LaTeX - Set small fontsize for the entire document

Question

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.

Answer 1

I think either

\documentclass[10pt]{article}

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

\begin{document}
\small

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