Males: IBW = 50 kg + 2.3 kg for
each inch over 5 feet.
Females: IBW = 45.5 kg + 2.3 kg for each inch over 5 feet
Your IBW is calculated to be 61.5 kg, so you are currently about 22% below your ideal body weight. In addition, your body mass index (BMI) is 17.6, which is considered underweight.
With your height and age, you are in the 5th percentile when plotted on the Growth Curve Chart of the Bayley-Pinneau method. So, by definition, you are not in the short stature category.
