Frequently Asked Questions
Can you bold text on Twitter/X?
Twitter/X does not support native bold text. However, you can use Unicode bold characters that look like bold text and are preserved in tweets. Use this free Twitter text formatter to convert your text to Unicode bold, then copy and paste into X.
Does formatted text count toward the Twitter character limit?
Yes. Unicode bold and italic characters each count as 1-2 characters toward the Twitter 280 character limit. Some characters outside the Basic Multilingual Plane (like some emoji and Unicode mathematical symbols) count as 2 characters in Twitter's character counter.
Does bold text work on X (formerly Twitter)?
Yes. After the rebrand from Twitter to X, Unicode bold and styled characters continue to work in posts. The formatting method is unchanged: Unicode characters are stored as plain text and render as bold/italic on all platforms.
