Bilingual readers with dyslexia - font choice across two alphabets

Most advice about dyslexia-friendly fonts quietly assumes one language - and that language is almost always English. If you read in two languages every day, especially two that use different scripts, the standard recipe breaks in small but exhausting ways. This piece is for bilingual readers with dyslexia: what changes when a second language enters the picture, what stays the same, and the practical font choices that actually hold up.

Why bilingualism changes the equation

Dyslexia is not a single deficit. It expresses differently in different orthographies. Italian, Spanish and Finnish are shallow orthographies where each letter maps to a sound with near-perfect consistency. English is a deep orthography where the same letter sequence can be pronounced half a dozen different ways. A dyslexic reader who is fluent in both Italian and English will often report that reading Italian is noticeably easier - not because they are better at Italian, but because the writing system itself is less ambiguous.

That asymmetry matters for typography. The visual confusions that hurt most in English (homographs, silent letters, b/d/p/q rotation in a sea of irregular spellings) are not the same as the visual confusions that hurt most in, say, Russian, where soft and hard signs sit close to other letters, or in Arabic, where the shape of a letter changes depending on its position in the word. A font that solves a Latin-alphabet problem may do nothing for the script you spend the other half of your day in.

Two common cases

Bilingual readers tend to fall into one of two situations, and the right typography depends on which one you are in.

Case 1: both languages share the Latin alphabet

English and Italian. Spanish and English. German and French. Portuguese and Italian. Two languages that share most letters but differ in rhythm, accent marks, and frequency of certain digraphs (ll, ñ, sc, gn, gh, ç).

Here, your main job is to pick a font that handles accented characters well and keeps letter shapes unambiguous regardless of which language is on screen. Some dyslexia-friendly fonts were designed primarily with English in mind, and their support for accents and diacritics is uneven. OpenDyslexic, for example, has full Latin Extended coverage but the accents sit a little heavy on some characters - readable, but visually noisy if your text is dense with accents (French, Portuguese, Vietnamese). Lexend and Atkinson Hyperlegible have cleaner accent handling and are generally a better default for Romance languages.

Case 2: the two languages use different scripts

English plus Russian. English plus Greek. English plus Arabic. Spanish plus Mandarin. One language is in the Latin alphabet, the other in a completely different writing system. This case is much harder, because most "dyslexia fonts" only cover Latin script. You end up using two different fonts depending on which language is on screen, and switching between them adds its own cognitive cost.

The cross-script rule of thumb: for the non-Latin language, do not look for a "dyslexia font" - they mostly do not exist for Cyrillic, Arabic, Greek or CJK at the same quality as the Latin ones. Look instead for a high-legibility default that ships with the operating system or Google Fonts, then control the size, spacing, weight and background aggressively. The settings around the font matter more than the font itself when no dyslexia-specific option exists.

What stays the same in any language

Some things help regardless of which script you are reading:

  • Larger text. A point or two above the system default. See best font size for dyslexic adults - the principle generalises across alphabets.
  • Generous line height. 1.5 to 1.7 of the font size. Dense lines hurt every reader, dyslexic or not, and they hurt more in scripts you read slightly slower in (which is usually your second language).
  • Off-white background. Cream, pale blue, soft grey. See background colours for dyslexia - the colour science is independent of language.
  • Avoid italics for body text. Italics in any script are harder to parse with dyslexia. Use bold for emphasis, not italic.
  • Avoid all-caps. Word-shape is one of the cues you rely on to recognise words. All-caps removes it, which hurts dyslexic readers in every alphabet that has case.

Font picks by script

Latin (English, Italian, Spanish, French, German, Portuguese, Dutch, Polish, Czech, Hungarian, Vietnamese, Turkish, etc.)

This is the well-trodden ground. Your three serious options are OpenDyslexic, Lexend, and Atkinson Hyperlegible. The trade-offs are covered in detail in best fonts for dyslexia in 2026 and OpenDyslexic vs Lexend. For multilingual Latin reading, Atkinson Hyperlegible is the most diplomatic default - its accent handling is the cleanest, and it does not impose a strong visual personality the way OpenDyslexic does.

Cyrillic (Russian, Ukrainian, Bulgarian, Serbian, Belarusian, Macedonian)

There is no widely-used Cyrillic equivalent of OpenDyslexic. The closest pragmatic options are PT Sans and PT Serif (commissioned for the Russian public sector and explicitly tuned for legibility), and Noto Sans in its Cyrillic cuts. Cyrillic letters like ш, щ, и, н, п, и and й are visually similar in many display fonts; PT Sans was designed with that confusability in mind. Pair it with the size and spacing recipe above and you have a workable equivalent of an English Lexend setup.

Greek

Greek dyslexia research is small but real, and the consistent finding is that the modern monotonic orthography is easier than the older polytonic version. For fonts, GFS Didot (designed at the Greek Font Society) and Noto Sans Greek both work well at size 16-18 with generous spacing. Avoid Greek fonts with tightly-coupled ligatures - they look elegant but blur letter boundaries.

Arabic

Arabic is genuinely difficult because each letter has up to four positional forms (isolated, initial, medial, final), and many fonts use elaborate ligatures that compress letter shapes into composite glyphs. For dyslexic readers in Arabic, look for "simplified" Arabic fonts with minimal ligatures and clear baseline alignment. Noto Naskh Arabic and Amiri at larger sizes are the most legible defaults. There is ongoing work on dyslexia-friendly Arabic typography (the AbjadType project, among others) but nothing yet that has the install base of OpenDyslexic in English.

CJK (Chinese, Japanese, Korean)

In CJK scripts, dyslexia presents differently and font advice tilts toward stroke contrast and structural clarity rather than letter-shape distinction. For Chinese, Source Han Sans at heavier weights (Medium or Bold) is more legible than thin display faces. For Japanese, prefer Hiragino Kaku Gothic or Yu Gothic, and avoid mixing hiragana, katakana and kanji in a font that does not weight them consistently. Korean readers can find Hangul-specific guidance in the work of the LG dyslexia research group; Noto Sans KR is the safe modern default.

The switching cost

Bilingual readers report a specific complaint that monolingual ones rarely mention: the moment of switching. Going from a paragraph of English to a paragraph of Russian, or from Italian to Arabic, requires the brain to reset its visual decoder. For dyslexic readers, that reset is slower and more effortful. There is no font that fixes this - the cost is cognitive, not typographic - but you can soften it.

Two practical tactics:

  • Match the rhythm. If you are reading a bilingual page (a translated article, a language-learning document, a dual-language children's book), try to pick fonts of similar weight and x-height in both scripts. A heavy Cyrillic next to a thin Latin makes the switch feel like falling off a cliff.
  • Match the colour and background. The non-font settings - background colour, line height, paragraph width - should stay constant across both scripts. The font may change; the environment should not.

A practical setup in Chrome

Most bilingual reading happens in the browser. Here is the setup that holds up across languages:

  1. Pick your Latin-script font from Atkinson Hyperlegible, Lexend, OpenDyslexic, or Comic Neue. Apply it to every site with LexiFont - one click, no per-site fiddling.
  2. For pages in your non-Latin language, let the site keep its native font (LexiFont leaves non-Latin glyphs alone by default unless you override). Instead, push size and line-height up using the LexiFont sliders.
  3. Set a comfortable background colour once. It carries across both languages, every site, every session.
  4. Use reader mode for long articles in either language. Chrome's reader mode strips visual clutter and lets your font choice do the work. See reader mode vs reading extensions for when to pick which.
  5. If you frequently read PDFs in two languages, the PDF workflow is the same - extract to HTML, then style.

What the research actually says about bilingual dyslexia

The strongest finding in the bilingual dyslexia literature is the script-dependent expression of difficulty: the same person can show clear dyslexic symptoms in one of their languages and almost none in the other, depending on the orthographic depth. Bilingual children with Italian and English, for instance, are routinely identified as dyslexic later in Italian than in English, because Italian's regularity hides the underlying decoding difficulty. This has practical consequences. If you read fluently in your shallow-orthography language and struggle in your deep-orthography one, you are not "bad at" the second language - the second language is genuinely visually harder, and font choice in that language is more load-bearing.

The second consistent finding is that visual interventions transfer poorly across scripts. A reader who benefits from OpenDyslexic in English does not automatically benefit from a Cyrillic equivalent, because the shape confusions OpenDyslexic targets (b/d/p/q rotation) do not directly map onto Cyrillic confusions (ш/щ, и/н, п/л). Treat each script as its own problem; do not assume the English fix carries over.

If you read in three or more languages

Polyglot readers with dyslexia exist and tend to have very specific preferences. The pattern that emerges from informal community reports: keep one constant default across all your Latin-script reading (almost always Atkinson Hyperlegible or Lexend - their multilingual coverage and neutrality wins), and treat each non-Latin script as a separate setup. Trying to harmonise four fonts across four scripts is more cognitively expensive than just learning to recognise each one in its native, legible default.

A note on language-learning content

If you are using a second language to learn, not just to read fluently, font choice tilts further toward maximum clarity. Bionic Reading-style bolding (see Bionic Reading vs OpenDyslexic) is actively bad in a language you are still learning - the bolded fragments do not align with the morpheme boundaries you are trying to internalise. Plain text, slightly larger size, and a high-legibility font is the most honest setup. Apps like Anki and Duolingo let you change the typeface; do so.

Trying this in practice

The cleanest way to test all of this is to take the same article in both your languages - a Wikipedia page works well, since translations are easy to find - and read each version in the font setup proposed above. Note where your eye stalls, where you re-read, and where you feel comfortable. The right setup is usually obvious within ten minutes per language.
