This online line counter updates in real time — no button click needed:
Click the text area and paste or type your content — code, a list, a document, or any multi-line text.
Total lines, non-empty lines, empty lines, and word count all update as you type.
Compare non-empty vs empty lines to understand content density, or use word count alongside line count for readability analysis.
For developers counting lines of code, pair this with our Word Counter to get full text statistics — words, characters, and sentences alongside your line count.
A line counter — also called a line count tool, blank line counter, or text line analyzer — counts the number of lines in any block of text, distinguishing between total lines, non-empty content lines, and blank/empty lines.
It is used by developers checking code length, writers counting paragraphs, data professionals processing structured text files, and SEO specialists analysing content structure. All counting happens locally in your browser — your text never leaves your device. For data files with duplicate lines, our Reverse Lines and Sort Lines tools complement this counter for full line-level text processing.
