X Post Checker is designed for the exact search intent behind “x post character counter”. Count X post characters using current standard-post rules while accounting for URL shortening and Premium longer-post differences. Count X post characters using current standard-post rules while accounting for URL shortening and Premium longer-post differences. Standard-post limit X currently documents standard posts up to 280 characters. Longer Premium posts X Premium supports longer posts beyond the standard limit, currently documented up to 25,000 characters on supported surfaces. URLs use t.co length X shortens posted URLs with t.co; X documents that a URL counts as 23 characters in the post counter. Worked example: A standard post with a long URL should count the URL using X's t.co character treatment rather than the visible raw URL length. Common practical uses include Check standard posts; Measure posts containing links; Compare hooks; Avoid standard-post overflows. Important limitations: X limits/features can change. Unicode character weighting can differ from naive string length. Premium post rules are distinct from standard posts. Key questions this page should answer include: What is the standard X post limit? 280 characters. Can Premium users post longer text? Yes; X currently documents longer posts up to 25,000 characters. How many characters does a URL count as? X currently documents URLs as 23 characters after t.co handling. Do photos count toward the text limit? X states photo/GIF attachments do not consume post characters. Can X rules change? Yes. The page should stay focused on this differentiator: Standard-post limit. The tool should appear before the explanatory copy so a visitor can complete the task immediately, then use the supporting content to verify the method and understand the result. The explanation should keep terminology consistent with the calculator or converter interface, because a mismatch between labels in the tool and labels in the content can create confusion and weaken search-intent alignment. Where the calculation or transformation has edge cases, the page should state them directly instead of implying that every input is valid.
