iPhone Settings for Dyslexia: A Complete Guide
If you're dyslexic, your iPhone can be frustrating to use. Text is hard to parse, notifications pile up, and reading emails or messages takes longer than it should. The good news is that Apple has built several accessibility features into iOS specifically designed to help people with dyslexia and reading difficulties.
This guide walks you through the best iPhone settings for dyslexia, covering everything from font choices to reading aids. You'll learn exactly where to find each setting and how to use them effectively.
Use Larger, Clearer Fonts
Small text makes dyslexia worse. iOS lets you increase font size across nearly every app on your phone.
Go to Settings > Display & Brightness > Text Size. Drag the slider all the way to the right to enlarge text system-wide. This works in Mail, Messages, Notes, Safari, and most third-party apps.
If you want even more control, use Settings > Accessibility > Display & Text Size > Larger Accessibility Sizes. This option lets you choose even bigger sizes (up to 310% of normal). It's particularly useful if you have a visual impairment alongside dyslexia.
Font choice matters too. Arial, Verdana, and sans-serif fonts are generally easier for dyslexic readers than serif fonts (which have little decorative strokes). Unfortunately, iOS doesn't offer a system-wide font change to a dyslexia-friendly typeface. However, third-party solutions like Dyslexly can enhance your reading experience with OpenDyslexic font and other reading assistance tools across your entire browser on iPhone and iPad.
Enable Bold Text and High Contrast
Bold, high-contrast text reduces visual stress and makes letters clearer. Go to Settings > Accessibility > Display & Text Size > Toggle "Bold Text" on. Your phone will restart, and all text will display in a bolder weight.
Next, turn on "Increase Contrast" in the same menu. This darkens text and increases the colour difference between foreground and background, making text pop off the screen.
If regular contrast isn't quite enough, enable "Increase Contrast" and then also toggle on "Reduce Transparency". This removes the glass-like blur effect from iOS menus, making everything sharper and more defined.
Turn On Smart Invert
Bright white backgrounds can cause visual fatigue and make reading harder, especially if you have dyslexia alongside light sensitivity. Smart Invert flips your colour scheme to dark backgrounds with light text, but it's intelligent enough not to invert images.
Find it at Settings > Accessibility > Display & Text Size > Smart Invert. Toggle it on, and your entire phone display inverts. You can toggle it off and on whenever you need a break from bright screens.
Many dyslexic users find that a dark mode dramatically improves their ability to focus and read for longer periods. If you prefer, you can also set your entire phone to Dark Mode: Settings > Display & Brightness > Dark.
Activate Speak Screen and Speaking Rate
Text-to-speech is one of the most powerful tools for dyslexic readers. iOS has two built-in options.
Speak Screen reads any text on your screen aloud. Enable it at Settings > Accessibility > Spoken Content > Speak Screen. Once on, you can select any text and tap "Speak" from the menu, or swipe down from the top of the screen with two fingers to speak the entire page.
Speak Selection does something similar: it reads selected text without you having to do anything special. Go to Settings > Accessibility > Spoken Content > Speak Selection and toggle it on.
You can also adjust the speaking rate in the same menu to slow down speech, making it easier to follow along. Start at a comfortable pace and increase speed as you adjust.
Use Reading Guides and Focus Features
Reading guides help you track your place on the page and reduce visual overload. Go to Settings > Accessibility > Display & Text Size > Reading Guide. Toggle this on, and a light-coloured bar will appear behind the line you're reading, moving as you scroll. This helps your eyes stay focused and reduces the chance of skipping lines.
For even more focus, enable Settings > Accessibility > Display & Text Size > Reduce Motion. This removes animated transitions and makes the interface feel calmer and less distracting.
If you're using Safari on your iPhone to browse the web, consider that many websites have poor readability for dyslexic users. Text sizing, colour contrast, and font choices often work against you. Browser-based tools can help here: Dyslexly offers features like colour overlays, word simplification, and reading guides that work specifically in your browser, complementing iOS's built-in accessibility tools beautifully.
Configure Notifications and Reduce Visual Clutter
Notifications create cognitive load and distraction. If you have dyslexia, too much visual information on your screen at once makes reading and concentration harder.
Go to Settings > Notifications and disable notifications for apps you don't urgently need. For critical apps like Messages or Mail, keep notifications on but customise them: turn off badge counts (the red circles with numbers), and disable lock screen notifications so you're not hit with alerts constantly.
You can also go to Settings > Focus and create a custom Focus mode for reading and work time. When active, this silences all notifications except from people you choose. Enable it while you're reading emails, documents, or anything requiring concentration.
Pair iOS Settings with Additional Tools
Apple's accessibility features are strong, but they work best alongside other tools. If you spend a lot of time reading on your iPhone or iPad, combining iOS settings with additional reading aids gives you the best result.
For instance, you might use Smart Invert for dark mode, increase your text size to 25%, and turn on Speak Screen. But if you're reading an article in Safari, Dyslexly adds word simplification, letter spacing, and a reading guide tailored for dyslexic users, taking your reading experience further.
The combination of iOS accessibility and browser-based tools creates a much more comfortable reading environment than either alone.
Frequently Asked Questions
Can I change the font on my iPhone to a dyslexia-friendly typeface? Apple doesn't offer system-wide font changes to dyslexia-friendly fonts like OpenDyslexic in iOS settings. However, you can increase font size, make text bold, and enable high contrast, all of which help. If you're reading in Safari, tools like Dyslexly can apply dyslexia-friendly fonts and reading aids directly in your browser.
What's the difference between Smart Invert and Dark Mode? Dark Mode is intentional design that applies dark colours across the whole interface. Smart Invert uses technology to invert your display while keeping images normal, which is useful for any app. Both help reduce eye strain for many dyslexic readers, so try each and see which feels better.
Will text-to-speech slow down my reading speed? Text-to-speech doesn't necessarily slow you down if you pair it with reading the text simultaneously. Many dyslexic users find that hearing and reading together improves comprehension and speed. Start slowly and adjust the speaking rate as you become more comfortable.
Can I enable multiple accessibility features at once? Absolutely. Combining larger text, bold formatting, high contrast, Smart Invert, and reading guides all at once is perfectly fine. Each adds its own benefit, and most users find that layering several features creates the most comfortable reading experience.
Do these iPhone settings work on older devices too? Most of these features work on iPhone models from the last 5-8 years, though the oldest devices may not support all options. Go to Settings > Accessibility to see which features your specific phone supports. Reading Guide and certain text formatting options require iOS 15 or later.
Conclusion
Your iPhone can be a powerful tool for managing dyslexia, not a source of frustration. By using larger fonts, bold text, high contrast, and text-to-speech together, you'll dramatically improve your reading comfort and speed. Spend time experimenting with each setting to find your ideal combination, and don't hesitate to enable multiple features at once. The goal is a reading experience that works for you, and iOS gives you many options to get there.
