More than arm-lenght. I put the text in for instance Firefox to 125-140% normal size to make it all easier to read. Too close isn't something my eyes like, and I even use f.lux to cut down on the blue light and also take down the brightness on the monitor itself.How far are you people sitting from your monitors? Don't you like the monitor square within the middle of your view. This is what I prefer and don't get people that want a huge 'cliff face' of monitor in front of them at a desk, that they have to constantly move their line of vision to take in all 4 corners, it must be rather fatiguing.
