Why previewing your post before you publish matters
LinkedIn's composer is a plain text box. It does not show your avatar next to the post, where an image will crop, or how much of your writing survives before "...see more" folds the rest away. You find out how the post reads only after it is live, when the first readers have already scrolled past.
The cut is the biggest lever in the mockup: roughly 210 characters on desktop and around 140 on mobile. Since most LinkedIn reading happens on phones, adjust the first two or three lines until they land as a complete thought on the tighter mobile cut.
Your headline and avatar sit next to every post
The name, the 220-character headline and the avatar appear directly above every post you publish. A placeholder avatar or a stale headline can undercut a strong post before anyone reads a word, so the preview lets you fill them in and see the whole card. Text styled with a Unicode formatter renders here exactly as it will in the feed.
