LinkedIn Post Preview

LinkedIn truncates posts in the feed after approximately 3 lines of text (around 210–220 characters on desktop, depending on line breaks and font rendering). The exact cutoff varies slightly by screen width and device. The preview in this tool reflects the LinkedIn desktop feed layout as closely as possible so you can judge where your readers will see the fold.

The lines before 'see more' are the only content a reader sees without clicking. If your hook (your most interesting or provocative sentence) falls after the fold, most people will scroll past without engaging. Optimising the opening lines to land before the fold is one of the most useful things you can do to increase reach on LinkedIn.

LinkedIn allows up to 3,000 characters for regular posts. Articles have no character limit. The character counter in this tool shows your current count against the 3,000-character limit in real time.

For regular posts, LinkedIn uses a straightforward character count: each Unicode code point counts as one character (emoji may count as 1 or 2 depending on how LinkedIn normalises them). This differs from X (Twitter), which uses a weighted system where URLs are 23 and CJK characters are 2. The counter in this tool uses the standard character count that matches LinkedIn's display.

This tool focuses on text post previews, which is where the 'see more' fold and hook optimisation matter most. Image and video previews depend heavily on file dimensions and compression, which a browser-based tool can't replicate with full accuracy. For media previews, Postopus (the full app) shows native previews including media grids, carousels, and documents.
