Bold text for X, ready to paste.
X has no bold button for normal posts. Type your text, pick a style, and copy it, with the count X will actually use.
The short answer
You can't bold text in a normal X post using a button, so people paste Unicode letters that look bold. Type your text above, then copy the bold version into X. X counts these letters as two characters each, so styled text uses up your 280 faster.
When it helps, and when it doesn't
- Good for one word or a short label in a long post or a thread.
- Bad for whole sentences. It's harder to read, and it uses twice the characters.
- Don't style words you want found. Search may not match these letters, and screen readers can read them badly.
- Never style your handle or a link. They won't work.
Questions
How do you bold text on X (Twitter)?
X has no bold button for normal posts. Type your text above, copy the bold version, and paste it into your post.
Why does bold text use up my characters faster?
These letters come from outside the normal Latin range, and X counts those as two characters each.
Will bold text hurt my reach?
X doesn't publish anything specific about this. The clearer risks are that screen readers struggle with it and search may not find those words.
Does it work in my X bio and display name?
It usually pastes fine in both, but keep the words you want people to search for in normal text.
Keep your LinkedIn and X going without writing every post.
