I disagree - I say it's your inseam (Leg length).
I have a 28" inseam
I was 'used' to 170s cause that's what came on 90 percent of bikes out there. I picked up a small mid-80s Trek with 165s and immediately got used to that with no issues at all. I later found an old 1960s Rudge "colt" 3-spd for young teens - short top tube, but standard 26" wheels. It had 140mm cranks. sure, it was not the zippiest ride uphill, but again, the comfort was there for me right away. No adjustment time needed.
I finally went back to my old bike with 170s after several months and it SUCKED! It was like my knees were being violently jerked around.
