Social media character counter
Write your post once and check in real time whether it fits the limits for X/Twitter, Instagram, TikTok, YouTube, Google and SMS: each bar turns red the moment you go over.
Platform character limits at a glance
A post on X/Twitter tops out at 280 characters (Premium accounts can go longer, but the preview still gets truncated). Instagram and TikTok captions allow up to 2,200 characters, yet in the Instagram feed only the first few lines show before the "… more" cut-off — the first 125 characters are the ones that really count. A YouTube video title is capped at 100 characters, but search results display only about 70 of them. Google's meta description has no hard limit; around 160 characters it simply gets clipped with an ellipsis, so it pays to stay under that mark.
Watch out for emoji, links and SMS encoding
Not every character weighs the same. On X, every link counts as a flat 23 characters no matter how long it actually is, and many emoji count as 2. For SMS, the 160-character limit only applies to the standard GSM alphabet: a single emoji or special symbol switches the message to Unicode encoding, where the cap drops to 70 characters and the text gets split into multiple concatenated messages. If your message has to fit in a single SMS, skip the emoji and fancy symbols.
