Hobbit survey on the diagonals of smartphones

Choosing a smartphone, I feel like a hobbit in the country of normal people. And we are not talking about excess hair on the lower limbs or amazing endurance, exploited by some brazen wizards. It's about the size of these same phones. Most powerful models come with amazing diagonals, sort of “tablet phones” (“shovels”?) With a diagonal starting at 4.5 inches. For me, 4.3 is the size limit with which you can operate with one hand. I would prefer to take a smaller one, but for the combination “Android 4.4+ decent battery + price less than $ 400,” the choice turned out to be simply none.

In this regard - the survey. What is the screen diagonal of your smartphone ? I will highlight this word, because the dialer can be quite small in size, but a survey about trends and preferences in the smartphone area.
