The success of a paid campaign on Facebook and Instagram depends not just on content and targeting, but also on the technical specs of the creative. A wrongly-sized image will be cropped, look blurry, or simply not work. This guide consolidates all the up-to-date sizes for 2025 so you can create perfect ads in every format.
For feed posts: images at 1080x1080 pixels (square) or 1080x1350 (portrait), in PNG or JPG format, up to 30MB. Video in MP4 or MOV, up to 4GB, with 1080x1080 dimensions for desktop and mobile. Carousels support 2-10 images or videos displayed as a gallery.
For stories and reels: optimal dimensions are 1080x1920 pixels (9:16). Make sure the important content is in the safe zone and not cut off by the interface. Marketplace and Messenger ads have unique dimensions — always check Meta's latest guidelines.
General recommendations: check content quality at all resolutions and on all devices. Always use the recommended dimensions, not the minimums. Keep text on images clear and concise. Follow platform updates because specs change over time.
