@node Paper size and automatic scaling
@subsection Paper size and automatic scaling
values of several @code{\paper} variables are automatically scaled
to the new size. To bypass the automatic scaling for a particular
variable, set the variable after setting the paper size. Note
-that the automatic scaling is not triggered by setting
-@code{paper-height} or @code{paper-width}, even though
+that the automatic scaling is not triggered by setting the
+@code{paper-height} or @code{paper-width} variables, even though
@code{paper-width} can influence other values (this is separate
from scaling and is discussed below). The
@code{set-default-paper-size} and @code{set-paper-size} functions
are described in @ref{Setting paper size}.
The vertical dimensions affected by automatic scaling are
-@code{top-margin} and @code{bottom-margin}. The horizontal

Page breaks are computed by the @code{page-breaking} function. LilyPond
provides three algorithms for computing page breaks,
but the value can be changed in the @code{\paper} block:
@example
-\paper@{
- #(define page-breaking ly:page-turn-breaking)
