Line Counter for Instant Line Statistics
This line counter counts and categorizes every line in your text the moment you type or paste it. Paste code, a data file, or a plain document and you immediately see the total line count, how many lines hold content, and how many are empty.
Beyond a raw count, it breaks lines into non-empty, blank, and whitespace-only, measures your longest, shortest, and average line length, and detects the line ending your file uses. It's handy for developers checking code length, writers reviewing document structure, data analysts verifying row counts, and students meeting line requirements.
How to Use the Line Counter
Enter your text
Type directly in the Input Text area or paste content with Ctrl+V (Cmd+V on Mac). The line numbers panel on the left updates as you go.
Read the main stats
See Total Lines, Non-Empty, and Empty counts right away, with a progress bar showing the percentage of lines that contain content.
Check extended details
Below the main stats, review Blank, Whitespace-Only, Longest, Shortest, and Average line length, plus the detected Line Ending.
Copy or clear
Click Copy Stats to copy all statistics to your clipboard as plain text, or Clear to reset the text and counts (a confirmation appears first).
Features
Real-Time Line Counting
Statistics update instantly as you type or paste, with no button to press and no processing delay.
Line Number Display
A monospace line-number panel scrolls in sync with your text and highlights the line your cursor is on.
Empty Line Analysis
Separates fully blank lines from whitespace-only lines so you can spot invisible spaces and tabs.
Line Length Statistics
Shows the longest, shortest, and average character length across your non-empty lines.
Line Ending Detection
Detects LF (Unix), CRLF (Windows), CR (classic Mac), or Mixed when multiple types appear.
Content Percentage Visualization
A progress bar shows what share of your lines hold content versus empty space at a glance.
One-Click Copy
Export every statistic as formatted plain text with the Copy Stats button for docs or records.
Who Uses a Line Counter?
Developers
Count lines of code, check file length, and clean up stray blank or whitespace-only lines.
Writers & Editors
Analyze line and paragraph distribution and meet line-based formatting requirements.
Data Analysts
Verify CSV or log row counts and confirm a file has the expected number of records.
Sysadmins & Students
Check configuration file lengths or hit a required line count for an assignment.
Frequently Asked Questions
How do I count the number of lines in text?
Type or paste your text into the input area. The Total Lines count appears instantly, along with the number of non-empty and empty lines. There is nothing to click or submit.
Does it count empty and blank lines?
Yes. Empty lines are counted separately from content lines, and the extended stats split them further into Blank lines (zero characters) and Whitespace-Only lines (containing only spaces or tabs).
Can I count only the non-empty lines?
Yes. The Non-Empty stat shows how many lines contain at least one visible character. A line with only spaces or tabs is treated as empty, not as content.
How is a "line" defined? Does word wrap count?
A line is defined by line-break characters, not by how the text wraps on screen. The tool splits on LF, CRLF, and CR, so visual word wrapping inside a long line does not add to the count.
Why does line ending type matter?
Operating systems mark line ends differently. When files move between systems, mismatched endings can add stray blank lines, break scripts, make Git show every line as changed, or collapse text into one long line. "Mixed" means more than one ending type is present, which is usually worth fixing.
Is there a limit on text size?
There is no hard limit. Large texts of 10,000+ lines work fine because everything is processed locally in your browser, though very large inputs may add a slight delay on slower devices.
Can I count lines of code?
Yes. Open the file in any editor, select all (Ctrl+A or Cmd+A), copy, and paste it here. The monospace line numbers and empty-line breakdown make it easy to read code-style line counts.
Is my text stored or sent anywhere?
No. All processing runs in your browser with JavaScript, and your text never leaves your device. You can confirm this by using the tool offline after the page has loaded.
