Quick answer
For EPUB, start with a text size that lets you read without squinting, medium margins, normal line spacing, and either paged reading or continuous scroll. Change one setting at a time.
There is no single best setting for every phone. Use the same real page while you test changes.
A good starting setup
Use this as a starting point, not a rule.
- Text size: one comfortable step above the app default if the default feels small.
- Line spacing: normal or slightly open.
- Margins: medium; reduce them only on a small screen.
- Page color: light paper during the day, darker page at night if you prefer it.
- Movement: paged for clear stops, continuous scroll for uninterrupted flow.
How to know a setting is helping
Read the same page for five to ten minutes. If you stop noticing the interface and can follow the text easily, the setup is probably good enough.
If you keep losing your place, the problem may be line width, page movement, or zoom rather than font size.
Common settings mistakes
Do not change text size, line spacing, page color, and movement at the same time. You will not know which change helped.
Do not copy another person’s exact font size. Screen size and eyesight differ.
When to reset to defaults
If the page starts looking cramped, oddly spaced, or hard to follow, reset the reading appearance and make one change again.
Keep the original file unchanged. Reader settings should change how you see the file, not rewrite the book.
If the first fix does not work
Try another known-good epub files example. If the second one works, the first file or item is probably the problem. If both fail in the same way, the app, phone, or setting is more likely.
