Word Wrap Tool — Wrap Text at a Custom Character Width Instantly
Plain text emails must wrap at 72 characters per RFC 2822. Python docstrings should wrap at 72 per PEP 8; code at 79. This word wrap tool breaks your text at any specified column width — inserting real line break characters (hard wrap) at word boundaries, never mid-word. Paste a long paragraph, set the column limit, get correctly wrapped text. No signup, no character limit.
What Is Word Wrap?
A word wrap tool automatically breaks your text at a specified character width, inserting line breaks so no line exceeds the defined column limit. Enter your character width (80, 72, 100, or any custom value) and the tool reformats your text to fit within that width, breaking at word boundaries to avoid splitting words in the middle.
Word wrap at specific widths is essential for several technical contexts. Email plain-text standards recommend wrapping at 72–78 characters to ensure readability across all email clients. Unix convention in code files is 80 characters. Many documentation standards use 100 or 120 characters. Terminal output benefits from wrapping at terminal width (typically 80 or 120) for clean display. Monospace code files in version control also benefit from consistent line lengths that make diffs easier to read and review.
A very long line of text...→Wrapped at 80 charsKey Features
Inserts actual newline characters at word boundaries so text fits within any column limit — 72, 79, 80, 100, or any custom value. This is real hard wrap, not visual soft wrap.
Wrapping only occurs at space boundaries. Long single tokens (URLs, file paths, identifiers) stay on their own line rather than being split at an arbitrary character position.
A slider or input field lets you set the exact character limit and see the wrapped result immediately — no submit button required. Adjust until the output fits your target context.
Wrapping runs locally — no data leaves your device. Safe for confidential emails, proprietary documentation, and internal technical content.
When to Use Word Wrap
Use when pasting text into terminals, code comments, email clients, or any fixed-width context with a column limit.
The default width is 80 characters — the traditional terminal width. Adjust the slider for wider or narrower output.
Who Should Use This Tool?
Wrap plain-text email content at 72 characters per line — the recommended width for maximum email client compatibility.
Format code comments, README files, and documentation at 80 or 100 characters per line to match project or language style guides.
Wrap configuration file comments and shell script text at terminal-width limits for clean, predictable display in terminal environments.
Key Use Cases
- →Wrap plain-text email content at 72 characters for RFC-compliant email formatting that displays correctly in all clients.
- →Format README.md and documentation files at 80 or 100 characters to match project contribution style guides.
- →Wrap terminal output and shell script comments at 80 characters for display on standard terminal window widths.
- →Reformat imported content from a narrow-width source to a wider display target by rewrapping at a new character limit.
- →Prepare code review patches and diff outputs at consistent line lengths to improve readability in side-by-side diff views.

This Converter vs Manual Methods
Why use this tool instead of doing it by hand?
| Method | Limitation |
|---|---|
| Manually inserting line breaks | Extremely tedious for long paragraphs or documents; breaks require recount on any text change |
| Word/Google Docs auto-wrap | Does not insert actual line break characters — not a hard wrap; unsuitable for email or code |
| Python textwrap module | Requires Python interpreter and coding knowledge |
| fmt/fold Unix commands | Requires terminal access; not available on Windows by default |

Common Mistakes & Pro Tips
- !Wrapping structured content like Markdown tables, code blocks, or JSON — hard wrapping these will break their formatting and structure. Only wrap natural-language paragraphs and comment text, not structured data.
- !Confusing visual wrap with hard wrap — most text editors and word processors do visual (soft) wrapping that adjusts to window width without inserting actual line break characters. Word wrap for emails and code files requires hard wrap: actual \n characters inserted in the text at the column boundary.
- !Wrapping and then editing the wrapped text — once hard line breaks are inserted, adding a sentence to the middle of a paragraph will push subsequent lines past the column limit. Hard-wrapped text must be re-wrapped after any editing. Best practice: edit content in paragraph form with no hard wraps first, then apply word wrap as the final step before publishing, sending, or committing.
Frequently Asked Questions
Everything you need to know about Word Wrap
What is the difference between hard wrap and soft wrap?
+
Soft wrap (visual wrap) is what your text editor and browser do by default — text flows to the next visual line when it reaches the edge of its container, but no actual newline character is inserted. The text is one long line in storage. Hard wrap inserts actual newline characters (\n) at the wrap point, making each visual line a separate line in the underlying text. Email, terminals, and some documentation systems require hard wrap.
Why do emails use 72 or 78 character line limits?
+
Email standards RFC 2822 and RFC 5321 recommend lines no longer than 78 characters in plain-text email for compatibility across all mail transfer agents and email clients. The 72-character convention leaves a 6-character margin of safety for quoted reply indentation ("> " prefix adds 2 characters per level of quoting). Long lines may be broken by mail servers, potentially mid-word, so wrapping at 72 prevents server-introduced breaks.
Should code lines be limited to 80 characters?
+
The 80-character limit traces back to 80-column terminal displays from the 1970s. It remains a common convention: PEP 8 (Python) sets 79 characters for code, 72 for docstrings. Most JavaScript and TypeScript projects use 80 or 100. Google's style guides use 80 for most languages. Many teams now use 100 or 120, reflecting modern widescreen displays. The practical goal: lines that fit comfortably in a standard split-editor view without horizontal scrolling.
Does word wrap work on text with existing line breaks?
+
Most word wrap tools first unwrap the existing text (joining lines that were manually wrapped at the old width) then rewrap at the new width. This prevents cumulative wrapping where already-short lines get wrapped again. If your tool doesn't auto-unwrap, run Remove Line Breaks first to join the text into flowing paragraphs, then apply word wrap at the new target width.
What happens to long URLs and non-breaking content?
+
URLs and long identifiers that exceed the wrap width present a challenge. A URL that is 120 characters cannot be wrapped at a word boundary without breaking the URL. Most word wrap tools include the URL on its own line if it's the only token that exceeds the limit, or may break at the closest word boundary before or after the URL. For email and documentation, long URLs are typically placed on their own line or converted to short links.
Why does RFC 2822 specify 78 characters and email clients often recommend 72?
+
RFC 2822 sets a hard maximum of 998 characters per line and a soft recommended limit of 78 characters for readability. The 72-character convention leaves a 6-character buffer for quoted-reply indentation: each level of "> " quoting adds 2 characters, and a message quoted three times deep adds 6 characters. A 72-character original line stays within the 78-character recommendation even after three levels of quoting — the practical safe choice for widely-forwarded plain-text emails.
How does Python's textwrap module handle word wrapping compared to this tool?
+
Python's textwrap.wrap(text, width=79) is the programmatic equivalent — it returns a list of strings each no longer than the width, breaking at word boundaries. textwrap.fill(text, width=79) joins them with newlines. The Python module also handles indentation (initial_indent, subsequent_indent), long-word breaking (break_long_words=True), and URL preservation via break_on_hyphens. Our browser tool provides the same core functionality without requiring a Python environment, making it the fastest path for ad-hoc wrapping tasks.
