iOS 17 Tutorial: How to Change Font Size on iPhone

Before we dive into the step-by-step guide, let’s quickly discuss what you’ll achieve by following these instructions. Adjusting the font size on your iPhone can make the text easier to read and reduce eye strain. It’s a simple process that can significantly enhance your user experience.

Step 1: Open Settings

Open the ‘Settings’ app on your iPhone.

The ‘Settings’ app is typically found on your home screen and is represented by a gear icon. If you can’t find it, you can swipe down on your home screen and use the search bar to locate it.

Step 2: Access Display & Brightness

Scroll down and tap on ‘Display & Brightness.’

This section of your settings is where you can modify how things look on your screen, including the text size.

Step 3: Tap on Text Size

In the ‘Display & Brightness’ menu, select ‘Text Size.’

This will take you to a new screen where you can adjust the font size.

Step 4: Adjust the Font Size Slider

Drag the slider to adjust the font size to your preferred setting.

As you move the slider, you’ll see the font size change in real-time, so you can decide exactly how big or small you want your text to be.

After completing these steps, your iPhone will immediately apply the new font size setting across apps and features that support Dynamic Type. This includes most of Apple’s built-in apps and many third-party apps.

Tips for Changing Font Size on iPhone

  • Keep in mind that not all apps support Dynamic Type, so some may not reflect your font size changes.
  • If you need even larger text, there’s an ‘Accessibility’ feature called ‘Larger Text’ that offers additional sizes.
  • Remember that increasing the font size may mean more scrolling in apps with a lot of text.
  • If you share your device with others, consider their font size preferences before making changes.
  • You can always go back and readjust the font size if you find that your initial choice wasn’t quite right.
