Social Media Character Counter
Every social media platform has different character limits — and exceeding them means truncated posts, broken captions, or rejected ads. Our character counter shows your text length in real time against every platform limit. See at a glance whether your tweet, caption, bio, or ad copy fits. Covers X (Twitter), Instagram, TikTok, Facebook, LinkedIn, YouTube, Bluesky, and Pinterest. Bookmark this page and use it every time you write. Free, instant, no sign-up.
