Reading with Dyslexia: Evidence-Based Strategies for Students

Dyslexia · 4 min read · Updated 2026-07-28

Key points

• Dyslexia is a phonological-processing difference — not low intelligence or effort — affecting roughly 1 in 5 people.
• Structured literacy is the gold-standard instruction; no app or font replaces it.
• Accommodations with real support: increased letter spacing, reduced visual crowding, and text-to-speech.
• Specialty dyslexia fonts have mixed evidence — try them as preference, but letter and line spacing matter more.

Dyslexia is common, well-studied, and widely misunderstood. It is not a problem of intelligence, effort, or "reading backwards." At its core it's a difference in phonological processing — the ability to connect the sounds of language to the letters that represent them — and it affects roughly 1 in 5 people to some degree (Shaywitz & Shaywitz, 2020).

That distinction matters, because it separates two kinds of help that often get lumped together: instruction that builds reading skill over time, and accommodations that make reading more accessible right now. You need both, and it helps to know which is which.

What is the most effective way to teach reading with dyslexia?

The most robustly supported approach for teaching dyslexic readers is structured literacy — explicit, systematic instruction in the building blocks of reading: phonological awareness, sound–symbol relationships, syllables, morphology, and how they combine into words and meaning.

A systematic review and meta-analysis spanning forty years of intervention research found that multicomponent programs providing explicit, systematic instruction in these foundational skills — while also focusing on meaning — produce significant positive effects on reading (Hall et al., 2023). The International Dyslexia Association reaches the same conclusion, and notes that this kind of instruction helps all readers, not only those with dyslexia.

The honest caveat: structured literacy is a teaching method, usually delivered by a trained specialist over time. No app or font replaces it. If you or your child has dyslexia, evidence-based instruction is the foundation — everything below supports it, rather than substituting for it.

What accommodations actually help dyslexic readers?

Alongside instruction, several changes to how text is presented have research support for making reading more accessible in the moment.

Increase letter spacing

Crowded letters are harder for dyslexic readers to tell apart. Simply increasing the space between letters has been shown to improve both reading speed and accuracy for dyslexic children — without any training, just by changing the spacing (Zorzi et al., 2012). It's one of the easiest, best-supported adjustments available, and most reading tools let you set it.

Reduce visual crowding

The same principle scales up to the whole page. Surrounding clutter measurably slows letter recognition — an effect called visual crowding (Pelli & Tillman, 2008). Reading one line or short section at a time, on a clean surface, removes most of the surrounding noise and lets each word land on its own.

Let text-to-speech carry some of the load

Decoding is the effortful part of dyslexic reading, and it competes for the same mental resources you need to understand what you're reading. Text-to-speech offloads some of the decoding: you hear the words while you see them, following the highlighted line. This dual-channel approach can free up attention for comprehension, and for many students it's the difference between finishing a reading and abandoning it. It's an accommodation, not a fix for the underlying difficulty — but it's a legitimate and powerful one.

Consider the font, with realistic expectations

Dyslexia-oriented fonts (like OpenDyslexic) and generous line spacing are popular accommodations. Many readers genuinely prefer them and find them more comfortable, which matters — comfort keeps you reading. The research on specialty fonts specifically is mixed, so treat them as a personal-preference option worth trying rather than a guaranteed boost. Letter spacing and line spacing have stronger evidence than the letterforms themselves.

Strategies that stack with everything above

A few habits help every reader and cost nothing:

• Read in small sections. Smaller chunks mean less to hold in working memory and less crowding on screen.
• Space it out. Several short sessions beat one long one for retention — a well-established effect (Cepeda et al., 2006) — and long unbroken reading is especially tiring when decoding is effortful.
• Check understanding actively. After a section, recall or quiz yourself on the main points instead of re-reading. Retrieval builds durable memory more efficiently than review (Roediger & Karpicke, 2006) — valuable when every re-read costs real effort.

The takeaway

For dyslexia, the evidence points to a clear division of labor: structured literacy instruction to build the skill, and accommodations — letter spacing, reduced crowding, text-to-speech — to make reading accessible while that skill develops. Neither replaces the other.

Evanreads is built on the accommodation side of that line. It gives you adjustable letter and line spacing, a dyslexia-friendly font option, line-by-line focus that cuts visual crowding, and text-to-speech that follows along as you read — the presentation changes with the strongest support, in one place. It won't replace good instruction, and it doesn't claim to. What it can do is make the reading in front of you right now easier to get through.
