# Single space but double space for paragraph separation

a bit new to LaTeX

My paper is in single-space via \usepackage{setspace}\singlespacing but I have to use double-space for paragraph separation

Any way to do this without having to get rid of \singlespacing?

You may want to use the parskip package:

\documentclass{article}
\usepackage[skip=\glueexpr \baselineskip + 0pt plus 2pt\relax]{parskip}
\usepackage{lipsum}

\begin{document}
\lipsum
\end{document}


The default value for the skip option of parskip is 0.5\baselineskip with the addition of 2pt of stretchability. The example above increases this by 0.5\baselineskip to match your stated requirement.

If you do not need change spacing, remove setspace package and \signglespacing command. Instead play with parskip, like in this example:

\documentclass[12pt]{article}
\usepackage{lipsum}
\setlength{\parskip}{\baselineskip}
\begin{document}
\lipsum
\end{document}
