LinkedIn Character Limit Tips

Posts cap at 3,000 characters

LinkedIn feed posts are limited to 3,000 characters. Posts are truncated after about 210 characters on mobile, so your opening line must hook the reader into tapping "see more."

Your headline is your elevator pitch

LinkedIn headlines allow 220 characters and appear everywhere your name shows up. Go beyond your job title and include keywords that describe what you do and who you help.

Articles have nearly unlimited space

LinkedIn articles support up to 125,000 characters, which is roughly the length of a short book. Use articles for in-depth thought leadership, case studies, and long-form guides.

Comments drive visibility

LinkedIn comments can be up to 1,250 characters. Thoughtful, detailed comments on popular posts are one of the fastest ways to grow your reach on the platform.

Company page taglines are short

LinkedIn company page taglines are limited to 120 characters. This appears directly below your company name, so craft a clear, benefit-driven statement about what your company does.
