Frequently asked questions
We’re here to answer your questions
Will PublishPro calculate my margins and gutter automatically?
Yes. Simply choose your trim size, and PublishPro automatically calculates your margins, gutter, and bleed based on your current page count and print requirements. If your manuscript grows or shrinks, everything updates automatically before export.
Can PublishPro clean up extra spaces and irregular line breaks in my manuscript?
Yes. During import, PublishPro detects and removes irregular spacing, unnecessary line breaks, and common formatting inconsistencies to create a cleaner, more professional layout.
Will my Table of Contents update if I edit my book?
Yes. Your Table of Contents is generated from your manuscript structure and updates automatically whenever chapters are added, removed, or reordered. Final page numbers are refreshed when your PDF is generated.
Do I need to calculate my paperback cover size myself?
Upload your cover design and PublishPro automatically calculates the correct spine width, bleed, and cover dimensions based on your trim size, page count, paper type, and printing platform.
Will my paperback meet Amazon KDP and IngramSpark requirements?
Every export is prepared to match the latest print specifications for Amazon KDP and IngramSpark, including margins, gutter, bleed, trim size, fonts, and cover dimensions.
What happens if I change trim size after formatting?
PublishPro automatically regenerate your layout, margins, gutter, Table of Contents, and cover specifications when the final PDF is generated, so you don't have to start over.
Can I customize the formatting after PublishPro finishes?
Once your book is formatted, you can change templates, typography, chapter styles, headers, footers, scene breaks, and other design elements without rebuilding your entire book.
