-*** Fullscreen
-I also like the idea of fullscreen-ing when opened by ~Emacs~ or the ~.desktop~ file.
+*** Frame sizing
+It's nice to control the size of new frames, when launching Emacs that can be
+done with ~emacs -geometry 160x48~. After the font size adjustment during
+initialisation this works out to be ~102x31~.
+
+Thanks to hotkeys, it's easy for me to expand a frame to half/full-screen, so it
+makes sense to be conservative with the sizing of new frames.
+
+Then, for creating new frames within the same Emacs instance, we'll just set the
+default to be something roughly 80% of that size.
