Resize Images for Phone Wallpapers
Each phone model has different screen resolutions. ImageGates resizes your favorite photos to your exact phone screen dimensions — no awkward cropping or stretching. Works for iPhone, Samsung Galaxy, Google Pixel, and all other smartphones.
Phone wallpaper resolutions by device
A wallpaper must match the device's native resolution or the system scales it, and the lock screen clock, widgets and home-screen icons cover predictable regions. Modern phones also apply a parallax zoom that crops a few percent from every edge.
Exact specifications:
- iPhone 15/16 Pro: 1179×2556 px
- iPhone Pro Max: 1290×2796 px
- Samsung Galaxy S series: 1440×3088 px
- Safe universal size: 1440×3200 px (9:20)
- Parallax margin: keep the subject inside the central 90%
What causes a rejected or degraded result:
- Using a 16:9 desktop wallpaper on a 20:9 phone, which is cropped heavily on the sides.
- Placing the subject in the upper third, behind the lock-screen clock.
- Upscaling a small image, which shows banding across large gradient areas.
Preparation order that avoids rework:
- Check the phone's exact screen resolution in settings.
- Crop to that aspect ratio, then resize to the native pixel size.
- Leave the top quarter and bottom icon row visually quiet.
