How to convert an image to Instagram post size
Instagram feed posts look sharpest when they match the right dimensions. Convert your image first so the post opens cleanly on mobile without unexpected cuts.
Square posts: 1080 by 1080
The classic Instagram post size is 1:1 at 1080 by 1080 pixels. Use this when you want a balanced feed tile.
Portrait posts: 1080 by 1350
Portrait (4:5) takes more vertical space in the feed. Convert to 1080 by 1350 when you want a taller post.
Landscape posts: about 1080 by 566
Landscape feed posts use roughly a 1.91:1 ratio. Convert to about 1080 by 566 when your photo is wide.
