How to Use the Social Media Image Crop & Ratio Advisor
-
1
Enter custom image pixel dimensions (Width & Height) or upload an image to inspect.
-
2
Review calculated exact Aspect Ratio (e.g. 1:1, 4:5, 16:9, 9:16) and Orientation (Square, Landscape, Portrait).
-
3
Compare against the official platform sizing matrix: Instagram Feed, Reels/Stories, Twitter Header, LinkedIn Banner, YouTube Thumbnail, TikTok.
-
4
See which platforms your image dimensions fit natively without awkward black letterboxing or cropped faces.
-
5
Calculate scaled target dimensions to resize cleanly.
Practical Example & Use Case
Common Real-World Scenario
Checking whether a 1080x1350 pixel graphic matches Instagram's optimal 4:5 vertical feed ratio before scheduling a carousel.
Technical Notes & Limitations
Browser Engine Architecture
Mathematical ratio reduction using greatest common divisor (GCD) algorithms and platform standard specifications.
