Using the wrong image dimensions on Instagram can result in cropped visuals, pixelation, and an unprofessional appearance. Here's the definitive size guide for 2025.
Square Post: 1080 x 1080px
The most versatile format. Works everywhere and maintains quality across devices.
Portrait Post: 1080 x 1350px
Takes up more feed space, resulting in higher visibility and engagement.
Stories & Reels: 1080 x 1920px
Full-screen vertical format. Keep important content within the safe zone (250px from top and bottom).
Carousel: 1080 x 1080px or 1080 x 1350px
