The limits worth knowing
Character limits govern more writing than most people realise. A meta description is cut off around 155 characters and a page title around 60. A post on X allows 280. A LinkedIn post truncates behind a "see more" at roughly 210. SMS messages split at 160. Google Ads headlines allow 30 characters each.
Writing to a limit is much easier when the count updates as you type than when you paste into the destination, discover it is too long, and start cutting under pressure. Characters-without-spaces is the count some academic and translation contexts use, which is why both are shown.
How reading time is estimated
Reading time is word count divided by an assumed reading speed - typically 200 to 250 words per minute for adults reading online. It is an estimate and should be treated as one: dense technical writing reads slower, and a page full of code samples or tables breaks the model entirely.
It is still worth showing, because it is what readers respond to. A "12 min read" label sets an expectation, and knowing the number before you publish tells you whether an article that felt tight is actually asking for a quarter of an hour.
Word count and SEO
Length is not a ranking factor, and no threshold exists that makes a page rank. What is true is that comprehensive pages tend to be longer, because covering a topic properly takes words - the length is a symptom of thoroughness, not a cause of ranking.
The useful application is comparative. If everything ranking for your target query runs to two thousand words and your draft is four hundred, you are probably not answering the question as fully as the reader expects. Padding to hit a number achieves nothing.
Frequently asked questions
- Is my text sent anywhere?
- No. Counting happens entirely in your browser. Nothing is uploaded or stored, so an unpublished draft stays yours.
- How is reading time calculated?
- Word count divided by an average online reading speed of roughly 200 to 250 words per minute. It is an estimate, and dense technical material reads more slowly.
- What is a good meta description length?
- Around 120 to 155 characters. Google truncates longer descriptions in results, so the important part should come first regardless.
- Does word count affect SEO rankings?
- Not directly. Longer pages often rank better because thorough answers take more words, but adding words without adding substance does nothing.
