The iPhone 17 Pro Max screen size is 6.9″ measured on the diagonal, with a portrait resolution of 1,320 × 2,868 px. That works out to an aspect ratio of 1:2.17 and a pixel density of 460 ppi. The table above has everything in one view.
If you searched for the screen size of iPhone 17 Pro Max, what size screen the iPhone 17 Pro Max has, or what screen size the iPhone 17 Pro Max is, those are the numbers you need. The sections below explain how to use them.
Resolution vs points: what @3x means
There are two ways to describe this screen, and they are not the same thing.
- Pixels: the physical dots on the display, 1,320 × 2,868 px.
- Points: the logical units used in design and code, 440 × 956 pt.
The jump from points to pixels is the scale factor. This phone is @3x, so every point is drawn with three pixels in each direction. A button that is one point wide in your layout is rendered across three physical pixels.
For designers
Design your frames in points, then export assets at 1x, 2x and 3x as needed. If you design directly in pixels, keep in mind that your layout will look three times larger than it really is on the device.
For developers
Layout code in SwiftUI or UIKit uses points. You rarely need to think about raw pixels unless you are working with images, canvases or screenshots. Supply artwork at @3x so it stays sharp on this display.
What the numbers mean for wallpapers, screenshots and app design
The ratio of 1:2.17 is tall and narrow. That matters whenever you place an image on the screen.
Wallpapers
For a wallpaper that fills the screen with no scaling, create the image at 1,320 × 2,868 px. A wider source image will be cropped, so keep important subjects away from the edges. The lock screen also puts a clock and widgets over the image, so leave breathing room near the top.
Screenshots
A native screenshot from this phone matches the full pixel resolution. If you crop or edit it, keep the aspect ratio unchanged to avoid stretching. For social posts, you may need to resize or pad it. The Social Media Image Resizer can help with that.
App design
Design for 440 × 956 pt as your large-phone canvas. Respect safe areas around the Dynamic Island and the home indicator, and test how your layout behaves on smaller phones too. Pixel density of 460 ppi means thin lines and small text render crisply, but touch targets still need to be comfortable for fingers.
App Store screenshot size for iPhone 17 Pro Max
For this device class (iPhone with Dynamic Island, large display), the accepted App Store screenshot sizes are 1,260 × 2,736 px or 1,290 × 2,796 px or 1,320 × 2,868 px.
The last option matches the native screen resolution, so it is the simplest choice if you capture straight from the device or simulator. Pick one size and keep your whole set consistent. Check App Store Connect for the current rules on file format and the number of screenshots, since requirements can change.
Comparison with neighboring models
If you design for more than one phone, it helps to compare sizes side by side. These pages list the exact figures for each model:
- iPhone 17 Pro screen size
- iPhone 17 screen size
- iPhone Air screen size
- iPhone 16 Pro screen size
- iPhone 18 Pro Max screen size
For this model, the reference values are 6.9″, 440 × 956 pt and 1,320 × 2,868 px. Open a neighboring page and compare the points first, since that tells you how much layout space you gain or lose.
How to make a mockup with the tool on this page
You can place a screenshot inside an iPhone frame without installing anything. The steps below are general, and menus can differ by version of the tool.
- Capture or export your screen at 1,320 × 2,868 px so it fits the display without stretching.
- Open the mockup tool on this page and choose the iPhone 17 Pro Max frame.
- Upload your screenshot and check that it fills the screen area.
- Adjust the background, position or angle if the tool offers those options.
- Download the result and use it on your site, store page or social posts.
