Find the sentences people will skip, and make your post easy to read on a phone.
73/100
Grade 6 · Easy for an 11-year-old
1 paragraph runs past 300 characters or 3 lines. On a phone that looks like a wall.
Try: Break after every one to three sentences. Blank lines are free.
6 paragraphs with blank lines between them. Easy to skim.
1 sentence is over 25 words. Readers lose the thread before the full stop.
Try: Split at “and”, “but” or “which”. Two short sentences beat one long one.
2 sentences are hard to read because of length and long words. They’re highlighted in your text.
Try: Cut extra words, swap long words for short ones, or split the sentence.
5 uses of passive voice. It hides who did what and adds words. A little is fine.
Try: Say who did it: “was caused by the roadmap” becomes “the roadmap caused”.
4 adverbs. Words like “really” and “actually” often add little.
Try: Cut the adverb, or pick a stronger verb: “ran quickly” becomes “sprinted”.
3 words with a plainer swap. Plain words sound like a person, not a press release.
Try: Use the swap, or say it the way you would to a friend.
2 long words. Fine when it’s the right word.
Scores use the Flesch formulas, which count words, sentences and syllables. They can’t judge your idea. Keep what sounds like you.
People read LinkedIn on their phones, in a queue, between meetings. They skim. A long sentence full of words like “leverage” and “facilitate” loses them halfway, no matter how smart the point is.
This free readability checker scores your LinkedIn post for reading ease and grade level, then shows you exactly where it gets hard: long sentences, paragraphs that turn into a wall on mobile, passive voice, extra adverbs and corporate words, with a simpler word for each. Fix the red bits and check again.
The reading ease score runs from 0 to 100. Higher is easier. For LinkedIn, aim for 60 or above, which is plain English most adults read without effort. The grade level is the school year someone would need to follow you easily. Grade 8 or under is a good target for the feed.
This isn’t dumbing down. The smartest people you follow write simply. Simple is just faster to read.
Short sentences. If a sentence runs past 25 words, split it. Short paragraphs. On a phone, three lines of desktop text become six or seven, so break paragraphs early and leave blank lines between them.
Plain words. Use “use”, not “utilise”. Say “help”, not “facilitate”. And name who did what: “We shipped it” reads faster than “It was shipped by the team”.
Tip: Read your post out loud. If you run out of breath, so will your reader.
Most hard-to-read posts aren’t hard because of the idea. They’re hard because of the words. Utilise becomes use. Leverage becomes use. Facilitate becomes help. Commence becomes start. In order to becomes to. At this point in time becomes now.
The checker flags these as you type and shows the simpler word next to each one. Swap them, read the sentence again and you’ll see it gets shorter and clearer at the same time.
Keep the technical words your readers actually use. If you write for developers, “API” isn’t jargon. It’s just the word.
An easy post still needs an opening that earns the click. Test yours with the LinkedIn hook checker. If you used AI to draft it, the AI writing checker flags phrases that make it sound machine-made.
Then format and preview the final version in the LinkedIn post formatter.
A Flesch reading ease of 60 or higher, or a grade level of 8 or lower. That’s plain English most people read comfortably on a phone.
Reading ease and grade level use the Flesch and Flesch–Kincaid formulas, based on sentence length and syllables per word. The other checks, like passive voice and long paragraphs, are simple rules that run in your browser.
Not directly. LinkedIn doesn’t score your reading level. But posts that are easy to read get read to the end more often, and that’s what leads to comments and shares.
No. Everything runs in your browser. Your draft stays on this device.
The formulas and word lists are built for English. Scores for other languages won’t be accurate.
Wiral turns a thought, a voice note or a link into three posts that sound like you, with images and carousels built in. You pick one, it goes in your queue.
