# Page formats constants

Predefined page formats and their pixel dimensions for Tiptap Pages.

The `PAGE_FORMATS` constant provides a set of predefined page formats (such as A4, A3, Letter, etc.) with real-world dimensions and recommended margins, already converted to pixels. This is useful for quickly setting up the `pageFormat` option or custom layouts in the Tiptap Pages extension.

## Import

```js
import { PAGE_FORMATS } from '@tiptap-pro/extension-pages'
```

## API

```ts
PAGE_FORMATS: {
  [format: string]: {
    id: string
    width: number // in pixels
    height: number // in pixels
    margins: {
      top: number
      right: number
      bottom: number
      left: number
    }
  }
}
```

## Available Formats

Pixel values use standard CSS pixels (one inch is 96 pixels). The constants preserve fractional pixel precision internally; the integers below are rounded for readability.

| ----------- | ---------- | ----------- | ----------------------------------------- |
| **A4**      | 794        | 1123        | 95 / 76 / 95 / 76                         |
