To make emojis bigger on iPhone 13, you have two Apple-documented options: send a single emoji by itself in Messages for a larger display, or use the system-wide Zoom accessibility feature to magnify all on-screen content. Neither method involves a dedicated emoji-size slider, but both are built into iOS.
Make emojis bigger on iPhone 13 in Messages
In the Messages app, sending one emoji by itself makes it appear significantly larger than normal. This works only when the message contains exactly one emoji, sending two or more emojis, or an emoji with text, does not trigger the larger display.
- Open the Messages app and select a conversation.
- Tap the text input field to bring up the keyboard.
- Switch to the emoji keyboard and select a single emoji.
- Tap the send button. The emoji will appear much larger in the conversation bubble.
This behavior is documented in recent Apple-related coverage for current iPhone software. There is no setting, slider, or button in Messages to adjust emoji size, the single-emoji rule is the only way to get the larger appearance within the app. You can also touch and hold an emoji in the Messages text field, then use the Markup feature to select a larger size before sending.
Use the Zoom feature to magnify all emojis and screen content
Apple’s Zoom feature magnifies the entire display, making emojis and custom keyboards appear larger across all apps. It is not an emoji-specific setting, but a screen magnifier that works system-wide. You can also adjust emoji size indirectly by going to Settings > Display & Brightness > Text Size, which changes emoji size across the device. Additionally, you can install a third-party keyboard app from the App Store that offers adjustable emoji sizes.
- Go to Settings > Accessibility > Zoom.
- Turn on Zoom.
- For quicker access, go to Settings > Accessibility > Accessibility Shortcut and select Zoom.
- Use double-tap the screen with three fingers to turn Zoom on or off. You can also use the Accessibility Shortcut if configured.
Apple documents two magnification modes: Full Screen Zoom magnifies the entire screen, while Window Zoom magnifies only a portion of the display. You can adjust the magnification level by double-tapping with three fingers and sliding your fingers up or down. This feature is available on iPhone and iPad and is the built-in way to enlarge all on-screen content, including emojis.
