Here's why the comparisons in the web site mentioned by the OP are not realistic:
They ask you for a measurement and then they compare that measurement to that of the "average" male or female in the US, according to whatever census or statistics they got them from.
PROBLEM IS:
That the average man and woman used for the calculations, has AN AVERAGE height, that may or may not match with yours, so if you are much taller (like me) than that average person, or maybe much shorter, then those averages will simply make no sense at all. Unless of course they told you, in your result, something like this: the average woman used for this calculation is X feet tall. Or better yet, that for every single comparison they asked you your height first, so they could compare you with someone your height.
Here's something that does make sense to me:
About six years ago, when I was about to start HRT, I found a very comprehensive table of body measurements for men and women, from a web site named Second Type Woman. So I copied that in a file and I started checking my measurements to compare to that table.
But, in order to make such measurements MAKE SENSE, I needed to find out what was the average height for the average woman used in the table, and then calculate a factor, to apply to the difference between my height and the height of the average woman in the table, and then re-calculate the figures to accommodate them to a woman MY HEIGHT.
So the female height for the table (the average female height that is) was 64.25 inches. That is, 163.2 meters or 5.354 feet.
Since I am exactly six feet tall, in order to get the conversion factor, I divided 6/5.354 = 1.120
Which means that in order to convert those "average measurements" of a woman into a woman MY HEIGHT, I would have to multiply by 1.12065. This way the table would MAKE SENSE to someone my height.
Here's an example:
The female neck circumference measurement says 13.10 inches, but this is for a 5.354-foot woman, much shorter than me. So I multiply by the factor, 1.12065 and I get 14.68 inches. That would be the women's neck measurement for a woman MY HEIGHT. I measured my neck, it measures 14 2/8", that is, 14.25 inches, so I actually have a THINNER NECK than an average woman my height in the US!
The hand length measurement, for that 5.354-foot woman, is 7.10 inches. So my 7 5/8 (7.625) inch size may look like too much, but making the conversion, a woman my height would measure 7.95 inches, so again I measured LESS than a woman MY HEIGHT!
The foot length measurement: I measure 10.55 inches (26.8 centimeters). My women's shoe size US is 10.5 BTW, so I wear size 11 for flats and a bit bigger for high heels if they are taller than three inches. According to the table, the 5.354-foot woman measured 9.58, so I convert it to my height and the result is 10.735, AGAIN, I measured LESS than a woman MY HEIGHT!
Bottom line, I really hope that other women who may feel MISTAKENLY SELF-CONSCIOUS about their measurements because of that table, come to realize that the comparisons that that website makes are useless, unless you are casually exactly the same height as the person they used as a calculation subject for such comparisons.
