About

Writing is more than just putting words on a page; it is about rhythm, flow, and clarity. A common pitfall in modern writing is the overuse of complex, run-on sentences that exhaust the reader's cognitive load. This tool acts as a structural MRI for your text, going far beyond simple counting.

Unlike basic counters that mistakenly treat abbreviations like Dr. or U.S.A. as sentence endings, our engine uses a comprehensive linguistic database to distinguish between structural punctuation and titular abbreviations. This ensures that your average sentence length - a critical metric for SEO and academic grading - is calculated with precision.

We employ the Flesch-Kincaid and Gunning Fog algorithms to quantify readability. Whether you are crafting a PhD thesis or a marketing email, knowing your grade-level complexity allows you to tailor your voice to your specific audience.

Formulas

The tool calculates the Flesch-Kincaid Reading Ease score using the following standard equation:

206.835 − 1.015 × Total WordsTotal Sentences − 84.6 × Total SyllablesTotal Words

Simultaneously, the Gunning Fog Index estimates the years of formal education needed to understand the text:

0.4 × Total WordsTotal Sentences + 100 × Complex WordsTotal Words

Frequently Asked Questions

Most basic tools count every period (.) as a new sentence. This is incorrect. Our tool recognizes over 200 common abbreviations (e.g., "Mr.", "e.g.", "Ph.D.", 'Jan.') and ignores periods used within them. This results in a lower, but far more accurate, sentence count.

In the context of the Gunning Fog Index, a complex word is defined as any word containing three or more syllables, excluding proper nouns, familiar jargon, or compound words formed from simple words.

This is our Visual Rhythm guide. Sentences highlighted in Yellow are considered "Hard to Read" (typically 20-29 words). Sentences in Red are "Very Hard" (30+ words). Breaking these long sentences into shorter ones usually improves your readability score.

The sentence segmentation logic works for most Latin-based languages, but the Readability Scoring (Flesch-Kincaid) and Syllable Counting are specifically tuned for English phonetics and vowel patterns.

For general web content and high readability, aim for an average of 15 to 20 words per sentence. Academic and technical writing often averages 20 to 25 words, but anything consistently above 30 words risks losing the reader.
