A page setup for each edition

A paperback, a hardcover and a large-print edition are the same book in different clothes: a different trim size, perhaps a different font size, wider margins. You don't need a copy of the book for each. You keep one manuscript and a page setup for each edition, and choose which one to use when you publish.

Make a setup for the new edition

1. Open the book and choose Page setup (in the Book menu).
2. At the top, open the Setup list and choose + New setup from this form…. Write starts the new setup as a copy of the one you're looking at, so everything you've already settled carries over.
3. Give it a name you'll recognize—Hardcover 6 × 9, say—and change what's different: the trim size, the margins, the type size.
4. Click Save setup.

Saving a new setup makes it the one this book uses from now on. If you'd like the book to go on using the original as its main setup, open Page setup again, choose the original in the Setup list, and save.

Publish with it

In the Publish window, the Page setup list chooses which setup this file is made with. The book's own setup is chosen for you; pick the other one for the other edition, then Publish PDF. Your files list keeps both PDFs, each with its own page count.

Good to know

• A setup can be shared. Every book in a series can use the same setup, which keeps them matching on the shelf. Changing a setup changes it for every book that uses it, and the bottom of the Page setup window says so before you save.
• The ebook uses the setup for its fonts, chapter openings and decorations, but not for trim size or margins—a reader's screen decides those.
• Front and back matter that differs between print and ebook is set on the section itself, not in the setup; see Choose where a section appears: print, ebook or both.
