How to Bold Text on LinkedIn

The editor at the top of this page is a cut-down version of our LinkedIn post formatter with a single job: making words bold. It works in any modern browser and needs no account.

1. Write or paste your text. Type straight into the editor, or paste a draft you wrote elsewhere. Line breaks and emoji are kept as they are.
2. Select the words to emphasise. Drag across them with the mouse, or hold Shift and use the arrow keys. On a phone, long-press a word and drag the handles.
3. Press Bold or Ctrl+B. On a Mac the shortcut is ⌘B. The selected letters switch to their bold Unicode equivalents and the preview beside the editor updates at once. Press Bold a second time to turn the selection back into plain letters.
4. Copy and paste into LinkedIn. Press Copy, open LinkedIn, click into a new post, comment or profile field and paste. The bold comes across with the text.

If Copy reports a problem, your browser blocked clipboard access. Select the text in the editor and press Ctrl+C (⌘C) instead; the result is identical.

LinkedIn’s post box accepts plain text only. It keeps your words, line breaks and emoji, but it strips the hidden formatting that word processors attach to text. That is why bold copied from Word or Google Docs arrives as ordinary letters.

Unicode, the standard that defines every character your phone can display, includes a block called Mathematical Alphanumeric Symbols. Mathematicians use it so that a bold x and a plain x can mean different things in a formula. The block contains complete bold alphabets in upper and lower case, plus bold digits. Because each bold letter is a separate character, rather than a plain letter with a style applied, LinkedIn has nothing to strip. It stores and displays the characters exactly as you pasted them.

This page swaps each selected letter for its bold counterpart from that block. Nothing is uploaded, and no LinkedIn login is involved: the conversion is a lookup that runs in your browser, letter by letter. Characters without a bold form, such as punctuation, emoji, accented letters and most non-Latin scripts, are left untouched, so your text never turns into replacement symbols.

LinkedIn renders posts in a sans-serif system font: San Francisco on Apple devices, Segoe UI on Windows and Roboto on most Android phones. Bold sans matches that look, so a bold phrase reads as natural emphasis rather than a different typeface. It is the right default for hooks, key numbers and short labels, and it is what the Bold button produces. The fonts page shows all thirteen styles side by side if you want to compare them before choosing.

Bold serif has small strokes at the ends of the letters, like a newspaper headline. It stands out more against the sans-serif body text, which makes it useful for a one-line title or a quotation, but it can look out of place mid-sentence. Use it sparingly and not alongside bold sans in the same post.

Bold italic and bold italic sans add slant on top of weight. They suit a single phrase you want to sound different, such as the name of a book or a line you are quoting, but a whole sentence of bold italic is tiring to read on a small screen.

Whichever you pick, stay consistent. A post that mixes three bold styles looks like a ransom note, and readers notice the noise before they notice the point.

Because the bold letters are ordinary characters, they paste into any LinkedIn field that accepts typed text. What changes from field to field is how much room you have and how much attention the field gets.

Posts

The obvious place. Bold the first line so the hook stands apart from the rest, or bold the one number that proves your point. Posts allow 3,000 characters, which is the only limit on this page that LinkedIn documents.

Comments

A short bold phrase helps your reply stand out in a long thread, especially when you are answering one part of a longer post. Comments are capped at roughly 1,250 characters by third-party measurements.

Headline

Your headline follows you into every comment you write and every search result you appear in. Bold one short phrase at most, and keep your job title plain so recruiters searching for it still find you. Headlines run to roughly 220 characters.

About and experience

Bold works well as section labels inside long profile text: what I do, selected results, how to reach me. Readers skim profiles, and labels give them handholds. The About section allows roughly 2,600 characters.

Messages and company pages

Bold can highlight a date or the one question you need answered in a message, and page admins can use it in company updates exactly as in personal posts.

The LinkedIn apps have no bold option either, but this page works in Safari on iPhone and in Chrome, Samsung Internet or Firefox on Android. On a phone the toolbar moves to the bottom of the screen and rises above the keyboard, so the Bold and Copy buttons stay under your thumb.

A practical routine on mobile: write the post in the editor here, bold the few words that matter, check the mobile preview to see where see more cuts it, press Copy, then switch to the LinkedIn app, start a post and paste. If you already drafted the post in the app, select all of it there, copy, paste it into the editor here, add the bold, and copy it back.

Current versions of iOS and Android include fonts for mathematical bold letters, so readers on recent phones see the bold correctly. A small number of older Android devices lack those fonts and show boxes, which is one more reason to bold phrases rather than paragraphs.

Bold is a signpost. Used well, it lets someone scrolling past understand your post from the bold words alone. These patterns work across most kinds of post.

1. Bold the hook, then leave a blank line. The first line decides whether anyone presses see more. Bold gives it weight and the blank line gives it space.
2. Bold one phrase per paragraph. A reader who scans only the bold phrases should still get the outline of your argument.
3. Bold the number, not the sentence. “Response time fell from four days to six hours” is stronger than a fully bold sentence, because the eye lands exactly on the evidence.
4. Use bold labels for structure. Short labels such as Problem, What we tried and Result at the start of a line turn a long post into sections without headings.
5. Bold the question you want answered. If you end with a question, bold it so people who skim to the bottom know how to reply.
6. Leave names, skills and hashtags plain. Search on LinkedIn and on search engines matches ordinary letters. A bold company name or skill will not be found.

The opposite habit, bolding everything that feels important, cancels itself out. When half the post is bold, nothing is.

Bold letters are not free. Before you paste, it helps to know the three trade-offs.

Character budget. Each bold letter is stored as two UTF-16 code units instead of one. LinkedIn’s post limit appears to count those units, so a post written entirely in bold would hit the cap at about half its usual length. The counter under the editor shows the visible count and the code units side by side, and the LinkedIn character counter counts your post against the 3,000-character limit and lists the limit for every other field.

Search. A bold word is a different string of characters from the plain word. LinkedIn search and search engines treat it as unrelated text, so bolded keywords do not help anyone find your post or profile.

Assistive technology. Screen readers handle these characters inconsistently. Some announce a name such as “mathematical bold capital A” for each letter, which turns a bold sentence into a long, confusing string. Keeping bold short protects readers who rely on them.

None of this means you should avoid bold. It means bold belongs on a handful of words per post, chosen on purpose.

Unicode’s bold alphabets cover the basic Latin letters A to Z, a to z and the digits 0 to 9. Letters with accents, such as é, ü or ñ, have no bold form in that block, and neither do Cyrillic, Arabic, Hebrew, Devanagari, Chinese or Japanese characters. The formatter leaves those characters exactly as they are, so a bolded French or German sentence will mix bold and regular letters.

Numbers bold cleanly, which makes them good candidates for emphasis: a date, a price, a percentage or a count. Punctuation and emoji are never changed (the symbols page has bullets, arrows and dividers that work as plain characters), and grouped emoji such as a family or a flag stay intact, because the formatter works on whole characters as you see them rather than on the code units underneath.
