Free Online Line Counter - Count Lines, Words & More in Any Text

The Delimiter.site Line Counter gives you a full breakdown of any text by line - total line count, non-empty lines, empty lines, total word count, average line length, and longest line - all updating in real time as you paste or type.

What Does the Line Counter Measure?

Counting lines is a fundamental task in data wrangling, code review, and content editing. This tool provides six statistics that between them answer every common line-counting question.

Total Lines

Every newline character in your text creates a new line. A file with 100 newlines has 101 lines by the standard convention used here (matching wc -l + 1). Empty text returns zero lines.

Non-Empty Lines

Lines that contain at least one non-whitespace character. If you are counting the actual content lines in a file - ignoring blank separators between sections - this is the number you want.

Empty Lines

Lines that are entirely blank (zero characters or only whitespace). Knowing the empty line count helps when checking whether a file has unexpected padding or when verifying that a data export has no missing rows.

Total Words

Word count across the entire text, identical to the Word Counter's figure. Useful when you need both line and word counts at the same time without switching tools.

Average Line Length

The mean number of characters per line, rounded to the nearest integer. Programming style guides often recommend keeping lines under 80 or 120 characters; this stat tells you whether your file is within those guidelines on average.

Longest Line

The character count of the single longest line in your text. If you are enforcing a maximum line length - in code, config files, or formatted text - this tells you immediately whether any line violates the limit.

How to Use the Line Counter

Step 1 - Paste Your Text

Click Paste to pull content from your clipboard, or type directly. All stats update instantly - there is no convert button.

Step 2 - Read the Stats Panel

The Lines card is the primary stat, shown larger. The other five cards display beside it so you get the full picture at a glance.

Step 3 - Clear and Start Over

Press Clear to wipe the input and reset all counters to zero.

Common Use Cases

Counting Rows in a Data Export

CSV and TSV exports often need a quick sanity check - does this file have the expected number of rows? Paste the content and read the total line count. Subtract one for the header row to get the data row count. For duplicate rows, run the list through the duplicate remover afterwards.

Checking Code File Size

Lines of code (LOC) is a basic software metric. Paste the contents of a file to count its lines before deciding whether it needs to be split into smaller modules.

Verifying Batch Import Files

When preparing a bulk import file for a CRM, email platform, or database, you need to know the exact row count to verify it matches the system's confirmation after import. The line counter gives you that number instantly.

Enforcing Line Length in Configuration Files

Many tools - nginx configs, YAML files, .env files - become hard to read when lines are too long. Use the Longest Line stat to catch any lines that exceed your style guide's limit before committing.
