The Flesch Reading Ease Scale is an internationally recognised test. It uses a simple formula to measure a document’s readability and gives it a score of between 0 and 100. A high score indicates that the text is easy to read.
For example, Time magazine is in the 50s and the Harvard Law Review is in the 30s. In some US states, all customer materials from insurance companies must have a Flesch score of 45 or over.
Rudolf Flesch, who created the system, warned: ‘Some readers, I am afraid, will expect a magic formula for good writing and will be disappointed with my simple yardstick. Others, with a passion for accuracy, will wallow in the little rules and computations but lose sight of the principles of plain English.
‘What I hope for are readers who won’t take the formula too seriously and won’t expect from it more than a rough estimate.’
The system calculates the average sentence length and the average number of syllables per word. This means that a lot of long sentences or long words will reduce your score. However, there are many longer words we use every day that won’t provide readers with problems (e.g. calendar, entertainment, effectively and maintenance).
|Flesch score||Readability level|
|90-100||Very easy (easily understood by an average 11-year-old)|
|60-69||Standard (easily understood by 13- to 15-year-olds)|
|0-29||Very difficult (suitable for university graduates)|
