How to Format a Book in Word

AuthorBind makes book files. It doesn't print or ship books.

What to do in Word

What not to do

Don't set margins or headers by hand. The build sets them, and headers and footers from Word don't carry over.

Upload and read the check

The check lists your chapters, and any lines that look like chapter titles but don't use a heading style. Fix those in Word and upload again.

Trim sizes and margins

There are 5 trim sizes: 5 × 8, 5.06 × 7.81, 5.25 × 8, 5.5 × 8.5 and 6 × 9 inches. The inside margin follows KDP's table for your page count, and the outside margin is 0.5 inches.
