# How to get the \normalsize or \small font baselineskip size?

My documents uses memoir with \OnehalfSpacing and I am trying to get the \normalfont \f@baselineskip to set the \footnotesep with \SingleSpacing.

I could just keep the default value of \footnotesep, but after I setup my document font sizes, the default value of \footnotesep is smaller than \f@baselineskip.

How to get the \normalsize or \small font \baselineskip size and set it to the \footnotesep, for example, something like \setlength{\footnotesep}{\smallsize@baselineskip}?

\documentclass[10pt]{memoir}
\usepackage[english]{babel}
\OnehalfSpacing

\makeatletter
\setlength{\footnotesep}{\f@baselineskip}

\newcommand{\showfont}
{%
(\foreignlanguage{english}
{%
encoding: \f@encoding{},
family: \f@family{},
series: \f@series{},
shape: \f@shape{},
size: \f@size{},
baseline: \f@baselineskip{},
linespacing: \the\baselineskip{}%
})%
}
\makeatother

unknown printer took a galley of type and scrambled it to make a type specimen
book. It has survived not only five centuries, but also the leap into electronic

with the release of Letraset sheets containing Lorem Ipsum passages, and more
recently with desktop publishing software like Aldus PageMaker including
versions of Lorem Ipsum \showfont.
