Does this ring a bell? You are reading something, perhaps a new article or a particularly lengthy email. Then, you suddenly realize that you’ve repeatedly been reading the same sentence. You understand the meaning of each word, yet you cannot seem to internalize the information. 

Readers may become stuck in a particular sentence for a variety of reasons, but frequently the issue is that the sentence is too long and complex. In other words, it is difficult to read.

This type of issue can be difficult to identify. A sentence or words can be grammatically correct but difficult to comprehend. Here, readability scores come into play.

What Is a Writing Level Detector?

The writing level detector is a type of readability indicator that predicts how difficult each sentence is to read among a crowd of sentence-length texts. 

Writing level detectors take a piece of your writing and assess the number of sentences, words, syllables, and characters in it. These formulas below will tell you the reading level and grade level of your text and help you figure out if your audience will be able to read what you’ve written.

Writing Level Detector: Tools for Determining Your Writing Level

If you are writing for children, teens, or adults, you will want a writing level that matches your intended audience. Educational publishing journals, novel and short story publishers, textbook publishers, and writers publishing with children and teens typically use a 6-8 grade level. 

A 7-9 grade level is often a good fit if you’re writing for high school or college. So how do you find your writing level?

These free readability formula analysis tools below will assess your content or grammar, and generate findings based on their calculations. The tools will also assist you in determining the reading level of your material and words used.

Generally, a 5th grader can assimilate texts with scores between 90 and 100. With a score of 60–70, 8th and 9th graders can decode the documents. With a score of 0–30, college graduates can digest the documents.

4. The SMOG Index

The Coleman-Liau Index uses characters instead of syllables to measure the length of each word and sentence. With this formula, you can get a grade. For example, 10.6 means that your text is right for a high school student in the 10th or 11th grade.

6. The Automated Readability Index

The Automated Readability Index gives you a number about the same as the grade level you need to digest the text. For example, if the ARI outputs the number 3, it means that third-grade students (ages 8–9) should be able to comprehend the text.

7. The Linsear Write Formula

 The Linsear Write Formula is a readability formula for English text. It was first made for the US Air Force to help them figure out how easy their technical manuals were to comprehend. 

Linsear Write Formula is made to determine the US grade level of a piece of writing based on the length of the sentences and the number of words with three or more syllables.
