About the Instagram portrait post size
The Instagram portrait size is 1080 by 1350 pixels, a 4:5 ratio. This is the tallest a single feed image can go; anything taller gets cropped to 4:5 on upload. Portrait is the smart default because it occupies more vertical space than a square as people thumb past, without tripping the crop. If your artwork is taller than 4:5, add margins to bring it back to 1080 by 1350 rather than letting Instagram decide where to cut.
Quick tips
- 014:5 (1080 by 1350) is the tallest single image the feed accepts.
- 02Taller source art is cropped to 4:5; pad it yourself to control the crop.
- 03Great for text-heavy graphics because the extra height fits more.
