  • Readability Score

    Readability Score

    The first thing you can see in the readability score checker is obviously a readability score calculator. It uses several combined tests and their unique characteristic to say what exactly you can do with your text. Is it easy to read? What sort of audience can read it? Our readability score is based on Flesch Reading Ease, Flesh Kinkaid Grade Level, SMOG Index, Gunning Fog Score, and Automated Readability Index. It's totally okay if those words make no sense. But we will also touch upon major terms.

  • Text Difficulty Level

    Text Difficulty Level

    Our text complexity tool starts by determining overall text complexity. Some texts are specifically created for their target audience. If you are in college — the text must fit certain requirements. In high school, you can get away with laxer language. By seeing the level of difficulty you can ensure that your text is understood by your intended audience. In this situation, everyone wins!

  • Sentence Complexity

    Sentence Complexity

    Sentence complexity analyzer can tell you all about your sentences. How long are they? Do you have two complex sentences together? Should you put in shorter sentences? Can your audience read the text or there are some changes to be made? This is why you need a sentence readability checker. This tool considers the average length of sentences and the percentage of long sentences. This way you can find a perfect balance and make your text understandable for those who need to read it.

  • Percentage of long words There must be at least some balance between complex and easy language.
  • Average length of words No one wants to read a never-ending list of long words written in a row.

Flesch Kincaid Grade Level Checker

The Flesch-Kincaid readability tool is not far from the previous tool. They were actually invented simultaneously and use similar characteristics. Flesch Kincaid readability calculator also evaluates:

  • Word length
  • Sentence length

However, their value this time is slightly different. It also counts the total number of words and sentences. With precise mathematical calculations, it can tell you what people can read your text. Flesch Kincaid grade level online is easily accessed here. So there's no need to look anywhere else!

Gunning Fog Index

Our readability software can do so much more than we have already talked about. Gunning Fog index allows us to evaluate:

  • Number of words per sentence
  • Quantity of long words

It is much more simple than it sounds: short sentences with equally short words get higher scores because they are easier. "Fog" is added to the text if a person doesn't understand what they are waiting about. In other words: the simpler the better. So make sure you test your document's readability now to show how well you know your topic or have an expert "do my assignment". Avoid fog and achieve clarity!

Automated Readability Index 

Automatic readability checker asses written pieces quite similar to other tools using:

  • Word difficulty (number of letters per word)
  • Sentence difficulty (number of words per sentence)

So when you check readability online the test runs a couple of formulas. For example, if your index is 10 — the text is perfect for high school students. Depending on the index, the text will fit varied categories and ages. The same principle is applied for other similar techniques and formulas. We just combine them all together into one excellent test.

SMOG Index Readability Check

Our best automatic readability checker does not shy away from using the SMOG index. What would you ask? Well, it stands for Simple Measure of Gobbledygook. Did not help much, now did it? Let's put it in a different way.

When we are assessing readability, we also estimate the years of education the average person needs to understand any piece of writing. That's how this tool works:

  • The machine counts 10 sentences near the beginning, 10 in the middle, and 10 near the end
  • Analyzes every word with 3 or more syllables
  • Rounds it to the nearest 10
  • Adds three to this figure.

And voila! You know how to change your text or whether there is nothing to improve.

Readability Test Table

Now that you know how to use the readability test tool, it's a perfect time to analyze the score you might get. Here is a table for reference.

Readability is a characteristic of a text. It shows whether people can read one's text with ease. There are different levels of this characteristic depending on the intended target audience.
