Every social platform has different recommended image dimensions. Uploading the wrong size can result in automatic cropping or quality loss. Select a platform preset and your image is instantly resized to the optimal dimensions.
Use 1080×1080 for square posts, 1080×1350 for portrait (4:5 ratio gets more feed real estate), and 1080×1920 for Stories and Reels. The 4:5 portrait ratio is currently favored by the Instagram algorithm for feed reach.
Upload thumbnails at 1280×720 (16:9). For channel art, use 2560×1440 — different areas are shown on TV, desktop, and mobile. Keep key text and logos within the 1546×423 safe zone in the center.
Timeline images are cropped to a 2:1 ratio. Use 1600×900 and place important content in the center to avoid cropping. When posting 4 images, each is displayed at a different ratio, so check previews carefully.
