Mine don't match up. I can fit 4/4.5/5 for ring but the latter would be a tad too loose. My band's a 4.5 and it still slides off, and if I tried at times, I can even "fling" it off--depending on the season. LOL.
Shoe size has forever been a US 6. Though I have had some 5.5 types fit me (sneakers), but with some healed/pointed dress shoes/pumps, I go higher only because I have wide feet.
I believe my arm length might have matched my height when I measured it many years back. Might have shrunk since then.

Still 5' 5" and two millimeters now.

Wow, so my height almost matches up to shoe size in numbers!
