Open toolWhy length matters on social media
Each platform caps captions, bios and titles, and feeds cut long text short on small screens. Knowing exactly how many characters you have left helps you put the key message where people will see it.
Each platform counts differently, so there is a dedicated counter for each: the X character counter weighs links and emoji the way X does, the Instagram caption counter tracks hashtags, the TikTok caption counter checks captions and bios, and the YouTube title and tag counter counts tags like YouTube Studio.
