I am writing a book in lyx 1.2.0. I started out with koma-script book class because it looks good. Now the publisher tells me they want normal text to be 10.5 point times new roman, and specifies fonts and sizes for sections, footnotes, and so on.
There is 10 and 11 point, but no 10.5, so I wonder what is a "good" way to do this. I can put this in the preamble \renewcommand{\normalsize}{\fontsize{10.5}{12.5}} and redefine \section, \subsection, \footnote etc. in similiar ways. And/or possibly redefine \small, \Huge and so on. I didn't find much information about this on the net. I can't use extsizes, because it offer only a fixed set of choices, 10.5 point text is not one of them. There are so many font commands, and several levels where I might make changes. Any advice on the best approach? Helge Hafting
