Scaled with the button, and deliberately smaller than the mark: 텍스트는 로고 높이보다 작은 크기를 사용해야 해요. 14.5 sp against an 18 dp mark at Height.

The size is the Hangul advance measured between successive syllable origins in the artwork (58 px at 4x), which for a Korean typeface is the em — a far steadier measurement than the ink height, which varies per syllable. Bold because the label's stems measure 2 dp against that 14.5 dp em, and 0.14 em is a bold weight, not a regular one.

In sp, so it respects the reader's font-size setting; a very large setting grows the button rather than clipping the label.
