The best Instagram feed image size in 2026 is 1080×1350 pixels (4:5 portrait ratio). It takes up the most vertical space in the feed, giving your post more visibility. Instagram's grid changed to a 3:4 tall format in early 2026, so portrait posts now show better on profiles too.
Instagram Stories and Reels should be 1080×1920 pixels at a 9:16 aspect ratio. Keep important text and elements at least 250 pixels from the top and 340 pixels from the bottom to avoid being covered by the Instagram UI.
Yes. Instagram applies its own compression to all uploaded images. Starting from a correctly sized image at high JPEG quality reduces the amount of compression Instagram needs to apply, which results in a sharper final post.
