Readability Score

For a general blog audience, aim for Flesch Reading Ease 60–70 and a Flesch-Kincaid grade of 7–9. Technical writing can run higher; fiction often runs lower.

Each word is scanned for vowel groups (consecutive vowels count once), with silent-e adjustment and a minimum of one syllable per word. It is an estimate — handy but not dictionary-perfect.

Each formula weighs syllables, sentence length, and "hard words" differently. Flesch-Kincaid rewards short sentences; Gunning Fog penalises long words; SMOG focuses on polysyllabic density. Use them together, not alone.

No — these formulas are purely structural. They will happily give a children's-book grade to gibberish if the sentences are short and the words are simple. Readability is a signal, not a verdict.
