Proportional Old-style Figures
Typotheque fonts contain various styles of numerals within one font. Proportional Lining Figures (LF) come standard in all our headline and newspaper fonts. Their proportions are specifically designed to work well with capital letters (for example, in headlines).
The proportional Old-style Figures (OsF) feature changes standard figures to Old-style Figures which work well in running text, as they have the same proportions as lower case letters with their ascenders and descenders.
