How the sentence counter works in a Paragraph?
Simple rule is that if you want to count sentences in a paragraph yourself, then count every period, question mark, and exclamation point. In reality, it is not always that simple, since there are lots of periods that are not sentence terminations.
- Start right after any capital letter that begins a new thought.
- End at a period, question mark, or exclamation point (or a mix, like “?!”).
- Note that abbreviations such as Mr., Dr., e.g., and U.S. have periods that do not end sentences.
- Be alert for decimals such as 3.14 or 12.5 (period is within the number, not a sentence break).
- Be aware of ellipses (scattered dots “…”) that may run on rather than stop a thought.
It’s a tedious, time-consuming task and prone to error task for a long document, and that’s where a sentence counter comes into the picture. Copy and paste your paragraph into the tool above and it will apply the same rules automatically each and every time!

Frequently Asked Questions
How exactly count as a “sentence”?
A sentence is a piece of text that ends with a period, question mark or exclamation mark (or a combination, such as “?!”) The tool is also designed to look for common abbreviators, decimal numbers and ellipses, to avoid confusing them with sentence ends
Is this sentence counter really free to use?
Yes. It’s a completely free sentence counter with no sign-up, no word limit, and no watermark.
Does this tool store or upload my text?
No, it is done entirely in your browser, via JavaScript. Nothing is sent to a server, logged, or saved — when you close the tab, it’s gone.
Does Google Docs have a built-in sentence counter?
Not yet available — Google Docs shows a word and character count, but not a sentence count. Paste the text copied from Docs here to get a live sentence count along with all your other statistics.
Why does my count differ from other online counters?
Most basic tools count every period and a sentence with “Dr.” or “e.g.” or a decimal such as “4.5” is incorrectly counted as two or three sentences. This tool attempts to identify them in order to more accurately represent actual sentences. For truly ambiguous text, small variations in tools are still normal.
What’s a good average sentence length?
While there is no magic number, many style guides would recommend the average of around 15-20 words per sentence for easier reading.
Will I be able to use it on my phone as a sentence counter app?
Yes. It’s designed for mobile first, meaning all controls have been sized and spaced for touch screen usage and grow larger for tablet and desktop.
