Instagram Ad Specs and Dimensions 2026
Instagram is one of the most visually unforgiving ad platforms out there. A slightly off aspect ratio, an oversized file, or a cropped caption can turn a stunning creative into something that looks amateurish — and kills your results before your audience even reads the copy. With placements spanning Feed, Stories, Reels, Explore, and Shopping, keeping track of every spec is no small task. This cheat sheet brings every Instagram ad dimension, file size, aspect ratio, and text limit together in one clean, scannable reference — so your creative always looks exactly the way it was meant to.
