Font sizes can vary on different devices because of the display pixel densities. You can get round this by using relative sizes (ems or rems). It’s easy enough to build a test page for this but it’s something you probably never find time to do. Kevin Pederson has saved us the trouble with his test page at http://kdpeterson.net/font-size-test.html. Simple but useful.
