X (Twitter) bold text generator
Bold, italic, and 13 more styles for X posts, bios, and display names, with the character-count catch stated plainly.
Works in: Posts ยท Display name ยท Bio ยท Pinned post
X has no bold or italic for regular accounts (Premium's formatting applies only to long-form articles), so styled posts use Unicode's separate bold and italic alphabets. The catch nobody mentions: X counts most styled characters as 2 toward the 280 limit, so a fully bolded post fits half as much text.
What to know before styling X text
- Works in posts, your bio, and your display name; the display name is where a styled word is most common.
- The count cost is real: styled characters live outside X's 1-character ranges, so each counts as 2. Bold one phrase and your budget barely notices; bold the whole post and 280 becomes roughly 140.
- Styled words are not searchable and do not match as hashtags or cashtags, so keep anything discoverable plain.
- Screen readers spell styled text out character by character, which for a long bolded sentence is genuinely unusable. Accent, not body text.
Frequently asked questions
How do I post bold text on X?
Type the text here, copy the bold version, and paste it into the composer. X treats the styled characters as ordinary text; no Premium subscription is involved.
Does bold text count differently toward X's 280 characters?
Yes. X's counter weights most characters outside its basic ranges as 2, and the Unicode styled alphabets fall in that territory. Expect a styled character to cost double, which this page's counter reflects when you paste back into X.
Can I use bold text in my X display name?
Yes, display names accept Unicode freely and it is the most common place to see it. The 50-character name limit applies to what X counts, so a heavily styled name fits fewer letters.
The styling is the garnish. Posting consistently is the meal.
