How To Change The Font Size On Your Android Phone’s Keyboard
If you've migrated to a new Android phone or switched to a different keyboard app on your existing phone, you might find that the keyboard is too small for your liking.
You can change your keyboard’s height by opening an app that uses the keyboard, then tapping the gear icon to open Settings. Next, tap Preferences and select Keyboard Height.
If you use the keyboard app Swiftkey, you change the size in a similar fashion. Tap the three dots on the keyboard, tap Modes, then tap Resize and change the size to your liking.
If your keyboard doesn’t have a size option, you can try tweaking your phone’s display size. Open the Settings app, search for Display Size, and drag the size slider to the right.
