The fastest way to change your clock display

You can change the clock face on your iPhone's lock screen and home screen by opening Settings, tapping Display & Brightness, then selecting a new clock style. The process takes about 30 seconds. If you're using iOS 16 or later, you also have the option to customize the lock screen directly by long-pressing it and tapping "Customize"—this gives you more control over the clock's size, color, and position.

The clock itself doesn't change—it still shows the correct time. What changes is how that time looks visually: the font, size, color, and sometimes the background behind it. Different clock styles suit different lock screen designs, so you might want to match your clock to a wallpaper or theme you like.

Key Takeaways

  • Open Settings, go to Display & Brightness, and choose a clock style to change how the time appears on your lock screen.
  • On iOS 16 and later, you can long-press your lock screen and tap "Customize" to adjust the clock's color, size, and position directly.
  • The clock style you choose affects only the visual appearance—the actual time and time zone remain unchanged.
  • Some clock styles are tied to specific lock screen themes, so switching themes may change your clock appearance automatically.

Changing the clock through Settings

Go to Settings on your home screen and scroll down to find Display & Brightness. Tap it, then look for the "Lock Screen" option (this appears on iOS 16 and later). Tap Lock Screen, and you'll see a preview of your current lock screen at the top of the screen. Below that, you'll see different clock style options—usually labeled with names like "Mono," "Color," "Gradient," or "Large."

Tap the clock style you want to use. The preview at the top updates when ready so you can see how it looks. Once you've chosen, the change takes effect right away on your lock screen. You don't need to confirm or save anything—just backing out of Settings locks in your choice.

Customizing the clock directly on your lock screen (iOS 16 and later)

If you're running iOS 16 or newer, you can edit your lock screen without going into Settings. Long-press anywhere on your lock screen until a menu appears at the bottom. Tap "Customize." You'll see your lock screen in edit mode with small icons around the clock.

Tap the clock itself to open clock customization options. From here you can change the clock's color, size, and sometimes its position on the screen. The available options depend on which clock style you've selected—some styles offer more customization than others. Tap outside the clock or swipe down to save your changes.

Understanding clock styles and what they look like

iPhone offers several built-in clock styles, though the exact names and number vary by iOS version. "Mono" is a straightforward, single-color clock in a clean font. "Color" displays the time in a colored font that matches your wallpaper or theme. "Gradient" shows the time with a color blend effect. "Large" makes the time take up more of the lock screen, which is useful if you want the clock to be the main focus.

Some clock styles are only available with certain lock screen themes or wallpapers. If you change your wallpaper, the clock style may change automatically to match the new theme. You can always switch back to a different style by returning to Display & Brightness or by long-pressing your lock screen again.

Changing the clock color and appearance

The color of your clock depends on which style you've chosen and which lock screen theme you're using. If you want to change the clock's color, the easiest way is to switch to a different lock screen theme or wallpaper—many themes come with their own clock color built in. Alternatively, long-press your lock screen, tap "Customize," then tap the clock to see if color options are available for your current style.

Not all clock styles allow color changes. If you're using a style that doesn't offer color customization, you'll need to switch to a different clock style to change the color. The "Color" and "Gradient" styles typically offer the most flexibility for adjusting how the clock looks.

What to do if the clock won't change

If you've made a change in Settings but the clock on your lock screen hasn't updated, try restarting your iPhone. Press and hold the power button and volume button together, then slide to power off. Wait a few seconds, then press and hold the power button again until you see the Apple logo.

If you're trying to customize the clock by long-pressing your lock screen and the "Customize" option doesn't appear, make sure you're running iOS 16 or later. You can check your iOS version in Settings under General, then About. If you're on an older version, you can only change the clock style through Display & Brightness in Settings.

Frequently Asked Questions

Can I use a custom clock face from the App Store?

No. iPhone doesn't allow third-party apps to replace the lock screen clock. You're limited to the clock styles that come built into iOS. Some apps can display a clock on your home screen or in widgets, but they can't change the lock screen clock itself.

Will changing the clock style affect my time zone or alarm settings?

No. Changing how the clock looks has no effect on the actual time, your time zone, or any alarms you've set. The time displayed is always correct for your location, regardless of which clock style you choose.

Why did my clock style change when I updated iOS?

Major iOS updates sometimes reset lock screen settings or introduce new clock styles. Your old style may no longer be available, so iOS automatically switches you to a similar one. You can always choose a different style from Display & Brightness or by customizing your lock screen directly.

Can I have different clock styles on different lock screens?

Yes, if you've created multiple lock screens (iOS 16 and later). Each lock screen can have its own clock style, wallpaper, and widgets. Long-press your lock screen, tap "Customize," and adjust the clock for that specific screen. Your other lock screens keep their own settings.
