Optimal Social Media Character Limits for Maximum Engagement

Twitter / X (71 - 100 chars sweet spot)

While the hard character limit is 280, tweets between 70 and 100 characters receive 17% higher engagement rates due to faster mobile readability.

LinkedIn (100 - 150 words sweet spot)

LinkedIn gives 3,000 characters, but posts with a strong 2-line hook before the "...see more" fold achieve 4x higher dwell time and organic feed distribution.
