Frequently Asked Questions
What size should an Instagram post be?
Square posts are 1080x1080px. Portrait posts (4:5) at 1080x1350px get more screen real estate and often higher engagement. Landscape posts are 1080x566px.
What about Instagram Stories and Reels?
Stories and Reels use 1080x1920px (9:16 aspect ratio). This fills the entire screen on most phones.
Will my image be cropped?
Yes — the tool uses a cover-fill approach: it scales your image to fill the target size and center-crops any overflow, so there are no black bars.
