Flesch-Kincaid Grade Level vs Reading Ease
Grade Level tells you the US school grade needed to understand the text (e.g., 8 = 8th grade). Reading Ease is a score from 0-100 where higher = easier. They measure the same thing differently — Grade Level 8 ≈ Reading Ease 60-70.

Reading Level vs Sentence Length
Reading level considers both sentence length AND word complexity (syllables). Our Sentence Counter measures length alone. Shorter sentences with simpler words yield easier reading levels.

Flesch-Kincaid vs SMOG Index
Flesch-Kincaid considers average sentence length and syllables per word. SMOG (Simple Measure of Gobbledygook) focuses specifically on polysyllabic words (3+ syllables). SMOG tends to give slightly higher grade levels for complex text.
