Change the iTunes 12 Font Size to be Larger or Smaller
iTunes 12 brought about some fairly significant user interface changes to the media player app, one of which is the size of the font shown in playlist and music views. The new default iTunes font is smaller with tighter padding between list items, and accordingly it can be difficult to read for some users. But unlike most places in OS X, iTunes does offer an ability to change the size of onscreen fonts, which can help make that playlist and music text more readable.
