### 4.1.3 Fixed vertical spacing `\paper` variables

Note: Some `\paper` dimensions are automatically scaled to the paper size, which may lead to unexpected behavior. See Automatic scaling to paper size.

Default values (before scaling) are defined in ‘`ly/paper-defaults-init.ly`’.

`paper-height`

  The height of the page, unset by default. Note that the automatic scaling of some vertical dimensions is not affected by this.

`top-margin`

  The margin between the top of the page and the top of the printable area. If the paper size is modified, this dimension’s default value is scaled accordingly.

`bottom-margin`

  The margin between the bottom of the printable area and the bottom of the page. If the paper size is modified, this dimension’s default value is scaled accordingly.

`ragged-bottom`

  If this is set to true, systems will be set at their natural spacing, neither compressed nor stretched vertically to fit the page.

`ragged-last-bottom`

  If this is set to false, then the last page, and the last page in each section created with a `\bookpart` block, will be vertically justified in the same way as the earlier pages.

#### Known issues and warnings

The titles (from the `\header` block) are treated as a system, so `ragged-bottom` and `ragged-last-bottom` will add space between the titles and the first system of the score.

Explicitly defined paper-sizes will override any user-defined top or bottom margin settings.
