How to italicize on Twitter (X), step by step
- Write the post in the formatter Open the free X text formatter in your browser, on a phone or a computer, and type or paste your post. No account needed.
- Select the words and press I Select only the words to slant and press I. On a computer, Ctrl/⌘+I works too. Add B for 𝙗𝙤𝙡𝙙 𝙞𝙩𝙖𝙡𝙞𝙘.
- Check the count The formatter counts characters the way X does, with styled letters as 2, and warns you before you go over 280.
- Copy and paste it into X Press Copy text, open X and paste it into a new post, a reply or a quote. It stays italic in the app and on x.com.
Italics with X Premium and in Articles
X does have real formatting, for subscribers. According to X’s help page on Premium, Premium lets you write longer posts of up to 25,000 characters and add rich text, bold and italics, to them, in a post, a quote or a reply. The page doesn’t name the button, and it can move between app versions, so look for the formatting option in your post composer.
Articles go further. They’re for Premium and Premium+ subscribers and some business plans, and their editor has headings, subheadings, bold, italics, strikethrough, indentation and lists. On x.com you open the Articles tab in the side menu, click Write, and Publish when you’re done.
Real italics have one advantage over the pasted kind: they’re normal letters, so search and screen readers read them. If you have Premium, use them in your own posts. If you don’t, or you’re writing your bio, a DM or a reply somewhere else, paste.
Italics on X, place by place
| Place | Italics? | How |
|---|---|---|
| Posts, replies and quotes | Paste it in | Format, copy, paste. Each italic letter counts as 2 |
| Longer posts (Premium) | Built in | Bold and italics in the composer, up to 25,000 characters |
| Articles (Premium) | Built in | Headings, bold, italics, strikethrough and lists |
| Bio | Paste it in | A short italic line reads well; keep the words people search for plain |
| Display name | Possible | Styled letters make you harder to find. Keep your name plain |
| DMs | Paste it in | Fine for a title or a quote |
| Hashtags | No | An italic hashtag is different characters, so it won’t work as a hashtag |
Premium and Articles from X’s help (help.x.com); counting from X’s developer docs.
Why italics eat your 280 characters
X doesn’t count every character the same. Its developer docs on counting characters give Latin letters, punctuation and common symbols a weight of 1, and other Unicode characters a weight of 2. Italic letters come from a separate Unicode block, so each one counts as 2.
How X counts what you type
| You type | Counts as | Example |
|---|---|---|
| Plain letters and punctuation | 1 each | “hello” = 5 |
| Italic or bold letters | 2 each | “𝘩𝘦𝘭𝘭𝘰” = 10 |
| Any emoji | 2 | Even a combined emoji |
| Any link | 23 | X shortens every link with t.co |
| A post (without Premium) | 280 in total | A fully italic post fits about half the words |
How italic text works on X
The post box takes plain text, so the italics you see from people without Premium are characters. Unicode, the standard behind all text on phones and computers, has a block of Mathematical Alphanumeric Symbols: whole alphabets in italic, bold and other styles, made for maths. A formatter swaps your letters for those, and because they’re characters, they survive copy and paste.
- Search can’t find them. An italic word is spelled with different characters, so it won’t match a search for the plain word.
- Screen readers may stumble. Some skip the letters, some read them one by one. Scope recommends plain text for anything everyone must understand.
- Old devices may show boxes. A device without a font for these characters shows small squares. Current phones and browsers show them.
When italics work on X
- Titles. A book, a film, a show or a paper: “Just finished 𝘋𝘶𝘯𝘦” reads cleaner than quote marks.
- The stressed word. “I 𝘯𝘦𝘷𝘦𝘳 said that” and “I never said 𝘵𝘩𝘢𝘵” are different posts. Italics show the reader where your voice goes.
- The aside. A quieter second line under the main one, like a thought you add after a beat.
- Not the whole post. A full post in italics is harder to read, costs twice the characters and loses search.
Bold does the opposite job: it says “this is the point”. Use it for the number or the result, with the X text formatter’s B button.
Italics not showing on X? Quick fixes
- It pasted as normal text. You copied before formatting, or copied from the wrong box. Press Copy text in the formatter and paste again.
- X says the post is too long. The italic letters count double. Slant fewer words, or cut a sentence.
- Some letters show as boxes. The device reading it has no font for them. There’s nothing to fix on your side.
- The numbers stayed upright. Expected: there are no italic digits. Use bold for numbers.
Italics in a real X post
One italic word in the post, and four pictures that make the same point. X shows up to four images per post, so a carousel for X is four slides at most. Pick X in aiCarousels and it makes up to four slides, sized for X. In the post text it writes with them, select a word and press Italic: like the formatter, it uses special characters that X shows as italics.
Other styles and other apps
The X text formatter also does bold, underline and strikethrough, and the X post preview shows where “Show more” cuts your text and how your pictures are cropped. Writing elsewhere? See how to italicize on Instagram and how to bold text in a LinkedIn post.
