How Sentence Counting Works
Our sentence detection algorithm uses advanced pattern matching to identify sentence boundaries by recognizing terminal punctuation marks followed by whitespace. It handles complex edge cases like abbreviations (Dr., Mr., Mrs., etc.), decimal numbers (3.14), and ellipses (...).
The tool calculates average words per sentence by dividing total word count by sentence count. Sentences with 15-20 words are optimal for general audiences. The sentences per paragraph metric helps maintain balanced structure.
All processing happens instantly in your browser. No server upload occurs, ensuring complete privacy for confidential documents. The tool handles documents of any size with accurate sentence detection.
