About the Instagram post (portrait) size
The strongest Instagram post size today is 1080 by 1350 pixels, a 4:5 portrait. Portrait posts take up more vertical space in the feed than the old 1080 by 1080 square, so they earn more attention as people scroll. Instagram still supports the classic square and a 1.91:1 landscape, but if you only make one size, make it 4:5 portrait. Upload at 1080 pixels wide and Instagram keeps the quality; go narrower and it upscales and softens.
Quick tips
- 01Portrait 1080 by 1350 is the default worth designing for; it wins the most feed real estate.
- 02Your profile grid crops every post to a centre square, so keep the subject centred.
- 03Stay under 30 MB and use JPG for photos, PNG for graphics with sharp text.
