Can I request that my book be a specific number of pages?

Can I request that my book be a specific number of pages?

This is generally not a good idea, because it would mean that we would either have to increase/decrease the size of the typeface and/or the line spacing to suit.  While this may sound like a reasonable solution, we want your book to look as professional as possible and having an internal layout that goes against the norm purely for the sake of a desired page count is really not a good idea.  At best, it’ll look unprofessional.  At worst, people may refuse to read it if the layout jars.  Please trust that whatever type size and line spacing we provide you with will be the most suitable for your book, genre, and the industry in general.
