A hybrid typeface combining LINE Seed KR (Korean/CJK) and Lexend (Latin) into a single, harmonious font family.

Designed by Insung Cho.

SungSans pairs the two fonts with carefully chosen weight mappings so that Korean and Latin text appear visually balanced side by side:

The slash character (/) always follows the Seed weight to preserve Korean typographic consistency.

fonts/
  ttf/          Source TTF — for desktop / app use
  woff2/        Full WOFF2 — for web use (single file per weight)

webfonts/
  sungsans.css          @font-face using full WOFF2
  sungsans-dynamic.css  @font-face with unicode-range subsets (recommended for web)
  subset/       Per-range WOFF2 subsets — browsers download only what's visible

body {
  font-family: 'SungSans', sans-serif;
  font-weight: 400;
}

Browsers only download the unicode subsets actually rendered on screen — significantly faster for pages that mix Latin and Korean.
