — convert the weight and height. The weight is 160 ÷ 2.20462 = 72.57 kg and the height is 69 × 0.0254 = 1.7526 m.
Line 2 — divide for the BMI. The BMI is 72.57 ÷ 1.7526² = 23.6.
Line 3 — read the category. A BMI of 23.6 is between 18.5 and 24.9, so the category is Healthy weight.
Line 4 — read the range off the table. The healthy range for 5'9" is 125–168 lb (56.7–76.2 kg), overweight starts at 169 lb, and obesity starts at 203 lb.
6'0", 200 lb: Height 6'0" (72 in), weight 200 lb: BMI 27.1, Overweight, healthy range 137–183 lb (62.1–83.0 kg), overweight from 184 lb, obesity from 221 lb — At 6'0" and 200 lb the BMI is 27.1 — overweight, 17 lb above the top of the 137–183 lb range.

Weight for a BMI of 25.0 (the overweight threshold) at 5'9": 169 lb — the exact weight is 169.2931 lb. At the displayed 169 lb the BMI is 25.0 (exact 24.9567) — overweight. 168 lb gives a BMI of 24.8, healthy weight; 170 lb gives 25.1, overweight. The star is POUNDS.
Weight for a BMI of 18.5 (the healthy low) at 5'9": 125 lb — the exact weight is 125.2769 lb. At the displayed 125 lb the BMI is 18.5 (exact 18.4591) — healthy weight. 124 lb gives a BMI of 18.3, underweight; 126 lb gives 18.6, healthy weight. The star is POUNDS.
Height at which 200 lb first becomes healthy: 6'4" (76 in) — the smallest whole-inch height where 200 lb is healthy. At 6'4" the BMI is 24.3; at 6'3" it is 25.0, overweight — one inch shorter and the same 200 lb is overweight. This is a step reverse: height comes in whole inches here, so there is no exact in-between. The star is INCHES.
Weight for a BMI of 30.0 (the obesity threshold) at 6'0": 221 lb — the exact weight is 221.2012 lb. At the displayed 221 lb the BMI is 30.0 (exact 29.9727) — obesity. 220 lb gives a BMI of 29.8, overweight; 222 lb gives 30.1, obesity. The star is POUNDS.

The math is first-principles: BMI is weight in kilograms divided by height in metres squared, shown to 1 decimal, and the category is read from that displayed BMI; the healthy band is 18.5 to 24.9, overweight starts at 25.0, and obesity starts at 30.0, following the WHO/CDC bands. The table’s ranges are whole pounds: the low end is the lightest whole pound whose BMI still displays 18.5 or higher, the high end is the heaviest whole pound whose BMI still displays 24.9 or lower, so a weight listed as healthy always shows a healthy BMI in the calculator, and the first overweight pound is always the healthy high + 1. What the model cannot do is diagnose you: BMI is a screening guide, not a diagnosis — it does NOT separate muscle from fat; it does NOT account for age, sex, pregnancy, or ethnic differences; and a single number cannot set a personal target. A clinician weighs all of that for a personal target. Use the chart to see where you stand — then talk to a clinician before acting on it.
