Bold Text Generator: Bold Sans, Bold Serif and Bold Italic Letters

Facebook posts and comments have no bold button, so type the words above, copy the Bold Sans result and paste it into the post. The letters are Unicode characters that are bold in themselves, and Facebook shows them as typed on every device. Only Facebook Notes and some Page tools have real formatting; for a post, this is the way.

Yes, in posts, comments, the headline and the About section. LinkedIn has no bold control in any of them, which is why a LinkedIn bold text generator is one of the common searches. Keep it to a heading or one key phrase: LinkedIn search does not match bold letters against regular spelling, and long bold passages are hard on screen readers.

Unicode has bold digits (𝟬–𝟵 sans, 𝟎–𝟗 serif) but no bold italic digits, because mathematics never needed slanted numbers. Bold Sans and Bold Serif carry digits in full; Bold Italic Sans and Bold Italic Serif leave 0–9 unchanged, which the glyph maps above show as dashed cells.

No. Ctrl+B is a formatting instruction that stays inside the app that understands it, and is lost the moment the text is pasted somewhere plain. The bold here is baked into the characters themselves, so it survives copy and paste anywhere text is allowed. The trade-off is that the characters are not the letters A–Z, so search, hashtags and spell-check treat them as different words.

Bold Sans matches the interface fonts of Facebook, Instagram, LinkedIn, X and Discord, so it looks like the app itself is bold. Bold Serif looks like a newspaper headline dropped into the post and stands out more, at the cost of looking pasted in. For a bio or a name, sans; for a quote or a title, serif.

Not in the @handle: Instagram, X, TikTok and Discord all restrict handles to ordinary letters, digits, underscores and, on some, periods. The display name next to it accepts bold letters on all four, and so do bios, posts, captions and messages. The compatibility list above states this per field.
