Format your manuscript like a published book.

I usually make quite a few files of my book depending on how many edits I do on a book, but it is a good idea to set the margins correctly on all the books in case you want to self-publish. I learned this the hard way.

Format it so it looks like a book you’d find in a bookstore, one of similar genre. Single spaced. Sized according to trade paperback (5.5 x 8.5 or 6 x 9). 1/4 to 1/2 inch margins. Then print it out when you’re ready to do a final edit. It is always a good idea to do at least one paper edit.

Seeing your work resemble an actual book is the first stage of your final edits. You need to see how it physically looks. After you’ve completed all editing, you can reformat the layout and size.
