How is the Huerta Reading Ease score calculated?
The Huerta Reading Ease (HRE) scores are calculated using the formulas below. These formulas factor in two variables: the average number of syllables and of sentences per 100 words.
Huerta Reading Ease = 206.84 - (0.60 * P) - (1.02 * F)
P = Number of syllables per 100 words
F = Number of sentences per 100 words
The HRE requires the counts of the average number of syllables and sentences to be done in 100-word chunks of text. Additionally, the formula relies on sentence-ending punctuation to determine the number of words used in analysis and where to demarcate chunks of text. The HRE analysis reports the total number of words submitted but only analyze the words within sentences.
Using the words within sentences, the tool must create blocks of approximately 100 words. Of course, not all text is usually organized into neat groups of 100 words.
- When the text analyzed has more than 100 words, the tool groups the sentences as close to 100 words as possible. For multiple groups of 100, the number of syllables and sentences is calculated for each group of approximately 100 words and then averaged for use in the formula.
- When the text analyzed has less than 100 words, all the words are calculated. However, the formula assumes 100 words so your score may be less accurate.
Results
The Huerta RE score maps to a reading ease index of 0 to 100.
