Heiti SC Medium is arguably the most important weight in the family for User Interface (UI) design.
Heiti SC Medium has a neutral, almost cold personality. Pair it with:
Avoid pairing it with highly stylized serifs like Didot or slab-serifs like Rockwell—the contrast in mood is too jarring.
If you are a designer working on modern Apple platforms, you may have noticed Heiti SC being supplanted by PingFang SC. Heiti sc medium font
For years, Heiti SC was the standard. However, starting with iOS 9 and macOS El Capitan, Apple introduced PingFang SC. PingFang is a completely new design by DynaComware that is even more optimized for high-resolution "Retina" displays. PingFang has more weights (from UltraLight to Semibold) and a slightly more open, airy design compared to the denser, older Heiti SC.
While PingFang is now the default system font, Heiti SC Medium remains installed on millions of devices and is often used as a legacy fallback or for designs that specifically require its specific historical weight and density.
To understand Heiti SC, one must dissect the name: Heiti SC Medium is arguably the most important
For a long time, Apple used Hiragino Sans GB (developed by the Japanese foundry SCREEN) as the default Simplified Chinese font. While beautiful, it was a Japanese take on Chinese characters, leading to subtle stroke discrepancies that purists disliked.
Let us break down the name first. Heiti (黑体) is the Chinese term for a sans-serif or "black" typeface. In the Western classification system, it is the equivalent of a Gothic or grotesque sans-serif. SC stands for Simplified Chinese, indicating that the font contains glyphs for the Simplified Chinese writing system used in mainland China (as opposed to TC for Traditional Chinese). Medium refers to the specific weight—sitting comfortably between Regular (lighter) and Bold (heavier).
In technical terms, Heiti SC is Apple’s default Simplified Chinese system font. It is the native typeface for all user interface elements, menus, alerts, and system apps on iPhones, iPads, and Macs localized for the Chinese market. The Medium weight is specifically optimized for on-screen legibility at medium to large sizes, such as headlines, subheadings, and emphasized body text. Avoid pairing it with highly stylized serifs like
Because Chinese characters are monospaced in width (each occupies an ideographic square), zoom in to check your line height. For Heiti SC Medium at 16px, a line height of 1.5 (24px) is optimal. Reduce letter-spacing (tracking) to 0; this font does not require additional spacing.
Due to its medium weight and clean sans-serif design, Heiti SC Medium is a favorite for burned-in subtitles. It resists anti-aliasing artifacts (blurry edges) better than lighter fonts.
