LinkedIn About Section Character Limit & Structure
The 2,600-character ceiling, the 265-character reality, and a structure for the section most people fill with a CV summary nobody asked for.
The LinkedIn About section character limit is 2,600 characters. LinkedIn also calls this section the Summary, which is why half the internet searches for one name and half for the other — same box, same limit.
As with posts, the official limit is not the operative one. On desktop, visitors see roughly the first 265 characters before a "see more" link; on mobile it is less. Your opening three lines are the whole section for everyone who does not click, which is most everyone.
The numbers
| What | Limit | Notes |
|---|---|---|
| About / Summary total | 2,600 characters | Hard limit, including spaces and line breaks |
| Visible before "see more", desktop | ~265 characters | Approximate; roughly three lines |
| Visible before "see more", mobile | Less than desktop | Narrower column, earlier cut |
The fold figures are approximations — LinkedIn does not publish them and they shift with layout. Plan for the worst case.
What the About section is actually for
The default behaviour is to paste in a third-person biography: "Chris is a results-driven professional with 15 years of experience leveraging synergies…" Nobody has ever finished reading one of these. It is a cover letter addressed to no one, written in a voice you would never use out loud.
The section works better as an answer to the one question a profile visitor actually has: "Is this person relevant to me?" Who you help, what you help them with, and what to do next. First person, plain sentences, no adjectives that would appear in a performance review.
A structure that fits the limit
Two thousand six hundred characters is roughly 400 words — plenty, if you spend them in the right order:
Step 1
The hook (first ~265 characters)
The only part everyone sees. State who you help and the outcome, in first person, before the fold. If this paragraph works, the rest gets read; if it does not, the rest is furniture.
Step 2
The credibility paragraph
One short paragraph of proof: what you have done, for whom, with what result. Specifics only — numbers, names you are allowed to use, concrete outcomes.
Step 3
The how
What working with you or following you actually looks like. Services, topics you post about, the problems you take on. This is where the keywords live, worked into sentences rather than listed like ingredients.
Step 4
The call to action
One line. What should a reader do next — message you, follow you, visit a link? People end sections like this with a full stop and a prayer. Tell them what to do.
Keywords, without the stuffing
The About section is indexed by LinkedIn search, so the terms people would use to find someone like you belong in it. The trick is to place them in sentences a human would enjoy reading. A paragraph that mentions your speciality twice naturally does more for you than a comma-separated keyword dump, which reads as spam to humans and is not clever to algorithms either.
One placement note: your headline and current job title weigh more heavily in search than the About section, so treat this section as supporting evidence, not the primary keyword vehicle.
About section checklist
- Total under 2,600 characters
- First ~265 characters state who you help and the outcome

- Search terms worked into real sentences
- Ends with one clear call to action
- No "results-driven", no "passionate", no "leveraging"
Frequently asked questions
- What is the LinkedIn About section character limit?
- 2,600 characters, including spaces and line breaks. The same limit applies to the section LinkedIn calls the Summary — they are the same field.
- How much of the About section shows before "see more"?
- Roughly the first 265 characters on desktop, less on mobile. LinkedIn does not publish exact figures, so treat this as an approximation and front-load the important part.
- Is the LinkedIn Summary the same as the About section?
- Yes. LinkedIn renamed the Summary to About; the field and its 2,600-character limit are unchanged. People search for both names.
- Should my LinkedIn About section be in first or third person?
- First person. Third-person biographies read as detached and are a convention borrowed from conference programmes, where they also do not work.
- Does the About section affect LinkedIn search?
- Yes, it is indexed, but the headline and current job title carry more weight. Include your key terms naturally in sentences rather than as a keyword list.
