How the Sentence Counter Works
The tool detects sentence boundaries using terminal punctuation: periods (.), exclamation marks (!), and question marks (?). It also handles abbreviations, decimals, and ellipses to avoid false positives. The word count uses whitespace splitting, and paragraphs are counted by double line breaks.
What Is Average Sentence Length?
Average sentence length (ASL) is a common readability metric. A lower ASL generally means easier-to-read text. Academic writing often targets 20–25 words per sentence, while web copy aims for 15–18 words for better engagement.
Does it count questions and exclamations as sentences?
Yes — any text ending in
., !, or ? is treated as a sentence boundary.Are abbreviations like "Dr." counted as sentences?
The tool uses smart detection to skip common abbreviations so they don't inflate your sentence count.
What is a good sentence length?
For web content, aim for 15–20 words per sentence. Academic texts may go higher; children's books much lower.
Can I analyze very long texts?
Yes — the tool runs entirely in your browser and handles large texts without any server upload.
