My laptop is a Dell XPS-13 running CentOS 7. It has a 13" 1920x1080 screen and it's a bit difficult for my mid-40s eyesight. Fedora and Debian, on this laptop, give me the option of choosing 1600x900 which is much easier for me to read but CentOS doesn't show this resolution as available.
I followed the steps I found in a post on stackexchange using xrandr, substituting 1600x900 where applicable and it worked but, once I rebooted, it went back to 1920x1080 with no 1600x900 option in settings-display.
You can put the xrandr command in your .xinitrc if you boot into text mode. I'm sure there's a place to put it for booting into GUI mode as well, though I'm not sure of the location.
You can also play around with .Xdefaults--sometimes, setting dpi can help. For example, my yoga2 has, in .Xdefaults
Xft.dpi:192
Which increases font size.
