Social Media Character Counter
This free social media character counter measures your caption against every major platform at once — X (Twitter), Facebook, Instagram, LinkedIn, TikTok, YouTube and LINE. Built for social media managers and copywriters who post in Thai and English, it counts Thai characters correctly and applies X’s weighted rules, so links count as 23 and Thai counts as 1. It all runs in your browser.
Your browser does not support precise Thai segmentation — grapheme counts are approximate.
