How to make every character count
Headline (220)
Use a formula: role, who you help, and the outcome. Put searchable keywords early. The headline is one of the strongest signals in LinkedIn search.
Post (3,000)
Win the first line. Only ~210 characters show before “see more,” so open with a hook or a bold claim, then break the rest into short, scannable lines.
About (2,600)
Lead with the problem you solve, not your job title. The first three lines are all most people see before expanding.
Connection note (300)
One specific reason you are reaching out beats a generic pitch every time. Reference something real: a mutual, a post, an event.
Frequently asked questions
What is the LinkedIn headline character limit?
The LinkedIn headline is capped at 220 characters. It appears under your name across the whole platform, so front-load the most important keywords and value.
How many characters can a LinkedIn post be?
A LinkedIn feed post allows up to 3,000 characters. However, only the first ~210 characters (fewer on mobile) show before the “see more” fold, so your hook needs to land in that first line or two.
What is the character limit for a connection request note?
When you can attach a note to an invitation, it is limited to 300 characters. Because LinkedIn has restricted free note-with-invite usage, keep the message short and specific so it earns the space.
How long can the LinkedIn About section be?
The About (summary) section holds up to 2,600 characters. Only the first ~3 lines show before “see more,” so lead with a strong opening the same way you would a post.
Does the counter handle emojis correctly?
It counts by Unicode code point, so a single emoji counts as one character, which matches how most LinkedIn fields behave. Complex multi-part emoji can still vary slightly on LinkedIn's side.
Is the LinkedIn character counter free?
Yes. It runs entirely in your browser, needs no signup, and there is no limit on how much text you can check.
