Another candidate for this is the number of header lines (also 2). Something
like this:

(defconst bookmark-bmenu-header-lines 2
  "Number of lines used for the *Bookmark List* header.")

(defconst bookmark-bmenu-marks-width 2
  "Number of columns (chars) used for the *Bookmark List* marks column.")
