What is Flesch Kincaid Readability?

The Flesch Kincaid Readability is a test designed to assess the readability level of English text. It provides a score based on the average number of syllables per word and words per sentence, indicating the level of education a reader would need to understand the text on first reading. A lower score indicates the text is easier to read, while a higher score suggests it is more complex. This test is commonly used in the fields of education and publishing.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ FKRS = 0.39 \left( \frac{200}{10} \right) + 11.8 \left( \frac{300}{200} \right) - 15.59 \]

\[ FKRS = 0.39 \times 20 + 11.8 \times 1.5 - 15.59 = 7.8 + 17.7 - 15.59 = 9.91 \]

The Flesch Kincaid Readability Score is 9.91.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ FKRS = 0.39 \left( \frac{500}{25} \right) + 11.8 \left( \frac{750}{500} \right) - 15.59 \]

\[ FKRS = 0.39 \times 20 + 11.8 \times 1.5 - 15.59 = 7.8 + 17.7 - 15.59 = 9.91 \]

The Flesch Kincaid Readability Score is 9.91.
