Writer’s Guide for Dyslexic-Friendly Documents

When letters appear to jump, swirl, or blur together, the cognitive load required just to decode the text leaves little room for comprehension. This guide is designed to help writers, educators, and corporate professionals create formal documents that are truly accessible. By following these principles, you aren’t just helping dyslexic readers; you are creating a better, more readable experience for everyone.

1. Typography and Font Selection: The Foundation of Legibility

The first hurdle a reader faces is the typeface. For a dyslexic individual, certain fonts can cause letters to mirror or rotate.

Choose Sans-Serif over Serif

Serif fonts (like Times New Roman or Garamond) have small “feet” or decorative strokes at the ends of letters. While these are traditional, they add visual “noise.” Sans-serif fonts (like Arial, Verdana, Tahoma, or Calibri) offer cleaner, more distinct shapes that are significantly easier to process.

Seek Letter Distinctiveness

Avoid fonts where letters are carbon copies of one another. In many fonts, a lowercase ‘b’ is simply a flipped ‘d’. This is a recipe for confusion. Look for fonts where letter shapes are unique. Specialty fonts like Open Dyslexic or Dyslexie are specifically engineered with “weighted” bottoms to give letters a sense of “gravity,” helping to prevent the brain from rotating them.

Size and Weight Matter

• Font Size: Never go below 11pt. For maximum accessibility, 12pt to 14pt is the “sweet spot” for body text.
• Weight: Use a regular or slightly bold weight. Avoid “light” or “thin” fonts, as the thin lines can disappear against the background.
• Emphasis: Use bold for emphasis. Avoid italics and underlining, as these styles can make the letters appear to lean or run together, creating a “blurred” effect.

2. Spacing: Giving the Text Room to Breathe

Visual crowding is a major barrier to reading. When letters or lines are too close together, they can physically appear to merge.

• Letter Spacing (Tracking): Increase the space between individual letters slightly. This prevents them from “clumping.”
• Line Spacing (Leading): This is perhaps the most crucial adjustment. Use 1.5 or double line spacing. This extra vertical room helps the eye track from the end of one line to the start of the next without “line skipping.”
• Word Spacing: Ensure gaps between words are consistent. This leads us to one of the most important rules of accessible design: Alignment.

3. Layout and Design: Creating a Predictable Path

The way text sits on a page dictates the “flow” of the reader’s eye. If the layout is unpredictable, the reader spends more energy navigating the page than absorbing the content.

The Case for Left-Alignment

Always left-align your text (also known as “ragged-right”). This creates a consistent vertical anchor on the left side of the page, making it easy for the eye to return to the start of a new line.

Crucial Tip: Never use “Justified” text. While it creates neat blocks on both sides, it does so by creating uneven gaps between words. These gaps form “rivers of white” that run vertically through the text, which can be incredibly distracting and disorienting for those with dyslexia.

Structure and Hierarchy

Use a clear hierarchy of headings and subheadings.

1. Headings should be significantly larger and bold.
2. Numbering systems (1.0, 1.1, 1.2) provide a roadmap for the reader.
3. White Space: Don’t be afraid of empty space. Generous margins and “breathing room” around text blocks reduce visual clutter and help the reader focus.

4. Language and Sentence Structure: Reducing Cognitive Load

Accessibility isn’t just about how the words look; it’s about how they are processed.

Keep it Direct

Long, rambling sentences with multiple clauses are difficult for the working memory to hold. Aim for a Subject-Verb-Object structure. Instead of saying, “The decision, which was made by the board after many hours of deliberation, was finalized,” say, “The board deliberated for hours and finalized the decision.”

Use the Active Voice

The active voice is more “front-loaded” and easier to follow. It tells the reader who is doing what immediately.

• Passive: The report was finished by the team.
• Active: The team finished the report.

Break it Down

Use bullet points and numbered lists whenever possible. They break up dense information into “snackable” pieces. Additionally, keep your paragraphs short—one main idea per paragraph is the golden rule.

5. Colour and Contrast: Softening the Blow

For many, the high contrast of pure black text on a stark white background causes “glare,” leading to headaches and blurred vision. This is often referred to as Visual Stress.

• Avoid Bright White: Use an off-white, cream, or light grey background. This reduces the “dazzle” effect.
• Text Color: Use very dark grey or dark blue text instead of “stark” black (e.g., #333333).
• Digital Options: If you are sharing a digital document (like a PDF or Word file), remind readers that they can change the background colour in their settings to suit their needs.

6. Could You or a Colleague Be Dyslexic?

Many people struggle with reading and writing for years without realizing that their difficulties have a name. Dyslexia is often undiagnosed in adults, leading to unnecessary frustration in the workplace or classroom.

If you find that you frequently lose your place while reading, struggle with spelling despite high intelligence, or feel exhausted after reading a single page, the first step is clarity. Getting tested with a professional dyslexia screening test can provide the answers and support you need to thrive.

Providers such as The Indigo Dyslexia Centre offer comprehensive screenings. Identifying your specific learning profile is not about a label; it is about unlocking the right tools and strategies—like the ones in this guide—to help you succeed.

Conclusion

Producing a dyslexic-friendly document is an act of inclusion. By prioritizing clarity, consistency, and generous white space, you remove the invisible barriers that hold readers back. These principles don’t just help those with dyslexia; they improve the reading experience for people with ADHD, visual impairments, or those reading in their second language. Remember: Accessibility is simply good design.
