Line Counter

A line counter counts the total number of lines in your text, including empty lines. It may also show: non-empty lines (lines with content), blank lines (empty or whitespace-only), the longest and shortest lines, and average line length in characters.

Lines are separated by line breaks (Enter key). Different systems use different line endings: Windows uses CRLF (\r\n), Unix/Mac uses LF (\n), old Mac used CR (\r). Good line counters handle all formats correctly and consistently.

Common uses include: checking code file length, verifying log file sizes, counting CSV/data rows, checking text document length, analyzing configuration files, billing for translation work, and meeting line limit requirements for submissions.

Yes, most line counters include the last line even if it does not end with a newline character. A file with "Hello\nWorld" has 2 lines, and so does "Hello\nWorld\n". Some tools have options to change this behavior.
