iPhone Wallpaper Sizes: Pixel Dimensions for iPhone 12–18 Pro & Duo (2026)

If you want a wallpaper file that starts at your iPhone's display resolution, use the pixel dimensions below. ShowPro's [iPhone Wallpaper Resizer](https://showprosoftware.com/tools/iphone-wallpaper-resizer) uses these sizes as output targets and center-crops the selected image to fill the screen ratio.

Important: iOS can still crop, zoom or reposition a wallpaper when you apply it, especially around the Lock Screen clock, widgets and rounded display corners. Treat the dimensions below as a practical full-resolution starting point, not a guarantee that every edge of an image will remain visible.

How to resize an image for your iPhone

The resizer uses your selected model's target pixel dimensions and a cover-style center crop. That means it fills the entire output without stretching the image.

What center-crop means

Suppose your source photo is much wider than your iPhone screen. The resizer scales the photo until the target is completely covered, then crops equal amounts from the left and right.

If the source image is much taller, it scales to the target width and crops from the top and bottom.

This is different from stretching. The original aspect ratio is preserved.

Keep important subjects away from the edges

For Lock Screen wallpapers, leave breathing room around:

iOS can reposition the image and overlay the clock, widgets and controls. A wallpaper can have the correct pixel dimensions and still need visual adjustment when you apply it.

Use a sufficiently large source image

If your original image is smaller than the target size, the browser has to scale it up. That can make the result softer.

For the sharpest output, start with an image whose dimensions are at least as large as the target wallpaper resolution.

iPhone Duo needs two different targets

The iPhone Duo has an outer display and a larger folding inner display. Those are different aspect ratios and resolutions, so ShowPro exposes them as two separate choices.

Choose:

Does an iPhone wallpaper have to match the screen resolution exactly?

No. iOS can scale larger images. Matching the display resolution simply gives you a predictable, device-specific output and avoids unnecessary guesswork.

The composition of the image matters as much as the raw pixel count.

Privacy: where does the image processing happen?

The iPhone Wallpaper Resizer performs its image resizing with browser canvas operations. The selected image is processed in your browser rather than uploaded to a ShowPro image-processing endpoint.

ShowPro still uses normal website analytics, so “browser-local file processing” should not be confused with “the website collects no analytics at all.”

FAQ

What size is an iPhone 18 Pro wallpaper?

1206 × 2622 pixels is the display-resolution target used by ShowPro.

What size is an iPhone 18 Pro Max wallpaper?

1320 × 2868 pixels.

What size is an iPhone Duo wallpaper?

The Duo has two displays: 1398 × 2034 for the outer display and 1878 × 2670 for the inner display.

What size is an iPhone Air wallpaper?

1260 × 2736 pixels.

Why does iOS still crop my correctly sized wallpaper?

Wallpaper placement is affected by the image composition, Lock Screen layout and iOS positioning. Exact screen dimensions do not guarantee that every edge remains visible.

Does ShowPro stretch my photo?

No. The current resizer uses a cover-style center crop so the source aspect ratio is preserved while the target canvas is filled.

Are wallpaper images uploaded to ShowPro?

The resizing operation runs in your browser rather than through a ShowPro image-processing server.
