Looking to make your custom designs look like they've been produced in a factory? It's all about the resolution of your Iphone wallpaper to the resolution of your display's hardware. Modern Pro Max models will need more pixels than base models, do not use a "one size fits all" image. When you're looking for graphics, make sure that the iphone wallpaper size is either the same or bigger than your device's native size. This little extra planning makes sure your images aren't just clear, but right at the moment you wake up your phone they're aligned with your widgets and lock screen layout, every time.
