How URLs and Mentions Count
X automatically shortens any URL to a 23-character t.co link. So a 200-character URL still only counts as 23 in your post. The displayed URL on the post can be longer; the underlying t.co redirect saves space.
Mentions (@username) and hashtags (#tag) count their full character length.
Posts Over 280 Characters — Should You?
Even with X Premium's 4,000-character limit, longer is not always better. Engagement metrics consistently show:
- Posts under 100 characters get 2-3x more engagement than 280-character posts.
- Posts over 280 characters require viewers to click "Show More" — kills CTR.
- The X feed compresses long posts visually, hiding most of the text.
Long-form on X works for thread-style storytelling or essays where you want to keep readers in-feed. For most other use cases, multiple 280-character posts as a thread outperform one long post.
