The feature that defines a layout application
In a drawing program, every text box is an island. In a layout application, frames are threaded: text flows from one into the next, across columns and across pages, and inserting a paragraph on page 3 reflows everything after it automatically.
This is the single feature that makes long documents possible, and it is why CorelDRAW becomes painful past twenty pages.
Threading, unthreading, and seeing the thread
- InDesign: click the out-port (the small box at the bottom right of a frame), then click the next frame, or click an empty area to draw a new one. View ▸ Extras ▸ Show Text Threads (Ctrl+Alt+Y) draws the links. Shift-click the out-port with a loaded cursor to autoflow, creating pages as needed until the story ends.
- Scribus: select the first frame, click the link-text-frames button (or press N), then click the target. The unlink button breaks it.
- Affinity Publisher: the same out-port model as InDesign, with Auto-flow on the Text Frame panel.
Threading is directional. Moving a frame does not change its position in the thread, which is why a frame on page 12 can be the eighth in a story that started on page 3.
Overset text
When a story is longer than the frames holding it, the surplus is overset: still in the document, not displayed anywhere.
This is the most dangerous failure in layout, because it is silent on a printed proof. The paragraph is not there, and nobody notices until a reader does.
Every application marks it:
- InDesign: a small red + at the frame’s out-port, and a count in the Preflight panel.
- Scribus: a red cross in the bottom-right corner of the frame, plus an entry in the Preflight Verifier.
- Affinity Publisher: a red triangle on the frame edge.
Check for overset before every export, every time. It costs two seconds and it is the reason the preflight panel exists.
Copy fitting is a design decision
When copy will not fit, there are five moves and they are not equally honest.
- Edit the copy. Cut forty words. Almost always the best answer, and the one nobody wants to make.
- Add a page. Cheap in digital printing, and in a bound job the count must be a multiple of four, so it may mean four pages.
- Change the style globally: 9.5/13 instead of 10/14 throughout. Legitimate, provided it is applied through the style so the whole document stays consistent.
- Track the offending paragraph by −5 or −10 thousandths of an em. Acceptable in small doses; visible as a change in colour if overdone.
- Scale the type horizontally. Never. It distorts the letterforms and is visible beside any undistorted paragraph on the same spread.
InDesign’s Story panel and the Keep Options in a paragraph style let you automate some of this. Whatever you do, do it through a style, not by selecting text: otherwise you have created a local override, and the earlier lesson explained where that ends.
Smart text reflow and the pages that vanish
InDesign’s Smart Text Reflow (Preferences ▸ Type) adds and deletes pages automatically as a story grows or shrinks. It is useful for a long text-only document and actively dangerous in a designed one, because it can delete pages you placed images on.
If you use it, set Limit to Primary Text Frames and Preserve Facing-Page Spreads. If your document is designed rather than flowed, switch it off.
Placing text without losing control
Use Place (Ctrl+D) rather than copy-paste for any substantial copy. Placing lets you keep or discard the source formatting, map Word styles onto your paragraph styles, and re-link to the original file.
Mapping Word styles onto InDesign styles is the single biggest time saving available on a long editorial job. Show Import Options on Place, then Customise Style Import, and map “Heading 2” to your “B-Head” once. Every subsequent import is instant.
Before any of that, run a clean-up pass on the source text: find-and-replace double spaces, empty paragraphs, manual line breaks and tabs used as indents. Five find-and-replaces on the raw text will save you an hour of fighting the layout later.
Every lesson here is open. Your progress is recorded once you pass the Editing an Image exam.
Check your understanding
A 48-page brochure is proofed, approved and printed. A reader points out that a paragraph referenced in the contents list does not appear anywhere in the book. The file opens with no error and the text is still in it. What happened?
