Normalize input before counting: Trim trailing whitespace, collapse multiple blank lines into one, convert different line ending styles (CRLF, LF) to consistent format. This ensures accurate counts regardless of source formatting.
Consider context when setting thresholds: A paragraph might be 1-2 sentences in web content but 5-10 in academic writing. Provide guidance based on content type rather than universal rules that don't fit all use cases.
Combine paragraph count with other metrics: Average paragraph length, sentence variety, and readability scores provide complete picture of text structure. Paragraph count alone doesn't indicate quality—distribution and balance matter more.
Provide breakdown statistics: Show not just total paragraphs but also shortest, longest, and average paragraph length. This granular data helps writers identify problem areas—excessively long paragraphs that need splitting or choppy sections needing consolidation.
