Line Counter — Free Online Tool
What is Line Counter?
The Line Counter calculates the exact number of physical or hard-coded lines in your text. Unlike paragraph counting, line counting is particularly crucial for programmers, data analysts, and sysadmins.
When dealing with source code, CSV data files, or server logs, the 'Lines of Code' (LOC) or total line count indicates the size and complexity of a file. This tool instantly parses your input and counts the total number of line breaks, providing an accurate metric for data files or code snippets.
When to use Line Counter?
Use the Line Counter when you are working with data files, logs, or source code. Developers use it to check the length of a script or to verify how many records are in a pasted block from a CSV file (since one line usually equals one record).
Sysadmins use it to count error lines in a chunk of server logs. If you need to manipulate these lines further, you can use our Sort Lines Alphabetically tool or the Remove Duplicate Lines tool to clean your data.
How to use this tool
- 1Paste your text or code
- 2Click 'Analyze' to count lines
- 3View total, blank, and non-blank line counts
The tool counts the number of physical line breaks (hard returns). It does not count 'soft wraps' caused by a small screen or browser window size.
Examples
| Input | Output |
|---|---|
| (10-line code snippet with 2 blank lines) | Total: 10 | Blank: 2 | Non-blank: 8 |
| (CSV file with 100 rows) | Total: 100 lines |
| (Log file) | Total lines counted for log analysis |
| Line 1 Line 3 | Total: 3 | Blank: 1 | Non-blank: 2 |
| (Empty file) | Total: 1 | Blank: 1 | Non-blank: 0 |
Rules & Behavior
- The count is based exclusively on hard line breaks (newline characters like or within the text string).
- Soft wrapping—where a long line wraps to the next line visually because the screen is narrow—does not increase the line count.
- Blank or empty lines created by hitting the Enter key multiple times are included in the total line count.

Frequently Asked Questions
What is the difference between line count and paragraph count?
A Paragraph Counter looks for blocks of text and ignores excess empty space. A Line Counter counts every single hard return (Enter key press), including completely blank lines. In programming and data analysis, every line—even an empty one—counts towards the structure of the file.
Does the tool count soft wraps?
No. If you write a very long sentence that visually wraps onto three lines on your small smartphone screen, the tool still counts it as 1 line. The line count only increments when a hard return (a manual line break) is present in the text.
Is this useful for writing essays?
Usually not. For essays and prose, you should use the Word Counter or Sentence Counter. Line counting is primarily a technical metric used by developers to measure source code (Lines of Code) or by analysts to count the number of rows/records in a CSV dataset.
Will it count blank lines?
Yes. By default, every newline character is counted, meaning blank lines are included in the total. If you want to clean up your text or code snippet before counting, you can use our Remove Empty Lines tool first.
Is the line count secure for source code?
Yes. All counting calculations are executed directly inside your browser. If you paste proprietary source code or confidential log files into the tool, the data never leaves your computer and is never sent over the internet.
