How to use the Text Line Counter
- Paste or type the text you want to measure.
- The counts update as you type - no button needed.
- Compare total lines with non-empty lines to see how much is blank.
- Check the longest line for anything that will wrap oddly.
About this tool
The Text Line Counter is built for speed and accuracy: every calculation runs in your browser, so your data never leaves your device and the result updates as you type. It works equally well on a phone, a tablet or a desktop, and it is free to use as many times as you like.
Common use cases
- Checking that a log file export is complete.
- Counting the lines in a poem or a lyric.
- Verifying a CSV row count before import.
- Measuring a config file against a size limit.
Tips for the best result
- Use the latest figures you have - even a small change in rate or term can shift the outcome by hundreds.
- For annual figures, divide by 12 to get a monthly number you can compare with the result.
- Bookmark this page and revisit the calculation as the inputs change.
Frequently asked questions
How are blank lines counted?
A line containing only whitespace (spaces, tabs) counts as blank. Any non-whitespace character makes the line non-empty.
Is there a size limit?
No. The tool counts whatever you paste, and because it runs locally there is no upload limit.
