What Is Wrap Lines?
Wrap Lines is a text tool that breaks long lines at a specified character width. It splits lines at word boundaries whenever possible and only hard-breaks individual words that exceed the maximum width. This is useful for formatting text to fit within fixed-width displays, terminals, or code editors.
The output updates in real time as you type. This tool runs entirely in your browser — no text is sent to any server.
How to Use This Tool
Enter Your Text
Type directly into the input editor, paste content with Ctrl+V, or upload/drag a .txt file.
Set the Max Width
Enter the maximum number of characters per line (default is 80). The minimum is 10 and the maximum is 1000.
See Results Instantly
The wrapped output appears in real time in the right panel as you type or adjust the width.
Copy or Download
Use Copy to copy the wrapped text to clipboard, Download to save as a .txt file, or Clear to reset.
Features Explained
Word-Aware Wrapping
▼
Lines are broken at word boundaries (spaces) so words are not split in the middle. If a single word is longer than the max width, it is hard-broken into chunks to ensure every line fits within the limit.
Configurable Width
▼
Set the maximum line width from 10 to 1000 characters. Common values include 72 (email), 80 (terminal standard), 100 or 120 (wide code editors).
Real-Time Processing
▼
The output updates instantly as you type or change the width. No need to click a button to see results. The computation is memoized for performance.
File Upload & Drag and Drop
▼
Upload a .txt file using the Upload button or drag and drop a text file directly onto the input area. The file contents replace the current input text.
Who Is This Tool For?
Developers
Format code comments, README files, and commit messages to fit within 72 or 80 character line limits.
Writers & Editors
Wrap long paragraphs for plain-text emails, fixed-width newsletters, or documents with column constraints.
System Admins
Format log messages, configuration comments, and terminal output to fit standard 80-column displays.
Email Users
Wrap email body text at 72 characters following the widely recommended plain-text email formatting convention.
Students

Content Creators
Prepare text for platforms or systems that require fixed-width formatting, like ASCII art or terminal-based content.
Common Line Width Standards
| Width | Standard | Common Use |
|---|---|---|
| 72 | Email / Git commits | RFC 2822 recommended line length for plain-text emails and Git commit messages |
| 80 | Terminal standard | Classic terminal width, used in most coding style guides and linters |
| 100 | Modern code editors | Wider limit for modern screens, used by Google and some open-source style guides |
| 120 | Wide displays | Common in IDE-based development where screens are wide enough for longer lines |
| 40 | Narrow columns | Mobile-friendly text, narrow UI panels, or side-by-side editor views |
| 132 | Legacy mainframe | IBM mainframe terminal width, still used in some enterprise environments |
Tips for Wrapping Lines
Use 72 for Git commit messages
Git conventions recommend wrapping the commit body at 72 characters so it displays well in terminals and git log output.
Use 80 for code comments
Most style guides (PEP 8, Google, Linux kernel) recommend 80 characters. Set width to 80 for clean, standard-compliant comments.
Preview before pasting
Wrap your text here first, then paste into your target — emails, docs, or code. The real-time preview lets you adjust until it looks right.
Long URLs won't break cleanly
URLs and long unbroken strings will be hard-broken at the max width. Consider placing long URLs on their own line before wrapping.
Combine with other tools
Use Wrap Lines with Remove Extra Spaces or Remove Empty Lines to clean up text before wrapping for the best results.
Upload large files
For long documents, use the Upload button or drag and drop instead of pasting. The tool handles large files efficiently in the browser.
