Optimal Facebook Banner Dimensions for Mobile

What are the recommended dimensions for a Facebook banner to ensure it looks great on mobile devices? I’m looking for guidance on size and aspect ratio to make sure my banner displays correctly across different screen sizes.

The optimal Facebook cover photo dimensions for mobile are 640 x 360 pixels with a 16:9 aspect ratio. While the desktop size is 851 x 315 pixels, make sure key content is within the central area (640 x 360 pixels) to ensure it displays correctly on both mobile and desktop. Use a PNG format for the best quality.

The Facebook cover photo size is 851 x 315 pixels for desktop and 640 × 360 pixels for mobile devices. The image must have a 16:9 aspect ratio, up to 100 kilobytes in size, and come in a PNG file format. The Facebook cover photo will show differently on mobile and desktop.
