How Readability Scoring Works

The Flesch Reading Ease formula measures two things: average sentence length and average syllable count per word. Longer sentences and bigger words lower your score. Shorter sentences and simpler words raise it.

The scale runs from 0 to 100. Higher is easier to read. Here's what the numbers mean:

• 70-100: Easy to read. Conversational. Good for social media and casual content.
• 60-69: Standard. Suitable for most blog posts and articles.
• 50-59: Fairly difficult. Acceptable for B2B content and industry publications.
• 30-49: Difficult. Academic or technical writing territory.
• 0-29: Very difficult. Most readers will give up.

Shorten Your Sentences

This is the fastest way to improve your score. Most readability problems come from sentences that try to do too much.

Before

"The marketing team, which had been working on the campaign for several months, decided to postpone the launch date because the analytics data suggested that the target audience was not yet sufficiently engaged with the preliminary content that had been published on social media platforms."

Readability score: 18

After

"The marketing team had worked on the campaign for months. They postponed the launch. Their analytics showed the target audience wasn't engaging with the early social media content."

Readability score: 62

Same information. Three sentences instead of one. The score jumped 44 points.

Choose Simpler Words

Big words don't make you sound smart. They make your reader work harder. Swap multi-syllable words for shorter ones when the meaning is the same.

• "Utilize" becomes "use"
• "Demonstrate" becomes "show"
• "Approximately" becomes "about"
• "Consequently" becomes "so"
• "Implement" becomes "start" or "do"
• "Facilitate" becomes "help"
• "Methodology" becomes "method"
• "Communicate" becomes "tell" or "say"

You don't have to eliminate every long word. Just replace the ones that have shorter alternatives with no loss of meaning.

Use Active Voice

Passive voice adds words and hides the actor. Active voice is shorter and more direct.

Before (Passive)

"The decision was made by the board to discontinue the product line that had been underperforming for the past two quarters."

After (Active)

"The board cut the product line after two quarters of poor sales."

Active voice doesn't just improve readability scores. It makes your writing more engaging. Readers connect with actors doing things, not things being done by unnamed actors.

Add Concrete Examples

Abstract language is harder to read than specific, concrete language. Compare:

Abstract

"Organizations should consider implementing strategies that address the multifaceted challenges associated with digital content distribution."

Concrete

"If your blog posts aren't getting traffic, check your readability score. Posts scoring below 50 lose half their potential readers."

The concrete version is easier to read and more useful. Specifics anchor your reader. Abstractions make them drift.

Different platforms reward different readability levels. Here are the targets you should aim for:

• X (Twitter): 70+. You have limited characters. Every word must be instantly clear.
• Facebook: 65+. Native posts should feel casual and easy to scan in a feed.
• Medium: 55-65. Readers expect substance, but not academic density.
• LinkedIn: 50-60. Professional but accessible. Avoid jargon even when writing for specialists.
• Blog posts: 55-70. Depends on your audience, but most successful blogs stay in this range.
• Email newsletters: 60-70. People skim emails. Make it easy for them.
• Landing pages: 55-65. Clear enough to convert, detailed enough to convince.

Don't Oversimplify

Readability isn't about writing at a third-grade level. A score of 100 isn't better than 65 if your audience expects depth. The goal is matching your readability to your audience and platform, not maximizing the number.

Don't Sacrifice Accuracy

If a technical term is the right word, use it. Don't say "the thing that keeps the engine cool" when "radiator" is what you mean. Readability improvements should come from sentence structure and unnecessary complexity, not from removing precision.

Don't Ignore Context

A medical journal article will have a lower readability score than a tweet. That's fine. The question isn't "what's my score?" It's "is my score right for where this will be published?"

Use TextScore to check your score against the right benchmark. A score of 45 is great for a white paper and terrible for a Facebook post.
