This is not unusual. People think font typefaces are useable at all kinds of different sizes and that's not true. Professional typographers will tell you that certain font typefaces are designed to be viewed at certain sizes. When the size goes beyond or below the original design, that font typeface will need to be slightly adjusted (usually manually) to make it optimised. In fact, this is still a problem despite font technologies like TrueType that allow fonts to scale. Automatic scaling doesn't entirely work.
But at this point of the conversation, we're not talking about PDF or any other digital book format but rather the problem of typeface. I just want to make that clear.
