Need to know exactly how many lines a block of text takes up — for a form field with a line limit, a poem with a fixed number of verses, or a list you're about to paste somewhere with a row cap? This page opens the line counter ready for exactly that: paste your text and the total updates immediately.

The total line count follows how a text editor numbers lines, so trailing blank lines and empty lines in the middle both count — nothing is silently dropped or merged. Alongside the total you also get the non-empty line count, the blank line count, the longest line's length and the average line length, all live.

Nothing you paste here is uploaded: the count happens entirely in your browser, so drafts, private lists and unpublished text stay on your device.

Accepted Formats & Rules

  • Live total line count, non-empty line count and blank line count.
  • Longest line length and average line length, both in characters.
  • Handles pasted files of any size, including full source code, without sending data to a server.

Key Benefits

✓ Complete privacy: the text is counted entirely in your browser and never leaves your device.
✓ Instant feedback: every stat updates live with each keystroke — no button to press.
✓ Editor-accurate counting: the total line count matches what your code editor's line numbers would show, including trailing blank lines.

Use Cases

  • • Check a script, subtitle file or config against a strict line-count limit before submitting or uploading it.
  • • Paste a source file or diff to see how many lines actually contain code versus how many are blank padding, without opening an editor.
  • • Get a live read on a pasted list or poem's structure — total lines, blank lines, and the longest line's length — as you write or edit it.
