What this tool does

Find lines that are too long for terminal output, code comments, email text, documentation, or plain text layouts.

This tool measures each line, compares it with your selected width, and reports overflow details.

Line width = character count or estimated visible width. Over-limit lines are flagged when width exceeds the max setting.

Example

Paste multiline text, select 80/100/120 or custom width, then review the line report.

Use cases

  • Terminal output QA
  • README formatting
  • Email plain text wrapping
  • Code comment style checks

Tips for better output

  • Use 80 columns for terminal-friendly text.
  • Use 100 or 120 for modern code review limits.
  • Check visible width for CJK-heavy text.
