Haha sorry for the lack of specificity, I assumed everybody's keyboard started out like mine. Yes, I am on a Paperwhite and the letters are next to microscopic. Here's a picture, as screenshots seem not to work in kterm.
In my experimenting, I thought that the letter png's themselves could stay the same and just have the area around them change so that each key is equal, so I tried to go in and edit the widths in keyboard.xml, but that changes didley squat.
