Fry Readability Formula:
| From: | To: |
The Fry Readability Formula is a graph-based method for estimating the reading grade level of English text. It uses the average number of syllables and sentences per 100-word sample to determine text difficulty.
The calculator uses the Fry readability formula:
Where:
Explanation: The formula plots these two variables on a graph to determine the approximate reading grade level of the text.
Details: Readability assessment helps ensure that written materials are appropriate for the target audience, improving comprehension and engagement across educational, healthcare, and publishing contexts.
Tips: Enter the average number of syllables per 100 words and average number of sentences per 100 words. Both values must be positive numbers.
Q1: How accurate is the Fry Readability Formula?
A: The Fry formula is considered one of the more accurate readability formulas, particularly for longer texts, with a correlation of about 0.80-0.90 with actual reading difficulty.
Q2: What types of texts is Fry best suited for?
A: Fry works well with general reading materials, textbooks, and informational texts from elementary through college levels.
Q3: How does Fry compare to other readability formulas?
A: Fry is often preferred over formulas like Flesch-Kincaid for educational materials as it was specifically developed for school texts and uses a graph-based approach.
Q4: What are the limitations of the Fry formula?
A: It may be less accurate for very short texts, poetry, or technical writing with specialized vocabulary. It also doesn't account for conceptual difficulty.
Q5: How many word samples should I use for accurate results?
A: For best results, use three 100-word samples from the beginning, middle, and end of a text and average the results.
