How to use Text Alignment and Justification Tool

Paste the paragraphs and set a width between 10 and 200 characters.
Choose left, right, center or full justification.
Choose whether words longer than the width may split.
Inspect the aligned text in a monospace view before copying it.

Example: Text Alignment and Justification Tool

A local worked example using the inputs and settings below for text alignment and justification tool.

You add

Text: "Alignment controls where the extra space in a line goes.\n\nA justified paragraph spreads the space between its words and keeps the final line left aligned." Line width: "72" Alignment: "left" Split words longer than the width: false

You get

Aligned 3 lines across 2 paragraphs to 72 code points with left alignment.

Options

Width: Width counts Unicode code points. It does not measure proportional fonts, terminal cells or complete emoji sequences.
Justification: Full justification distributes spaces on interior lines and keeps the paragraph’s final line left aligned. Splitting long words is a separate choice.

Supported inputs and limits

Up to 1,000,000 input characters and widths of 10–200 code points. Blank-line paragraph boundaries remain; line endings become LF. Full justification adds spaces to interior lines and leaves the final line left aligned. Code-point counts are not display-cell widths: tabs, combining characters, emoji and proportional fonts can look different.

Alignment inserts real spaces and line breaks

This changes the plain text rather than an editor’s display setting. Blank lines separate paragraphs; wrapping can join original single line breaks. Review the result in a monospace view before replacing a file whose spacing carries meaning.

Questions about Text Alignment and Justification Tool

Why does the aligned result change in a proportional font?

This tool counts code points and inserts ordinary spaces. A proportional font gives letters different visual widths. Use a monospace view for the intended arrangement.

Is the last line of a justified paragraph stretched?

No. Only interior lines receive extra spaces; the final line remains left aligned.

What happens to a word longer than my width?

The long-word option determines whether it is split. Check the result, especially for URLs or identifiers that should stay together.
