Step by Step Tutorial: Making Font Bigger on iPhone

Before we dive into the steps, it’s important to understand that increasing the font size on your iPhone will affect most apps that support Dynamic Type, which includes most of Apple’s native apps and a variety of third-party apps.

Step 1: Access Settings

From your iPhone’s home screen, tap on the Settings app to open it.

This is where all your device’s configurable options reside. Think of it as the control center for your iPhone.

Step 2: Go to Display & Brightness

Scroll down and tap on Display & Brightness.

This section controls how content is displayed on your screen, including brightness, text size, and boldness.

Step 3: Tap on Text Size

In the Display & Brightness menu, tap on Text Size.

You’ll see a slider that you can drag to adjust the text size to your preference.

Step 4: Adjust Text Size

Drag the slider to adjust the font size. You’ll see a preview above the slider that shows how text will look at the selected size.

Keep in mind that not all apps will respond to this change immediately. Some might require a restart.

Step 5: For Larger Text Sizes, Tap Accessibility

If you need the text to be larger than what’s available in the Text Size settings, go back to the main Settings menu and tap Accessibility.

Accessibility features are designed to make your iPhone more user-friendly if you have certain physical or cognitive challenges.

Step 6: Select Display & Text Size

Within Accessibility, you’ll find Display & Text Size. Tap on it to access more options.

This menu offers more intense adjustments for visibility, including the option for larger text sizes.

Step 7: Tap on Larger Text

This option will allow you to enable larger accessibility sizes.

You’ll find another slider here, similar to the one in Text Size, but with a larger range.

Step 8: Enable Larger Accessibility Sizes

Toggle on Larger Accessibility Sizes to access the full range of text sizes.

Now, you can adjust the slider here to find the perfect text size for your needs.


Improved ReadabilityLarger font sizes make text easier to read, which is particularly beneficial for those with visual impairments or those who simply prefer bigger text.
Increased AccessibilityBy providing the ability to change font sizes, iPhones become more accessible to a wider range of users, promoting inclusivity.
Personalized User ExperienceUsers can tailor their device to their personal comfort, making their iPhone more enjoyable to use.


Limited App SupportNot all apps support Dynamic Type, so some third-party apps may not respond to these changes, leading to an inconsistent experience.
Screen SpaceLarger text takes up more space on the screen, which means less content will be visible at once, requiring more scrolling.
Interface DisruptionSome apps and interfaces may not handle larger text well, leading to awkward or cut-off visuals.

Additional Information

When we’re talking about making the font bigger on an iPhone, it’s not just about readability. It’s also about comfort and personal preference. Some people might find that a slightly larger font reduces eye strain during long periods of use. Others might be using their iPhone for presentations and need the text to be visible from a distance. It’s all about customization and making sure your iPhone works for you, not the other way around.

Another tip is to pair larger text with the Bold Text feature, also found in the Display & Brightness settings. This makes the text heavier and even easier to read. Also, keep in mind that if you’re using your iPhone in landscape mode, the increased font size might not play as nicely with the horizontal layout. You might need to experiment with different sizes to find the perfect balance.

Don’t forget about other accessibility features that can complement the larger text, like VoiceOver, which reads out loud the text on your screen, or Zoom, which magnifies the entire screen or just parts of it. These features can collectively create an iPhone experience that is tailored to your senses and needs.
