Frequently Asked Questions
What is a good average sentence length?
+Most writing experts recommend 15 to 20 words per sentence for general readability. Under 20 words is easy to read. Between 20 and 30 is moderate. Over 30 words becomes difficult for most readers to follow in one reading.
How does the counter detect sentences?
