Text Readability Report

“The ease with which a text can be read and understood varies depending on its unique qualities. One important factor that determines how easy it is to read your writing is how challenging it is.
A text readability analysis is available via the online book editor for Manuscripts. The way a text is presented, such as the font choice, white space, and context, determines how readable it is (the words and sentences on the page). The average sentence length, average number of sentences, average number of letters in a word, and many more metrics are included in this report’s readability metrics section. In order to improve their sentences’ readability on a professional level, the consumers of this report will be able to.”

Text Standard

The Text Standard measures the complexity and ease of understanding of a given piece of text. It considers things such as the length of words, sentence structure, grammar, and vocabulary. It is intended to evaluate the suitability of text for particular audiences. Generally, if the text is found to be fairly easy, it can be read by anyone understanding basic English. Text which is marked as difficult generally requires an audience with a higher level of English, such as native speakers. Confusing text has a complex structure and will usually require a more thorough understanding of the language. Below is the table having list of all the measures of Text Standard.

Grade Level

Text readability grade levels are standards that help measure the complexity of written texts and determine the readers’ capabilities in understanding them. The complexity is measured through various methods such as sentence length, word length, complexity of words used and the arrangement of ideas. The grade level assigned to a text is determined by the experience and reading skill of the individuals intended to read the text. It is important to ensure that texts have an appropriate readability grade level so that readers can easily understand the material. When creating texts, it is essential to use a variety of vocabulary appropriate to the readability of the intended audience. This helps improve readability, comprehension, and overall engagement with the text.


The Flesch-Kincaid Grade Level is a measure of the readability of written text that is used to determine the grade level of a text.

Sentence Count

A sentence count report can provide useful insights into a written document. It provides a count of the number of sentences in a given text and can be used to help identify any discrepancies in the overall length and format. It is often used when editing and proofreading written content, helping authors and editors ensure that each sentence flows smoothly and is of the appropriate length. A sentence count report can also help identify areas of redundancy, or sections that are propelling the text towards a more conversation-style layout. Sentence count may also be used to compare similar written documents. For instance, writers might use it to determine which of two different drafts has the most important content or to determine which is better structured and easier to read.

Word Count

The Word Count report offers a comprehensive summary of the total number of words found in a given document. It categorizes words according to various criteria such as total number, type, frequency, structure etc. The report provides a precise measure of the complexity of the document.

The information found in this report can be used to determine the length of a document, determine readability statistics, strengthen content optimization efforts, and troubleshoot formatting issues. Additionally, users can access a detailed breakdown of each individual word, including its frequency, type, and location in the text. Ultimately, the Word Count report provides an essential summary of text contents for any given document.

Average Sentence Length

Average sentence length is a concept in linguistics and grammar that measures the sum of all the words in a sentence divided by the number of sentences in a given text. It is used to determine the complexity of the text and can be a useful tool for both writers and readers alike. It is usually calculated in terms of words per sentence and some experts consider 20-25 words per sentence to be an average length. Short sentences can be used to make a point more quickly and clearly, whereas longer sentences can help provide a more complete explanation. Additionally, the average sentence length can help identify whether the text is easy to read and understand or not. It is also an important metric when creating marketing or educational materials, where clarity of writing is crucial.
