See exactly how your content looks on LinkedIn, including where the "see more" fold appears on desktop and mobile.
Character count tells you whether the post fits. Formatting tells you whether it scans. After you check the preview and "See more" cutoff here, use the free LinkedIn text formatter to add light bold text, bullets, arrows, or dividers before you paste the final version into LinkedIn.
Keep the first line mostly plain, then use formatting only where it helps a reader understand the structure faster. That combination keeps the post readable while still giving busy prospects visual anchors.
LinkedIn posts can be up to 3,000 characters long. This limit was increased from 1,300 characters in June 2023 and remains unchanged in 2026.
It depends on the content type and device. For posts with images or video, LinkedIn truncates at roughly 210 characters on desktop and 140 on mobile. Text-only posts get more room: about 480 characters on desktop before the fold. The cutoff is technically line-based, so exact numbers vary slightly with word length and formatting.
Your LinkedIn headline can be up to 220 characters. However, only about 60-70 characters display in search results, connection cards, and comment sections. Write the most important part first.
Yes. Every character counts, including hashtags, emojis, spaces, and line breaks. Each emoji counts as one or more characters depending on the emoji.
Research suggests 1,200-1,500 characters performs best for engagement. But the most important thing is your hook: the first 140-210 characters that show before the "see more" button. If your hook doesn't stop the scroll, post length doesn't matter.
