Dyslexia-friendly ebook reading: the settings that actually help (fonts alone aren’t enough)

Ebooks are actually the ideal format for dyslexic readers, because unlike paper, every one of these factors is adjustable. Here’s what to adjust, why, and how to set it up on Android.

1. Spacing does more heavy lifting than the font

Crowded text is the enemy. Three settings matter more than the typeface itself:

• Letter and word spacing — extra space reduces visual crowding, the effect where letters seem to merge or swap.
• Line spacing — generous leading (1.5+) makes it harder to slip to the wrong line.
• Shorter lines — wider margins mean your eyes travel less and lose their place less often.

2. Colour and contrast: softer is often better

Pure black text on a bright white screen maximizes glare. Many dyslexic readers report less strain with a sepia or soft-tinted background, or light text on a dark background at night. There’s no single “correct” colour — the right answer is whichever tint makes the text stop shimmering for you, which is why being able to switch quickly matters.

3. Audio support: read with your ears and eyes together

For many people this is the biggest unlock. Text-to-speech with synchronized highlighting — where each sentence lights up as it’s spoken — lets your ears carry decoding while your eyes track along. That reduces fatigue and keeps comprehension high on long reading sessions. Look for a reader where narration is a built-in, first-class feature rather than a plugin.

4. One tap, not twenty settings

The paradox of customization: the readers with the most settings are often the most overwhelming to set up. A good app ships a ready-made dyslexia profile you can toggle with one tap, then fine-tune from there.

Setting this up in Lectern

We built Lectern with a one-tap Dyslexia reading profile: OpenDyslexic (optional — switch to the serif, sans-serif or monospace face instead), widened letter/line/paragraph spacing, and calmer background colours, applied together. From there you can tweak every element individually, including font weight and hyphenation.

And because Lectern doubles as an audiobook player, any book can be read aloud with natural offline AI voices while each sentence is highlighted — no separate TTS app, no cloud account, no subscription. Words you struggle with can be tapped for an offline dictionary definition and saved to a spaced-repetition vocabulary trainer.

Lectern is a one-time €2.49 on Google Play — no ads, no account, and nothing about your reading is tracked.
