Where this data comes from
The sources and check dates in this table come from one versioned data file — the place we record every check we make. The rest of this page, and the limits built into our tools, are still separate copies, so when we correct a figure we correct it in each place. This table is how we keep ourselves honest while we do.
We've checked some of these figures, not all of them yet
Some figures on this page have been checked against the platform's own documentation — those show a source and the date we checked. The rest came across from our older pages and haven't been checked yet, so they say so. We'd rather show you which is which than print a date we haven't earned.

3,000 |
Standard feed posts. Confirmed via LinkedIn Help (2026-09-19): "The character limit for a post is 3,000 characters." The same page states that exceeding 3,000 characters is the trigger for writing an Article instead. |

| Article |
125,000 |
LinkedIn's built-in publishing platform. LinkedIn Help states exactly: "Articles are typically longer than posts and are limited to 125,000 characters." The reference page's ~120,000 figure has no LinkedIn source anywhere found in this pass; it appears to be a third-party estimate. A separate LinkedIn Help page ("Tips for writing articles", linkedin.com/help/linkedin/answer/a516913) contradicts this by stating "There are no limits on word count" — LinkedIn's own docs are not fully consistent with each other, but 125,000 is the only figure LinkedIn itself publishes as an exact character limit. |

| Headline |
220 |
The tagline below your name. Checked LinkedIn Help pages for editing your headline and profile overview (a542926, a564064, a546603) directly — none publish a character count for this field. 220 could not be verified against any LinkedIn primary source; it circulates only via third-party SEO content. |

| About / Summary |
2,600 |
Your profile summary section. Checked LinkedIn Help profile-editing pages (a546603, a564064) directly — no character count is published for the About/Summary section. Could not verify against a LinkedIn primary source. |

| Comment |
1,250 |
Comments on posts and articles. Confirmed via LinkedIn Help's "General limits for LinkedIn groups" page, which publishes a limits table including "Character limit for comments: 1250". This is the only place LinkedIn documents a comment character limit; the page is framed around Groups but the limits table is presented as general. |

| Connection Note |
300 |
The message when sending a connection request. POSSIBLY STALE. LinkedIn Help's most recently updated page on this ("Personalize invitations to connect", a563153) states flatly: "Each message can be up to 200 characters" — no Premium exception. An older LinkedIn Help page (a6239760, "Differences between InMail Messages and personalized invitations") states the free-tier limit is 200 and Premium members get up to 300. Since the newer page is silent on any Premium exception, 300 may no longer apply. Flagged for Bill: this record still publishes 300; LinkedIn's current guidance may be 200 for all accounts. |

| Company Page Description |

| First Name |

Profile first name field. LinkedIn Help's "Names allowed on profiles" page (a1337288) covers naming policy only (no pseudonyms, real name required) and publishes no character count. Could not verify against a LinkedIn primary source. |

| Post — characters visible before truncation on desktop |
210 |
A display-truncation figure, not a hard limit. Published only in the social-media limits guide. Confirmed this is genuinely undocumented by LinkedIn: no linkedin.com/help page describes "see more" truncation behaviour at all. Every source for ~210 is a third-party tool or blog. Left unverified rather than inventing a source. |

What we corrected
This page used to give LinkedIn articles roughly 120,000 characters. LinkedIn's own Help Centre says 125,000, so we've corrected it.
