The classic Instagram square post is 1080x1080 pixels (1:1). It is the safest format if you care about how the post appears across the feed, the profile grid, and embeds. Square posts upload without any cropping and maintain crisp text rendering when exported in PNG.
Tips
- 1Use 1080x1080 minimum — larger square sources (e.g. 2160x2160) get downscaled cleanly.
- 2For carousel posts, every slide must share the same aspect ratio to avoid auto-cropping.
- 3Keep margins of at least 50 px so the subject is not flush with the edge of the frame.
- 4Export with sRGB and JPEG quality 85+ to balance file size and clarity.
Frequently Asked Questions
Are Instagram square posts still recommended in 2026?
Yes. Even after Instagram switched the grid preview to 4:5 in early 2025, 1:1 square posts remain widely used and display perfectly in feeds and embeds.
What is the maximum size for a square Instagram post?
Instagram supports up to 1440x1440 internally, but 1080x1080 is the official recommended size and produces the best balance of clarity and file size.
Will square posts get cropped on the profile grid?
Square posts can appear with a different crop in profile-grid previews. The full square remains visible in the feed and when users open the post.
