How do I put a box around my text?

Paste or type your text in the input, one line per row, and the box appears instantly on the right. The tool measures your longest line and draws a frame that fits it exactly. For a quick comment banner, type a single line like "Section: Auth", set style to single and padding to 1, and you get a ┌──────────────┐ box you can paste above a function. No counting characters, no manual dashes.

What is the difference between single and double border styles?

Single uses the light box-drawing run ┌─┐ │ └─┘ and reads as a quiet divider. Double uses ╔═╗ ║ ╚═╝, which is heavier and stands out, so people reach for it on a file header or a warning block. They render identically in any monospace font that ships box-drawing glyphs. If you need something even bolder, the bold style ┏━┓ uses the heavy line set.

Why do Chinese characters break the box in other tools?

Most simple generators count characters, but a Chinese character such as 中 occupies two columns in a terminal while the letter a occupies one. Counting both as 1 leaves the right edge ragged. This tool measures display width: CJK, kana, Hangul and fullwidth forms count as 2, so a line of 中文 and a line of English end on the same column. Try mixing 你好 and Hello and the right border stays straight.

How do I make a comment banner for my source code?

Pick the ascii style (+--+ with | edges) so the banner survives in files viewed without Unicode, set padding to 1, and type your heading. Copy the result and paste it inside a /* */ or # comment block. For a section header inside a long file, add a title like "DATABASE" and the tool draws a +-------+ divider under it, giving a two-tier banner that scans well in a diff.

What does the rounded style look like and when should I use it?

Rounded swaps the sharp corners for ╭ ╮ ╰ ╯ while keeping the same ─ │ edges, so the box reads softer. It looks at home in README headings, CLI welcome screens and chat snippets where the hard corners of single feel too rigid. Note that rounded corners are Unicode-only, so use ascii instead if the output has to render in a plain ASCII context such as an old log viewer.

Section banners inside source files

You are reading a 600-line file and every section blurs together. Type "AUTH HANDLERS", pick ascii with padding 1, copy the +-----+ box, and paste it as a comment above the block. Now the file scans like a table of contents and a reviewer can jump to a section in the diff without scrolling line by line.

README and CLI headings that pop

A plain markdown heading disappears in a wall of text. Wrap your project name in a rounded ╭──╮ box, copy it into a fenced code block at the top of the README, and the title gets a frame that renders the same on GitHub, in a terminal and in a chat paste. The double style works the same way for a louder banner.

Aligning mixed Chinese and English notes

You keep a bilingual cheat-sheet where some lines are 中文 and some are English. Counting characters by hand leaves the right edge ragged. Paste all the lines, and the width-aware engine doubles the CJK columns so the box closes flush on every row, ready to drop into a wiki or a terminal MOTD.

Warning and callout blocks in plain text

Email, plain-text tickets and code review comments have no rich formatting. A double ╔══╗ box around "DO NOT MERGE, failing tests" turns an ignorable sentence into a block that the reader cannot skim past. Copy it straight into the comment field; it survives any system that uses a monospace font.

What this tool does

A text box drawing generator that wraps any text in a clean ASCII or Unicode frame. Pick from six border styles: single (┌─┐), double (╔═╗), rounded (╭─╮), bold (┏━┓), plain ascii (+--+) for terminals that lack Unicode, and a stars (***) banner. The box auto-sizes to your widest line, so a five-line block lines up on the right edge without you counting columns. Wide characters are handled properly: a Chinese, Japanese or fullwidth character takes two terminal columns, and the alignment math doubles them so mixed 中文 / English lines never drift. Add inner padding, choose left, center or right alignment, and drop in an optional title row that gets its own ├──┤ divider. Everything runs as plain JavaScript in the page, the input round-trips through the URL so a share link reopens your exact box, and one click copies the result ready to paste into a code comment, README heading or terminal banner.

Real-world use cases

Section banners inside source files
You are reading a 600-line file and every section blurs together. Type "AUTH HANDLERS", pick ascii with padding 1, copy the +-----+ box, and paste it as a comment above the block. Now the file scans like a table of contents and a reviewer can jump to a section in the diff without scrolling line by line.
README and CLI headings that pop
A plain markdown heading disappears in a wall of text. Wrap your project name in a rounded ╭──╮ box, copy it into a fenced code block at the top of the README, and the title gets a frame that renders the same on GitHub, in a terminal and in a chat paste. The double style works the same way for a louder banner.
Aligning mixed Chinese and English notes
You keep a bilingual cheat-sheet where some lines are 中文 and some are English. Counting characters by hand leaves the right edge ragged. Paste all the lines, and the width-aware engine doubles the CJK columns so the box closes flush on every row, ready to drop into a wiki or a terminal MOTD.
Warning and callout blocks in plain text
Email, plain-text tickets and code review comments have no rich formatting. A double ╔══╗ box around "DO NOT MERGE, failing tests" turns an ignorable sentence into a block that the reader cannot skim past. Copy it straight into the comment field; it survives any system that uses a monospace font.

Common pitfalls

Using a Unicode style like rounded or double where the output will be read in a plain-ASCII context. An old log viewer or a terminal without box-drawing glyphs renders ╔ as garbage. Switch to the ascii style so the box survives anywhere.
Assuming a Chinese line and an English line of the same character count will line up. They will not in a width-counting tool, because 中 is two columns wide. This generator measures display width, but if you hand-edit the output afterwards you can still break the alignment.
Forgetting that the box auto-sizes to the longest line, then pasting in one very long line by accident. The whole box stretches to fit it. Trim or wrap that line first, or the banner becomes far wider than the surrounding code.

Privacy

The whole tool is plain JavaScript that runs in your browser tab. Your text, title and style choices are turned into a box on the page and never sent to a server, and nothing you type is logged. The one thing to know: your input round-trips through the URL query string so a share link can reopen the same box, which means a link you paste into chat will record that text in the recipient server's access log. For anything sensitive, use the copy button and paste the box rather than sharing the URL.
