An honest note before you use this

Font size is controlled by whatever app you paste into, not by the text itself — copy-pasted characters can't actually get taller or wider the way a font-size setting can. What this tool offers instead are styles that take up genuinely more visual space in most fonts: extra-wide characters, and letters boxed inside their own squares or circles.

Three "bigger" looks

Wide uses fullwidth Unicode characters — noticeably wider than normal letters, with extra spacing.

Boxed Square puts each letter inside its own square, reading as bigger and more solid.

Boxed Circle does the same with circles instead of squares.
