If text, icons, or controls are hard to see on your iPhone, change the setting that matches the problem: use Larger Text or Bold Text for readability, Display Zoom for a larger interface, and contrast or button options when controls blend into the screen. Change one setting at a time, then switch it back or adjust it if the result is less comfortable.
How do I make text easier to read on my iPhone?
Open Settings > Accessibility > Display & Text Size > Larger Text, then move the slider to the size you want. Turn on Larger Accessibility Sizes on that screen if you need sizes beyond the standard range. You can also turn on Bold Text in Display & Text Size to make lettering heavier. Apple’s iPhone text readability guide also describes adding a Text Size control to Control Center, which lets you change text size while using an app.
Try the size adjustment first, then add bolding if thin lettering remains difficult to distinguish. Some apps may not support every display adjustment in the same way.
How do I make icons and controls larger?
Use Display Zoom when the whole interface—including icons, buttons, and text—feels too small. In Settings, look for Display Zoom and choose the larger view, then apply it as prompted. Apple’s guides place display controls under different labels, including Display & Brightness and Appearance; if the path on your iPhone differs, search Settings for “Display Zoom.” Apple explains the feature in its text and display guide and display settings guide.

How do I make buttons and controls easier to distinguish?
If buttons disappear into the page or are hard to identify as tappable, open Settings > Accessibility > Display & Text Size and turn on Show Borders. This adds borders around onscreen controls and buttons. Where available, try Button Shapes as another way to make button affordances clearer.

What should I change when text or controls blend into the background?
For poor separation between foreground content and the background, try Increase Contrast or Reduce Transparency under Settings > Accessibility > Display & Text Size. Increase Contrast strengthens the difference between foreground and background. Reduce Transparency makes translucent backgrounds opaque. Apple’s display preferences overview describes both settings.
If your iPhone offers Liquid Glass appearance choices
On supported current software, Apple describes Tinted as higher in contrast and opacity than Clear. Apple’s display settings guide notes that Reduced Transparency or Increased Contrast must be off to change the Liquid Glass look. If the appearance control is unavailable, use the accessibility contrast and transparency settings instead.

What if an app uses color alone to communicate meaning?
Turn on Differentiate Without Color to add alternatives for information otherwise conveyed only by color. For switches, On/Off Labels adds a line-and-circle cue in addition to color. Look under Settings > Accessibility > Display & Text Size; if the labels differ, search Settings for the feature name. Apple lists these options in its display color guide and display preferences overview.
What if the screen feels too bright?
Reduce White Point tones down bright colors; it does not enlarge text or interface elements. Find it in the display and text accessibility settings, or search Settings for “Reduce White Point.” Adjust it only if the intensity of bright colors is the issue. Apple includes it among the display accommodations in its display and text size preferences overview.

Which setting should I try first?
| What is hard to see | Try first | What it changes |
|---|---|---|
| Small or thin text | Larger Text; then Bold Text | Text size or weight |
| Icons and buttons seem too small | Display Zoom | Overall interface scale, including icons and controls |
| Buttons blend into content | Show Borders; consider Button Shapes | Visible control boundaries or button cues |
| Content blends into transparent backgrounds | Increase Contrast or Reduce Transparency | Separation between foreground and background |
| Meaning depends on color | Differentiate Without Color; On/Off Labels for switches | Non-color cues |
| Bright colors feel uncomfortable | Reduce White Point | Intensity of bright colors, not size |
There is no single best combination for everyone: the useful adjustment depends on what is difficult to see, and app support can vary. Make one change, check the result in the places you use your iPhone, and return to that setting to turn it off or move its slider back if it does not help.
