Copy a bio or caption in bold, italic, script and other Unicode styles, see it on an Instagram profile, and learn what styled letters break. Free.
By Mellow ยท UpdatedOnly the letters A to Z are styled, and digits in most styles: Italic, Serif italic and Script leave numbers plain. Letters of other alphabets, such as Cyrillic or Greek, stay as they are, and an accented letter is styled under its accent. Underline and strikethrough add a mark to every character instead.

78 of 150 characters as you see them, 130 in UTF-16 units. Instagram allows a bio of up to 150 characters without saying how it counts them, and a styled letter is one character on screen but two in most text boxes, so check a long bio in the app.

Drawn with this deviceโs fonts. The letters look styled wherever the readerโs phone or computer has a font for them, as current systems do.

You canโt pick a font for a bio or a caption: Instagramโs Help Center describes no font or bold setting for either. What sites call Instagram fonts are Unicode characters, the Latin letters drawn bold, italic, script or monospace, which Unicode encodes as mathematical symbols. Type your words above, copy the style you want and paste it into your bio or caption. The letters look styled wherever the readerโs phone or computer has a font for them; keep them to a few words, for the reasons below.

The examples are made by the same code as the generator. Italic, Serif italic and Script have no digits, so numbers stay plain in them. Underline and strikethrough are not styled letters but a mark added after every character, in any alphabet; some fonts draw the line with gaps.
Up to 150 characters, says Instagramโs Help Center, without saying how they are counted. A styled letter is one character on screen but two UTF-16 units, the count most web text boxes use, so a bio written mostly in styled letters can reach a limit sooner than it looks. The bio preview above counts both. Captions can be longer: Mellow Hub accepts an Instagram caption of up to 2,200 characters, counted in UTF-16 units. For hashtags, use the hashtag counter.

Not with a setting: Instagramโs Help Center describes no font or bold option for a bio or a caption. What you can do is paste text written in Unicodeโs styled letters, like the ones this generator makes, which show as bold, italic or script wherever the readerโs device has a font for them.
Yes. They are ordinary Unicode characters, so they paste into a caption or a comment like any other text, with the same costs. Keep hashtags and @mentions in plain letters: a styled hashtag is a different tag, and a styled name is not the account. The generator leaves them plain unless you tell it not to.
It depends on the screen reader and its settings. NVDA, a free screen reader for Windows, has spoken the bold and italic letters used on social media as plain letters by default since version 2025.1, and its makers say such characters can be unknown to a particular speech synthesizer or braille table. A screen reader that doesnโt translate them may spell them out one by one, read their mathematical names or skip them, so keep anything important in plain letters.
The generator styles the Latin letters A to Z and, in most styles, the digits 0 to 9. Cyrillic, Arabic, Chinese and other alphabets are left as they are. An accented letter such as รฉ is styled as its base letter with the accent kept as a separate mark, so it still reads as รฉ.
Instagram hasnโt said that styled letters change how a profile or a post is shown, and we have no data showing that they do. The costs we can state are the ones on this page: some screen readers struggle with them, a search may not match them to plain words, and a styled hashtag is not the plain one.
No. The generator runs in this page. Your text is not sent to Mellow or anyone else, and refreshing the page brings back the example.
Mellow Hub publishes one post to Instagram, TikTok, YouTube, X, LinkedIn, Threads, Bluesky, Pinterest and Facebook, and checks each networkโs rules before anything is sent. It counts an Instagram caption in UTF-16 units, so each styled letter takes two of the 2,200 characters it allows. The hashtag counter checks the captionโs hashtags against each networkโs limit.
