Typesetting Japanese and English on the same page

Bilingual typesetting is one of the more specific skills in Japanese graphic design. Getting Japanese and English to sit comfortably on the same page, at the same optical weight, without either script looking like an afterthought, takes more decisions than it might appear. This is a plain account of how that works in practice.

The core problem: two scripts, different proportions

Japanese characters (kanji, hiragana, katakana) are designed to sit in a square frame. Latin characters are not. A Japanese typeface set at 10pt and a Latin typeface set at 10pt will not look the same size on the page. The Japanese will typically appear larger, because its characters fill more of the em square.

The practical fix is to set the Latin type slightly larger than the Japanese, or to choose a Latin typeface with a tall x-height that brings it closer to the visual weight of the Japanese. Neither solution is universal. It depends on the specific typefaces and the context.

Choosing typefaces that work together

Not every Japanese typeface has a Latin companion. Many Japanese fonts include a basic Latin character set, but it is often poorly spaced and not designed for extended text. For serious bilingual work, it is usually better to pair a dedicated Japanese typeface with a separate Latin typeface chosen to complement it.

A common pairing for body text is a Japanese serif from a foundry such as Morisawa or from the Adobe library, set with a European grotesque or humanist serif for the Latin. The key is finding a Latin typeface whose stroke weight and overall colour on the page matches the Japanese at the adjusted size.

Line spacing and grid

Japanese text typically needs more line spacing than Latin text at the same point size, because the characters are denser. In a bilingual layout where Japanese and Latin text appear in the same column, the line spacing is set to accommodate the Japanese, which means the Latin text will have slightly more air around it than it would in a Latin-only layout. This is usually fine and sometimes an advantage.

The grid for a bilingual publication also needs to account for the fact that Japanese text set horizontally (yokogumi) and Latin text will often produce different line counts for the same amount of copy. Building in flexibility at the grid stage saves a lot of adjustment later.

Bilingual typesetting often comes up in editorial work. If you are planning a publication that runs in both languages, it is worth discussing the typesetting approach early in the brief, before the copy is finalised.
