Quick answer
Combine font size with text size, spacing, margins, page color, and movement in that order. Keep each change small.
The settings should work together instead of fighting each other.
Recommended order
Use this order so one change does not hide another.
- 1. Text size or zoom.
- 2. Line spacing.
- 3. Margins or crop.
- 4. Page color and contrast.
- 5. Scroll or paged movement.
- 6. Motion and animation preferences.
Test after each change
Read the same paragraph for a few minutes.
If the page becomes harder to follow, undo the last change before adding another.
Keep profiles simple
If your reader supports saved profiles, one daytime and one night profile are enough for many people.
Too many profiles can make choosing a setup slower than reading.
Use the file type as a guide
Reflowable ebooks benefit from text controls. Fixed PDFs often benefit more from crop, zoom, and orientation.
Do not force EPUB-style settings onto a page that must keep its original layout.
