Use display and text size preferences on your iPhone, iPad and iPod touch

With iOS accessibility features for the display, you can enlarge your text, make it bold, increase contrast, apply colour filters, use Smart Invert, control auto-brightness and more.

Turn on Invert Colours

If you benefit from viewing items against a dark background, you can use Invert Colours to change how content is displayed on your screen. 

To use Invert Colours, open the Settings app, then tap Accessibility > Display & Text Size.

Smart Invert

Smart Invert reverses the colours on the display, except for images, media and some apps that use dark colour styles.

Classic Invert

Classic Invert reverses all colours on the display.

Turn on Colour Filters

If you have colour blindness or other vision challenges, you can use Colour Filters to help you differentiate between colours. Colour Filters can change the look of things, like pictures and videos, so you may want to use it only when needed.

Open the Settings app, then tap Accessibility > Display & Text Size > Colour Filters. You'll see three examples of colour spaces to help you select an option that fits your needs. Swipe left or right on the examples to find a filter that works best for you.

From left to right, this example shows pencils in a rainbow of colours, starting with red and yellow, and ending with purple and brown.

This example shows three columns of colour intensity.

This example shows vertical lines on a variable colour background for colour deficiencies. Choose the filter that shows the entire line.

Choose a filter

When you turn on Colour Filters, you can choose from four preset filters:

  • Greyscale
  • Red/Green for Protanopia
  • Green/Red for Deuteranopia
  • Blue/Yellow for Tritanopia

Adjust colour intensity

You can adjust the intensity of any of the Colour Filters to fit your needs. Use the Intensity slider to customise a filter that's more intense or less intense.

Adjust Colour Tint

If you have colour or light sensitivity, tap Colour Tint to change the hue of the entire display on your iPhone, iPad or iPod Touch. Use the sliders to adjust your display's hue and the intensity of the effect.

More display accommodations

In addition to inverting colours and applying filters, you can also find these accommodations on the Display & Text Size screen:

  • Bold Text: Makes the text in your device's user interface bold.
  • Larger Text: Tap this, then turn on Larger Accessibility Sizes. Then you can use the slider to adjust your preferred reading size.
  • Button Shapes: Adds shapes to buttons — for example, an underline beneath Back buttons.
  • On/Off Labels: Adds On/Off labels on preference screens.
  • Reduce Transparency: Improves contrast by reducing transparency and blurs on some backgrounds.
  • Increase Contrast: Improves colour contrast between app foreground and background colours.
  • Differentiate Without Colour: Replaces user interface items that rely solely on colour to convey information.
  • Reduce White Point: Reduces the intensity of bright colours.

Limit Frame Rate

If you have an iPad Pro (10.5-inch) or iPad Pro 12.9-inch (2nd generation), you can set the maximum frame rate of your display to 60 frames per second. Open the Settings app. Tap Accessibility > Motion, then turn on Limit Frame Rate.
