Publication Engine v2.3 · Studio edition
Changing size or orientation reflows your copy — page count may change. Very large/small margins scale down automatically to stay readable on smaller pages.
Margins shape the live text area on every page. Inside/outside swap automatically across facing pages so the spine side always gets more room.
Visual only, simulates the binding gap between facing pages. Does not affect margins or text flow.
Page 1 opens alone on the right, like a bound magazine. Off pairs pages 1-2, 3-4 from the start.
