Dyslexia Browser Settings That Help: A Practical Guide

Reading online can feel overwhelming when you're dyslexic. Websites are cluttered, text zips past in unfamiliar fonts, and colours blend together in ways that make focus nearly impossible. The good news? Your browser has built-in features and settings that can transform your reading experience, and many websites now support accessibility features designed specifically for people with dyslexia.

This guide walks you through the dyslexia browser settings that help, explains how to use them, and shows you how to get even more support when you need it.

Choose a Dyslexia-Friendly Font

The typeface you read in matters enormously. Standard fonts like Arial or Times New Roman can make letters scramble or blur together for dyslexic readers. Fonts like OpenDyslexic, Comic Sans, and Verdana are designed to make each letter distinct and memorable.

Most browsers let you change the default font in settings. Here's how:

For Chrome: Go to Settings > Appearance > Customise Fonts. Change both the Standard Font and Sans-serif Font to something more accessible.

For Firefox: Visit Preferences > Home > Fonts & Colours. Tick the box that says "Allow pages to choose their own fonts" only if you trust the website; otherwise, set a custom font.

For Safari: Open Preferences > Advanced > Style Sheet and select a dyslexia-friendly option if available.

Many readers find that installing Dyslexly as a browser extension gives them even finer control, allowing font changes on every website instantly without manual configuration.

Adjust Text Size and Spacing

Dyslexic readers often benefit from larger text and increased spacing between lines and words. Cramped text makes your eyes work harder to track from one letter to the next.

Most browsers have built-in zoom controls:

• Use Ctrl + plus sign (or Cmd + plus on Mac) to enlarge text
• Use Ctrl + minus to reduce it
• Press Ctrl + 0 to reset to default

For spacing within text, you have fewer options in standard browser settings, but some operating systems help here too. Windows has a built-in "ease of access" centre where you can increase font size system-wide. macOS offers similar controls in System Preferences > Accessibility > Display.

If you find yourself zooming constantly, browser extensions can do the work for you automatically, remembering your preferences across all sites.

Use High-Contrast Colour Schemes

Colour overlays and high-contrast settings reduce visual stress and make text pop off the page. Black text on white can cause glare and make letters seem to move or blur. Softer colour combinations, or inverted colour schemes, help many dyslexic readers concentrate for longer.

Chrome and Firefox both support colour filter extensions. You can also use your operating system's built-in tools:

Windows: Settings > Ease of Access > Display > Turn on colour filters. Choose from several high-contrast themes.

macOS: System Preferences > Accessibility > Display > Increase Contrast or Enable Grayscale.

Many websites now let you toggle a dark mode in their settings (often in the footer or account menu). Look for sun/moon icons or "accessibility" options when you visit a new site.

For comprehensive colour overlay support across every website, a dedicated accessibility tool offers more flexibility than standard browser settings alone, letting you apply soothing teal, cream, or grey overlays instantly.

Enable Text-to-Speech Features

Hearing text read aloud is transformative for many dyslexic readers. It combines visual and auditory input, helping your brain process information more easily. Some browsers and operating systems have built-in readers, though they're often limited.

Windows: Right-click any text and select "Read aloud" if available; this feature varies by browser.

macOS: System Preferences > Accessibility > Spoken Content > Select "Speak selection." This lets you highlight any text and hear it read aloud.

iOS and Android: Most devices have built-in screen readers (Voice Over on iOS, TalkBack on Android) that work across apps and browsers.

Browser-based solutions tend to offer better voice quality and more control over reading speed. If you visit /upgrade, you'll find tools that add professional-quality text-to-speech to websites where you need it most, syncing with visual text so you can follow along.

Reduce Visual Clutter and Line Focus

Websites are packed with sidebars, ads, notifications, and distractions. For dyslexic readers, visual noise makes concentration exhausting. Some browsers have "reader mode" built in, which strips away clutter and shows just the article text.

Chrome: Look for a reader icon (book symbol) in the address bar on supported articles.

Firefox: Click the reader icon when available (appears as a small book icon).

Safari: Tap the "Reader" button when viewing supported content.

These tools work well, but they only function on certain article pages. For broader coverage, line focus tools let you highlight just one or two lines at a time, hiding everything else. This keeps your eyes from bouncing around the page and helps you track where you are in the text.

Browser extensions designed for dyslexic readers often include both clutter-reduction and line-focus features, giving you consistent support across the entire web rather than on isolated pages.

Customise Cursor and Pointer Settings

A small or blurry cursor makes it hard to track your place on screen. If you lose the cursor frequently, browser settings can help.

Windows: Settings > Ease of Access > Cursor & Pointer. Increase cursor size and change the colour to something that contrasts with your background.

macOS: System Preferences > Accessibility > Display > Cursor. Increase cursor size here.

Some people also benefit from a magnified pointer that grows when they move the mouse slowly. These tools live in your operating system's accessibility settings, so they work across the entire browser and all websites.

Organise Your Browser for Success

Beyond settings, the way you organise your browser matters. Save frequently-visited sites to your bookmarks bar. Use folders to group related bookmarks. Clear your browser cache regularly so old versions of pages don't slow you down.

Consider bookmarking a single accessibility settings page where you keep links to the sites you use most. This reduces the cognitive load of remembering URLs and searching when you're already tired from reading.

Frequently Asked Questions

What's the best browser for people with dyslexia? Chrome and Firefox offer the most customisation through their settings and extension ecosystems. Safari works well if you're on Apple devices. The "best" browser is whichever one lets you access the tools and settings you need most; test a few and see what feels easiest.

Can I save my browser settings so they apply to every website? Partially. Your browser's built-in settings (font, colour filters, cursor size) apply to most sites automatically. However, individual website designs can override some settings. Browser extensions help here by forcing your preferences on top of website styles, ensuring consistency across the entire web.

Is it better to use browser settings or a dedicated accessibility extension? Browser settings are a great first step and are free. Extensions like Dyslexly go further because they combine multiple tools (fonts, colours, text-to-speech, line focus) into one place and apply them consistently to every website. Many people use both: system-wide settings for general preferences, and an extension for extra support when reading is hard.

Do all websites respect my browser's accessibility settings? Not always. Poorly designed websites use inline styles and fixed fonts that override your browser preferences. This is where extensions step in, forcing your preferred fonts and colours on top of any website's design. It's not perfect, but it works on most modern sites.

Will changing my browser settings slow down my computer? No. Accessibility settings typically have no impact on browser speed. Font changes, colour filters, and cursor adjustments are handled directly by your operating system and browser. Extensions use a small amount of memory, but modern computers handle this easily.
