To start, it's true that none of this matters in the least when it comes to 'are you trans or not'. I remember when I first started, I went through a period where I measured *everything*. Some parts fit the pre-natal hypothesis, some parts didn't. What I found out later was that these things are a crazy distraction from doing the work of getting on with your acceptance of self and, while particular parts are nice for some kind of validation, nothing is going to fix the fact that I was still born with a body that was going to mature into the wrong sex and that's that so, while I'll play the data points game, I'd really encourage newbies to treat this stuff as what it is: traits. It's about the same thing as your hair color and just as relevant.
That said, just for the data points:
3.2 Width \
7.0 Length |- Inconclusively male or female though typical for my size.
7.9 Circumference /
2d4d Digit ratio has 2d longer by about 1/8". - Signs point to limited testosterone exposure
Carry angle on arms is difficult to measure at this point due to the fact that I work out a lot. Seems to be around 167º or so.
Upper to lower arm ratio: = 1.37 (female typical)
My hands are actually pretty well proportioned to my frame and the extra finger length is nice for the simple ability to open jars. The only thing I don't like about having larger hands is the lack of gloves available in that size.
P.S. Fingers be damned, nothing changes the larger than should be rib cage, shoulders, or deeper pelvic girdle... uggh.
