Available on Premium, Business, Enterprise plans.
Calculate the weighted length, or character count, of a post string for Bluesky, Facebook, Google Business Profile, Instagram, LinkedIn, Pinterest, Reddit, Threads, TikTok, X/Twitter, and YouTube. Checks if the post length is valid and returns the maximum length allowed for each social network. Special characters, such as ü, ø, or 😊, have a higher character count value (unicode). This check is automatically done with the /post endpoint.
The weighted length is an estimate calculated by Ayrshare. Social networks may have slightly different character counts based on their own calculation methods.
