I want to use \usepackage[sfdefault]{merriweather}, but without the oldstyle numbers. So, I wanted to change the font for numbers on the sections and chapters or use a similar font (Helvetica, maybe?).

I think that the sectsty package has a solution: \partnumberfont and \chapternumberfont.

Unfortunately, I can not use this package. Also, I cannot use XeTeX or LuaTeX.

Update.: @runartrollet give the solution:


Now I have a correlated question, I don't know if I need to create another topic: There is some way to change all "merriweather" numbers to helvetica numbers?

  • Nowhere. It works with just the plain installation on Mac OS.

  • Welcome to TeX.SX! Please help us help you and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document}.

  • @CostaPR If you want to substitute every numeral in the font with the numerals from a different font, I think you would have to do something very complicated. kerning could be a problem. You could try to make a new question, and maybe some of the super wizards around here could give you a great answer, but I suspect they will just tell you that it shouldn't be done.

  • @CostaPR I found another post which gives an answer on how to replace a symbol with another symbol from another font. It seeks to replace just a single letter, a german one, but you could use the same code to replace all the numbers. Have a look at Importing “ß” from a different font

I don't think this font includes table-numerals(or uppercase-numerals), so you will have to replace the font for the numbers. I would advice against this, as old style numerals do bring a sense of style in. If you want to do it for only the chapter/section-titles, I would change the font for the whole title, not just the number.

Please do not mix fonts like this on the same line, it is really ugly! It is better to change the font for the whole section/chapter -title, have a look at Gonzalo Medina's answer to How to change section/subsection font size? [duplicate] for details on how to change section-style.

Below, I have changed only the font for the number, but I haven't really spent any time finding a font that actaully fits, so it looks quite ugly. You might bea ble to find one that is more fitting. Again, I would adice against this.

\renewcommand{\thesection}{{\selectfont \arabic{section}}} 
\renewcommand{\thechapter}{{\selectfont \arabic{chapter}}} 
  • It looks quite ugly indeed.

  • I will search for another font... I hate these old style numbers on the chapter number...

  • @CostaPR I added a note with a link on how to change the font for the whole section/chapter, which I believe would make it look a lot better than only changing the font for the counter.
