1:1 Aspect Ratio — Exact Pixel Sizes

What 1:1 means

1:1 is the square ratio — equal width and height. The standard feed-post upload is 1080×1080 px; profile pictures are also 1:1. An aspect ratio is width:height — 1:1 tells you the shape, and the pixel size tells you the resolution to export at. For sharp results, always export at the standard upload size (1080×1080) or larger at the same ratio; never upscale a smaller image.

Every placement that uses 1:1

Across the major networks, 37 placements share the 1:1 ratio. That means one correctly-sized 1080×1080 asset can be reused across many of them — Square feed posts, profile pictures and avatars. The table above lists each with its exact pixels; some platforms accept a higher-resolution version of the same shape (e.g. 1920×1080 instead of 1280×720), which is always safe to use.

Exporting at 1:1 without quality loss

Design on a canvas set to exactly 1:1. Export as PNG for graphics/text or high-quality JPG for photos. Platforms re-compress on upload, so start at the largest 1:1 size listed rather than the smallest — downscaling stays crisp, upscaling does not.
