Old Style Serif vs Transitional Serif
オールドスタイル・ローマン / トランジショナル
Both are text romans with bracketed serifs, and even the color of a set page comes out much the same.
How to tell them apart. If the thick part of a lowercase o leans on a slanted axis it is Old Style, and if it has risen close to upright it is Transitional.
Old Style Serif

Set the standard for text faces that read without fatigue: the pen's oblique axis and gentle stroke contrast.
Transitional Serif

Raising the axis toward vertical, sharpening the contrast between strokes and designing paper and ink along with the letter moved type past handwriting into an object made in its own right.
| Old Style Serif | Transitional Serif | |
|---|---|---|
| Era | 15th–16th century– | 18th century |
| Family | Type Classification | Type Classification |
| Kind | Style | Style |
| Cues | Oblique stress / Gentle contrast / Bracketed serifs / Modest x-height | Near-vertical axis / Strengthened contrast / Sharp horizontal serifs / Designed with polished paper |
| Best used for | Book and long form text meant to be read for hundreds of pages without fatigue · Magazines and annual reports with long copy that need a settled humanist voice | Textbooks and reference works that need clarity and dignity at the same time · Government and university publications balancing neutrality with authority |
| Type | Modest size with open leading, letting the gentle contrast do the work | Set slightly large and assume paper and press that hold the fine strokes |
| Composition | One column at a short measure, with asymmetric inner and outer margins | A poised single column with measure, leading and margins set in proportion |
| Material | Slightly warm paper and ink that sinks a little to thicken hairlines | Smooth white stock and dense black ink so hairlines do not drop out |
| Caution | Pushed into tight display settings the oblique axis and fine serifs turn ragged, and classical calm starts to read as merely old fashioned. | On rough paper or at small sizes the thin strokes disappear, the letters thin out, and poise gives way to plain illegibility. |
