The best iphone wallpaper dimensions would be based on the model of the iphone since not all iphones have the same screen size. As an illustration, the more recent models of iPhones such as the Pro models have higher pixel density and greater aspect ratios. The precision of the dimensions used will make your wallpaper sharp without the need to crop or stretch it. The best thing to do is to ensure that the image resolution perfectly matches the native display resolution of your device so that it fits perfectly on both the lock screen and home screen.
