LinkedIn caption limit: 3,000 characters · Feed preview truncates after ~140 characters on mobile, ~210 on desktop. SherpaPost shows the exact cutoff and line breaks before you publish.
A LinkedIn post preview is a mockup of how a post will appear in the LinkedIn feed before you publish — your name and headline, the body text with its 'see more' truncation at ~140 characters on mobile (~210 on desktop), document carousel covers, and link unfurls. SherpaPost reproduces the exact cutoff so the hook still earns the click on a phone screen, where most LinkedIn views actually happen.
LinkedIn allows up to 3,000 characters per post, but the feed collapses everything after ~140 characters on mobile (slightly longer on desktop) behind a 'see more' link. Long-form posts work well on LinkedIn — they just need the first two lines to do the persuading. SherpaPost marks the cutoff line and previews how the post looks both collapsed and expanded.
LinkedIn's composer shows you a rough draft view, not the feed view — line breaks, mention rendering, and link card layout often look different the moment you publish. SherpaPost previews the feed-rendered version, lets you A/B different hooks side by side, and uses AI to rewrite drafts in a more credible, less corporate voice. You still publish from LinkedIn — no API connection required.
