Word Wrap Use Cases: Email, Code Comments, and READMEs

Word wrapping earns its keep anywhere plain text must fit a fixed width — email bodies, code comments, README files, and commit messages all read better when no line runs past a set column. Here are the concrete scenarios where the Word Wrap tool fits into a real workflow, each with a worked example.

Example 1: Formatting a plain-text email

You have drafted a long message in an editor and need it to display cleanly in older mail clients and quoted replies. Paste it into Word Wrap, set the width to 72, and copy the result back. Every line now fits, and because paragraph breaks are preserved, the message keeps its structure. This is especially useful for mailing-list posts and support tickets where monospaced display is common.

Example 2: Keeping code comments under 80 columns

A block comment that runs off the screen breaks a team's 80-column style guide. Copy the comment text, wrap it at 80, and paste the tidy version back above your function. Words stay whole so identifiers are not split awkwardly, and reviewers no longer have to scroll horizontally to read your explanation.

Example 3: Tidying a README or changelog

Documentation that mixes long and short lines looks careless in a diff. Wrapping prose sections to a consistent width — often 80 — makes the file read evenly in any editor and produces cleaner, more reviewable diffs when you commit changes. Leave code blocks and tables untouched and wrap only the paragraphs.

Example 4: Writing a conventional commit message

Git conventions favour a short subject line and a body wrapped near 72 columns so git log reads well in a terminal. Draft your body, wrap it at 72, and paste it into your commit. The message now displays correctly across terminals and Git tools without manual line breaking.

Which width for which job

Use case	Suggested width	Long words
Plain-text email	72	Keep whole (clickable links)
Code comments	80	Keep whole
README / changelog	80	Keep whole
Commit message body	72	Keep whole

In each case the text never leaves your browser, so internal emails, private repos, and unreleased docs stay on your device — and the tool works offline once loaded.

FAQ

What width should a commit message body use?

Around 72 columns is the common Git convention, so the body reads well in a terminal alongside the indentation that git log adds.

Can I wrap only part of a document?

Yes. Paste just the prose section you want to reflow — leave code blocks, tables, or pre-formatted text out so their layout is not disturbed.

Will wrapping help my diffs?

Consistently wrapped prose produces smaller, cleaner diffs because a change touches only the affected lines rather than reflowing a whole paragraph.

Is it safe to wrap internal or confidential text?

Yes. All wrapping happens locally in your browser and nothing is uploaded, so internal emails and private docs stay on your machine.
