Word Wrap Best Practices and Common Mistakes

The best word-wrap results come from choosing a width that matches the destination, deciding up front how to treat long URLs, and never wrapping already-wrapped text. Get those three habits right and your plain-text emails, comments, and docs will read cleanly everywhere. Here are the practices and pitfalls worth knowing.

Tip 1: Match the width to where the text will live

A width is only "correct" relative to its destination. Plain-text email traditionally wraps at 72 so quoted replies still fit inside 80; terminal output and README files target 80; some modern code style guides allow 100 or 120. Picking a width blindly leads to text that looks ragged in one place and cramped in another. Decide the destination first, then set the width to suit it.

Tip 2: Handle long words deliberately

Long words — usually URLs or file paths — are the classic edge case. Leaving break-long-words off keeps every word whole but lets those lines overflow past your width. Turning it on guarantees the width is never exceeded but can split a URL across two lines, which some readers then cannot click as one link. Choose based on the destination: keep URLs whole for clickable email, but allow breaking when a strict column limit matters more.

Tip 3: Never double-wrap

The most common mistake is wrapping text that was already hard-wrapped. The result is short, uneven lines because the old breaks are still there. If you are re-flowing text to a new width, first remove the existing line breaks, then wrap fresh at the width you want. That produces clean, even lines instead of a jagged mess.

Common mistakes at a glance

Mistake	Symptom	Fix
Wrong width for destination	Ragged or cramped lines	Set width to match where text lands
Broken URLs	Links split across lines	Keep break-long-words off for clickable links
Double-wrapping	Short, uneven lines	Remove old breaks first, then wrap
Lost paragraphs	Everything merges	Keep blank lines between paragraphs

Tip 4: Preserve intentional structure

Word Wrap keeps blank-line paragraph breaks and wraps each paragraph independently, so keep those blank lines in your source if you want the structure to survive. If your text has meaningful indentation or lists, review the output — hard wrapping is designed for prose, and pre-formatted blocks may read better left unwrapped.

FAQ

What width should I use for plain-text email?

72 columns is the traditional choice, because it leaves room for quote markers so replies still fit within 80. For terminal-facing text, 80 is standard.

How do I re-wrap text that is already wrapped?

Remove the existing line breaks first so the text flows as continuous paragraphs, then run Word Wrap at your new width. This avoids the short, uneven lines that double-wrapping causes.

Should I break long URLs?

Only if staying under the width matters more than keeping the link clickable. For email and chat, leave break-long-words off so URLs remain intact on one line.

Why did my formatting look wrong after wrapping?

Hard wrapping targets prose. If the source had meaningful indentation or pre-formatted blocks, those can look off — wrap only the prose sections and leave code or tables as they are.
