-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
+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.
