How to use it
1Type the word or phrase you want to stand out.
2Choose serif bold, sans bold or one of the bold italic styles.
3Tap or click the style to copy it.
4Paste it into your post, bio or comment, and check how it looks before you publish.
Each letter is a separate Unicode character, so the bold look survives copy and paste. Serif and sans bold come with bold numbers as well, which makes them handy for headings, numbered lists and short labels.
Frequently asked questions
Sans bold (𝗕𝗼𝗹𝗱) looks modern and sits comfortably next to most app fonts, so it works well for headings and list items. Serif bold (𝐁𝐨𝐥𝐝) feels more classic and stands out more from the surrounding text. Both have matching bold numbers.
Yes. Type only that word, copy the bold version and paste it into your text. Bolding one or two key words reads much better than a whole bold paragraph.
Bold Unicode letters are different characters from normal ones, so in-app search and search engines usually won't match a bold word to the same word in plain letters. Keep names, hashtags and keywords you want people to find in plain text.
Serif bold, sans bold and the double-struck (outline) style have their own numbers. Punctuation such as ! and ? and emoji stay as they are, because Unicode has no bold versions of them.
They can. Styled letters sit outside the basic character range, and some apps count each one as two characters, so a long bold bio or post may hit the limit sooner than you expect.
Use it sparingly. Some screen readers read each letter as “mathematical bold” or skip it entirely. Emphasize a heading or a word or two, and keep essential details such as links, phone numbers or codes in plain text.
