How to Wrap Text at a Set Width and Add Line Numbers
Enter text, choose a width from 10 to 500 for non-empty input, and optionally enable line numbering. The tool wraps each newline-separated line by spaces and returns the processed text with line metadata.
What the text wrapper does
Word Wrap & Line Numbers formats supplied text to a chosen line width and can add line numbers to the processed lines. It is useful when you need a readable text block for a fixed-width layout, a quick review, or a numbered draft.
The tool works with newline-separated input. For non-empty text, it processes each original line separately and wraps longer lines by accumulating space-separated words until adding the next word would exceed the effective width. Text is optional, so you can also submit an empty input successfully.
How to wrap text and add line numbers
- Enter or paste the text you want to format. You may leave the text empty if you only need to confirm the empty-input result.
- Choose a width. If you enter non-empty text, a missing or falsy width uses 80. Otherwise, the supplied width is converted to an integer and constrained to the range 10 through 500. The empty-text path retains the supplied width without applying that non-empty-text normalization.
- Turn line numbering on if you want each processed line labeled. Leave it off for wrapped text without prefixes.
- Run the tool and review the processed text. For non-empty input, each original newline-separated line is handled in turn. Lines that fit the effective width remain intact; longer lines are assembled from space-separated words.
- Use the returned line count, effective width, and original newline-separated line count to check the result. If line numbering is enabled, labels use one-based numbering in a four-character field followed by two spaces.
For a quick check, paste a short paragraph, select a width such as 40, and enable numbering. Then compare the formatted lines with the selected width and confirm that the labels appear in sequence.
How to read the result
The processed text is the main result. With non-empty input, the accompanying metadata reports the number of resulting lines, the effective width used for processing, and the number of newline-separated lines in the original text. These values help distinguish a paragraph that was reflowed from input that already contained several lines.
An empty submission is still successful: the processed text is empty and the resulting line count is zero. In that case, the supplied width is retained rather than passed through the non-empty-text width normalization.
The width is not a character-by-character hard break. A space-separated word longer than the effective width is not split into smaller pieces, so a resulting line can exceed the selected width in that situation. The verified wrapping behavior also does not promise preservation of arbitrary spacing or punctuation-aware, language-aware, or paragraph-aware formatting. It uses newline separation and spaces between words.
When numbering is enabled, the numbers identify processed lines starting at one; they are not part of the original text’s content. The declared contract indicates that the tool does not use network access, but that fact does not establish a particular deployment environment or a storage or privacy policy.
Worked example
You are preparing a short project note for review and want its lines wrapped at width 20 with visible line numbers.
Paste the sentence into the text field, set the width to 20, turn on line numbering, and run the tool.
The result contains processed text, a resulting line count, the effective width, and the original newline-separated line count. If numbering is enabled, the processed lines also have one-based labels with the documented spacing.
Limitations
- Words longer than the effective width are not split, and the wrapping behavior is based on newline separation and spaces between words. The declared contract indicates no network access, without establishing storage, privacy, or deployment details.
Common errors
- A long unbroken word may extend beyond the selected width because the wrapping logic does not split a space-separated word. If that matters, shorten the word or add suitable spaces before processing.
FAQ
What width can I use?
For non-empty text, a supplied width is converted to an integer and constrained to 10 through 500; a missing or falsy width uses 80. Empty text follows a separate path and retains the supplied width.
Can I add line numbers to the wrapped text?
Yes, but only when line numbering is enabled. Each processed line receives a one-based number aligned to a four-character field followed by two spaces.
Why is one line longer than the selected width?
A word longer than the effective width is not split into smaller pieces, so its line can exceed the selected width. The tool wraps by accumulating space-separated words rather than breaking every character.
