How to count lines
- Paste your text into the input box. Total, non-empty, and blank line counts update as you type — no button press needed.
- Check the numbered view on the right to see each line with its line number. Blank lines are dimmed so they are easy to spot.
- Use the secondary stats — average and shortest line length — to check consistency in code, CSV files, or structured text.
- Copy your text at any time using the copy button at the top of the numbered view.
When you need to count lines
Code review and style guides
Many teams enforce maximum line length (80 or 120 characters). Check longest line to catch violations before committing.
CSV and data files
Verify a CSV has the expected number of rows, or spot extra blank lines that break parsers.
Log file analysis
Know exactly how many log entries are in a file before processing. Blank line count reveals formatting issues.
Poetry and song lyrics
Count lines per stanza, verify syllable spacing, or check that verses have the right structure.
Template validation
Ensure a text template has the expected number of lines before inserting it into a document or database field.
Copy pasting from PDFs
PDF-extracted text often comes with hard line breaks. Count lines to understand how broken the formatting is before cleaning.
Line counting in different contexts
A line in plain text is any sequence of characters terminated by a newline character (\n on Unix/macOS, \r\n on Windows). This tool handles both formats automatically.
Terminal commands like wc -l count the number of newline characters — so a file without a trailing newline will show one fewer line than expected. This tool counts the actual visible lines including the last one, regardless of whether it ends with a newline.
