This readability formula gives the score or grade level of your writing using average syllables per word and sentence length. The Flesch Kincaid readability test is one of the most popular tests out there.

2. Linsear Write Grade

The Linsear Write test is a little different from the ones on this list as it calculates a score based on a sample of the writing instead of analyzing the entire article.

The main principle behind this test is easily understood by many, essentially surrounding the general idea that the shorter a word or sentence is, the easier it is to read and understand.

4. Dale-Chall Readability Grade

The Dale-Chall readability test is a bit similar to the Spache test in the sense that it references an existing list of words to figure out how hard it is to read a piece of content. However, this list is a lot longer and sets a baseline for what words are considered general knowledge.

This test also factors in the average sentence length and adds it to the number obtained using the existing list of basic words that middle-school readers would know.

5. Coleman Liau Index

The Coleman Liau index is one of the few tests that rely on the average number of characters and relates them to the number of sentences. In contrast, most scales and tests use syllables which makes more sense as the more syllables a word has, the harder it is to read.
