Dyslexia-friendly Windows 11 setup
Windows 11 ships with more accessibility controls than most users ever find. For someone with dyslexia, the right combination of display settings, font rendering tweaks, colour adjustments, and a couple of browser extensions can turn a tiring reading experience into a manageable one. This guide walks through the full stack, from system-level settings to the browser tools that cover what Windows cannot.
Quick orientation: Windows handles text size, contrast, and colour at the OS level. Chrome — and extensions like LexiFont — handle font choice and spacing on every website you visit. Both layers matter, and they don't duplicate each other. You need both.
Start with Display settings
The single highest-impact change most dyslexic Windows users can make is increasing text size without scaling the entire interface. Go to Settings > Accessibility > Text size and drag the slider up. Windows 11 separates "text size" from "display scale" — text size enlarges only text, leaving icons, toolbars, and layout intact. Most users with dyslexia find 120–130% a comfortable starting point. The text preview at the bottom of the page updates in real time so you can calibrate by eye.
Display scale (Settings > System > Display > Scale) is a different control. It enlarges everything proportionally and is better for low vision than for dyslexia specifically. At 125% or 150% scale, the Windows interface stays readable on a high-DPI monitor, which reduces squinting that compounds reading fatigue. If you're on a 1080p laptop screen at close range, 125% is often a sensible baseline.
ClearType tuning
ClearType is Windows's sub-pixel rendering engine. It smooths text by using the red, green, and blue sub-pixels of an LCD panel to create the illusion of sharper edges. On most monitors it makes text significantly more legible — but the default calibration is set for an "average" monitor and viewer, which may not match your display or your eyes.
To re-calibrate ClearType: press Win + S, type ClearType, and open "Adjust ClearType text." Work through the five screens, picking whichever sample looks sharpest to you each time. On IPS monitors the middle-to-upper options usually win; on older TN panels you often prefer lower contrast. The whole process takes under two minutes and the improvement can be striking if the default was badly mismatched to your screen.
Note: ClearType is only relevant for LCD panels. If you're using an OLED laptop or a 4K monitor at native resolution, Windows will already be rendering text at full per-pixel sharpness and ClearType has little effect. On those displays, fractional scaling (Settings > Display > Scale, set to 125% or 150%) matters more than ClearType.
Colour filters and Night Light
Windows 11 ships with colour filters under Settings > Accessibility > Colour filters. These include greyscale, inverted, and several colour-blindness corrections. For dyslexia specifically, the most relevant options are:
Inverted: flips the colour scheme so white backgrounds become black. Some people with dyslexia find that white backgrounds create a glare that makes text swim. Full inversion is crude — it turns images into negatives — but it's worth a five-minute trial if glare has been a persistent irritant. A more refined approach is dark mode in the browser, which inverts only web content and preserves image colours.
Night Light (Settings > System > Display > Night Light) shifts the screen toward warmer amber tones by reducing blue-light output. This is not the same as reducing contrast — warmth and contrast are independent dimensions. Many readers find that a warm screen (around 4000 K, which is roughly the default "warm" setting) reduces the sharp whiteness that makes long reads uncomfortable. This is especially true in the evenings but worth trying during daytime if you work under fluorescent lighting, which adds its own blue-spectrum flicker. See our full piece on visual stress and screen tints for the research behind this.
A third option is to adjust the background colour of specific applications rather than the whole screen. In Microsoft Word, for instance, you can set the page background to a cream or pale yellow through Page Layout > Page Colour. The evidence on background colours for dyslexia suggests that off-white and pale yellow tend to reduce visual stress more reliably than blue or grey backgrounds, even if the effect size varies by individual.
Windows Narrator and Read Aloud
Narrator is Windows's built-in screen reader. For dyslexic users who process spoken text more efficiently than written text, Narrator can work as a reading aid even though it was designed for blind or low-vision users. Press Win + Ctrl + Enter to start it. The default voice (Microsoft David or Microsoft Zira, depending on your region) is intelligible but robotic; under Settings > Accessibility > Narrator > Narrator's voice you can switch to Microsoft Neural voices like Aria or Guy, which sound substantially more natural at higher speeds.
For web reading specifically, Microsoft Edge's Read Aloud feature (Ctrl + Shift + U in Edge, or the "Read aloud" button in Edge's toolbar) is more refined than Narrator for long articles. It highlights each word as it speaks and can be controlled by the Immersive Reader view, which strips navigation and ads from pages and presents only the article text in a clean, adjustable layout. If you primarily read in Chrome, the approach is different — see our guide on text-to-speech in Chrome for the extension options that work on any site.
Immersive Reader in Edge vs Chrome with extensions
Edge's Immersive Reader deserves a dedicated mention. Press F9 on any news or blog page in Edge and it strips the page to body text, then lets you adjust font size, line spacing, column width, background colour, and syllable-highlighting. The syllable feature is particularly useful for decoding unfamiliar words. If you read a lot of news, documentation, or long-form articles, Immersive Reader can do a lot of the work without needing any extensions.
The limitation of Immersive Reader is that it works only in Edge and only on pages with detectable article content. It won't activate on web apps, dashboards, email interfaces, or heavily dynamic sites. Chrome doesn't have a native equivalent, which is where browser extensions fill the gap.
For Chrome users — which covers most Windows users, given Chrome's market share — the core missing piece is font override. Chrome has a built-in font setting (Settings > Appearance > Customize fonts) but it only controls your default font, not the fonts that websites explicitly specify. Most sites override your default, so your setting has no effect. Extensions like LexiFont work differently: they inject a stylesheet that forces every site to use your chosen dyslexia-friendly font regardless of what the site requests. That's the gap they're filling.
Choosing a dyslexia-friendly font for the browser
The three fonts most consistently recommended for dyslexia on screen are OpenDyslexic (weighted-bottom letterforms designed to reduce b/d/p/q confusion), Lexend (generous letter spacing and simplified shapes, backed by readability research), and Atkinson Hyperlegible (high letter differentiation developed for low-vision readers, also effective for dyslexia).
OpenDyslexic is the most recognisable and has the most direct dyslexia-specific design intent. Lexend tends to read more naturally for people who find OpenDyslexic visually busy. Atkinson Hyperlegible sits between the two. The full comparison — including side-by-side reading samples — is in our piece on the best fonts for dyslexia in 2026.
None of these fonts is installed on Windows by default. LexiFont bundles all three and applies your choice across every site you visit. The free tier covers OpenDyslexic; LexiFont Pro unlocks Lexend, Atkinson Hyperlegible, Comic Neue, and controls for font size, line height, and letter spacing — all adjustable per-site if you want different settings for news versus work tools.
Spacing: the thing most guides skip
Font choice gets most of the attention, but spacing adjustments often matter as much or more. The relevant dimensions are line height (the vertical gap between lines), letter spacing (the gap between characters within a word), and word spacing (the gap between words). Research on readers with dyslexia consistently finds that generous line height — around 1.5× the font size at minimum, 1.8× for longer reads — reduces regressive eye movements more reliably than font choice alone.
Windows itself has no per-application spacing control for web content. You can adjust document spacing in Word (Format > Paragraph > Line spacing) and Outlook (a similar path), but the web is out of reach from the OS level. This is another gap that browser extensions fill. Our guide on line spacing and letter spacing for dyslexia covers the research and the practical thresholds worth trying.
Putting it together: a practical Windows 11 baseline
Rather than adjusting everything at once, a sensible order of operations is:
Step 1 — Text size. Settings > Accessibility > Text size. Set to 120–130%. This is the cheapest win and affects every app on the machine.
Step 2 — ClearType. Run the calibration wizard. Takes two minutes and sharpens text at the rendering level without touching any layout.
Step 3 — Night Light or colour filter. Enable Night Light at a warmth you find comfortable (somewhere between "Balanced" and "Warm" is a reasonable starting point for most people). If bright white backgrounds specifically bother you, try the Colour filter inverted mode for one reading session.
Step 4 — Browser font. Install LexiFont in Chrome, pick OpenDyslexic or Lexend, and read one long article. You'll know within a few minutes whether the font change is helping. If the shapes of letters felt like the problem, OpenDyslexic will likely feel like relief. If spacing and flow were the issue, Lexend often feels more natural.
Step 5 — Spacing. Use LexiFont's spacing controls (Pro tier) to push line height to 1.6–1.8 and letter spacing to 0.05–0.1em. These are subtle changes individually but compound with the font change.
Step 6 — TTS for long reads. Install a Chrome TTS extension or use Edge's Read Aloud for articles you need to process deeply. Listening and reading simultaneously — called "dual coding" — reduces the working memory load that makes long reads tiring for many people with dyslexia. Our overview of dyslexia and working memory explains why this helps more than it might sound.
One caveat about High Contrast mode: Settings > Accessibility > Contrast themes offers four high-contrast presets. These are designed for low vision and some users with dyslexia find them helpful, particularly the "Aquatic" and "Desert" themes which use non-white backgrounds. However, high-contrast modes often break web layouts and are sometimes incompatible with font-override extensions. If you want a warm or tinted background specifically for web reading, it's usually more reliable to handle that at the browser or extension level rather than via a system-wide contrast theme.
Windows vs Chromebook: a quick comparison
If you're deciding between a Windows machine and a Chromebook for a student or child with dyslexia, the accessibility profiles differ meaningfully. Chromebooks have tighter integration between the OS and Chrome, a simpler accessibility interface with fewer settings to navigate, and a lower cost baseline. Windows has more powerful native tools (Immersive Reader, Narrator's neural voices, Word's built-in spacing controls) and broader software compatibility for any assistive apps your school or employer uses. See our separate guide on dyslexia-friendly reading on a Chromebook for the Chromebook-specific walkthrough. The browser layer — Chrome with a font extension — is identical on both platforms, which makes the transition between them straightforward.
Reading specific apps on Windows
A few Windows-specific reading contexts that often need individual attention:
Microsoft Word: set the body font to Lexend or Atkinson Hyperlegible via Home > Font, increase line spacing to 1.5 or 2.0, and turn on the Read Aloud feature under the Review tab. Word also ships with an Immersive Reader mode under the View tab — it's the same engine as Edge's Immersive Reader and worth using for reviewing long documents. Our dedicated guide covers all the Microsoft Word dyslexia settings in detail.
Outlook: set the reading pane font to a dyslexia-friendly option under File > Options > Mail > Stationery and Fonts. This changes the display font for incoming mail. Using Chrome and web Outlook instead of the Outlook desktop app also gives you access to browser-level font overrides.
Microsoft Teams: Teams has limited font control natively, but reading it through Chrome (teams.microsoft.com) instead of the desktop app gives you full browser-extension support. Our guide on reading Microsoft Teams with dyslexia covers both routes.
