# Page.setViewport() method
`page.setViewport` will resize the page. A lot of websites don't expect phones to change size, so you should set the viewport before navigating to the page.
In the case of multiple pages in a single browser, each page can have its own viewport size.
**Signature:**
```typescript
class Page {setViewport(viewport: Viewport): Promise< void > ;}
```
## Parameters
| Parameter | Type | Description |
| --- | --- | --- |
| viewport | [Viewport ](./puppeteer.viewport.md ) | |
**Returns:**
Promise< void>
## Remarks
Argument viewport have following properties:
- `width` : page width in pixels. required
- `height` : page height in pixels. required
- `deviceScaleFactor` : Specify device scale factor (can be thought of as DPR). Defaults to `1` .
- `isMobile` : Whether the meta viewport tag is taken into account. Defaults to `false` .
- `hasTouch` : Specifies if viewport supports touch events. Defaults to `false`
- `isLandScape` : Specifies if viewport is in landscape mode. Defaults to false.
NOTE: in certain cases, setting viewport will reload the page in order to set the isMobile or hasTouch properties.
## Example
```ts
const page = await browser.newPage();
await page.setViewport({
width: 640,
height: 480,
deviceScaleFactor: 1,
});
await page.goto('https://example.com');
```
