Line Length Checker
Check the character length of every line against a limit
Paste a list of titles, URLs or other short strings, one per line, and see the character length of each one next to a maximum length you set, plus the shortest, longest and average length and how many lines are over the limit. Runs entirely in your browser.

What this tool does
SEO titles, meta descriptions and URL slugs each have a practical length limit, and checking a batch of them one at a time against a counter is slow. This tool measures every pasted line at once against the limit you set, so the lines that need trimming are obvious before they go live.
How to use it
- Paste your list, one line per item, such as page titles or URL slugs.
- Set the maximum length you want to check against.
- Read the length next to each line and the summary stats above the result.

Frequently asked questions
- Is my list uploaded anywhere?
- No. Measuring happens in JavaScript running in the page, so nothing you paste ever leaves your device.
- Does the length count bytes or characters?
- It counts Unicode characters, the same way a person reading the line would count them, so an accented letter or emoji counts as one character even though it may take more than one byte to store.
- What counts as "over limit"?
- Any line whose character count is strictly greater than the maximum length you set; a line exactly at the limit is not flagged.
