Line Counter
Count total, non-empty, blank and whitespace-only lines, detect the line-ending style, and see the longest and average line length.
wc -l and every editor gutter. An empty line (zero characters) is counted separately from a whitespace-only line (spaces or tabs only) because they behave differently in code, YAML and diffs. Your text is never modified: line endings are normalised for analysis only.How it works
- Type or paste your text into the text area.
- Line statistics update automatically as you type.
- Copy a plain-text summary of the results.
Frequently Asked Questions
Why does my count differ from my editor?
Usually because of the trailing newline. This tool treats a final newline as a TERMINATOR, not a separator, so "a\nb\n" is two lines — which matches wc -l and every editor gutter. A tool that reports three is counting the empty string after the last newline.
What is the difference between an empty and a whitespace-only line?
An empty line has zero characters. A whitespace-only line contains spaces or tabs but nothing visible. They are counted separately because they behave differently in code, in YAML and in diffs — collapsing them is why many "non-empty line" counts are wrong.
Does it change my text?
No. Line endings are normalised for ANALYSIS only; the text you pasted is never modified and nothing is written back.
What does "mixed" line endings mean?
The text contains more than one style — for example some lines end with CRLF and others with LF. That usually indicates a file edited on both Windows and Unix, and it is worth knowing because it produces spurious diff noise.
