# [Tex/LaTex] set font size and line spacing

fontsizeline-spacing

I need a font size of 12 pt and a line spacing of 1.5 lines.

I try:

\documentclass{article}
\usepackage{lipsum}
\linespread{1.5} %regulate line spacing
\renewcommand{\normalsize}{\fontsize{12pt}{0}\selectfont}
\begin{document}
\lipsum[0]
\end{document}


I set the baseline skip in the second {} in \fontsize to 0pt because I think it would interfere with \linespread. On the other hand \linespread appears not to work.

Can you help?

Useless and counterproductive messing with \fontsize. This simpler MWE work as expected:

\documentclass[12pt]{article}
\usepackage{lipsum}
\begin{document}
\lipsum[1]
\end{document}


There a 12pt font and a 1.5 line spacing. What more?
