Word Counter
Count words, characters with and without spaces, sentences and paragraphs as you type, plus reading time and average word length.
SerpPrism's Word Counter is a free online tool that counts words, characters (with and without spaces), sentences and paragraphs in any text you paste, and adds the two numbers writers actually plan with: estimated reading time and average word length. There is no sign-up and the text never leaves your browser — the counting happens locally as you type. It is built for writers, students and editors working to a limit: an essay brief, a form field with a character budget, a speech that has to fit five minutes. Paste your text and every count updates on each keystroke, so you can trim against the number instead of guessing where you stand.
How to use it
- Paste or type your text into the box — every count updates on each keystroke.
- Read the grid: words, characters both ways, sentences, paragraphs, reading time, average word length and unique words.
- Edit against the number you care about. The counts follow along, so you stop when you hit the limit rather than after.
Why two character counts
Character limits are ambiguous in a way word limits are not. Some forms and briefs count spaces, some do not, and the two totals for the same text can differ by fifteen percent — easily the difference between a submission that fits and one that is rejected by a form validator. Showing both numbers side by side removes the guesswork: whichever convention your limit uses, you can see it.
The gap between the two numbers is also diagnostic. It is exactly your space count, so if it looks large next to the word count, the text probably carries double spaces or formatting pasted in from a word processor — invisible in the editor, visible here.
How the reading time is estimated
The estimate uses 200 words per minute, a widely used average for adult silent reading of non-fiction. Real readers range from roughly 180 to 250 words per minute depending on the material, and reading aloud is slower — around 130 words per minute, which is the number to use if you are timing a speech or a script.
Treat the figure as a planning number, not a promise. Dense technical text reads slower than its word count suggests, and a page with headings, lists and images gives the eye places to rest that a wall of paragraphs does not.
What counts as a word, a sentence, a paragraph
A word is a run of characters containing at least one letter or digit, so 'state-of-the-art' counts once and a stray dash counts never. A sentence ends at a full stop, question mark or exclamation mark — which means abbreviations like 'e.g.' inflate the sentence count slightly, and any tool that claims otherwise is hiding the same problem. A paragraph is a block of text separated by a blank line.
These conventions are why two counters disagree by a handful of words on the same text. The differences are definitional, not errors. What matters is that you measure the draft and the final version with the same ruler.
Questions
Is my text uploaded or saved?
No. Counting runs as JavaScript in your browser. Nothing you paste is sent to a server, stored, or logged — close the tab and it is gone.
How is reading time calculated?
Word count divided by 200 words per minute, the standard average for silent reading. For a speech or presentation, divide by roughly 130 instead — speaking is slower than reading.
Why does this count differ from Word or Google Docs?
Tokenisation. Tools differ on hyphenated words, numbers with commas, and words joined by em dashes. A difference of one or two percent between counters is normal and definitional, not a bug in either.
How are characters counted?
By JavaScript string length. Most letters count as one; some symbols and most emoji count as two, because they are stored as a pair of UTF-16 code units. If a platform rejects your text over a handful of characters, emoji are the usual reason.
What is a good average word length?
Ordinary English prose averages around 4.5 to 5 letters per word. Noticeably higher usually means jargon or nominalisations are piling up; noticeably lower can read as choppy. It is a texture check, not a target.
How do I check the readability of the same text?
Paste it into the Readability Score Checker — it grades sentence length, reading ease and passive voice, and names the specific sentences dragging the score down. Word count tells you how much text there is; readability tells you how hard it works the reader.
