Each line is measured with the browser's Unicode grapheme rules, so a joined emoji or a letter plus a combining accent counts as one visible character instead of several hidden code units. Your input remains untouched while the sorted copy and shortest and longest counts update on the right.

How do I sort lines by length?
Paste one item per line and this text length sorter arranges them by character count as you type. Choose shortest-first or longest-first order, then optionally trim spaces or remove blank and duplicate rows. The result stays stable when lines have equal lengths and runs entirely in your browser.

Who it's for
- Developers ordering test fixtures, log labels, CSS values or translation keys to expose unusually long entries.
- Writers and editors arranging headlines, captions or prompts by visual complexity before choosing a concise option.
- Data teams cleaning pasted columns and moving short codes or long outliers to the top for faster review.
- Teachers and puzzle makers grading vocabulary, clues or answers from the shortest item to the longest.
FAQ
Is my text uploaded anywhere?
No. Line splitting, character counting, cleanup and sorting all happen locally in your browser. The tool does not send the pasted list to a server, which makes it suitable for private notes, internal labels, unpublished copy and other text you do not want to upload.
Is the line length sorter free?
Yes. You can sort as many lists as your browser can comfortably hold without creating an account, installing an extension or paying. Paste the text, change directions and cleanup options, and copy the result as often as you need.
How many lines can I sort?
There is no fixed line limit in the tool. Practical capacity depends on your browser, memory and device speed. Ordinary pasted lists and large text columns sort instantly, while files with millions of rows are usually better handled by a desktop or command-line utility.
Do spaces and punctuation count toward line length?
Yes. Every visible character counts, including spaces and punctuation. Turn on Trim whitespace to remove leading and trailing spaces before measuring. Spaces inside a line remain part of its length because removing them would change the actual text.
How are emoji and accented letters counted?
The sorter uses the browser's Unicode grapheme segmenter when available. A joined emoji sequence and a base letter with a combining accent each count as one user-perceived character. Older browsers fall back to counting Unicode code points, which is still safer than basic UTF-16 string length.
What happens when two lines have the same length?
Equal-length lines keep the same relative order they had in your input. This stable tie rule avoids surprising alphabetical rearrangement and makes it easy to compare the sorted result with the source list, in both shortest-first and longest-first modes.
Can I remove blank or duplicate lines while sorting?
Yes. More options includes separate controls for trimming surrounding whitespace, removing empty or whitespace-only rows, and removing exact duplicate lines. Cleanup happens before character measurement, so the displayed shortest and longest counts match the final output.
