Free 4K live wallpapers sized exactly 1260 × 2736 for the iPhone Air (6.5") — no crop, no watermark. Set a moving lock screen in one tap on iOS 26.
A ratio of its own at 1260×2736 — between the 17 and the 17 Pro Max, so neither of their exports fits it edge to edge.
Save the wallpaper to your iPhone Air
Open it in 2Live and tap Save. The file arrives at the exact size of your screen, so iOS never re-crops it.
Set it as a Live Photo lock screen
Settings → Wallpaper → Add New Wallpaper → Photos, pick it, then tap the Live Photo icon so it plays on wake. Drag the subject down slightly so the Dynamic Island does not clip it.
1260 × 2736 pixels on a 6.5" display — an aspect ratio of about ≈19.5:9. Anything smaller is upscaled by the OS and looks soft; anything a different shape gets cropped.
Yes. iOS 26 sets a Live Photo as the lock screen, and it plays whenever the screen wakes. That is what 2Live makes — the wallpaper actually moves, which is the one thing saving a picture from a web page cannot give you.
On an OLED panel a true-black pixel is a pixel that is switched off, so a genuinely black wallpaper draws less power — which matters most on a device that keeps the display on. That is why the AMOLED collection leads this page.
