[Updated Guide] How to Change Font on iPhone (Font Size & Style & Color)?

Part 1: How to Change Font Size on iPhone

If you find the text on your iPhone too small to read comfortably, you can follow the methods below to increase the font size.

Method 1: Adjust Text Size in Settings

1. Open "Settings" on your iPhone and tap "Display & Brightness".
2. Select "Text Size" to access the font size controls.
3. Drag the slider left or right to make the text smaller or larger.

The new font size will be applied system-wide in apps that support Dynamic Type.

Method 2: Use Accessibility Settings for Larger Text

If you need text that is larger than the standard options:

1. Open "Settings" and go to "Accessibility".
2. Tap "Display & Text Size", then select "Larger Text".
3. Turn on "Larger Accessibility Sizes" and adjust the slider to your preferred size.

This option is especially helpful for users who need extra-large text for better readability.

Part 2: How to Change Font Style on iPhone

While iOS limits system-wide font changes, there are still several practical ways to customize font styles on your iPhone using built-in features and third-party tools.

Method 1: Use Built-in Font Options (Limited Customization)

iPhone does not support changing the system font across the entire device. However, some apps, such as Mail, Pages, and Notes, allow you to select different font styles within the app itself.

1. Open an app that supports font formatting, such as Pages or Mail.
2. Tap the text formatting icon (usually shown as "Aa").
3. Choose a font from the available options, such as Helvetica, Arial, or Times New Roman.

Method 2: Install Custom Fonts on iPhone (iOS 13 or Later)

How to change font style on iPhone without app? Starting with iOS 13, Apple allows users to install custom fonts through apps available on the App Store. These fonts can be used in apps that support font selection.

1. Download a font management app, such as iFont or AnyFont, from the App Store. (iPhone Cannot Connect to App Store?)
2. Follow the on-screen instructions in the app to install your preferred fonts.
3. Go to "Settings > General > Fonts" to view and manage the installed fonts, then use them in supported apps like Pages or Microsoft Word.

Method 3: Use Third-Party Keyboards for Stylized Fonts

Third-party font keyboards can generate decorative or stylized text for use in messaging and social apps, though they do not change the system font.

1. Install a font keyboard app, such as Fonts or FancyKey, from the App Store.
2. Enable the keyboard by going to "Settings > General > Keyboard > Keyboards".
3. Switch to the new keyboard when typing to apply different font styles in messages or posts.

Part 3: How to Change Font Color on iPhone

Unlike font size or style, iOS does not provide a universal setting to change font color across the entire system. However, you can still modify text color in certain apps and situations, mainly when editing text or creating documents.

Method 1: Change Font Color in Supported Apps

Some apps, such as Notes, Pages, Mail, and third-party document editors, allow you to change text color while editing content.

1. Open an app that supports text formatting, such as Notes or Pages.
2. Select the text you want to edit, then tap the formatting option (usually shown as "Aa").
3. Choose a color from the available palette to apply it to the selected text.

Method 2: Use Markup Tools to Apply Text Color

Markup tools allow you to add colored text or annotations to screenshots, images, or PDFs on your iPhone.

1. Open a photo, screenshot, or document and tap "Edit" or "Markup". (How to Edit Photos?)
2. Select the text tool and choose a preferred color from the color picker.
3. Add or edit text using the selected color, then save your changes.

Method 3: Adjust System Display Settings (Visual Effect Only)

Although this does not change font color directly, certain display and accessibility settings can affect how text colors appear on your screen.

1. Go to "Settings > Accessibility > Display & Text Size".
2. Enable options such as "Increase Contrast" or "Color Filters".
3. Adjust the settings to improve text visibility based on your preference.

Part 4: Use iOS Assistant for Better Text Management

Although iOS offers basic font and text customization options, it provides very limited control when it comes to exporting, backing up, or printing text content such as Notes and Messages. Many users need a more efficient way to manage large amounts of text, preserve original formatting, or prepare content for editing and printing on a computer. In this case, a professional desktop tool like Coolmuster iOS Assistant becomes a practical supplement when system font customization is not enough.

Part 5: FAQs About Changing Font on iPhone

Q1: Can I change the system font on iPhone?

No. iOS does not allow users to change the system-wide font. You can only adjust font size, bold text, or use custom fonts in supported apps.

Q2: Why can't I change font style in all apps?

Font style support depends on each app's design. Many apps follow Apple's default system font and do not allow custom fonts.

Q3: Are third-party font apps safe?

Most font apps from the App Store are safe if downloaded from reputable developers. However, they usually work only in specific apps and not system-wide.

Q4: How do I restore the default font on iPhone?

You can remove installed fonts from "Settings > General > Fonts", disable third-party keyboards, or reset display settings to return to default fonts.

Conclusion

Changing fonts on an iPhone comes with clear limitations, but you still have several practical options depending on your needs. If your goal is better readability, adjusting font size and using Accessibility features is the safest and most effective choice. For visual personalization, third-party font apps and app-specific font settings can help enhance messages and documents.

If you need to organize, export, or print text while preserving its original format, tools like Coolmuster iOS Assistant provide a reliable desktop solution. Choose the method that best matches how you use your iPhone.
