Dyslexic readers are not one uniform group. Clear typography, sensible spacing, text-to-speech and user control can help, but preference and context matter.
Move past the idea of a magic font
Conversations about dyslexia-friendly design often collapse into one question: which font should we use? Typeface matters, but it is only one part of a reading experience.
Line length, spacing, contrast, paragraph structure and plain language all affect how much work a page asks of the reader. The British Dyslexia Association’s style guide recommends readable sans-serif type, adequate size and spacing, left alignment and uncluttered presentation. It also recognises text-to-speech as a useful option.
Let sound and print support each other
Hearing a sentence can reduce the decoding work involved in getting from printed forms to meaning. Seeing the word at the same time preserves spelling, punctuation and location on the page.
Some readers may want to follow every word. Others may listen while looking away, then return for details. The interface should make both patterns equally valid.
Dyslexia-friendly design is not about labelling one presentation as correct. It is about removing the lock on personal preference.
Make the written page comfortable before adding tools
Text-to-speech should not be used as an excuse for tiny or crowded copy. Start with a page that is readable on its own: meaningful headings, a manageable column width, generous line height and enough contrast.
- Avoid long passages in all capitals or italics.
- Keep paragraphs short enough to scan.
- Use bullets for genuinely list-like information.
- Prefer descriptive links over repeated “click here” labels.
- Do not fully justify body text, which can create uneven gaps between words.
Control should remain with the reader
Voice, rate and highlighting are personal. A faster voice may help one reader maintain momentum and overwhelm another. A bright highlight may provide a strong anchor or become distracting.
Defaults should be sensible, but controls should remain easy to find. The product should remember choices rather than ask the same questions every time.
Use careful language about benefit
A reading extension can offer access and convenience. It should not claim to treat dyslexia or promise improved outcomes for every person. The honest position is stronger: this is one flexible tool that may make some forms of digital reading easier.
That modesty belongs in the product as well as the marketing. Let people try it, adjust it and decide for themselves.
