-All layout dimensions are displayed in staff spaces, regardless of
-the units specified in the @code{\paper} or @code{\layout} block.
-For example, @code{paper-height} has a value of 59.75 staff
-spaces, using the default staff size of 20 points, which is
-equivalent to 148 millimeters, the height of @code{a6} paper in
-landscape orientation. The pairs (@var{a},@var{b}) are intervals,
-where @var{a} is the lower edge and @var{b} the upper edge of the
-interval.
+In this case, one @code{staff-space} is approximately equal to
+1.757mm. Thus the @code{paper-height} measurement of 59.75
+@code{staff-spaces} is equivalent to 105 millimeters, the height

+Force the number of systems. This can help in two ways. Just
+setting a value, even the same value as the number of systems
+being typeset by default, will sometimes cause more systems to
+be fitted onto each page, as an estimation step is then bypassed,
+giving a more accurate fit to each page. Also, forcing an actual
+reduction in the number of systems may save a further page. For
+example, if the default layout has 11 systems, the following
+assignment will force a layout with 10 systems.
