Tips to Improve Readability

  • Use shorter sentences: Break long sentences into smaller ones to improve clarity.
  • Choose simpler words: Opt for common, everyday words instead of complex alternatives.
  • Minimize jargon: Technical terms can be barriers to comprehension for non-specialists.
  • Use active voice: Active voice typically creates more readable, direct sentences.
  • Create shorter paragraphs: Shorter paragraphs are visually less intimidating and easier to digest.
  • Include subheadings: Break up long sections with descriptive subheadings to guide readers.
  • Add bullet points: Lists break complex information into scannable chunks.

Choose the Right Readability Level

Different content types and audiences require different readability levels:

  • General audience materials: Aim for grades 7-8 (Flesch-Kincaid).
  • Health and medical information: Grade 6-7 is recommended for patient materials.
  • Academic or professional documents: Grade 10-12 may be appropriate.
  • Children's content: Match to the intended age group and reading ability.
  • Technical documentation: May be higher, but clarity should remain a priority.

Using This Tool Effectively

To get the most accurate readability assessment:

  • Enter a substantial amount of text (at least several paragraphs) for more reliable scores
  • Analyze different sections of longer documents separately
  • Compare multiple versions of your text to see which performs better
  • Remember that readability scores are guidelines, not absolute rules
  • Consider your audience's expertise level when interpreting results
