Famous Text Readability Benchmarks

Readability scores in isolation don't mean much. A grade-12 result feels "hard" until you discover the US Constitution scores grade 17 and a typical software EULA scores grade 20+. Below: a calibration table of famous texts and everyday writing, scored across all six formulas using the same engine that powers the calculator.

How to read this table

The Consensus column is the mean of all six grade-equivalent scores — Flesch Reading Ease is converted to a grade scale first so it fits the same axis. Lower is easier. The Level band uses standard education categories:

• Elementary — grade 5 or below (children's books, plain-language guidelines)
• Middle school — grade 6 to 8 (general newspapers, popular fiction)
• High school — grade 9 to 12 (most magazines, professional writing)
• College — grade 13 to 16 (academic prose, government documents)
• Graduate / specialist — grade 17+ (legal contracts, regulatory filings, classical literature)

What this tells you about your own writing

A few patterns jump out once you have a calibration set in front of you:

• Lincoln still beats everyone. The Gettysburg Address — arguably the most famous American speech ever written — scores around grade 8. Short sentences. Common words. Two centuries later, it still works.
• Legal language is its own genre. EULAs, terms of service, and tax code routinely clear grade 20. Not because the ideas are complex, but because the sentence structures are.
• Children's books are not trivially easy to write. A well-crafted children's text scores grade 2 or 3 — but it conveys real narrative. Bringing your own writing to grade 8 is achievable; getting to grade 4 takes effort.
• "Easy reading is damn hard writing." — Nathaniel Hawthorne. The famous texts that score easiest are usually the ones whose authors revised the hardest.

Methodology

All texts are excerpts (typically 80–250 words) of public-domain sources or original constructed examples. Scoring uses the same in-browser engine documented on the formulas page — Flesch Reading Ease, Flesch–Kincaid Grade Level, Gunning Fog, SMOG, Coleman–Liau, and Automated Readability Index. No third-party APIs, no smoothing. If you score the same excerpt elsewhere you'll see the same numbers, modulo small differences in how each calculator splits sentences and counts syllables.
