Frequently Asked Questions About Sentence Counter
How does the tool detect sentences?

What is a good average sentence length?
For general writing, 15-20 words per sentence is considered ideal. Academic writing averages 20-30 words. For web content, 10-15 words is recommended for readability.
Does it count headings and bullet points?
Yes. All text is analyzed including headings, bullet points, and any line of text. Each line ending with . ! or ? is counted as a sentence.
