The Flesch Reading Ease score is a widely-used readability test developed by Rudolf Flesch in 1948. It scores text on a scale from 0 to 100, where higher scores indicate text that is easier to read. The formula considers two factors: average sentence length and average number of syllables per word.
A score of 60–70 is considered plain English suitable for 13–15 year olds. Most business writing, blogs and web content aims for a score between 60 and 80.
It depends on your audience. For general web content and blogs, aim for a Flesch score of 60–70 (Standard to Fairly Easy). For technical documentation or academic writing, a lower score (40–60) may be appropriate. For consumer-facing content like landing pages, aim for 70–80.
Most successful blog posts are written at a Grade 6–8 level. This does not mean writing for children — it means writing clearly and concisely. Studies show that even highly educated readers prefer content written at a lower grade level because it is faster to read and easier to understand.
