Readability Score
How TextScore measures whether your audience can actually read what you wrote.
Readability determines how easily a reader absorbs your text on first pass. It is not about dumbing things down. It is about removing friction between your idea and your reader's understanding. TextScore calculates this using the Flesch Reading Ease formula, then maps the result to a letter grade.
The Flesch Reading Ease Formula
The formula scores text on a scale of 0 to 100. Higher scores mean easier reading. It uses two inputs: average sentence length and average syllables per word.
Formula: 206.835 - (1.015 x average sentence length) - (84.6 x average syllables per word)
Score Ranges
- 90-100: 5th grade level. Very easy to read. Simple sentences with common words.
- 80-89: 6th grade level. Easy. Conversational English.
- 70-79: 7th grade level. Fairly easy. Standard for consumer content.
- 60-69: 8th-9th grade level. Plain English. Ideal for most online writing.
- 50-59: 10th-12th grade level. Fairly difficult. Longer sentences, harder words.
- 30-49: College level. Difficult. Academic or technical writing.
- 0-29: Graduate level. Very difficult. Legal documents, medical literature.
TextScore Thresholds
- Good (Green): Score of 60 or higher. Your text is accessible to most readers.
- Fair (Yellow): Score between 40 and 59. Some readers will struggle. Consider simplifying.
- Poor (Red): Score below 40. Most readers will bounce before finishing.
Target Scores by Platform
Different platforms reward different reading levels. Match your score to where you are posting.
X (Twitter)
Target: 70-90. Short, punchy sentences win here. You have 280 characters. Every word needs to earn its place. Avoid multi-clause sentences entirely. If your post has a comma, ask yourself if it should be two posts instead.
Medium
Target: 55-75. Medium readers expect more depth than a tweet but will still skim. Mix short and medium sentences. Break up paragraphs every 2-3 sentences. Use subheadings to let readers jump to what matters to them.
Discord
Target: 75-90. Discord messages are casual conversation. Write like you talk. One idea per message. Skip formal phrasing. If you would not say it out loud to a friend, rewrite it.
Target: 55-70. Professional but readable. Avoid jargon unless your audience shares it. The best-performing LinkedIn posts read at an 8th-9th grade level, not a graduate level.
Before and After Examples
Example 1: Business Writing
Before (Score: 28 - Poor)
"The implementation of the aforementioned strategic initiatives necessitates a paradigmatic shift in organizational methodology, whereby stakeholders must collaboratively synthesize their respective contributions toward the actualization of predetermined objectives."
After (Score: 72 - Good)
"These new strategies require a change in how we work. Teams need to work together and combine their efforts to hit the goals we set."
Example 2: Product Description
Before (Score: 35 - Poor)
"Our proprietary algorithmic framework facilitates the identification and subsequent remediation of textual deficiencies through multi-dimensional linguistic evaluation parameters."
After (Score: 68 - Good)
"Our tool finds problems in your writing and shows you how to fix them. It checks multiple angles: readability, tone, spam risk, and more."
How to Improve Your Score
Quick Fixes
- Split long sentences. If a sentence has more than 20 words, break it in two.
- Replace big words. "Use" beats "utilize." "Start" beats "commence." "Help" beats "facilitate."
- Cut filler phrases. "In order to" becomes "to." "Due to the fact that" becomes "because." "At this point in time" becomes "now."
- Remove prepositional chains. "The analysis of the performance of the system" becomes "the system's performance analysis."
- Read it out loud. If you run out of breath, your sentence is too long.
What Not to Do
Do not sacrifice accuracy for simplicity. If your topic requires technical terms, use them - but define them on first use. A readability score of 100 is not the goal. The goal is to be as clear as your subject allows.
