About this tool
This page opens the character counter with the Twitter/X limit already selected: type or paste your post and watch the 280-character bar fill, with the remaining count updating on every keystroke.
The standard limit for a post on X is 280 characters. This counter counts Unicode code points, so emoji and non-Latin characters count as one each — note that X itself weighs some characters (like CJK) as two, so texts heavy in those scripts may fit slightly less than the counter suggests. Links are another special case: X shortens every URL to a fixed-length t.co link.
Going over? The bar and the remaining number turn red immediately, so you can trim before posting instead of fighting the compose box. Everything runs locally in your browser — drafts never leave your device.
Example. The word hello counts as 5 characters, leaving 275 of the 280 Twitter/X limit and one GSM-7 SMS segment with 155 characters spare.
Limit. One character outside the GSM-7 alphabet switches the whole message to UCS-2, 70 characters or 67 per split segment, and the Twitter tally does not apply CJK double-weight or t.co link length.
