@desikn My current phone (model from 2019 I believe, I bought it refurbed in maybe late 2021) has a 6.2" screen and it's slightly bigger than I'd like. I could hold a phone slightly bigger still somewhat comfortably, but I'd prefer not to.
Still, it's not a straight comparison. My phone is 14.5:7 ≈ 2.07 whereas a tablet is 16:9 ≈ 1.78, so the tablet gives you more area and width for the same diagonal.
I still don't get why phones and tablets keep growing over the years.
