Ideal weight for a 6'3" woman
In kilograms, for Indian adults, using the Asian-Indian healthy BMI band — shown as a window on the scale rather than as a target.
Healthy weight range · Asian-Indian scale
67.1–83.1kg
A woman of 6 feet 3 inches (190.5 cm) has a healthy weight range of 67.1 kg to 83.1 kg — that is 148 to 183 lb — using the Asian-Indian healthy BMI band of 18.5 to 22.9. A range, never a single figure: the method cannot support that much precision.
On the standard WHO scale the range extends to 90.4 kg, because that scale allows BMI up to 24.9 before calling it overweight. The 7.3 kg between the two is exactly the difference this site exists to explain.

Why this site reads 23 and not 25 — the full argument, with the 2004 consultation quoted →
At 6'3", the outlined window is the healthy range on the Asian-Indian scale: 67.1 – 83.1 kg. The shaded columns are where the two rulebooks return different verdicts for the same body — 83.5 to 90.7 kg and 99.8 to 108.9 kg at this height.
Sources: WHO Expert Consultation on BMI in Asian populations, The Lancet 2004 (action points 23.0 and 27.5); WHO retained the international classification at 25 and 30. Weights are those cutoffs at 190.5 cm.

How the Asian-Indian reading is derived
- Height is converted to metres. 190.5 cm becomes 1.9050 m.
- BMI is weight in kilograms divided by height in metres squared. The formula contains no sex, age or ethnicity term.
- The result is read against two published band sets. The Asian-Indian action points (23.0 and 27.5) come from the WHO expert consultation for Asian populations; the international classification (25 and 30) was deliberately retained by the same consultation.
- Healthy weight is reported as a range, never a single figure: the BMI 18.5 and 22.9 bounds are each multiplied by height squared.
- Where the two band sets return different verdicts, the gap is shaded in the diagram and stated in kilograms rather than left implied.
healthy weight = 18.5 x (1.91)^2 ... 22.9 x (1.91)^2 = 67.1 kg ... 83.1 kg

Highlighted rows fall in the healthy band on the Asian-Indian scale (BMI 18.5–22.9). BMI = weight in kg ÷ (height in metres)². Height taken as 190.5 cm.

Sex, build and what BMI cannot see
No adjustment is applied for sex, because BMI has no sex term. A woman and a man of 6'3" get the same range from this method. That is a real limitation rather than an oversight — women carry more essential body fat at a healthy weight, and BMI cannot see it. The women and BMI guide covers what that means in practice.
The Devine reference
For a female of 6'3", the Devine formula gives 80.0 kg. It is shown because people search for it, not because it is better. It was published in 1974 as an aid to drug dosing, it returns a single number, and it takes no account of build.

What ±5 kg looks like here
| Weight | BMI | Asian-Indian | Standard WHO |
|---|---|---|---|
| 65 kg | 17.9 | Underweight | Underweight |
| 70 kg | 19.3 | Normal | Normal |
| 75 kg (middle of range) | 20.7 | Normal | Normal |
| 80 kg | 22.0 | Normal | Normal |
| 85 kg | 23.4 | Overweight | Normal |
Five kilograms moves BMI by about 1.4 points at this height — which is why a 5 kg change matters more for a shorter person than a taller one.
Questions
What is the ideal weight for a 6 feet 3 inches woman in kg?
67.1 kg to 83.1 kg. That is the healthy BMI band for Indian adults (18.5 to 22.9) applied to a height of 190.5 cm. Anywhere inside that range is a reasonable place to be; there is no single correct number.
Is 75 kg a good weight for a 6'3" woman?
75 kg at 6'3" gives a BMI of 20.7, which is normal on the Asian-Indian scale and normal on the standard WHO scale.
What does the Devine formula give for 6'3"?
80.0 kg for a female of this height. Devine published the formula in 1974 for calculating drug doses rather than defining health, and it returns the same number for every woman of a given height regardless of build. Treat it as a historical reference, not a target.
