Absolutely agree, but I think we are in the smaller size of the pie. I had for many years a Samsung Galaxy S4 Mini (4.3' 124mm), super small phone that I loved, then I switched to a Xiaomi Redmi 4 Pro (5.0' 141mm), reasonably small but bigger then S4 and still usable with one hand without risks. Then I switched to a Xiaomi Mi 9T for the huge body-display ratio and I always feel it's too big (6.39' 156mm) and sometimes I need 2 hands, and I've pretty big hands... Nowdays you can't find any good android phone around ~140mm in size, that I think is the perfect size.

I also used an S4 Mini for a long time (more than five years), but its size and very small weight came at the price of not having the Full HD display of its big brother S4. It didn’t even have a 720p display! Also the battery was much too weak.

Still I searched the whole year 2019 for a replacement and finally settled on the Samsung A40, which has a FullHD(+) display, reasonably good battery, all features I wanted and is still lighter than other phones of same size.

You are right, around 140mm length would be fine, and then an equivalent weight of 140 to 150g. I cannot stand these bricks with their 180, 200g of weight, no matter the display size. These are just not usable for me.
