Line height settings

To ensure readability and visual consistency across multilingual interfaces, the default system font, Noto Sans, uses tiered line height settings across different language environments. Based on the typographical characteristics of each script, the line height strategy is divided into three categories:

• ① English-like Languages (Recommended Line Height: Font Size * 116%) These languages have glyph structures close to English, including scripts using Latin letters (excluding Vietnamese), Greek, Cyrillic, Hebrew, Armenian, and Georgian.
• ② Tall-character languages (Recommended Line Height: Font Size * 132%) These languages feature taller glyph structures that require extra vertical space, commonly found in South Asian, Southeast Asian, and certain Eastern language systems.
• ③ Compact Languages (Recommended Line Height: Font Size * 125%) Chinese, Japanese, and Korean consist of high-density block character structures. Although their overall visual presence is high, their vertical spacing requirements differ from Tall languages and must be configured separately to maintain rhythm and breathing room between text blocks.

Category	Languages	Line Height
English-like	English, Spanish, German, French, Italian, Portuguese (Brazil/Portugal), Dutch, Hungarian, Czech, Polish, Slovak, Turkish, Russian, Ukrainian, Serbian, Hebrew, Romanian	116%
Tall-character	Arabic, Hindi, Thai, Vietnamese	132%
Compact	Simplified Chinese, Traditional Chinese (HK), Traditional Chinese (TW), Japanese, Korean	125%

For the special fonts “Zepp OS Number” and “Zepp OS Number Condensed,” the recommended line height is: font size * 100%.
