Your resized image will appear here Upload an image and choose an Instagram size preset to get started. ## Instagram Image Size Guide (2026) Instagram supports several aspect ratios, each optimized for a different content format. Using the correct dimensions prevents unwanted cropping and ensures your content looks professional in the feed. - **Feed Post (Portrait 4:5):** 1080 x 1350px. Takes up the most screen real estate in the feed. Best for engagement. - **Feed Post (Square 1:1):** 1080 x 1080px, the classic Instagram format, ideal for product photos and graphics. - **Feed Post (Landscape 1.91:1):** 1080 x 566px, best for wide scenes, but takes up less feed space. - **Stories & Reels (9:16):** 1080 x 1920px, full-screen vertical format for immersive content. - **Carousel (1:1):** 1080 x 1080px, multi-image swipeable posts. All slides share the same aspect ratio. - **Profile Picture:** 320 x 320px minimum. Displays as a circle at 110px on mobile. - **IGTV Cover (1:1.55):** 420 x 654px, the thumbnail shown on your IGTV channel grid. ## Tips for Instagram Image Optimization - **Use sRGB color space:** Instagram converts all images to sRGB. Uploading in a different color space can cause color shifts. - **Upload at max resolution:** Instagram compresses your image regardless, so start with the highest quality to minimize artifacts. - **Keep text in safe zones:** For Stories and Reels, keep important text at least 250px from the top and bottom edges to avoid UI overlaps. - **JPG for photos, PNG for graphics:** Use JPG for photographs (smaller file size) and PNG for images with text or transparency. - **Avoid over-filtering:** Instagram's algorithm can detect heavily filtered images. Natural-looking photos tend to get higher reach. - **Test with dark mode:** Many users browse in dark mode. Check that your images look good against both light and dark backgrounds. - **Carousel consistency:** Use the same dimensions for every slide in a carousel. Mixing ratios causes awkward cropping. ### Instagram Image Dimensions Quick Reference (2026) FormatDimensionsRatioBest ForPortrait Post1080 x 13504:5Maximum feed visibilitySquare Post1080 x 10801:1Products, flat laysLandscape Post1080 x 5661.91:1Panoramas, wide shotsStory / Reel1080 x 19209:16Full-screen verticalProfile Picture320 x 3201:1Account avatarIGTV Cover420 x 6541:1.55Video thumbnail ### Automate your Instagram workflow Resize your images here, then schedule them with [PostEverywhere's Instagram scheduler](https://posteverywhere.ai/instagram-scheduler).
