Frequently Asked Questions

What is the Flesch-Kincaid Reading Ease score?

The Flesch Reading Ease formula rates text on a 0-100 scale. Higher scores mean easier text. It considers average sentence length and average syllables per word. Most web content should aim for 60-70.

What grade level should I write at?

For general web content, aim for a 7th-8th grade level (Flesch score 60-70). This makes your writing accessible to the broadest audience. Academic and technical writing naturally scores lower.

How can I improve readability?

Use shorter sentences (under 20 words on average). Choose simple words over complex ones. Break up long paragraphs. Use active voice instead of passive. Avoid jargon when possible.

Why are long sentences highlighted?

Sentences over 25 words are harder to follow. Highlighting them helps you identify where to split or simplify. Aim for a mix of short and medium sentences for the best readability.
