That would be a solution, of course; but I don't think there is anything wrong with that. The first example I gave was about redefining normalsize, which I had to do in a book ---you just can't go without using normalsize.

Ah! Good point ---if the OP needs to use math, but can't use anything below 7pt, that would be a problem. But the document you refer to wonderfully explains in a few lines what to do.

The OP asked:

>> Can you tell me how you (or I) would know the defined font sizes for a given class, like your book class example?  Where do you look for such information, etc.

Well ---such information is in the bkXX.clo (for book class) and sizeXX.clo (for article, report and letter classes).

I never advised modifying .clo files! I clearly said

Yes, this is really good, as different font families might require different adjustments, though usually package writers take good care of that.

Yes, I have seen those examples ---very good to have a grasp on the complexities of font design.

More than advertising, if one is able to, I think is a good advice.
