Fixing your TEX header to make your PDF suitable for book interiors

If you open your generated TEX file in your favorite text editor you'll see a bunch of lines in the beginning of the file and the last line of the bunch is this:

%%% Body

Replace all of those lines with these:

\documentclass[12pt]{book}
\usepackage{geometry}
\geometry{
papersize={7.5in,9.25in},
inner=.88in,
outer=.5in,
headheight=.5in,
bottom=.5in,
}

\usepackage{fancyhdr}

\pagestyle{fancy}
\fancyhf{}

\fancyhead[CO]{Your Book's Author}
\fancyhead[LE,RO]{\thepage}


\fancypagestyle{plain}{%

%%% Body

I have bolded the parts of the TEX file that you will likely want to change. The first one is the page size. I have found two page sizes to be useful:

1. 6x9 inches for novels. I also use this for Hindu scriptures, and it might work for other kinds of titles like biographies, etc. This is a very common size for published books.

2. 7.5x9.25 for non fiction titles, especially illustrated ones. If your book has full page illustrations or lots of diagrams this is a good size. You can't really do full page illustrations with TEX and making the page size larger compensates for that. Also, when choosing an illustrated book to put back in print avoid color interior illustrations. A print on demand book needs to print every page the same way, so you're paying for color on every page whether the book needs it or not, and the color pages just don't look that good.

Most conventionally published books with photographs or color illustrations print the illustrations separately from the rest of the book and glue those pages into the rest of the book as part of the printing process. You can't do that with print on demand. Your pictures will look like they were printed on regular quality paper using an InkJet printer. For black and white photos this can give usable results, for color not so much.

The place for color and color illustrations is on the book cover. That is where they will look their best.

There are several places to put in your book's title and author. In the printed book left hand page headings will have the title and right hand page headings will have the author name. There are probably ways to get LaTeX to do fancier things with page headings but I never bothered to learn how.

More details on how to nicely format your book interior to come. Stay tuned.
