Why They Should Be Different
Many professionals copy their resume summary directly into LinkedIn and vice versa. This is a strategic mistake. The two documents serve fundamentally different purposes and are read by readers in very different mental states. A resume lands in front of a recruiter who has already decided to evaluate you — they are in assessment mode. A LinkedIn profile is discovered by someone who was not necessarily looking for you — they are in exploration mode. The writing that works for one mode is actively counterproductive for the other.
Our free LinkedIn About Section Generator can help you apply these principles directly to your own profile in seconds.
Tone and Voice Differences
Resume summaries use formal, concise, third-person-adjacent prose and avoid personal pronouns in most professional traditions. They are tightly keyword-matched to the specific job posting. They use numbers and achievements almost exclusively. LinkedIn summaries are first-person, conversational, and personality-forward. They can include opinions, context, and narrative that a resume never would. A resume says "Managed a team of 12 across three time zones"; a LinkedIn About says "I built the team from nothing — wrong hires early taught me more about management than any book."

Content Differences
Resume summaries contain role-specific keywords pulled from the particular job description. They are often re-written for each application. They avoid any content that could date poorly — references to trends, current tools, or time-sensitive projects — because the resume may be reviewed weeks after submission. LinkedIn About sections can and should be more current, specific, and opinionated. Include your current interests, where you are actively learning, and what types of projects or problems you want more of — none of which belongs on a formal resume.

Length and Format Differences
Resume summaries run 2–4 sentences or 50–80 words — enough to anchor the reader before they move to experience. LinkedIn About sections can run 150–400 words with line breaks, since they are designed to be read in the context of a full profile. Formatting differences: resumes use dense paragraphs or bullet points within the summary; LinkedIn About sections use short paragraphs with white space for mobile readability. Emojis are acceptable in some LinkedIn About sections (particularly for consumer-facing or creative roles) but never in resumes.

How to Write Each One
Write your LinkedIn About first — it is longer, more personal, and forces you to think about your career narrative without constraint. Then extract the most impactful two or three sentences, strip out personality and narrative, add the specific keywords from the target job description, and tighten it until it is under 80 words. That is your resume summary. The two documents should feel like they come from the same person but are calibrated for their specific audience and context.

FAQ
Frequently Asked Questions
What should I write in my LinkedIn About section?
Open with a hook, follow with your professional background, key achievements with numbers, core skills, and a clear call-to-action. Write in first person and focus on the value you bring.
How long should a LinkedIn summary be?
Ideal is 150-300 words. LinkedIn truncates after ~300 characters with "see more", so your opening must be compelling enough to earn the click.
Should I write in first or third person?
Write in first person ("I"). It feels more personal, authentic, and approachable. Third person sounds overly formal on LinkedIn.
