Only about 210 characters show on mobile before the "see more" link. That first sentence is your only guaranteed impression — treat it like a subject line.
LinkedIn shows ~270 characters of your About section before truncating. Most profile visitors never click to expand, so your opening line has to do all the work.
Your 220-character headline shows in full across the feed, search, comments, and connection requests. It is your highest-leverage profile field.
The 8,000-character DM limit is generous. Aim for under 500 characters in outreach — long messages signal effort but low relevance.
You get one 300-character shot at a connection note. Skip the generic intro. Reference their content, a shared context, or a specific reason you are connecting.
At 1,250 characters, comments give you enough room to add genuine insight. Thoughtful comments on your prospects' posts build more recognition than cold outreach.
LinkedIn posts allow up to 3,000 characters. On mobile, only about the first 210 characters show before the "see more" link — so your hook needs to land in that window. On desktop feeds, the truncation point is slightly more generous at around 700 characters.
Your headline can be up to 220 characters. It appears under your name in the feed, in search results, on every comment you leave, and on connection requests — making it the most-seen line on your entire profile. Lead with who you help and the outcome you create, not just your job title.
Connection request notes are capped at 300 characters. The best ones are short, reference something specific about the person or their content, and never pitch. Two tight sentences outperform a full paragraph nearly every time.
InMail subject lines allow up to 200 characters and the body allows up to 2,000 characters. In practice, shorter InMails (under 400 characters in the body) consistently get higher reply rates. Use the extra space only if the context genuinely requires it.
Yes — spaces, line breaks, and punctuation all count toward the limit. Most emoji count as one or two characters depending on the symbol. The counter tool on this page counts the same way LinkedIn does.
The About section (formerly Summary) allows up to 2,600 characters. However, only the first ~270 characters show before the "see more" link. Front-load your most important value proposition in those first few lines — most people never click to expand.
