Frequently Asked Questions

How does the sentence counter detect sentences?
The sentence counter splits text at periods, exclamation marks, and question marks followed by whitespace or end of text. Abbreviations like Mr. and Dr. are handled to avoid false splits. Each non-empty segment is counted as one sentence.
What is a good average sentence length for academic writing?
For academic writing, an average sentence length of 15 to 25 words is generally recommended. Sentences shorter than 10 words may feel choppy while sentences over 35 words can be hard to follow. Variety in sentence length improves readability.
What counts as a run-on sentence?
A run-on sentence occurs when two or more independent clauses are joined without proper punctuation or conjunctions. This tool flags sentences over 40 words as potentially long or run-on sentences that may benefit from being split.
How can I improve sentence variety in my writing?
Aim for a mix of short, medium, and long sentences. If your average sentence length is over 25 words, try splitting some sentences. If it is under 12 words, combine some shorter sentences. Varying structure and starting words also helps.
