How to set window size for Chrome in Selenium?

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?

ChromeDriver webBrowser = new ChromeDriver(options);

webBrowser.Manage().Window.Size = new Size(400,500);

In Python, you can set window size for Chrome with Selenium as shown below. *-window-size and window-size also work:

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument("--window-size=1024,768")
driver = webdriver.Chrome(options=options)

And in Python, you can also do it with the code below according to the doc:

from selenium import webdriver

driver = webdriver.Chrome()
driver.set_window_size(1024, 768)

*My answer explains it more.

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"
});

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.

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.

#use chrome webdriver

driver = webdriver.Chrome('path to /chromedriver')
driver.set_window_size(1400,1000)

Use this for your custom size:

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

you can change your dimensions as per your requirements.

Approach #1

options = {
      'chromeOptions' => {
          'args' => ['start-fullscreen']
      }
  }

caps = Selenium::WebDriver::Remote::Capabilities.chrome(options)
@driver = Selenium::WebDriver.for :chrome, desired_capabilities: caps

Approach #2

options = {
      'chromeOptions' => {
          'args' => ['window-size=640,480']
      }
  }

caps = Selenium::WebDriver::Remote::Capabilities.chrome(options)
@driver = Selenium::WebDriver.for :chrome, desired_capabilities: caps

Approach #3

max_width, max_height = @driver.execute_script("return [window.screen.availWidth, window.screen.availHeight];")
@driver.manage.window.resize_to(max_width, max_height)

Approach #4

@driver.manage.window.maximize

Approach #5

target_size = Selenium::WebDriver::Dimension.new(1600, 1268)
@driver.manage.window.size = target_size

Approach #6

@driver.manage.window.resize_to(640, 480)

Approach #7

@driver.execute_script("window.resizeTo(640, 480);")

Following chrome options worked for me for headless chrome:

IN JAVA:

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--window-size=1920,1080");
chromeOptions.setHeadless(true);
driver = new ChromeDriver(chromeOptions);
driver.get("your-site");
driver.manage().window().maximize();

selenium-java: 3.8.1

chromedriver: 2.43

Chrome: v69-71

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))
{
    ...
}

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.

Use Dimension Class for controlling window size.

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

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)))

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

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

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

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