LinkedIn Post Character Limits (2025)
LinkedIn posts: 3,000 characters. Only the first ~210 characters display before "see more" on desktop (~140 on mobile). Hook readers in the first two lines with a bold statement or question.
LinkedIn Articles: 125,000 characters (~20,000 words). Articles are long-form content that lives permanently on your profile. Ideal length is 1,500-2,000 words for best engagement.
LinkedIn Comments: 1,250 characters. Commenting is the most underrated LinkedIn growth strategy — thoughtful comments on popular posts can drive significant profile visits.
