LinkedIn Character Limits: Complete Reference

People search for one number. LinkedIn has several, and they do different jobs.

A post can look fine in your draft doc and still fail for three separate reasons: the feed cuts the preview early, the expand happens later than you expected, or a profile field refuses to save because you went over a hard cap.

This guide collects the limits creators usually mean when they say "how long can a LinkedIn post be," plus the profile and messaging caps that trip people up less often. Treat every figure as commonly observed or widely cited, not as a permanent API contract. LinkedIn ships UI changes without a press release. When a field rejects your paste, the composer is the source of truth.

If you only remember one habit: write for the first screen someone sees, then check the full count before you publish.

For standard text posts, two numbers matter more than the rest.

See more: many feed surfaces show a truncated preview and a see more control somewhere around 1,300 characters. That is the marker the free counter at linkedinpost.ai/tools/linkedin-character-counter is built around. Crossing it is normal. Strong posts often put the payoff after the fold on purpose. The failure mode is filling those first 1,300 characters with throat-clearing so the visible part never earns a click.

Practical ceiling: creators and tools often plan against about 3,000 characters for a standard post. That is a working upper bound for drafting, not a promise that every surface accepts exactly that length forever. If your draft is climbing past that range, ask whether it wants to be a tighter post, a carousel, or LinkedIn's longer article-style formats instead of one endless wall of text.

Historically, some feed previews also felt very short in the first lines people saw, closer to a tweet-length glance before expand. Even when the formal see more sits later, mobile readers decide from the opening beat. Put the conflict, number, or claim in the first two or three lines.

Spaces, line breaks, and Unicode styling still count. Fancy bold characters from a formatter do not get a free pass on length.

Comments are tighter than posts. A commonly cited ceiling sits around 1,250 characters. LinkedIn has adjusted comment behavior over the years, so if a long reply fails to send, shorten it and try again rather than assuming your memory of the limit is current.

In practice, you rarely need the full allotment. The comments that get replies tend to add one specific point, a question, or a short story, not a second essay under someone else's post.

If you are writing a thoughtful reply that keeps growing, consider whether it should be your own post with a link back, or a two-part comment where the first part stands alone if the rest gets cut.

Agencies and social teams: keep a comment style guide shorter than your post guide. "Add one concrete detail" beats "leave a thoughtful comment" when junior writers are racing through engagement tasks.

Your headline is one of the most scanned lines on LinkedIn after your name. The widely cited limit is 220 characters. That sounds generous until you try to fit role, who you help, and a proof point without sounding like a keyword dump.

Write the human sentence first, then trim. "Founder at X | helping Y do Z" works when Y and Z are specific. Stacking five job titles and a motivational quote usually wastes the space people actually read.

Name fields are stricter. First and last name caps are small (often discussed in the ballpark of a few dozen characters each, with first name especially tight). LinkedIn also polices symbols and keyword stuffing in names. If you are tempted to put "| Open to work | SaaS" in your last name, expect friction, and expect readers to trust you less even if it saves.

Company page names, job titles in Experience, and education fields have their own shorter ceilings. When an edit will not save, count the field you are in rather than assuming the post limit applies.

The About section is commonly capped around 2,600 characters. That is enough for a clear story and a soft call to action. It is not enough for your full career narrative pasted from a resume.

A structure that tends to read well:

one short paragraph on what you work on now

one on who should reach out and why

a few proof points or topics you post about

Front-load the useful part. Many people never hit see more on a profile summary either. If your best sentence is in paragraph four, move it up.

When you import a profile into a drafting tool, headline and About are the fields that shape how AI (or a junior writer) talks about you. Keep them accurate and current. Stale About copy produces stale drafts.

Direct messages and InMail are a different product surface from the feed, and LinkedIn has changed caps here before.

Connection note requests are short by design. You get a small window to say why you are reaching out. Use it for one clear reason, not a pitch deck.

Regular messages and InMail bodies are often discussed around the high hundreds to roughly 1,900 characters, with InMail subjects cited near 200 characters. Treat those as planning numbers. If a message will not send, shorten the body and retry. Fancy formatting that works in a post may not paste cleanly into a message box.

For outreach, shorter almost always performs better than burning the full limit. One specific observation about their work beats three paragraphs about your company.

If you send the same template at full length to fifty people, length is not your real problem. Relevance is.

LinkedIn is a product, not a standards body. Limits change when the company ships new composers, tests mobile layouts, rolls out articles or newsletters, or adjusts spam controls.

Third-party blog posts (including older ones that still rank) freeze a number in time. Your feed may already disagree.

Surfaces also differ. A personal profile post, a Company Page post, a comment, a newsletter, and an API-scheduled update are not guaranteed to share one ceiling. Creators talking about "the LinkedIn limit" are usually talking about the personal feed post they publish by hand.

Encoding surprises add noise. Emoji, zero-width characters, and Unicode bold or italic alphabets can make two drafts that look the same length count differently. If a counter and LinkedIn disagree by a handful of characters, check for hidden characters before you assume the published limit changed overnight.

Best practice: keep a small internal cheatsheet for your team, date it, and re-verify quarterly against the live composer. Do not build a client deliverable that depends on a blog post from 2019.

When you care about the see more fold or a practical post ceiling, use the free tool at linkedinpost.ai/tools/linkedin-character-counter.

Paste your draft. You get a live character count (spaces and line breaks included), a word count, and a rough line estimate. The progress bar is keyed to the ~1,300 see more marker. Cross it and the truncated panel shows what a feed reader is likely to see before expand. The full panel stays beside it so you can compare without guessing.

A simple three-pass edit works well here. First, get the story down without worrying about length. Second, fix the opening so the truncated preview still makes sense alone. Third, cut middle filler so the expand rewards the click.

Nothing in that tool requires signup, and the count runs in your browser. Clear the field on a shared computer when you are done.

If you also use Unicode bold or bullets, format first, then paste back into the counter. Styled characters still count toward the total.

Pair length checks with hook practice. A perfect character count with a soft opener still loses. When the fold looks right but the first lines feel generic, fix the hook before you obsess over shaving twenty characters.

Run this when a draft is almost ready:

1. Does the first screen state a specific tension, result, or claim? 2. If see more appears around 1,300 characters, does the visible part earn the expand? 3. Are you under a sensible planning ceiling near 3,000 for a standard post, or should this become a carousel or article? 4. Did Unicode styling or emoji inflate the count in a way LinkedIn will also see? 5. For profile edits: are headline and About inside their field caps, with the useful sentence first? 6. For outreach: can you cut the message in half and keep the one reason you wrote?

If you only do one thing, paste the post into linkedinpost.ai/tools/linkedin-character-counter and read only the truncated panel. If that panel would not make you click your own name, rewrite the top before you publish.
