You can bold, italicise and strikethrough text in YouTube comments using simple symbols. Put asterisks around a word for bold, underscores for italics and hyphens for strikethrough. YouTube officially supports all three on desktop and mobile. This guide shows the exact symbols, where people go wrong, how to add emojis and links, and how to make comments stand out without looking spammy.

The short version: *bold*, _italics_, -strikethrough-. No spaces inside the symbols.
If you’re a creator, the second half of this guide covers the comment tools that matter more for growth: pinning, hearting, replying and keeping your comment section clean.
Why listen to me? I’m Alan Spicer, a YouTube Certified Expert since 2017. I’ve been creating on YouTube since 2012, coached 500+ creators and earned six Silver Play Buttons, and I made a video on this exact trick for my own channel. Small details like comment formatting matter more than people think, because a clear, friendly comment section keeps people talking.

⚡ QUICK ANSWER: How do you bold YouTube comments?
To bold text in a YouTube comment, put an asterisk on each side of the word or phrase, like *bold*. Use underscores for italics (_italics_) and hyphens for strikethrough (-strikethrough-). YouTube officially supports all three on desktop and mobile, and the symbols disappear once you post.
That isn’t a hack. YouTube Help says you can use rich text in comments with common special tags such as *bold text*, _italicised text_ and -strikethrough text- (YouTube Help).
| Effect | What to type | What it looks like |
|---|---|---|
| Bold | *bold* |

| Italics | _italics_ |

How do you bold YouTube comments?
To bold a YouTube comment, put an asterisk directly before and directly after the word or phrase you want to highlight. Once you post the comment, the asterisks disappear and the word shows in bold.
Example:
I loved this *video*!
Best uses for bold comments
- Highlighting one key word
- Making a question easier to spot
- Adding emphasis without writing in capitals
- Making a long reply easier to skim
Best practice: bold one or two key words, not the whole comment. Too much bold looks messy and can feel spammy.
How do you italicise YouTube comments?
To italicise a YouTube comment, place an underscore directly before and directly after the word or phrase. Italics are good for softer emphasis, sarcasm, quoted thoughts or a light nudge on a phrase without the weight of bold.
Example:
This part was _very_ useful.
How do you strikethrough YouTube comments?
To strikethrough a YouTube comment, put a hyphen on each side of the word or phrase. Strikethrough is often used for humour, irony or a playful correction, because readers can still see what you crossed out.
Example:
I was definitely not -crying- laughing at this.
When strikethrough works best
- Jokes and playful edits
- Light sarcasm
- Correcting yourself without deleting the original point
- Making a comment feel more conversational
Can you combine bold, italics and strikethrough?
Yes. You can use bold, italics and strikethrough in the same YouTube comment, as long as each formatted section has its own pair of symbols around it.
Example:
This part was *brilliant*, that section felt _underrated_, and this joke was -totally unnecessary- perfect.
A few small touches look cleaner and more intentional than formatting one big block of text.
Does YouTube comment formatting work on mobile and desktop?
Yes. YouTube comment formatting works the same on desktop and mobile. YouTube’s help pages for both computers and Android list the same rich text tags for bold, italics and strikethrough.
| Platform | Bold | Italics | Strikethrough | Emojis |
|---|---|---|---|---|
| Desktop browser | Yes | Yes | Yes | Yes |
| YouTube app (Android and iPhone) | Yes | Yes | Yes | Yes |
That means the same symbols work whether you comment from a phone, tablet or computer.
How do you add emojis and links to YouTube comments?
You add emojis to YouTube comments with your device’s emoji picker. On a phone it’s built into the keyboard; on a computer you open it with a shortcut.
| Device | How to add emojis |
|---|---|
| Windows | Press Windows key + . (full stop) or Windows key + ; |
| Mac | Press Control + Command + Space |
| Phone or tablet | Use the emoji button on your keyboard |
Links work too. YouTube Help says a URL you add to a comment shows as a hyperlink (YouTube Help). Use them sparingly: link-heavy comments are exactly what spam filters look for, and many creators hold comments with links for review.
Why is YouTube comment formatting not working?
YouTube comment formatting usually fails because of a stray space or a missing symbol. These are the common mistakes and the fixes.
| Mistake | What happens | How to fix it |
|---|---|---|
| Spaces inside the symbols | The text may not format | Keep the symbol tight against the first and last letter |
| Using the wrong symbol | The text stays plain | Use * for bold, _ for italics, - for strikethrough |
| A symbol on one side only | The symbol shows as normal text | Check you have a pair, one before and one after |
| Formatting the whole comment | It looks spammy or messy | Use formatting for emphasis only |
Simple rule: if the word you want to style sits inside the symbols with no stray spaces, it should work.
How do you use formatted comments without looking spammy?
You avoid looking spammy by formatting one useful point, not the whole comment. YouTube removes a huge volume of spam: its Community Guidelines transparency report shows it removed 1,551,576,962 comments between April and June 2026, and 1,310,221,998 of them (84.4%) were for spam, deceptive practices and scams. More than 99.9% were first caught by automated systems, so comments that look like spam can get filtered even when you mean well.

The best formatted comments highlight one useful point, make a question easier to notice, or add a little personality without hurting readability. Overdo it and people stop seeing emphasis and start seeing noise.
| Better use | Worse use |
|---|---|
*What mic are you using?* |
*WHAT MIC ARE YOU USING PLEASE REPLY NOW* |
This part was _really_ useful. |
_This whole paragraph is in italics for no reason at all._ |
I was definitely not -replaying this three times- impressed. |
-Everything- in -this- sentence -looks- strange. |
Which comment tools should creators use?
Pinning, hearting and replying to comments do far more for a creator’s channel than formatting. YouTube Help says you can pin one comment to the top of the comment section once advanced features are turned on, heart viewers’ comments to show appreciation, and on Android reply to comments by voice (YouTube Help).
- Pin a comment with your key link, a question for viewers or a correction. A bolded question in a pinned comment is easy to spot.
- Heart good comments so viewers get a notification and feel seen.
- Reply early in the first hour after upload, when people are still on the page.
- Use comments as research: repeated questions are your next video ideas.

People also ask
Why is my YouTube comment not bold?
Usually there’s a space between the asterisk and the text, or a symbol is missing on one side. Keep the asterisks tight against the first and last letter, like *this*.
Can creators pin or heart a formatted comment?
Yes. Formatting doesn’t change what creators can do with a comment. Pinning needs advanced features turned on, according to YouTube Help.
Does formatting help your comment get noticed?
A little, if you keep it to one or two words. A question in bold is easier to spot; a whole comment in bold looks like spam.
What I would do for better YouTube comments
- Use formatting lightly, not constantly.
- Highlight one word or phrase, not the whole comment.
- Use emojis to support tone, not replace words.
- Make the comment useful, funny or interesting.
- Put readability first and flair second.
Frequently asked questions
How do you bold text in a YouTube comment?
Put an asterisk directly before and after the word or phrase, like *bold*, with no spaces between the asterisks and the text. When you post the comment, the asterisks disappear and the text shows in bold.
How do you italicise text in a YouTube comment?
Put an underscore directly before and after the word or phrase, like _italics_. It works the same way as bold: no spaces inside the underscores, and the underscores vanish once the comment is posted.
How do you strikethrough text in a YouTube comment?
Put a hyphen directly before and after the word or phrase, like -strikethrough-. Strikethrough is handy for jokes and playful corrections, where you want readers to see what you crossed out.
Does YouTube comment formatting still work in 2026?
Yes. YouTube Help still documents rich text in comments using *bold text*, _italicised text_ and -strikethrough text-, on both the desktop and Android versions of its help page, checked in October 2026.
Can you bold YouTube comments on mobile?
Yes. The same symbols work in the YouTube app on Android and iPhone as on a computer. Type the asterisks, underscores or hyphens around your text before you tap send.
Can you add emojis to YouTube comments?
Yes. On a phone, use your keyboard’s emoji button. On Windows, press the Windows key and the full stop. On a Mac, press Control, Command and Space together to open the emoji picker.
Can you add links to YouTube comments?
Yes. YouTube Help says a URL you add to a comment shows as a hyperlink. Use links sparingly, because YouTube’s spam filters watch for link-heavy comments and creators can hold them for review.
Can you combine bold and italics in one YouTube comment?
Yes. You can use bold, italics and strikethrough on different words in the same comment, as long as each formatted section has its own pair of symbols around it.
Final thoughts
To bold text in a YouTube comment, put an asterisk on each side of the word or phrase. Use underscores for italics and hyphens for strikethrough. YouTube officially supports all three, on mobile and desktop.
Used lightly, formatting helps your comments stand out and makes your meaning clearer. For creators, pinning, hearting and replying matter even more.
