A Guide to Seal Fonts: Which Typeface Should You Use?
The font on a seal does a lot of quiet work. It signals formality, era, and region before anyone reads a single character. Here's how the common families differ and how to choose.
The main font families
- Song / Ming (serif) — clean, even strokes with small serifs. Reads as modern and official, and stays legible even at small sizes or under aging effects. A safe default for most company seals.
- Seal script (篆体 / 篆書) — the traditional, ancient style with flowing, stylized strokes. It carries the most classical, authoritative feeling, which is exactly why it's associated with formal seals. The trade-off is legibility: it's beautiful but slow to read, so reserve it for short text.
- Kai / regular (楷体) — modeled on brush handwriting. Friendlier and more personal than Song, while still clearly legible. Common on personal and decorative seals.
Why seal script became the classic
Seal script predates the everyday scripts we read today, so it already looks old and ceremonial. For centuries it was the script of choice for carving physical seals, and that association stuck. When you want a seal to feel traditional and formal, seal script is the shortcut — just keep the text short so it stays readable.
Mixing scripts and languages
This is the part that trips people up. Simplified Chinese, traditional Chinese, Japanese, and Korean each have their own preferred type families, and a single font rarely covers all of them well. A typeface that renders simplified characters cleanly may fall back to a mismatched style for Japanese kanji or Korean hangul, producing uneven strokes within the same line.
If your seal combines scripts — say a Chinese name with an English sub-line, or Japanese with romaji — check that every character renders in a consistent weight and style. The seal generator ships CJK serif fonts (Noto Serif SC / TC / JP / KR) precisely so each language renders correctly rather than falling back.
Choosing for your seal
- Long ring text → Song. It packs in characters legibly.
- Short, formal text → seal script, for maximum gravitas.
- Personal or friendly tone → Kai.
- Mixed languages → confirm consistent rendering across scripts before committing.
The fastest way to decide is to try a few. Open the seal generator, type your text, and cycle through fonts to see which one carries it best. For how font choice fits with borders, the center element, and overall layout, see how to design a company seal and the different seal shapes.
