Italic, strikethrough, monospace on LinkedIn — the complete formatting guide.

Bold gets most of the attention, but it is only one part of the LinkedIn formatting toolkit. Unicode gives you italic, bold italic, monospace, underline-like combining marks, strikethrough, double underline, overline, script, sans, and fraktur styles. Some are useful. Some are theatrical. The difference matters.

LinkedIn does not provide native formatting controls for normal posts, so these styles work by replacing or modifying characters. That means they survive copy-paste, but they should be used as writing aids, not decoration. The Crafzo editor makes the styles easy to apply while keeping the post plain enough to read.

Italic on LinkedIn

Italic is best for a softer kind of emphasis. Use it for a phrase that needs a different voice, a quoted thought, or a contrast that should not feel as loud as bold.

Normal: This is the part nobody mentions.
Italic: 𝑇ℎ𝑖𝑠 𝑖𝑠 𝑡ℎ𝑒 𝑝𝑎𝑟𝑡 nobody mentions.

Italic can be harder to read on small screens, especially when the phrase is long. Keep it short. A two-word italic phrase often works better than an italic sentence.

If you are deciding between bold and italic, ask whether the phrase is a signpost or a tone shift. Signposts get bold. Tone shifts get italic.

Strikethrough

Strikethrough is useful when the edit is the point. It can show a changed belief, a rejected assumption, or a joke with restraint.

I thought the problem was h̶i̶r̶i̶n̶g̶ focus.

This works because the crossed-out word is short. Strikethrough on a full sentence is visually messy. It also uses combining characters, which can look slightly different across devices. Preview it before publishing.

Strikethrough is especially good in posts about learning:

Old plan: s̶h̶i̶p̶ ̶m̶o̶r̶e̶ ship smaller.

Use it when the deletion carries meaning. Do not use it just because the toolbar has a button.

Monospace

Monospace is underrated. It works for product names, code-like labels, commands, formulas, metrics, and tiny before-after snippets.

We renamed `activation_rate` to 𝚏𝚒𝚛𝚜𝚝_𝚟𝚊𝚕𝚞𝚎_𝚛𝚊𝚝𝚎.

Monospace tells the reader, "This is a token." It is better than bold when the phrase is technical or literal. If your post includes ChatGPT output with inline code, Crafzo converts the backticked phrase into monospace Unicode during paste. That workflow is covered in Pasting from ChatGPT to LinkedIn.

Underline, double underline, and overline

LinkedIn has no native underline button for posts. Unicode combining marks can simulate underline and overline by adding a mark to each character.

U̲n̲d̲e̲r̲l̲i̲n̲e̲
D̳o̳u̳b̳l̳e̳
O̅v̅e̅r̅l̅i̅n̅e̅

These are more fragile than bold or italic. They can look uneven, and they can make text harder to select. Use them sparingly. Underline can be useful for a single word in a playful post, but it rarely belongs in a serious business update.

Script and fraktur

Script and fraktur alphabets are expressive, but they are rarely the right choice for a LinkedIn post. They reduce readability and can make a professional post feel like a novelty graphic.

There are exceptions. A designer showing typography experiments might use script. A personal milestone post might use a single script word. But if the goal is clarity, skip them.

The strongest formatting style is often the one you do not use.

Formatting and accessibility

Unicode styles are real characters, not semantic formatting. That creates accessibility tradeoffs. Some screen readers may announce styled letters in awkward ways. Some search systems may not match the styled word to the plain word. Some unusual styles may not render on every device.

This does not mean "never use Unicode." It means "use it for emphasis, not for the whole message." Keep names, key terms, and important searchable phrases mostly plain. If your post depends on someone understanding a word, do not hide that word in an exotic alphabet.

For bold specifically, read How to bold text on LinkedIn. The same principle applies: use formatting to help scanning, not to carry the idea.

A simple style hierarchy

Here is a practical hierarchy for LinkedIn formatting:

1. Plain text for the core idea.
2. Bold for section labels and key scan points.
3. Italic for tone shifts or brief emphasis.
4. Monospace for technical tokens.
5. Strikethrough for changed thinking.
6. Underline and decorative fonts only when the style itself adds meaning.

This hierarchy keeps the post readable. It also prevents the common mistake of using every style in one draft.

Preview before you publish

The final check is not aesthetic. It is functional. Does the formatting make the post easier to skim? Does the first 210 characters still carry the hook? Does mobile width make any styled line wrap awkwardly? Do hashtags still look clean?

Crafzo's preview exists because formatting decisions are contextual. A phrase that looks tasteful in the editor can feel too loud in the LinkedIn card. A monospace token can wrap oddly on mobile. A strikethrough joke can become unreadable.

If the format helps the reader continue, keep it. If it makes the reader admire the formatting, remove it. The post is not a poster. It is a piece of thinking trying to survive a crowded feed.
