Wiki Life: Readability Tools

readability_iconBlog posts that are concise and easy to read make for a better reading experience for the people looking at your articles. What makes an article easily readable and how do you gauge the readability of your writing? In this post, we will look at a few tools that can improve your posts.


English literacy statistics in the United States can vary but according to one study, “50% of adults cannot read a book written at an eighth grade level”. Another study shows the average college freshman reads at a seventh grade level.

Readability is generally assigned via a grade level to show the difficulty of the content. The most common metric is the Flesch-Kincaid Grade Level test which creates a numerical score showing the level of education someone needs to read the text.

Readability tests can assess your TechNet contributions to make sure it’s at the right level for your audience. For general writing, you probably want to target the Grade 7 or 8 level. This means writing shorter sentences without a lot of industry jargon or complex words. This writing is also known as Plain Language.


There are a few tools out there that can help you discover how clearly you are communicating. Sometimes the scores can differ between them so try a couple.

Microsoft Word & Outlook

You can use Word to view the readability score of your writing. You can get this information so it appears during every spell check. You can also turn it on within Outlook so you can make sure you are communicating clearly through email. To learn how to enable Office readability statistics, see Test your document's readability.

Once these settings are enabled, the following stats appear after a spell check.

There are also third-party websites you can use to discover readability indicators:

Both allow you to input free-form text or browse to an existing URL. also lets you upload files to the site via their premium plan.

When running a test, you get all the major readability scores (Flesch-Kincaid Grade Level, Flesch-Kincaid Reading Ease, Gunning Fog Index, etc.), links to help decipher what they mean, and basic text statistics. also provides insight into the text’s Tone, Sentiment, Gender, and Keyword Density.

If you want to make sure your Wiki posts are easy to read by everyone, measure the readability of your text before you post it. This can help people better understand your content and it may also help you become a better writer.

FYI: The above blog post achieved the following Flesch-Kincaid Grade Level ratings:

  • Microsoft Word: 9.4

    Wow, what a nice post! The layout and some simple picture to make it highly attractive! Good job!

    1. Thanks, Peter. Glad you enjoyed it.

  6. Excellent advice. I have been using a script I wrote in 2012 to measure readability of my Wiki articles, based on a 2006 blog post. It computes a score based on words per sentence and word size, but does not convert into a grade level. I will need to compare. These tools seem better, and based on recognized standards.

    1. Thanks, Richard. Sounds like your script was ahead of its time.

  7. These are some fantastic resources. Thanks, Ken!
