How to calculate your true height

fizzy123

Hi,
I remember reading somewhere how to calculate your true non scoliotic height, vaguely recall something about arm length... does anyone have any references or experience calculating this and if so did you use it for your BMI and other Stats to calculate your goals ect.....

Thanks in advance.:flowerforyou:

I'm interested to see that! I've lost 2 inches in the last 20 years and am shorter than anyone else in my family. I just used my true height to calculate my goals though.

Sourced the article about computing the projected height based on arm span et al. I figured that I should be 5'8.5" instead of 5'6" , two curves one lumbar and other thoracic. Makes sense now that I think on it as my daughter is 5' 10" and also my sister !!

Here's some information on Scoliosis I found helpful in describing the condition.

Hope you all find it as interesting as I do. :happy:

Edited to Add quote from article on Medscape: that confirms we should be using corrected height for BMI measurments ect..
Abnormal Skeletal Growth Patterns in Adolescent Idiopathic Scoliosis

Anthropometric Measurements

Body weight, standing height, and arm span were measured using standardized techniques at the first visit.[17,18] Body weight was measured in light clothes without shoes on an electronic balance. Body height was measured with the patient standing upright against a wall-mounted stadiometer without shoes, head positioned in a horizontal plane, and heels against the stadiometer. For subjects with scoliosis, corrected height was calculated from the Bjure formula[19] (log y = 0.011x − 0.177) where y is the trunk height loss (in cm) and x is the major Cobb angle (in degree). Arm span was also measured using a wall-mounted ruler, with the subject's arms fully stretched horizontally and parallel to the ruler. Body mass index (BMI) was calculated from the formula (Weight [kg]/square of height [m2]). For patients with AIS, the corrected body height was used for BMI calculation. Age of menarche was recorded.

I am 5'6 1/2" (and used to be 5'7")

According to the formula in BBC, I should be 5'9".
According to the formula for trunk height loss, I should be 5'7"
