The iphone wallpaper size is generally determined by the iPhone model. For instance, newer models such as the iPhone 13 or 14 are typically set at sizes of 1170 × 2532 pixels, while larger phone models are 1284 × 2778 pixels. This ensures the wallpaper does not zoom, blur or get cropped. If you are creating your own background image, it’s always recommended to use the exact resolution of the screen of your device to ensure it looks sharp and fits perfectly.
