Sentence Counter
Sentence count is the fastest readability signal a writer has. This tool counts sentences as you type and puts them next to words, paragraphs, lines and reading time, so you can tell at a glance whether a paragraph is getting too dense.
It recognizes the punctuation that actually ends sentences in mixed-language text: Latin periods, question and exclamation marks, plus the full-width 。!?… used in Chinese and Japanese.
Frequently asked questions
What counts as a sentence?
Any stretch of text ending in a period, question mark, exclamation mark or the CJK equivalents 。!?… — as long as it contains something other than whitespace.
Why does my count differ from my editor's?
Abbreviations like 'Mr.' or 'e.g.' end with a period and are counted as sentence ends — this tool uses punctuation rules, not full natural-language parsing.
How many sentences should a paragraph have?
Style guides commonly suggest 2–5. There is no rule set in stone: use the count to spot walls of text before your readers do.
