Accessibility options can make it easier to read your phone

When I was home visiting my mom on vacation, I took the time to upgrade her iPhone’s operating system.

After upgrading from iOS 15 to iOS 16, she noticed that the default text size had reverted to a smaller size. Mom, like many people, prefers her text to be slightly larger for easier reading.

She didn’t remember how to increase the text size, so I showed her how to do it.

Since this setting is rarely changed, I thought this would be a good reminder.

The size of text displayed in apps on mobile phones is controlled by display system settings.

On your iPhone, open your phone’s settings,[ディスプレイと明るさ]Scroll down to

In the center of the display settings window you will see an option for Text Size and a button to turn on Bold Text.

When you open the Text Size settings, you’ll see a slider to change the size of text in apps that support Dynamic Type. Dynamic Type is used by most system settings and apps from Apple and other developers.

Note that changing the setting here will change the size of the text across the phone, but some apps may not display the text as expected.

After changing the text size on my iPhone, apps like Mail and Messages displayed large text, but not WeatherBug or Amazon.

If you need your text to be even bigger, there is another text size option called “Large Text” within the iOS Accessibility System Preferences that allows you to display very large text.

Accessibility settings also have an option to stretch the entire screen. This is useful for some apps that don’t allow dynamic text resizing.

When you zoom in on the screen, you can scroll the screen with three fingers.

Android users also have a font size control in their display system settings.

Android OS also includes another accessibility system setting with the option to stretch the entire screen.

Accessibility options in both phone operating systems let you change the display, such as inverting colors, increasing contrast, and using color filters.

If you’re having trouble seeing or reading your phone’s screen, check your phone’s system settings for accessibility options.
