English copy review
Readability Score Calculator
Estimate how demanding a draft may feel with Flesch Reading Ease, grade level, Gunning Fog, sentence length, complex-word examples, and reading time. Use the scores to find editing candidates without flattening expert content.
Paste at least a short paragraph for a more stable estimate. Headings and abbreviations can affect sentence detection, so read the highlighted examples beside the scores.

Readability Score Calculator
Calculate Flesch Reading Ease, grade level, Gunning Fog, and reading time.
Understand the scores
Use readability formulas to find friction, not to erase expertise
Flesch Reading Ease generally rises when sentences and words become shorter. Estimated grade level and Gunning Fog move in the opposite direction: higher values indicate more demanding copy. These are formula results, not assessments of accuracy, originality, or subject expertise.
A university policy guide may legitimately score as difficult. A sales page for busy school administrators may need a cleaner route through the same ideas. The useful question is whether the intended reader can follow the argument without rereading avoidably dense sentences.
- Reading Ease. Use the relative score to compare drafts, not as a pass-or-fail grade.
- Estimated grade level. Treat it as text complexity, not the education level of your audience.
- Gunning Fog. A second formula can reveal whether long sentences and complex words are driving difficulty.
- Long-sentence list. Edit the sentences that carry too many separate decisions or qualifications.
- Complex-word examples. Keep necessary terms and explain them; replace only needless complexity.
A practical workflow
Make the draft easier to use without making it simplistic
The score points to places worth reading again. The actual edit should preserve the claim, evidence, and professional tone.
Identify the reader and task
Decide whether the reader is comparing services, following instructions, reviewing research, or making a purchase. Clarity means something different in each situation.
Inspect the difficult passages
Start with highlighted long sentences. Separate independent ideas, make the subject clear, and move conditions close to the statement they qualify.
Run the comparison again
Recalculate after editing and compare both versions. Keep the revision only when it becomes clearer without losing important detail.
Worked example
Professional does not have to mean difficult
A campaign brief might say: “Following the preliminary assessment of prospective publishers, implementation will commence subsequent to client authorization.” The sentence is grammatical, but it makes a simple approval step feel remote.
A direct version says: “We review the publishers first. Work begins after you approve the shortlist.” The meaning is easier to scan, the sequence is clearer, and no important condition has been removed.
A useful editing pass
- Keep one main decision in each sentence.
- Prefer a concrete verb when a noun phrase hides the action.
- Explain specialist terms when readers need them.
- Use headings to separate stages or questions.
- Read the paragraph aloud before accepting the score.
Limits and judgment
The formulas estimate English text, not communication quality
Syllable counting and sentence detection are approximate. Product names, URLs, abbreviations, lists, and non-English wording can distort the result. Very short samples also move sharply when a single sentence changes.
A low Reading Ease score does not prove bad writing, just as a high score does not prove useful writing. Accuracy, evidence, organization, tone, accessibility, and the reader’s prior knowledge still need human review.
- Language. The formulas are intended for English copy and should not be transferred to other languages.
- Sample size. Use complete paragraphs rather than one headline or sentence.
- Specialist terms. Keep necessary terminology and add an explanation when appropriate.
- Privacy. The submitted text is processed for the result and is not stored as a draft.

Common questions
Readability questions editors ask most often
What is a good Flesch Reading Ease score?
The useful range depends on the reader and purpose. Compare your draft with successful material written for the same audience instead of using one universal target.
Does a high grade level mean the content is bad?
No. Technical, academic, legal, and professional topics may require demanding language. The score helps locate complexity; it does not judge whether that complexity is necessary.
Should I remove every complex word?
No. Replace needless jargon, but keep precise terms when they carry important meaning. A short explanation is often better than an inaccurate simple synonym.
Why do headings and abbreviations affect the result?
Readability formulas depend on detected words, sentences, and syllables. Fragments, initials, URLs, and unusual punctuation can change those counts.
Can the calculator detect AI-written or plagiarized text?
No. It measures surface features related to reading difficulty. It does not establish authorship, originality, factual accuracy, or editorial quality.
