How can I control Chromedriver open window size?

Question

I'm using Selenium WebDriver for automation and I'm using Chromedriver.

I have noticed that when my driver runs and opens the chrome browser, it opens the browser with a strange size. I tried to fixed it but in vain.

Does anybody know how can I change it?

What language binding are you using? The API provides methods to set windows size regardless which driver you are using (unless you have specific issues with ChromeDriver, then please provide more information in that case). Here's an article you might want to have a look.

Yes, latest window resize is buggy in chromedriver, they say its fixed in 2.28 version , but I got error in that version also . I also end up using command line switches and passing window size as args. – yeshwant singh Apr 20 '17 at 10:52
Thanks! Using ChromeDriver 2.32 and this is the only option that works for a headless variation. C# Windows. driver.Manage().Window.Size does not work. – J-Roel Sep 29 '17 at 21:52

I notice that it seems to have a maximum size that it silently reverts to if you go over. (My machine, 1940 pixels high, but it seems to differ.) – Oddthinking Oct 26 '17 at 03:14
Update: My comment is true for Chrome, but not Firefox. – Oddthinking Oct 26 '17 at 15:22
this notation also works `chrome_options.add_argument('--window-size=768x1024')` – Levon Apr 29 '20 at 20:10
@Levon that format didn't work for me using Selenium .NET, while the format in the answer did work – User Mar 20 '21 at 23:20

chrome_options is now deprecated in favour of "options", so it should be `driver = webdriver.Chrome(options=chrome_options)` – David Faure Jul 11 '22 at 12:31

Use this for your custom size:

driver.manage().window().setSize(new Dimension(1024,768));

you can change your dimensions as per your requirements.

Doesn't seems to work for headless Chrome (version 60). However, @Yonatan Kiron's answer does works – Illidan Jul 31 '17 at 04:48

Puppeteer solution: see [my answer on another thread](https://stackoverflow.com/a/64868797/539149) to do it in using `session.send('Browser.setWindowBounds', {windowId, bounds: {width: width, height: height}})` in a Chrome Devtools Protocol (CDP) session. – Zack Morris Nov 17 '20 at 03:14

C# version of @yonatan-kiron's answer, and Selenium's using statement from their example code.

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.AddArgument("--window-size=1300,1000");

using (IWebDriver driver = new ChromeDriver(chromeOptions))
{
    ...

Try with driver.manage.window.maximize(); to maximize window.

Thanks, but I don't want a full screen, but to fix the window's size by my own size. The Chromedriver for some reason fix the window size when open the browser. – Nimrod_G Apr 30 '14 at 07:21

If you're using the Facebook language binding for php try this:

$driver->manage()->window()->setSize(new WebDriverDimension(1024,768));

In java/groovy try:

import java.awt.Toolkit;
import org.openqa.selenium.Dimension;         
import org.openqa.selenium.Point;

...

java.awt.Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();

Dimension maximizedScreenSize = new Dimension((int) screenSize.getWidth(), (int) screenSize.getHeight());
driver.manage().window().setPosition(new Point(0, 0));
driver.manage().window().setSize(maximizedScreenSize);

this will open browser in fullscreen

chromeOptions.setHeadless(true);
driver = new ChromeDriver(chromeOptions);
driver.get("your-site");

If you are using Clojure and https://github.com/semperos/clj-webdriver you can use this snippet to resize the browser.

(require '[clj-webdriver.taxi :as taxi])

; Open browser
(taxi/set-driver! {:browser :chrome} "about:blank")

; Resize browser
(-> taxi/*driver* (.webdriver) (.manage) (.window) 
  (.setSize (org.openqa.selenium.Dimension. 0 0)))

Use Dimension Class for controlling window size.

Dimension d = new Dimension(1200,800);  //(x,y coordinators in pixels) 
driver.manage().window().setSize(d);

Ruby version:

caps = Selenium::WebDriver::Remote::Capabilities.chrome("chromeOptions" => {"args"=> ["--window-size=1280,960"]})

url = "http://localhost:9515"  # if you are using local chrome or url = Browserstack/ saucelabs hub url if you are using cloud service providers.

 Selenium::WebDriver.for(:remote, :url => url, :desired_capabilities => caps)

resize chrome is buggy in latest chromedrivers , it fails intermittanly with this failure message.

                        unknown error: cannot get automation extension
from timeout: cannot determine loading status
from timeout: Timed out receiving message from renderer: -65.294
  (Session info: chrome=56.0.2924.76)
  (Driver info: chromedriver=2.28.455517 (2c6d2707d8ea850c862f04ac066724273981e88f)

And resizeTo via javascript also not supported for chrome started via selenium webdriver. So the last option was using command line switches.

As long as the total screen resolution you are using is larger than the window size you want to use you can use this (C#):

browserDriver.Manage().Window.Size = windowSize;

If your screen resolution is smaller then you are out of luck. I tried different ways such as:

chromeOptions.AddArgument($"window-size={windowSize.Width},{windowSize.Height}");

Or even importing the move window function to resize a window:

[DllImport("user32.dll", SetLastError = true)]
static extern bool MoveWindow(IntPtr hWnd, int X, int Y, int Width, int Height, bool Repaint);

// Example
MoveWindow(process.MainWindowHandle, 0, 0, windowSize.Width, windowSize.Height, true);

But none of these work. It seems that chrome does something different to prevent the window size from growing bigger than the screen resolution. With Firefox I didn't see this behavior.

From my experience setting size from the webdriver is not always reliable. It might apply it to the viewport only or might fall into other issues (like minimum screen size for that particular webdriver).

See https://w3c.github.io/webdriver/#dfn-set-window-rect

The specification does not guarantee that the resulting window size will exactly match that which was requested. In particular the implementation is expected to clamp values that are larger than the physical screen dimensions, or smaller than the minimum window size.

I'm going to try with setting capabilites to see if it's any better.

The screen resolution of my device was lower than the screen resolution expected by the test.

Workaround that worked for me:

options.EnableMobileEmulation(new ChromiumMobileEmulationDeviceSettings
{
   Height = 1080,
   Width = 1920,
   EnableTouchEvents = false,
   UserAgent = "Responsive"
});
