The two ways to make your iPhone keyboard bigger

You can make your iPhone keyboard larger in two ways: by turning on larger keyboard text in accessibility settings, or by using the one-handed keyboard that shrinks the layout to one side of the screen. The first option makes the keys and letters bigger but keeps the keyboard in its normal position. The second option keeps the standard key size but moves everything to the left or right edge, leaving empty space on the other side — useful if you type with one hand.

Neither option requires restarting your phone or downloading anything. Both are built into iOS and take less than a minute to turn on. You can switch between them or turn them off at any time.

Key Takeaways

  • Larger keyboard text is found in Settings > Accessibility > Keyboard, and makes the letters and numbers on your keys visibly bigger.
  • One-handed keyboard mode moves the entire keyboard to the left or right side of your screen and is turned on by holding the globe icon (or space bar) during typing.
  • You can use both settings at the same time — larger text plus one-handed mode — if you need both changes.
  • These settings affect only the standard iPhone keyboard; third-party keyboard apps have their own size controls in their individual settings.

How to enable larger keyboard text

Open the Settings app and tap Accessibility. Scroll down and tap Keyboard. Toggle on Larger Keyboard. The change takes effect when ready — the next time you open the keyboard, the text on the keys will be noticeably larger.

This setting affects the standard Apple keyboard only. If you use a third-party keyboard app (like Gboard or SwiftKey), you will need to adjust the size in that app's own settings, not in the iPhone accessibility menu. You can find those settings by opening the keyboard app itself, then looking for a settings or preferences option within the app.

How to use one-handed keyboard mode

One-handed mode shrinks the keyboard to one side of the screen. To turn it on, open any app where you can type — Messages, Notes, Mail, or any text field. Tap and hold the globe icon at the bottom left of the keyboard (or if you don't have a globe icon, hold the space bar). A menu will appear with three keyboard layout options: a left-aligned keyboard, a right-aligned keyboard, and the standard full-width keyboard. Tap the left or right option.

The keyboard will move to that side and stay there until you switch it back. If you want to return to the full-width keyboard, hold the globe icon or space bar again and tap the center option. You can switch between left, right, and full-width mode as many times as you want while typing.

Combining larger text with one-handed mode

You can turn on larger keyboard text and use one-handed mode at the same time. If you do, the keyboard will be both bigger and positioned to one side of the screen. This combination is useful if you need the text larger for visibility but also want the keyboard out of the way of your thumb.

To use both: first enable larger keyboard text in Settings > Accessibility > Keyboard. Then, during typing, hold the globe icon or space bar and choose left or right alignment. Both changes will explore together.

What to do if the keyboard size options don't appear

If you don't see a globe icon or the option to hold the space bar, your iPhone may not have one-handed keyboard enabled in settings. Go to Settings > Accessibility > Keyboard and make sure One Handed Keyboard is toggled on. If it is already on and you still don't see the globe icon, restart your iPhone by turning it off and back on.

If you are using a third-party keyboard app, the one-handed mode may not be available — it depends on whether that app supports the feature. Check the app's settings or help section to see if it has a similar option. Some third-party keyboards have their own side-alignment features under different names.

Keyboard size settings for different iPhone models

The steps above work on all current iPhone models running iOS 16 or later. If you have an older iPhone running iOS 15 or earlier, the menu locations may be slightly different, but the Accessibility > Keyboard section will still exist. The one-handed keyboard feature has been available since iOS 11, so even older iPhones support it.

If you are unsure which iOS version you have, go to Settings > General > About and look at the "Software Version" line. If you are running an older version and want to check for updates, go to Settings > General > Software Update.

Resetting keyboard settings to default

If you want to turn off larger keyboard text, go back to Settings > Accessibility > Keyboard and toggle off Larger Keyboard. To exit one-handed mode, hold the globe icon or space bar during typing and tap the center option to return to full-width. Both changes take effect when ready.

If you have changed multiple settings and want to start over, you can reset all accessibility settings to their defaults. Go to Settings > General > Reset and tap Reset Accessibility Settings. This will turn off larger keyboard text, one-handed mode, and any other accessibility changes you have made — but it will not affect your apps, photos, or other data.

Frequently Asked Questions

Does changing keyboard size affect how I type or my autocorrect?

No. Larger keyboard text and one-handed mode only change how the keyboard looks and where it sits on your screen. Your typing speed, autocorrect, and predictive text work exactly the same way. The keys respond the same — they are just visually bigger or positioned differently.

Can I make the keyboard even bigger than the "Larger Keyboard" setting?

The "Larger Keyboard" toggle in accessibility settings is the only built-in option for text size. If you need the keyboard even bigger, you can combine it with one-handed mode to reduce the number of keys on screen, which makes each key take up more space. Some third-party keyboard apps also offer additional size options in their own settings.

Will one-handed keyboard mode work with my external Bluetooth keyboard?

No. One-handed mode only affects the on-screen keyboard. If you connect a physical Bluetooth keyboard to your iPhone, the on-screen keyboard will not appear, and one-handed mode will not explore. The physical keyboard will work normally.

What if I accidentally turn on one-handed mode and can't find how to turn it off?

Hold the globe icon or space bar again and tap the center option to return to the full-width keyboard. If you cannot see the globe icon, make sure one-handed keyboard is enabled in Settings > Accessibility > Keyboard. If it is off, the globe icon will not appear during typing.

Do these settings work on iPad too?

Yes. Both larger keyboard text and one-handed keyboard mode are available on iPad running iOS 16 or later. The steps are the same: go to Settings > Accessibility > Keyboard to enable larger text, and hold the globe icon during typing to switch to one-handed mode.
