How to change the font size in Android

Use of a smartphone is heavily text-centric.

To a visually impaired person, the modern miracle of a smartphone comes with acute challenges. Not the least of these is the fact that the use of the phone is heavily text-centric, and they are meant to be used on the go. To allow for quicker, more comfortable phone use by those with vision impairment, Android allows you to change the font size up or down from the default size. You can also turn on screen magnification, which lets you pinch-zoom in and out of your screen as if you were looking at a photograph. Both are easy to use and adjust if you know where to look. WE discuss how to change the font size in Android in this quick how to below.

Pro tip: In addition to changing the font size, there are some other accessibility features you might want to consider, including changing the font type to something easier to read. For more tips, check out our guide to the Android Accessibility Suite.

QUICK ANSWER

In your Settings menu, go to Accessibility > Text and display > Font size. Adjust the slider to the left to reduce the font, and to the right to increase it. Then back out of the page.

How to change the font size in Android

Start by opening your Settings menu. Then select Accessibility > Text and display > Font size. You will see a slider that will let you adjust the font size. Slide it to the left and right until the font is the size you are looking for. Then just back out of the page; there is no need to save the new setting.

How to change the display size in Android

This is a very similar process to changing your font size. Open the Settings app on your Android device and proceed to Accessibility > Text and display > Display size. You will see a similar slider as above, but for display size. Slide it back and forth until you have the setting you want, and then just back out of the menus.

How to turn it on

Once again, start in your Settings app and move through Accessibility > Magnification and tap on Magnification shortcut. Choose from one of the three options: Accessibility button, Hold volume keys, or Triple-tap screen. Of the three ways of turning on magnification, we recommend the button, because the triple-tap option will slow down your phone’s operation as single taps take longer, and holding down both volume buttons felt very awkward. When you back out of the menu to your home screen, you will see the accessibility button at the lower right of your screen.

Tap on the Accessibility button, and an orange rectangle will surround the active area of your screen.

Tapping anywhere within the rectangle will magnify the screen, centered on the point where you tapped. Tapping near the Calendar icon yields a magnified image. Dragging with two fingers will let you scroll around the page, and pinching with two fingers will increase or decrease the zoom level. To end the magnification, tap on the Accessibility button again.

How to use it

To magnify in a more temporary way, press the Accessibility button, then tap and hold anywhere on the screen. Now you can drag your finger around to change the area that is magnified. Just lift your finger off the screen to stop the magnification.
To have text magnified for you as you type, use the Magnify typing option. Go to Settings > Accessibility > Magnification to access this feature.

Things to remember about magnification

  • If you open or close an app while the screen is magnified, you will zoom out to full view. To magnify again, use your chosen magnification shortcut.
  • The maximum magnification is 8x.
  • The reason single taps take longer when you choose a triple-tap as your magnification shortcut is that the OS is waiting to see if the tap is part of a triple-tap.

FAQs

Almost, but not all. If you are still using an Android device running any version older than 9, the feature will not be available.

Quite a few. Among other features, you can opt for high-contrast text and color-corrected screens; use the TalkBack screen reader to describe what is on your screen and what command you just entered; turn on Voice Access to control your device with your voice; adjust the time given to take action at a prompt; and even let the Lookout feature give you audio notifications about your physical environment.
