With the constantly shrinking attention span globally, retaining an audience or readers on a post, webpage, or piece of writing is becoming more and more difficult. To ease this difficulty, it is essential to prioritize optimal readability when writing.

Readability is a major factor in determining whether a reader will read or skip your text. It shows how easy and understandable your text is.

An automatic readability checker, as its name suggests, is simply an online tool designed to check the readability score of a text.

What are the various Readability scoring formulas in the content?

Readability scoring formulas are invaluable tools. They tell who can read what, from students to web visitors, customers, and professionals. These scoring formulas provide insight into the reading grade, age, and overall comprehension level required to understand a text.

Our readability score checker tool applies the following formulas to check text readability and give real-time reports:

  • Flesch Reading EaseScore

    • This formula rates text by analyzing the average sentence length and syllables per word, assigning a score between 0 and 100. A higher score signifies easier readability.
  • Flesch Kincaid Grade Score

    • Shows the level of education a reader must have to understand a text.
  • Coleman Liau Index Score

    • considers characters rather than syllables per word and sentence length.
  • Automated Readability Index Score

    • Outputs a number approximating the grade level needed to understand a text.
  • Dale Chall Readability Score

    • This formula incorporates sentence length and the percentage of unfamiliar words not found in a set list of more than 3,000 commonly used words.
  • Linsear Write Formula

    • Specifically designed to calculate the grade level of a text sample based on sentence length and the number of words with three or more syllables in the text.
  • Gunning Fog

    • This evaluates syllable count and sentence length to determine a grade level, usually ranging from 0 to 20.
