Reading Level
Enter some text to estimate its reading level.
Being told a piece of writing scores 65 on some named readability formula means very little without already knowing what that scale represents, but being told the same text reads at roughly an eighth-grade level translates immediately into something familiar, a school grade nearly everyone already has an intuitive sense of, no formula name or numeric scale required. This tool estimates the US school grade level a piece of text is actually written at, translating a passage's difficulty into a familiar grade rather than a named formula's raw score.
