The quick recommendations
The best e-reader for a dyslexic reader is the one that lets them adjust the settings they actually use. A specialist font alone should not decide a purchase.
- Best dedicated device for visible layout controls: Kobo Clara or Kobo Libra Colour. Kobo documents OpenDyslexic support plus font size, line spacing, margins and justification controls.
- Best for the largest book ecosystem: Kindle Paperwhite. Current Kindles offer font and layout choices, themes, warm light on Paperwhite models and accessibility features including VoiceView. Feature availability can depend on the book and device.
- Best no-cost first step: install the Kindle or Kobo app on a phone or tablet you already own. Apps can offer more screen-colour flexibility and text-to-speech, although an LCD or OLED screen is different from E Ink.
- Best for articles and websites: use browser reading controls such as Dyslexly, because an e-reader is mainly designed for books.
There is no device proven to improve dyslexia. Treat this as an accessibility-feature comparison and test before buying.
Side-by-side comparison
| Option | Useful reading controls | Best for | Main trade-off |
|---|---|---|---|
| Kindle Paperwhite, 12th generation | Font and layout settings, themes, warm light, dark mode, VoiceView | Readers invested in Amazon's Kindle library | Exact controls can vary by book format and model |
| Kobo Clara BW or Clara Colour | OpenDyslexic, font size, line spacing, margins, justification, adjustable light | A compact dedicated reader with direct layout controls | Six-inch display is smaller for readers who need very large text |
| Kobo Libra Colour | Same core Kobo controls, seven-inch screen, page-turn buttons, colour display | Larger controls, annotation and illustrated books | More expensive; colour E Ink is less crisp than black-and-white text mode |
| Kindle app | OpenDyslexic, sizes, spacing, margins, several page colours and supported read-aloud tools | Testing Kindle controls without buying a device | Backlit phone or tablet screen; notifications can distract |
| Kobo app | Font and layout controls plus screen themes | Testing Kobo and reading on an existing device | App options are not always identical to Kobo e-reader options |
Prices change frequently, so compare current retailer prices rather than treating any figure in an old guide as permanent.
Kindle Paperwhite: best for the Kindle ecosystem
Amazon's current Kindle Paperwhite generation has a seven-inch display, adjustable warm light, dark mode, waterproofing and long battery life. Kindle readers allow users to change fonts, size, boldness, line and paragraph spacing, margins, orientation, alignment and reading themes.
Amazon explicitly lists OpenDyslexic in the Kindle apps. On dedicated Kindle devices, the available font list and accessibility features can vary with the model, software version and book, so confirm the exact device in a shop or during the returns period if that font is essential.
VoiceView provides screen-reader support on compatible Kindle devices. Amazon also offers Assistive Reader on supported content and devices, with text-to-speech and follow-along highlighting. Not every publisher or file enables every feature.
Choose a Kindle if your books are already in the Amazon ecosystem and warm light, waterproofing and battery life matter more than extensive visual experimentation.
Kobo Clara and Libra: best for explicit font controls
Kobo's own help documentation explains how to select OpenDyslexic on its e-readers. It also documents controls for font face, size, line spacing, margins and justification.
The Kobo Clara family is compact and usually the lower-cost route into Kobo's current range. Kobo Clara Colour adds a colour E Ink display, while Clara BW prioritises black-and-white reading.
Kobo Libra Colour has a larger seven-inch screen, physical page-turn buttons, waterproofing, ComfortLight PRO, dark mode and 32 GB of storage. Its colour display can be useful for covers, comics and annotations, but colour content is shown at a lower pixel density than black-and-white text. Do not pay extra for colour if you mainly read novels.
Choose Kobo if changing font and layout on the dedicated device is central to your decision, or if you prefer Kobo's store and library integrations.
A phone or tablet may be the better first test
Before spending money, install the free reading app for the ecosystem you are considering. Amazon's Kindle apps explicitly support OpenDyslexic, font sizes, spacing, margins and several page colours. They also offer accessibility tools on eligible content.
A tablet can provide a larger screen, stronger zoom and more colour options. The drawbacks are a backlit display, shorter battery life and more distractions. Try reducing brightness, using a warm display setting and disabling notifications during reading.
If the app's controls solve the problem, you may not need a separate device.
The book format matters
Adjustable text works best in reflowable ebooks. A scanned page is essentially a picture, and a fixed-layout PDF may not let the device change its font, line spacing or margins.
Kobo states that its usual font and layout adjustments are unavailable for PDFs. Kindle behaviour also depends on how a document was created or converted. If you read textbooks, worksheets or research papers, load a representative file onto the device before committing to it.
For websites and web-based study materials, a browser tool is normally more direct. Dyslexly's free extension can change font, spacing and overlay settings on web pages and can read selected text aloud.
A 15-minute try-before-buy checklist
Take this list to a shop or use it during the returns window:
- Open a normal chapter, not only the device's home screen.
- Increase the font until you can read without leaning closer.
- Compare a familiar sans-serif font with OpenDyslexic if it is available.
- Adjust line spacing and margins separately.
- Read for five minutes with the front light at a comfortable level.
- Try the same page in daylight and a dim room.
- Test page turns, menus, dictionary lookup and any read-aloud feature you need.
- Load one of your own PDFs or documents.
- Check the cost and availability of the books you actually read.
A device with a long feature list is a poor choice if its menus are difficult for the intended reader.
Our buying verdict
For most buyers, compare a current Kindle Paperwhite with a Kobo Clara first. Pick Kindle for its ecosystem and polished all-round hardware; pick Kobo when its documented OpenDyslexic and layout controls fit your reading routine. Consider Kobo Libra Colour when the larger screen, buttons, colour or annotation support justify the extra cost.
The safest recommendation is to test the free apps, then handle the two shortlisted devices with a real book and a real document before buying.

Frequently Asked Questions
Does Kindle have OpenDyslexic? Amazon explicitly lists OpenDyslexic in its Kindle reading apps. Font availability on a dedicated Kindle can depend on the device, software and book, so check the exact model if it is essential.
Does Kobo have OpenDyslexic? Yes. Kobo publishes instructions for choosing OpenDyslexic on its e-readers. Kobo also lets readers change font size, line spacing, margins and justification in supported ebook formats.
Is a colour e-reader better for dyslexia? Not automatically. Colour E Ink may help with illustrated material or personal preferences, but it does not make a device a dyslexia treatment. Compare text clarity, lighting and layout controls first.
Can an e-reader change the font in a PDF? Often not. Fixed-layout and scanned PDFs may prevent font, spacing and margin changes. Test one of your own files before buying a device mainly for PDF reading.
