Lines of Code Counter
Count the lines of code in a file or paste, separating code from blanks and comments.
A rough measure of size
Lines of code is a rough-and-ready measure of how big a codebase or file is. This counts the lines and separates them into actual code, blank lines and comments, which gives a more honest number than a raw line count — a file padded with blank lines and comments is not as large as it first appears.
Paste your code and see the breakdown.
A blunt metric, used sensibly
It is worth being honest that lines of code is a crude measure of almost anything that matters — it says nothing about quality, complexity or value, and judging productivity by it rewards verbose code over concise, well-thought-out code. Where it is genuinely useful is as a rough sense of scale: how big a file has grown, roughly how much there is to review, or comparing the size of two implementations. Treat the number as a ballpark for size, never as a measure of worth.
Lines of Code Counter FAQ
What does it separate the lines into?
Actual code, blank lines and comments, giving a more honest count than a raw total.
Is lines of code a good productivity measure?
No — it says nothing about quality or value, and rewards verbose code. It is only a rough measure of size.
Is my code uploaded?
No. The counting happens in your browser.
