Frequently Asked Questions
How are lines counted?
Lines are split by newline characters. Every newline creates a new line, so a text ending with a newline has an extra empty line at the end.
Does my text get uploaded anywhere?
No. All counting happens in your browser. Your text never leaves your device.
What counts as a blank line?
A blank line is any line that is completely empty or contains only whitespace characters like spaces and tabs.
How is average line length calculated?
Average line length is the total character count of all lines divided by the number of lines, rounded to the nearest whole number.
Can I count lines in a code file?
Yes. Copy and paste your source code into the text box. The counter works with any pasted text including code, CSV data and log files.
