Why is readability quintessential for any written work?

If your content is barely readable, it means you will fail to achieve the main purpose of writing it – attract your target audience. Thus, you should be focused on making your text readable, or, in other words, comprehensible.

There is one significant aspect to remember: the readability of your content should be correlated with the intellectual level of your audience. Note: a low readability score may not always refer to your text’s incomprehensibility.

Written works of higher academic levels, such as Master’s and PhD, often have low readability scores, which predominantly indicate sophisticated terminology.

However, if your audience consists of scholars, those “unfathomable terms” will be typically used in the field under investigation. So, basically, a well-written complex scholarly text is not technically unreadable, but the unprepared readers cannot understand it.

In any case, you should make your content totally readable for your target audience. Your text should grab attention, evoke interest, and instigate interaction between the ones knowledgeable in your sphere.

How to define a readability score?

If to look at a technical side of a readability score, it unravels a special computer-calculated index. This very index denotes an educational level required to comprehend a specific content without difficulty.

The readability checker made by PlagiarismSearch specialists employs well-proven readability formulas, which were previously tested by content-generating professionals.

Moreover, we have also come up with our unique scoring techniques that can deeply scrutinize any written content, from small essays to huge clusters of text on a multi-layered website.

Our readability checker will generate definitive suggestions to improve your content significantly. As the final score of your text’s readability directly depends on its academic or professional level, it makes each readability detection unique.

0-10 Readability Grade may be sufficient for dissertations and complex creative oeuvres, while the same score is not desirable for mass media articles or typical college research papers.

The determining factors for comprehensive readability scorings are:

  • Typical length of sentences
  • General number of syllables
  • Multi-syllable words percentage
  • Typical length of words
  • The equilibrium between familiar and unfamiliar words
  • The equilibrium between simple and complex sentences

The particularities of the Flesch reading ease test

The general readability of a text is determined by the Flesch reading ease test, which was specifically elaborated for this purpose. In order to measure the readability score of a given content effectively, two variables are applied:

the typical or average sentence length
statistically average number of syllables per every word

After the tool completes the analysis based on the Flesch reading ease test, it generates a score between 0 and 100. If your score is from 90% to 100%, it implies your content is extremely comprehensible, even for elementary school readers. In contrast, if your score is from 0% to 10%, it implies that your content is intricate, am biguous, or intended for a narrow audience of specialists highly competent in a particular sphere. There are also average scores, some of which are closer to the complex level of readability, and others are closer to the simple level of readability. Our table below elucidates all levels of Readability Score, which encompass Adult Reading Level, Comments, and Suggestions.

The fundamental algorithm of the test itself discerns lengthy sentences and words as difficult to read. Thus, even if your scientific text is satiated with complicated terms, your sentences should not be too extensive. If it is possible to shorten a certain sentence, dividing it into two or even more, so better opt for the optimal length. At least, it is difficult to comprehend a scholarly paper that consists only of long over structured [М1] sentences. Even academicians may find such lengthy complicated paragraphs difficult to read. Therefore, such a text will obtain the lowest score. Logically, a piece full of brief sentences with short words will get the highest score.

Flesch-Kincaid Grade Level

History of The Flesch Reading Ease Test

Rudolph Flesch, who worked for the Associated Press as a quality consultant, attempted to come up with a special technique to make each newspaper article more readable, in accordance with the demands of each target audience. This way, he invented The Flesch Reading Ease test in the 1940s. The readability test provided by Flesch appeared to be a ground-breaking invention. It greatly improved the quality not only of the Associated Press articles, but also influenced the creation of similar readability scores to check all the written texts possible. However, the initial formula was quite difficult to use by ordinary reporters and writers. Hence, when thirty years passed after the Flesch presented his idea, Peter Kincaid along with his Navy researchers’ team took up the formula and facilitated its implementation. From that moment on, the general name of this readability test became The Flesch-Kincaid Grade Level score.

Basic Framework of the Flesch-Kincaid Grade Level Score

The calculation of the Flesch-Kincaid Grade Level score interrelates the scanned test with a grade level equal to the one of the United States. However, unlike the Flesch-Kincaid score, which makes a score of 8.4 equal to the comprehension of an average 8th grade student, our readability tool discerns 61-70% as the typical score for students of this academic level.

Anyway, the Flesch-Kincaid formula is applied to versatile readability checkers despite their possible discrepant and uniquely programmed features.

Determining factors:

Average Word Length
Average Sentence Length

How to improve your writing level by using the Flesch reading ease score

If we think about a simple fact: a good writer is a good reader, then we can also easily assume that being a decent writer means knowing your audience well. Having evaluated the target readers of your potential text, you can start the actual writing process. This task is simpler if your content is suitable for a wide audience. For instance, every literate adult person can have a relatively equal comprehension of such topics as fashion, tourism, ecology, time management, business coaching, motherhood, gender diversity, etc. Still, you may also use some applicable complex terms from time to time, which will influence your general readability score. The most essential aspect to remember: a low readability score does not always indicate that your text was written ambiguously. However, if you do not produce a sophisticated scientific work, a low readability score may point to overcomplication in specific sentences. For instance, an ordinary article for a blog, which discloses an abundance of highfalutin sentences will look inappropriate. However, it would be strange to simplify idiosyncratic scholarly language only for the sake of getting a medium to high Readability score. Thus, only an individual case shows whether it is beneficial to get a lower score or to get a higher score.

Besides showing the exact score of your text’s legibility, the checker will provide you with valuable comments and recommendations, which are aimed at making your writing style more coherent and linguistically appropriate. It will surely help you to come up with the most favorable vocabulary and concise sentence structures.

The following two suggestions will make your Flesch reading ease score feedback more beneficial:

1. Make your sentences more succinct

Not everyone perceives the advice to shorten your sentences correctly. It does not mean that your text should be full of short sentences. However, if it is possible not to make your sentence too extensive, then it is better to divide it into two average-length sentences. Succinct sentences are more appealing to your readers. It helps your audience not to use all their energy and attention to interpret your complex and long-winded writing. Shorter sentences will definitely contribute to higher readability score.

2. Do not misuse complicated terms

Even when you produce a scholarly work, such as a dissertation, it should not be difficult for your readers’ perception. An experienced specialist will also sense the unnecessary exhaustion when reading a work full of terms and complicated elucidations. It is also generally stated that it is more complicated to comprehend words that contain more than four syllables. If it is possible to change one complex term for a simpler word, go for it! However, in certain cases, scientific terms cannot be interchangeable or do not have the appropriate synonyms. In contrast, when writing something informal, you are even allowed to use slang and jargon.
