Why is 1080x1920 the standard size for Stories and Reels?
1080x1920 pixels gives a 9:16 aspect ratio, which fills a phone screen edge to edge with no black bars or cropping. This exact size and ratio is shared across Instagram Stories, Instagram Reels, TikTok, YouTube Shorts, Facebook Stories and Snapchat. Content created once at 1080x1920 can be reused across all of these platforms without resizing again.
