Free Online Line Counter
Count lines in any text instantly. See a numbered line preview with per-line character counts, blank-line stats, and line-length distribution — free and private.
What is a Line Counter?
A line counter is an online tool that counts the number of lines in any block of text. Our free online line counter goes beyond a basic count — it gives you a complete line-by-line breakdown including total lines, non-empty lines, blank lines, average characters per line, and the longest line in your text.
Every time you press Enter you create a new line. A line counter counts those line breaks and reports the total. This matters in many contexts:
For developers and programmers, line count is a standard code metric. Knowing the lines of code (LOC) in a file or script helps with code review, documentation, and project sizing. Most version-control tools and editors show LOC for exactly this reason.
For writers and poets, specific poetic forms require exact line counts. A sonnet has 14 lines. A haiku has 3. A villanelle has 19. A limerick has 5. Our numbered line preview makes it easy to see exactly where you are in a structured poem or lyric.
For content creators and SEO professionals, meta descriptions, ad copy, and social media posts often have per-line or per-paragraph limits. Counting lines helps format content before pasting it into a CMS or ad platform.
For data analysts, when working with CSV files, log files, or any line-delimited data, knowing the exact line count tells you the number of records in your dataset.

How to Use Our Line Counter
Using our free line counter is simple. Paste or type any text into the editor above — the line count updates instantly with no need to click anything.
The Quick Stats strip below the editor shows your total lines, non-empty lines, empty lines, word count, and character count at a glance. The sidebar shows the hero line count alongside line-length statistics and a bar chart of line-length distribution.
Below the editor, the Numbered Lines panel shows every line with its number, full content, and character count. Blank lines are shown as "— empty line —" so they are easy to spot. The longest line gets a highlighted badge for quick identification.
Options:
- Exclude blank lines — toggle this to hide blank lines from the count and preview. The hero counter switches to show only non-empty lines. Great for counting meaningful content lines in code, lists, or prose.
- Trim whitespace — toggle this to strip leading and trailing spaces before counting each line's character length. Useful when copy-pasted text has inconsistent indentation.
Pro tips:
- Paste a CSV file to instantly see its record count (one row per line)
- Paste Python, JavaScript, or any code to count lines of code
- Paste a poem to verify it has the right number of lines for your chosen form
Frequently Asked Questions
How does the line counter count lines?
Lines are counted by splitting your text at every newline character (\n). Each break creates a new line. An empty line (where you pressed Enter twice) is counted as one line with no content. The total line count always includes blank lines unless you toggle 'Exclude blank lines'.
What is the difference between total lines and non-empty lines?
Total lines includes every line including blank ones — every time you pressed Enter. Non-empty lines counts only lines that contain at least one non-whitespace character. The difference between the two is your blank-line count.
How do I count lines of code?
Paste your code into the editor above. The total lines stat gives you the raw line count. Toggle 'Exclude blank lines' to get a count of non-blank lines only, which approximates logical lines of code. For the most accurate LOC metric, also ignore comment-only lines — you can count those visually in the numbered preview.
How many lines is a sonnet?
A traditional sonnet has exactly 14 lines, typically arranged in four stanzas. A Shakespearean sonnet is three quatrains (4 lines each) plus a couplet. A Petrarchan sonnet is an octave (8 lines) plus a sestet (6 lines). Use our numbered line preview to count your poem's lines precisely.
Can I count lines in a CSV file?
Yes. Paste your CSV content into the editor. Each row in a CSV file occupies one line, so the total line count tells you the number of rows. If your file has a header row, the data record count is total lines minus one. Toggle 'Exclude blank lines' to ignore any trailing blank rows.
Is my text stored anywhere?
No. All counting runs entirely in your browser using JavaScript. Your text is never sent to any server. We do save your text in your browser's local storage so you don't lose your work if you close the tab — but this data stays on your device only.
What is the average line length stat?
Average line length shows the mean number of characters across all non-empty lines in your text. This is useful for formatting checks — for example, most style guides recommend code lines stay under 80 or 120 characters. If your average is high, you may have lines that need wrapping.
Does this work for code in any programming language?
Yes. Our line counter works with plain text and any programming language — Python, JavaScript, Java, C, C++, Ruby, PHP, SQL, HTML, CSS, Bash, and more. Just paste your code and the numbered preview shows every line.
