Do you want to change your iPhone’s font settings? You’ll be able to adjust your font by making it bigger, smaller, or bolder. However, if you want to change your system font to a different font entirely, you won’t be able to do so without jailbreaking your iPhone. This guide will teach you how to adjust your iPhone’s system font via settings and by jailbreaking your iPhone.

Before you start: Ensure your iPhone is updated and backed up.

Warning: Jailbreaking your iPhone will void your warranty and may violate your terms of use.

How to adjust font settings on your iPhone

This section will detail the steps to modify your iPhone’s font settings through the device’s settings and via jailbreaking.

  • Understand the limitations. As per your iPhone’s built-in settings, you can decrease or increase text size and bold (or un-bold) text.
  • Open your iPhone’s Settings. Tap the Settings app icon, which resembles a set of gears on a grey box.
  • Scroll down and tap Display & Brightness. This will show your display settings, including text size.
  • Tap Text Size. It’s towards the bottom of the screen. This will open a new page with a slider.
  • Drag the slider to adjust the text size. You can drag it left to make the text smaller or right to make the text bigger than the default size.
  • Tap the Back button. It’s in the top-left corner of the screen. Doing so will save your changes; you’ll see your chosen text size applied to the Settings app immediately.

How to jailbreak your iPhone for custom fonts

Changing your font settings on the iPhone can enhance your personalized experience, making text easier to read and more visually appealing.
