What is a Readability Score?

Readability Scoring is the measurement of text to find out how easy it is to read. It looks at metrics like syllable count, sentence length and word difficulty to estimate the complexity of text. It then returns that in the form of a score.

What Do The Scores Mean?

Each measure is different, but the most commonly used are the Grade Levels. These represent the number of years of education someone will likely need to be able to read the text.

What Score Should I Aim For?

It depends on your audience, but if you are writing for the general public you should aim for a grade level of 6-8 (or below).

Which Algorithm Should I Use?

Each algorithm works well with different text or age groups, but if you do not already have one in mind we suggest you use the Flesch-Kincaid Grade Level. It is the most widely used, and reasonably accurate across a wide range of use cases.

Why Do My Documents Show Up As Grade 3? I Write Really Well!

A common misconception about readability scoring is that a higher score means "better" writing, but the reverse is actually true. Lower scores mean you are writing well, and there is a better chance your audience will understand your work.

    Readability Grade Levels

    A grade level (based on the USA education system) is equivalent to the number of years of education a person has had. A score of around 10-12 is roughly the reading level on completion of high school. Text to be read by the general public should aim for a grade level of around 8.

    Sentiment

    Sentiment analysis gives an idea of whether the text uses mostly positive language, negative language, or neutral language. For longer pieces, the text is split into three to give sentiment analysis for the beginning, middle and end of the piece.
