我設定了一個memoir具有以下頁面佈局 (MWE) 的文件：
\documentclass[%
a4paper,
10pt,
twoside,
]{memoir}
%%% Layout the Page %%%
\setstocksize{297mm}{210mm}
\settrimmedsize{\stockheight}{\stockwidth}{*}
\setulmarginsandblock{27.4mm}{*}{1}
\setlrmarginsandblock{24mm}{79mm}{*}
\setmarginnotes{9mm}{50mm}{1em}
\setheadfoot{1.25\baselineskip}{10mm}
\setheaderspaces{*}{8mm}{*}
\checkandfixthelayout[fixed]
\begin{document}
MWE
\end{document}
日誌給了我這個高度和寬度：

我想確定字體和引線尺寸以及尺寸，例如memoir手冊“術語”章節中給出的那樣。所以我猜，對於 10pt 字體和 12pt 引線尺寸來說，這將是 10/12？實際上，如何確定引線尺寸？
最終，我如何確定度量，即文字行的長度？這個 304pt（長度中給出的文字寬度）是否超過 12（點/pica），因此 304/12 = 25.333pc？
