Social media specs

Use this before you write a caption, export an image or video, or schedule a post. Every number here comes from the platform's own documentation; the full dataset with a source link per row, a counting library and a CLI is social-media-specs.

If Node is available, check instead of counting by eye:

npx social-media-specs fit "<caption>"                              # every channel at once
npx social-media-specs media instagram-reel 1080x1920 --video --seconds 40
npx social-media-specs ad meta.primary-text "<ad text>"
