ASCII Box Drawing Generator

Surround any text with a real box frame, measured in true terminal display width — CJK and emoji count as two columns, so the corners always line up.

About this tool

Widths are computed per code point the way a terminal does it — combining marks and joiners add nothing, while CJK, Hangul, full-width forms and emoji occupy two columns — so boxes stay square even with mixed scripts, and thin emoji are padded rather than letting the right edge drift. In fixed-width mode long lines wrap on real display width and every row is padded to the exact same column count. Everything is generated locally in your browser.
