What are Different Readability Formulas?
Readability formulas determine how difficult your text is by analyzing a sample of it. These formulas measure an average word length, how many syllables there are and an average sentence length to determine how easy your text is.
These formulas provide a useful readability level indicator. By looking at this indicator, you can determine whether your text is readable or not. It also determines this text’s grade level, so you can make sure that it is appropriate for your audience. For example, you can look will enable your readers to stay more focused on your topic.
There are different readability formulas that people can use for determining how understandable your text is:
1. Flesch Reading Ease:
This reading level calculator was invented to determine how difficult a certain text is. By analyzing text, you will have a score between 1 and 100, and there is a table that will enable you to interpret the value.
This test was first invented to help educators choose levels that are adequate for students’ academic level. But later on, it became widely used in other sectors. A text that scores 70% to 80% is appropriate for year 7 students. A professional text that is intended for marketing purposes, for example, shouldn’t score less than that. A text that scores less is more difficult to understand.
The formula is: 206.835 – 1.015 (total words/total sentences) – 84.6 (total syllables/ total words)
This is another readability level score used for deciding on the level of education required to understand a certain piece of writing. It is first invented by the US Navy for evaluating the complexity level of technical texts. Today, educators, parents, librarians, and students use it for educational purposes.
The formula is: 0.39 (total words/total sentences) +11.8 (total syllables/ total words) + 15.59
There is no upper bound for this score as it corresponds to the actual number of years of education needed for understanding a certain essay or paper.
3. Gunning Fog Index:
This readability system is based on the number of years of formal education needed to understand a certain essay. The test depends on comparing syllables and sentences.
The formula is: 0.4 [(words/sentences) +100 (complex words/words)]
Some of the complex words are not that difficult to understand but would still affect the readability level of your text. A text that scores 5 is very readable, while one that scores 20 seems rather difficult.
4. SMOG Readability:
This is another indicator that uses a reading level calculator to determine how difficult a certain text is. It was typically used for checking health messages but can be used to determine how readable it is if comparing with other types of writing.
For calculating using this formula you need:
- Count a total of 30 sentences.
- Then you should look through the group of sentences and evaluate how many words with three or more syllables, even if the words repeat.
- When you have calculated all the words needed, provide a conversion table to calculate the grade. A 7.4 score means that the essay is appropriate for a 7th or 8th-grade student.
5. The FRY Readability:
This is a graph-based test that is used for testing academic materials from elementary level to college level. The test depends on the fact that as we grow older, our vocabulary continues to grow.
Your steps for calculating using this formula:
- Choose 3 samples of 100-word passages randomly.
- Count the number of sentences and estimate the fraction of the last sentence to the nearest 1/10th.
- Count the number of syllables and make a table of the number of sentences and syllables for the 3 different samples.
- Now you have average sentence length and the number of syllables. Draw a dot where the 2 lines meet to find the area in the graph which corresponds to the readability level.
6. Coleman-Liau Index:
Just like other readability formulas, this one is used to help readers determine how easy it is to comprehend a certain piece of writing. However, this readability index is a bit different from others as it depends on characters rather than syllables to assess and evaluate a certain text.
The readability formula is calculated this way: CLI = 0.0588L- 0.296S- 15.8
Where L is an average number of letters per 100 words and S is the average number of sentences per 100 words. A 10.6-grade text is appropriate for a 10th grader while a 14.5 grade is appropriate for an undergraduate.
7. Dale–Chall Readability Formula:
This test relies on a table that is made up of 3000 words. These words are considered readable by any fourth-grade student. Any word that doesn’t exist in this table is considered rather difficult. The number of difficult words is then entered in a readability formula to find a score.
This is the formula: 0.1579 (difficult words/words x100) + 0.0496 (words/ sentences)
A high score means that this text is difficult to read.
