You can make text larger and more readable on your iPhone or iPad, but you can also increase the size of the app icons, text labels, and user interface elements on your iPhone 6, 6 Plus, 6S, or 6S Plus so it's easier to use.

RELATED: How to Make Text Larger and More Readable on iPhone or iPad

By default, your iPhone's display resolution is in "Standard" mode. However, you can set it to "Zoomed" mode, which essentially makes your iPhone show the same size user interface as the next smallest iPhone model. For example, an iPhone 6S Plus in Zoomed mode will look like an iPhone 6S in Standard mode. Instead of seeing more content on the screen, the content will be larger, which is very useful if you have trouble seeing the items on your iPhone's screen. The image above shows the Standard mode of an iPhone 6S Plus on the left, and the Zoomed mode of the same iPhone on the right.

It doesn't just affect the home screen, either–the entire OS will show slightly bigger elements so they're easier to see.

To put your iPhone into Zoomed mode, tap the "Settings" icon on your Home screen.

On the Settings screen, tap "Display & Brightness".

Then, tap "View" on the Display & Brightness screen.

On the Display Zoom screen, tap "Zoomed".

The icons on the sample screen are enlarged to show what the zoomed display resolution will look like. To set this resolution, tap "Set".

A confirmation popup displays with the message that changing the display zoom will restart your iPhone. Tap "Use Zoomed" at the bottom of the screen to use the zoomed display.

Don't be alarmed at this point. The screen will go black for a bit and then return to the Display Zoom screen. The message claimed that your phone will restart, but you don't have to sign in to your phone again.

When you return to your Home screen, the icons and text labels will be larger, as will other text and elements on your phone.

One final catch: if you have an iPhone 6 Plus or 6S Plus, the Home screen will not change to landscape mode while you're in zoomed mode. You must go back to the standard display zoom to allow your phone's Home screen to automatically change to landscape mode when you rotate it.
