Comment 19 for bug 301158

I have struggled with this as well, and consider it to be a bug. Just a reminder to anyone, the DPI settings (in GNOME, KDE, Xft, Firefox, et al.) should *ALWAYS* match the physical characteristics of your monitor. If the default font sizes chosen are too big/small, then they should be adjusted. It would be nice if there was a general "UI scale" control, but that is NOT what DPI is. Your computer should always know what the correct DPI is for all of your display device, and 10pt really should be 10/72" on ANY screen. I also don't agree with scaling pixel fonts on the web, other than perhaps as a "compatibility option" for websites designed by totally incompetent web developers.
