Why Social Platforms Crop and Blur Uploads

Social networks process millions of media uploads each hour. When you upload a picture that deviates from their recommended dimensions or exceeds file weight limits, their servers execute automatic cropping algorithms and aggressive re-compression. Sizing your graphics correctly prior to upload prevents this penalty.

Instagram Recommended Dimensions

• Square Post: 1080 x 1080 px (1:1 aspect ratio) • Portrait Post: 1080 x 1350 px (4:5 aspect ratio - occupies the most mobile feed screen space!) • Landscape Post: 1080 x 566 px (1.91:1 aspect ratio) • Stories & Reels: 1080 x 1920 px (9:16 vertical full screen) • Profile Picture: 320 x 320 px

Which Instagram post size gets the most engagement?
