Free Dale-Chall Readability Formula with Word List - Original and Revised versions
Use our free Dale-Chall Readability Calculator to get the grade level of your text and determine if readers will be able to read and understand what you have written. Our Dale-Chall Formula uses its own graded wordlist to determine potential difficult words. Dale-Chall Formula compares its wordlist with your text and then calculates a U.S. grade level based on the number of difficult words with average sentence length. This formula is designed to assess materials above fourth grade levels.
( NOTE: Use our free Spache Readability Tool to calculate texts below fourth grade.)
Paste in a sample of text, between 200 and 600 words. To use the Dale-Chall Formula correctly, you should already have written your text for readers above third grade. Using its wordlist of familiar words (aimed at young ages), the Dale-Chall Formula will let you know if your text is too difficult to read within this age group.
(NOTE: You may also use our free readability tests tool to score standard and advanced texts).
