How to Crop a Wallpaper for iPhone

You found a great image, set it as your wallpaper, and iOS zoomed in and chopped off the part you liked. That’s not a bug — it’s iPhone auto-filling the screen with whatever you hand it. The fix is to crop the image to the iPhone’s aspect ratio before you set it, so the phone has nothing to zoom into. Here’s how.

Why iOS zooms your image

iPhone wallpapers must fill a tall, narrow screen. If your photo is wider or squarer than that, iOS enlarges it until it covers every pixel, pushing the edges out of frame. Match the shape first and the auto-zoom disappears.

The target dimensions

Modern iPhones use a screen ratio very close to 9:19.5. For a pixel-perfect fit, crop to:

• 1290 × 2796 — iPhone 15/16/17 Pro Max class
• 1179 × 2556 — iPhone 15/16/17 standard and Pro
• 1170 × 2532 — iPhone 12/13/14

When in doubt, 1290 × 2796 is the safe choice — it’s high enough that iOS scales it down (which stays sharp) rather than up.

Crop inside the Photos app

You don’t need a separate app for a basic crop.

1. Open Photos and tap the image.
2. Tap Edit, then the Crop tool (the overlapping-corners icon at the bottom).
3. Tap the aspect ratio button (top of the screen on most iOS versions).
4. There’s no single “iPhone” preset, so choose a tall portrait ratio. If your version offers a custom or freeform option, drag the corners to a tall rectangle; otherwise pick the tallest portrait preset available.
5. Drag the image within the frame to choose what stays visible.
6. Tap Done.

The catch: the Photos presets are limited and may not hit 9:19.5 exactly. For a precise crop, use an editor that lets you type the ratio.

A precise crop in an editor

In the Wallpaper Hub editor you can set a true iPhone canvas and drag your image inside it, so the export already matches the screen — no guessing with freeform corners. That’s the most reliable way to get an exact fit, especially for images you plan to reuse across devices.

Position the subject for the clock

Cropping isn’t only about the ratio — it’s your chance to place the important part of the image where the clock and widgets won’t cover it.

• Keep faces and focal points in the middle third of the frame.
• Leave the top third relatively open for the clock.
• If you want the subject to overlap the clock, position it just below center so Depth Effect can layer the clock behind it.

There’s more on clock placement in our guide to Lock Screen customization.

Set the cropped image

Once the crop matches the screen:

1. Open Settings > Wallpaper > Add New Wallpaper, or touch and hold the Lock Screen and tap +.
2. Choose Photos and select your cropped image.
3. Because the ratio already fits, you shouldn’t need to zoom — just confirm and tap Add.

If you still see a little extra room, pinch slightly to fine-tune, then set it.

Turn off Perspective Zoom

iPhone has a subtle motion effect that pans the wallpaper as you tilt the phone, which can reveal cropped edges. On a still wallpaper, the parallax is minimal, but if you notice drift, keeping the image at full screen ratio (as above) prevents any empty gaps from showing.

Quick reference

• Crop to 9:19.5, ideally 1290 × 2796.
• Keep the subject out of the top third unless you want Depth Effect.
• Use an editor for an exact ratio; Photos for a quick approximate crop.

FAQ

Why is my wallpaper still blurry after cropping? You probably cropped a low-resolution source. Start from an image at least 1290 pixels wide; enlarging a small photo can’t add detail.

Do I need a different crop for the Home and Lock Screens? No — both screens use the same portrait ratio. One correctly cropped image works for both.
