Same height. Before they started selling those exit row seats for more money I used to ask the flight attendants to let me move if there was room available. It seemed to help if I stood up extra tall so that my head would be close to the roof, they hooked me up a few times (I didn’t fly that often back then anyway), especially on littler planes were I looked like a giant.

I have many sat in a normal seat in a while since my the person who books my flights is also tall and gets me the extra legroom seats automatically now. So I’m spoiled.

Really there should be safer seat spacing for tall people though, but I’m not holding my breath.
