I want to set the font size to 10pt for the ACM article template. But I'm not sure what the correct way to do this is. I guess it is either: \documentclass[sigconf,fontsize=10pt]{acmart} or \documentclass[sigconf,10pt]{acmart}

In the acmart.cls, they have the following code for font size:


  \relax % manuscript
  \or % acmsmall
  \or % acmlarge
  \or % acmtog
  \or % sigconf
  \or % siggraph
   \or % sigplan
   \or % sigchi
  \or % sigchi-a

Thanks for your help. I guess this is a newbie question.

    With \documentclass[sigconf,10pt]{acmart} I get ten point size; the main font is \T1/LinuxLibertineT-TLF/m/n/10. For some reasons known only to ACM, sigconf with fontsize=10pt chooses 9pt.

The correct way is \documentclass[sigconf,10pt]{acmart}. This is the official answer I get from the conference chairs.
