X, the app most people still call Twitter, has no bold button for normal posts. These fonts for Twitter give you bold, italic and fancy text for your display name, bio and posts, made from Unicode letters that paste anywhere on X.
There is one thing most pages skip, and it changes how you should use these styles. X counts most styled letters as two characters, so a fully styled post runs out of room much faster than you expect.
How Fonts for Twitter Work
Fonts for Twitter are Unicode characters that look like a different typeface, such as 𝐡𝐞𝐥𝐥𝐨 𝐭𝐡𝐞𝐫𝐞 in bold or 𝒽ℯ𝓁𝓁ℴ 𝓉𝒽ℯ𝓇ℯ in script. X stores them as plain text, and they keep their look in replies and quotes.
You do not need an app or a paid plan for this. You type in the box above, tap Copy on a card, and paste the result wherever X lets you type.
Where Styled Text Works on X
Each part of an X profile has its own rules and limits. Here is what we found when we set up profiles with these styles.
Display Name
Your display name can hold up to 50 characters, and it accepts styled letters and symbol frames. Styled letters can take extra room in that count, which makes short styled names the safest choice.
Bio
The bio gives you 160 characters. We think it works best with one styled phrase, such as your role or a short motto, followed by plain words that people can search for.
Handle
Your handle, the part after the @ sign, is strict. It only takes letters, numbers and underscores, up to 15 characters, and every styled style on this page is refused there.
Posts and Replies
Posts and replies accept styled text with no trouble. Free accounts get 280 characters per post, and longer posts are a paid feature, which makes the double count matter most on standard accounts.
Why Does Styled Text Count Double on X?
X weighs characters when it counts them. Normal letters count as one, while many other characters, including the mathematical letters behind bold, italic and script styles, count as two.
In practice, a post written entirely in bold holds about 140 letters instead of 280. Styling one key word or a short opening line keeps the effect and leaves you plenty of room for the rest.
Combining styles like Strikethrough and Underline have a hidden cost of their own. They add a separate mark after every letter, which can more than double the count of the word you style.
Adding Bold Text to an X Post
Bold is the style people ask about most, and it takes only a few taps:
- Type the Words to Bold: Enter only the words you want to stand out in the Your text box, not the whole post.
- Open Letter Styles: Tap Letter styles to bring bold, italic, bold italic and sans bold to the top of the list.
- Copy the Bold Card: Tap Copy under Bold, or under Sans Bold if you prefer a cleaner look without serifs.
- Write Your Post on X: Paste the bold words where you want them and type the rest of the post normally around them.
- Watch the Counter: Check the circle that fills up as you type, since the styled words use more of it than plain ones.
Are Fancy Fonts Bad for Reach or Accessibility?
Styled text does not lower your reach by itself. But X search matches plain letters, and a post where every word is styled is harder for people to find when they search for that topic.
Accessibility is the bigger concern for us. Some screen readers announce each styled letter with a long technical name, which turns a short post into a long, confusing listen.
That is why we keep the main message plain and use styled text as a small accent. A bold label like 𝐔𝐏𝐃𝐀𝐓𝐄 followed by normal sentences reads well for everyone.
What Works Best on X?
For posts, bold or sans bold on one or two words gives the clearest result. For your display name, a simple frame such as ★hello there★ adds personality without crowding your profile.
