How to Write for a Lower Reading Level

Your Flesch-Kincaid score came back at Grade 13. Your audience is general public. That gap is a problem — and the fix isn't to dumb things down. It's to be a better editor.

Writing at a lower reading level means removing friction. Shorter sentences. Simpler words. One idea at a time. None of that requires sacrificing accuracy, depth, or your voice. It just requires more drafts.

# Why It Matters

The average adult reads at roughly a Grade 7–8 level in everyday life — regardless of education. That's not a limitation of intelligence; it's how the brain processes text when it's not being forced to concentrate. Online readers in particular are scanning, distracted, and time-poor. They'll abandon text that requires too much effort before they'll slow down to decode it.

Plain, clear writing also converts better. Landing pages, product descriptions, and CTAs consistently outperform when written at Grade 6–8 vs Grade 12. Clarity is not just a courtesy — it's a commercial advantage.

# The Four Main Levers

## 1. Shorten your sentences

This is the single biggest driver of grade level. The Flesch-Kincaid formula weights sentence length heavily. Aim for an average of 15–18 words per sentence for general content. Mix short punchy sentences with medium ones. Rarely exceed 30 words in a single sentence.

## 2. Replace complex words with simple ones

Long words (three or more syllables) push the grade level up. Most of the time there's a simpler alternative that means the same thing. The swap doesn't weaken your writing — it strengthens it.

utilise	use

implement	put in place

terminate	end
insufficient	not enough

## 3. One idea per sentence

Complex sentences try to do too much. When a sentence contains multiple clauses connected by "which," "however," "although," or "whilst" — split it. Each clause usually deserves its own sentence. Readers shouldn't need to re-read to understand.

## 4. Cut unnecessary words

Many high-grade-level sentences are long not because the idea is complex, but because they're padded. "In order to" → "to". "At this point in time" → "now". "For the purpose of" → "for". Every word you remove is a word the reader doesn't have to process.

# What Not to Do

Don't break up sentences artificially. "The system failed. It failed because of a bug. The bug was in the authentication module." is lower grade level than one clear sentence — but it's worse writing. Short sentences should carry meaning, not just chop up existing ones.

Don't remove necessary technical terms. If you're writing for an audience who knows what "API" means, replacing it with "a thing that connects software" is more confusing, not less. Clarity means right for your reader — not just simple in the abstract.

Don't optimise the score, optimise the writing. You can game Flesch-Kincaid with short sentences that make no logical sense. The goal is comprehension, not a number.

# Target Grade Levels by Content Type

Grade 6–8 for general blog posts, marketing copy, and landing pages. Grade 8–10 for quality journalism and in-depth articles. Grade 10–13 for technical documentation aimed at specialists. Anything above 13 for a general audience is a signal to edit more.

# The Edit, Not the Draft

Almost no one writes at a low grade level on the first pass. The first draft is where you get the ideas out. Simplification happens in the edit — which is where the real writing actually takes place. Check your grade level after your first edit, not during the draft. Trying to simplify while writing slows everything down and usually makes both the speed and the quality worse.
