A:Answer Hi there! The font is extremely customizable on the Kindle Paperwhite, by default I would say it's about the same size as a standard mass market paperback book that you'd find at the library. To adjust the font sizes just tap at the top of the screen and then the 'Aa' symbol. Not only will this allow you to adjust font size, you can adjust things like the margin or even the orientation of the device! I hope that helps, have a great rest of your day!
