How Flesch-Kincaid Grade Level Works
The formula estimates grade level from average sentence length and average syllables per word. Readscope translates that score into creator-friendly labels and platform checks.
Best use
Use this calculator to compare drafts and simplify text. A regex syllable counter is an estimate, so small differences from dictionary-based tools are normal.
