-In 5.2.1 the @refbugs (line 495 in spacing.itely on master) it
-states:
-
-"@code{layout-set-staff-size} does not change the distance between
-the
-staff lines."
-
-Could we add a sentence:
-"Use instead the pair fontSize = #@var{N}
- \override StaffSymbol.staff-space = #(magstep
-@var{N})
-inside the Staff context to change the size of the font and the
-distance between
-staff lines accordingly."
-
-Actually I found, that the @internalsref{StaffSymbol} at line 481
-sends to an incomplete
-documentation. The property staff-space is not explained here. I
-thought Y-extent might be of
-help, but it is in turn explained by x-space which again is
-missing from the list. Who has the
-knowledge to fix this?

-The default @strong{staff size} is set to 20 points.
-This may be changed in two ways:
+The default @strong{staff size} is 20 points, which corresponds to
+a staff height of 7.03mm (one point is equal to 100/7227 of an
+inch, or 2540/7227 mm). The staff size may be changed in three
+ways:
-To set the staff size globally for all scores in a file (or
-in a @code{book} block, to be precise), use @code{set-global-staff-size}.
+@enumerate
+
+@item
+To set the staff size globally for all scores in a file (or in a
+@code{\book} block, to be precise), use
+@code{set-global-staff-size}:
@example
#(set-global-staff-size 14)
@end example
@noindent
-This sets the global default size to 14pt staff height and scales all
-fonts accordingly.
+The above example sets the global default staff size to 14pt
+(4.92mm) and scales all fonts accordingly.
+
+@item
+To set the staff size for a single score within a book, use
+@code{layout-set-staff-size} inside that score's @code{\layout}
+block:
-To set the staff size individually for each score, use
@example
-\score@{
+\score @{
@dots{}
\layout @{
- #(layout-set-staff-size 15)
+ #(layout-set-staff-size 14)
@}
@}
@end example
+@item
+To set the staff size for a single staff within a system, set the
+staff's font-size and staff-space using units relative to the
+score's default staff size. Using relative units prevents the
+proportion of staff sizes from being altered if the default staff
+size is modified with @code{set-global-staff-size} or
+@code{layout-set-staff-size}.
+
+For example, traditionally engraved chamber music scores with
+piano often used 7mm piano staves while the other staves were up
+to 5/7 as large (if space allowed), or down to 3/5 as large (if
+space was cramped). To achieve the 5/7 proportion, use:
+
+@example
+\score @{
+ <<
+ \new Staff \with @{
+ fontSize = #(magnification->font-size 5/7)
+ \override StaffSymbol.staff-space = #5/7
+ @} @{ @dots{} @}
+ \new PianoStaff @{ @dots{} @}
+ >>
+@}
+@end example
+
+If you happen to know which @code{fontSize} you wish to use, you
+could use the following form:
+
+@example
+\score @{
+ <<
+ \new Staff \with @{
+ fontSize = -3
+ \override StaffSymbol.staff-space = #(magstep -3)
+ @} @{ @dots{} @}
+ \new PianoStaff @{ @dots{} @}
+ >>
+@}
+@end example
+
+To emulate the look of traditional engraving, it is best to avoid
+reducing the thickness of the staff lines.

The Feta font provides musical symbols at eight different
sizes. Each font is tuned for a different staff size: at a smaller size
the font becomes heavier, to match the relatively heavier staff lines.
