How to use the line counter
Check line structure instantly without changing the text you paste.
2. Read the line-specific metrics
Review total, non-empty, blank, unique, and duplicate lines together with the longest line and average line length.
3. Copy or download the summary
Copy the current result or download a text summary when you need the measurements for cleanup, QA, reporting, or another editing workflow.
What each line metric means
The counter separates row quantity, empty rows, repeated content, and line length so the result is easier to interpret.
Total, non-empty, and blank lines
Total Lines includes every row created by a line ending. Non-Empty Lines contains at least one non-whitespace character. Blank Lines includes empty rows and rows made only of spaces or tabs.
Unique and duplicate lines
Unique Lines counts distinct non-empty rows by exact text. Duplicate Lines counts repeated non-empty occurrences beyond the first copy, while blank rows are excluded from duplicate analysis.
Longest and average line length
Line length counts characters inside each row, not newline characters. Average Line Length includes blank rows as zero-length lines so it reflects the full pasted structure.
Useful line counting workflows
Line-level metrics help when rows represent records, tasks, log entries, or source lines.
Lists and copied spreadsheet rows
Check how many rows were pasted, spot blank separators, and estimate how much repeated content needs cleanup before sorting or deduplication.
Logs and terminal output
Measure log size by row count, identify blank lines introduced during copying, and compare repeated entries without opening a full editor.
Code and configuration snippets
Use total lines and line-length metrics for a quick structural check of source snippets, configuration blocks, or generated text.
Line Counter FAQ
How does this line counter count lines?
The counter recognizes Windows CRLF, Unix or Linux LF, and classic CR line endings. When text is not empty, each separated row counts as a line.
Do blank lines count as lines?
Yes. Blank rows count toward Total Lines. A row containing only spaces or tabs is treated as a blank line, while Non-Empty Lines counts rows that contain visible text or other non-whitespace characters.
Does a trailing line break create another line?
Yes. If the text ends with a line break, the empty row after that final break is counted as a blank line. This matches the visible row structure of the pasted text.
How are unique and duplicate lines counted?
Unique Lines counts distinct non-empty lines using their exact text after line endings are normalized. Duplicate Lines counts repeated non-empty occurrences beyond the first copy. Blank lines are excluded from these two metrics.
What do Longest Line and Average Line Length measure?
Line length is measured in characters without counting newline characters. Longest Line shows the largest row length, while Average Line Length averages character length across all counted lines, including blank lines as zero-length rows.
Does this line counter upload my text?
No. For normal use, the counting logic runs locally in your browser so the page can calculate results quickly without sending the pasted text to a TextBases server.
