Why does my ebook text feel cramped on small screens?

Readers want text that stays clear across every device without causing eye strain. Professional book interior typography solves this by pairing measured spacing with typefaces designed for digital rendering. When your layout respects how eyes track lines on a tablet or phone, reading feels effortless.

What makes interior typography work for digital reading?

This approach focuses on how letters, words, and paragraphs behave inside a reflowable ebook file. It works best for long-form content where readers spend twenty minutes or more per session. Clean type selection and consistent vertical rhythm keep attention on the content, not on formatting glitches. You apply it during the final formatting stage, after editing and before export.

How should I adjust type for different devices and genres?

Your choices should shift based on where and how your audience reads. Phone readers need slightly larger base sizes and narrower margins to avoid excessive scrolling. Tablet and e-ink users handle traditional serif faces well, while backlit screens often favor low-contrast sans serifs. Nonfiction with heavy data benefits from clear hierarchy and wider line spacing, whereas fiction reads smoothly with modest indentation and tighter tracking. If you publish across multiple platforms, test how your font scales when readers adjust their device settings.

Which formatting mistakes break readability, and how do I fix them?

Start with a base size between 1em and 1.125em and let the reading app handle absolute scaling. Set line height to 1.5 or 1.6 for comfortable tracking, and keep paragraph spacing consistent instead of mixing indents and blank lines. A common mistake is locking font sizes in pixels, which breaks user preferences and creates cramped text on small displays. Another frequent error is pairing two decorative faces that compete for attention. Avoid full justification on narrow screens, as it creates uneven word gaps that disrupt reading rhythm. Fix these issues by switching to relative units, removing fixed width constraints, and sticking to one primary typeface with a single complementary style for headings. You can preview changes directly in Calibre, Kindle Previewer, or Apple Books before publishing. For deeper font selection strategies, the notes on choosing screen-optimized families break down weight and x-height considerations.

What should I check before exporting the final file?

Run through these steps before you export your final file. Verify that body text uses relative sizing and responds to reader adjustments. Check line spacing, margin balance, and heading hierarchy on a phone, tablet, and e-ink device. Replace any pixel-locked values and remove conflicting font declarations. Confirm that chapter titles use semantic heading tags rather than bolded paragraphs, since semantic markup ensures navigation menus parse your structure correctly. If you need a quick reference for spacing ratios and margin setups, the layout examples in this typography reference show exact CSS values. For readers who primarily browse on browsers or web apps, the guidelines on screen-friendly font behavior help you adjust rendering hints and fallback stacks. Export, test one more time, and publish when the text flows without forcing the eye to work.
