Choose a simple and easy-to-read font to feature as your main textual font. A basic serif font is often considered the most appropriate for the primary text of a book because of its aesthetically appealing appearance.
Select a different font for the running heads and chapter titles to bring accent to the appearance of your book. This will increases appeal and help you sell the book because of its professional appearance.
Layout text with an established program specifically designed for typesetting. Simple word processing programs usually lack the sophistication to space characters properly and to a professional standard.
Convert the document into a PDF format so that professional printers can replicate the quality you have previewed on your computer screen.
Remember to proofread the text before sending it off for the final print job. A book will not sell if its appearance is marred by obvious grammatical and usage errors.
Remain consistent in subsequent book layouts so that you save yourself time and energy with each new book. With smaller and micro presses this is even more important.
