Height: 175cm at night
Sitting height: somewhere like 92 or 93cm
Inseam to ankles: I wear 30inch pants, so probably 30 inches
Inseam to ground: I’ve measured this very religiously before setting a surgery date.  My best measurements put me between 81 and 82cm.
Weight: 160lbs, hoping to get near 150 before surgery.  I have only a month :/
Ethnicity: white American, Irish/Italian/Nordic ancestry

I have a 46ish% inseam ratio before surgery and I’ll be close to 48.5% after.  I like my mock-ups up until about 6’3” at which point they look too long legged.  I look best at 6’1” IMO because I have a very wide frame and a good wingspan.
