# getPageDisplaySize

> Get the display size of the current page.

<Note>
  This API returns the display size of the currently opened page and is intended for current-page element operations such as `batchUpdatePageElements`, `insertPageElements`, and `modifyPageElements`.
  When these APIs operate on the current page, call `getPageDisplaySize` to get the current page display size instead of calling [`PluginFileAPI.getPageSize`](/en/api-reference/supernote-plugin/plugin-file-api/get-page-size), otherwise the position data may not match.
</Note>

```ts theme={null}
static getPageDisplaySize(): Promise<APIResponse<Size>>;
```

**Returns**

* [`APIResponse<Size>`](/en/api-reference/supernote-plugin/types/api-response): `result` is the display size of the current page. See [`Size`](/en/api-reference/supernote-plugin/types/size)

## Example

```ts wrap theme={null}
import { PluginCommAPI } from 'sn-plugin-lib';

/**
 * Example: get the display size of the current page.
 */
export async function exampleGetPageDisplaySize() {
  const res = await PluginCommAPI.getPageDisplaySize();
  if (!res.success) {
    console.log('getPageDisplaySize failed', res.error);
    throw new Error(res.error?.message ?? 'getPageDisplaySize call failed');
  }
  console.log('getPageDisplaySize result', res.result);
  return res.result;
}
```
