# Page settings
To open the **Page settings** dialog: from the menu, select **Format -> Page Settings**....
"Page settings" allows you to adjust the **overall** dimensions of your score such as [page size](#page-size), [page margins](#oddeven-page-margins), and [scaling](#scaling). It contains layout score-wide settings of **currently editing** "Musescore Part" or "Full Score", see also [Musescore Parts](/3/advanced-topics/parts.md) chapter.
Other **overall** size and spacing options:
* **Format -> Style... -> Score, Page, Sizes, System, Measures**, for the Measure item see [Measure](/3/formatting/measure-and-horizontal-spacing.md) chapter, for others see [Layout and formatting](/3/formatting/layout-and-formatting.md) chapter.
The **individual systems pages** specific options:
* See [Breaks and spacers](/3/formatting/breaks-and-spacers.md) chapter
* Stretch commands, see [Layout and formatting](/3/formatting/layout-and-formatting.md) chapter.
* See [Frames](/3/formatting/frames.md) chapter
## Page size
Here you can select the paper format, either by standard name (e.g., Letter or A4), or by specifying the height and width in either mm or inches (use the radio buttons to choose which unit of measurement to use). The initial default page size depends on your localization—in the United States, Letter size paper is standard.
You can also choose to format your music in **Landscape** or **Portrait** orientation using the radio buttons. You can optionally use **Two sided** layout (i.e., book format, with mirror left and right margins for even and odd pages—see [below](#oddeven-page-margins)).
## Odd/Even Page Margins
The **Even Page Margins** and **Odd Page Margins** settings allow you to define the printable area of your pages. Aside from changing the margins around the music on the page, other settings, such as the positions of headers and footers, are calculated relative to the margins defined here.
If the "Two sided" checkbox under "Page Size" is selected, you can set margins differently for mirroring odd and even pages. Otherwise, only one set of margins can be modified, but will apply to all pages.
To display page margins in your score on screen (though not in print), go to **View -> Show Page Margins**.
## Scaling
**Staff space (sp)** : changes the **definition of staff space (sp) itself**. See [Layout and formatting](/3/formatting/layout-and-formatting.md) chapter.
Overriding options for individual object on a score are available:
* **Each** [**Text object**](/3/text/text-styles-and-properties.md) **on a score** has a :Follow staff size: checkbox property set in [the Inspector](/3/basics/inspector.md), see [Text styles and properties](/3/text/text-styles-and-properties.md) chapter.
* Various profiles **"style for text inside certain type of object"** have :Follow staff size" checkboxes set in **Format -> Style... -> Text Styles**, see [Layout and formatting](/3/formatting/layout-and-formatting.md) chapter.
* Each [**Image**](/3/formatting/images.md) **on a score** has a "Size in staff space units" checkbox property set in [the Inspector](/3/basics/inspector.md).
* **\[Please add missing options if you find them]**
## Unit
Select between inches and millimeters for values in this dialog.
## First page number
Sets the number of the first page of the particular score. Page numbers below 1 won't get printed—e.g., setting the first page number to *-1* would result in the first and second page showing no page number, and page number 1 appearing on the third page.
## Apply to all Parts
The **Apply to all Parts** button is available when modifying a **part**, rather than the main score (see [Part extraction](/3/advanced-topics/parts.md)). If you change the page settings of one part and want the rest of the parts to have the same settings, this button will apply the change to all parts in one go.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://handbook.musescore.org/3/formatting/page-settings.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
