About the Sentence Counter
This sentence counter counts the sentences in a text, reports the average length, and lists each sentence separately so overlong ones are easy to find. Abbreviations and decimals are handled so they do not split a sentence incorrectly.
A sentence counter is an editing tool more than a counting one. Average sentence length is one of the strongest signals of how readable prose is — much above 25 words and text starts to feel heavy no matter how simple the vocabulary.
Listing sentences individually is where the value sits. A good average can hide a 60-word monster next to several short ones, and seeing them separately makes the offender obvious. Variety matters too: alternating short and long reads far better than a uniform stream.
Detection is not naive full-stop splitting. Abbreviations such as Dr. and e.g., decimal numbers, and ellipses all contain periods that do not end a sentence, and are treated accordingly.

Frequently asked questions
How does it decide where a sentence ends?
By sentence-ending punctuation, while allowing for abbreviations, decimals and ellipses that contain periods but do not end a sentence.
What is a good average sentence length?
Roughly 15 to 20 words for general readability. Consistently above 25 makes prose feel heavy regardless of vocabulary.
Why list each sentence separately?
A reasonable average can hide one 60-word sentence. Seeing them individually makes the problem sentence obvious.
Does it handle abbreviations like Dr. correctly?
Yes. Common abbreviations are recognised so they do not split a sentence at the wrong point.
