The page number is in normal size, while the chapter/section title is using a small font (
\slshape\small\MakeUppercase). The titles are pretty big if I remove the
\smallcommand. I could use Small Caps instead (and the slanted version from the slantsc package).
But then I'm wondering about the normal, professional or common headers out there. What should be the proper size of chapters and sections titles in the header, relative to the page number?
And is Small Caps (and its slanted version) a good header style for a typical book?
