Tips for Best Results
Vary sentence length
Mix short punchy sentences with longer descriptive ones. Monotonous length makes text dull. Aim for an average of 15 to 20 words per sentence.
Watch for run-on sentences
If your longest sentence exceeds 35 words, consider splitting it. Long sentences are harder to follow and often contain multiple ideas.
Balance sentence types
A healthy mix of declarative, interrogative, and exclamatory sentences keeps readers engaged. Too many of one type creates a flat tone.
Use questions strategically
Questions engage the reader and create a conversational tone. One question every 5 to 10 sentences is a good rhythm for blog content.
Check your paragraph structure
Each paragraph should contain 3 to 8 sentences focused on a single idea. Very long paragraphs are hard to scan on screens.
Read aloud to check flow
If you run out of breath reading a sentence, it is too long. Reading aloud is the simplest way to catch awkward sentence structure.
Use the sentence limit
Set a limit when writing abstracts, summaries, or any content with a sentence count requirement. The progress bar tracks your usage live.
Export stats for records
Click Export Stats to download a text file with all 11 statistics. Useful for tracking writing progress or sharing with an editor.
Abbreviations may affect the count
Periods in abbreviations like Dr. or U.S. may be counted as sentence endings. This is a known limitation of punctuation-based counting.
