# Sans serif old-style numerals?

is it possible to get old-style numerals as sans serif? \oldstylenums is with serifs only as far as I see. Or do I need an additional font? (if yes, which one would be suggested?)

Cheers and thanks, Thomas

If you want to stick with the default TeX font, then you could use cfr-lm. This font isn't exactly Computer Modern, but Latin Modern, a modern clone of CM. The package allows to customize the font loading.

\documentclass{article}
\usepackage[sf=oldstyle]{cfr-lm}
\begin{document}
\textsf{1234567890}
\end{document}


or you could switch to old style numerals on demand

\documentclass{article}
\usepackage{cfr-lm}
\begin{document}
\textsf{\oldstylenums{1234567890}}
\end{document}


In XeLaTeX and LuaLaTeX it is much simpler. fontspec changes the default font to Latin Modern anyways, so it is just a matter of adjusting the features for the Sans font (switching on demand with \oldstylenums works as well).

\documentclass{article}
\usepackage{fontspec}
\setsansfont[Numbers=OldStyle]{Latin Modern Sans}
\begin{document}
\textsf{1234567890}
\end{document}


• For cfr-lm: Note that I think \ostyle and \texto{} may be preferable to \oldstylenums because they do not require an encoding switch. Also sf=oldstyle does nothing because you'd get proportional oldstyle figures by default anyway. – cfr Feb 6 '16 at 4:20
• This means, in particular, you can easily mix text with a different style of numbers. For example, \textpl{AB12 3DC} for a UK postcode or US zip, if oldstyle figures are default for the document. (I use this a lot.) Because the fonts are there, there is no need to resort to the supplementary encoding to access these figures. You can just switch families temporarily, which I think is much more satisfactory. At least, I could be mistaken. But that's why I did it that way. Of course, I'm biased ;). – cfr Feb 6 '16 at 4:26
• That looks quite good! Many Thanks! So far I have skipped {Xe,Lua}LaTex but probably I should give them also a try – THX Feb 8 '16 at 8:22

There are quite a few Opentype sans-serif font families out there that feature old-style numerals as an option. However, since they are Opentype fonts, you will need to use either XeLaTeX or LuaLaTeX to access them.

Not knowing anything about your document, I don't think it's helpful to recommend any particular sans-serif font. The following code shows ten different sans-serif fonts I found on my system that feature old-style numerals.

%% Compile with either XeLaTeX or LuaLaTeX
\documentclass{article}
\usepackage{fontspec,array}
\defaultfontfeatures{Numbers=OldStyle}
\begin{document}
\doline{Calibri}
\doline{Calibri Light}
\doline{Latin Modern Sans}
\doline{Linux Biolinum O}
\doline{Optima nova LT Pro}
\doline{Palatino Sans Com}
\doline{Skia Regular}
\doline{TeX Gyre Heros}
\doline{Biome Std Semi Bold}
\end{document}


I recommend looking at http://www.tug.dk/FontCatalogue/sansseriffonts.html for more possibilities.

For the following fonts, no fontspec is required, which means they compile in pdflatex.

Here is Alegreya Sans.
