  2. Line statistics update in real time as you type

Frequently Asked Questions

What counts as a blank line?

A blank line is any line that is completely empty (zero characters) or contains only whitespace characters (spaces, tabs). Lines with content — even a single letter or digit — are counted as non-blank.

How is the average line length calculated?

Average line length is the total number of characters across all non-blank lines divided by the number of non-blank lines. Blank lines are excluded from the average to give a more meaningful metric.

Does it count the last line if it does not end with a newline?

Yes. The tool counts all lines regardless of whether the text ends with a newline character. A single line of text without a trailing newline is counted as 1 line.
