LaTeX – Set small fontsize for the entire document


I want to change the font size to small for the entire document. I have searched online. But I am not able to find a reasonable (one line) answer. Is this possible to change the font size of latex document by only one command.? Thanks.

Best Solution

I think either


where you replace 10 with whatever font point-size you want, or, perhaps less likely,


where you replace \small with whatever size-command you want, might be what you are looking for.
