How to set browser's width and height in Selenium WebDriver?

I'm using Selenium WebDriver for Python. I want instantiate the browser with a specific width and height. So far the closest I can get is:

driver = webdriver.Firefox()
driver.set_window_size(1080,800)

Which works, but sets the browser size after it is created, and I want it set at instantiation. I'm guessing there is an approach along the lines of:

profile = webdriver.FirefoxProfile();
profile.set_preference(foo, 1080)
driver = webdriver.Firefox(profile)

But I don't know what foo would be, and I can't figure out where the docs are.

Q1: is there a way to set width / height at instantiation?

Q2: Where are the reference docs listing all keys usable by profile.set_preference?

These worked for me in Safari...

from selenium import webdriver
...

driver = webdriver.Safari()

then, for...

Window size only:

driver.set_window_size(width, height)

Window size and position:

driver.set_window_rect(x, y, width, height)

*-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)

*This code below also works according to the doc:

from selenium import webdriver

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

<Microsoft Edge>

*-window-size and window-size also work:

from selenium import webdriver

options = webdriver.EdgeOptions()
options.add_argument("--window-size=1024,768")
driver = webdriver.Edge(options=options)

*This code below also works according to the doc:

from selenium import webdriver

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

<Firefox>

*-width and -height also work while width and height don't work:

from selenium import webdriver

options = webdriver.FirefoxOptions()
options.add_argument("--window-size=1024,768")
driver = webdriver.Firefox(options=options)

*This code below also works according to the doc:

from selenium import webdriver

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

Here's a solution that works with both headless and non-headless mode and will start the window with the specified size instead of setting it after:

Chrome:

from selenium.webdriver import Chrome, ChromeOptions

opts = ChromeOptions()
opts.add_argument("--window-size=2560,1440")

driver = Chrome(options=opts)

Firefox:

from selenium.webdriver import Firefox, FirefoxOptions

opts = FirefoxOptions()
opts.add_argument("--width=2560")
opts.add_argument("--height=1440")

driver = Firefox(options=opts)

I tried the below code to set the resolution on mac chrome and windows chrome.

driver.manage().window().setSize(new Dimension(1280, 768));

Use the below code to test the resolution changes:-

Dimension dimension = driver.manage().window().getSize();
LOGGER.info("dimension is " + dimension);

It's easy. Here is the full code.

from selenium import webdriver
driver = webdriver.Chrome()
driver.get("Your URL")
driver.set_window_size(480, 320)

Make sure chrome driver is in your system path.

If you are using chrome

 chrome_options = Options()
 chrome_options.add_argument("--start-maximized");
 chrome_options.add_argument("--window-position=1367,0");
 if mobile_emulation :
     chrome_options.add_experimental_option("mobileEmulation", mobile_emulation)

  self.driver = webdriver.Chrome('/path/to/chromedriver', 
                                  chrome_options = chrome_options)

This will result in the browser starting up on the second monitor without any annoying flicker or movements across the screen.

Here is how I do it in Python with Selenium 2.48.0:

from selenium.webdriver import Firefox
driver = Firefox()
driver.set_window_position(0, 0)
driver.set_window_size(1024, 768)

For me, the only thing that worked in Java 7 on OS X 10.9 was this:

// driver = new RemoteWebDriver(new URL(grid), capability);
driver.manage().window().setPosition(new Point(0,0));
driver.manage().window().setSize(new Dimension(1024,768));

Where 1024 is the width, and 768 is the height.

profile = webdriver.FirefoxProfile()
profile.set_preference('browser.window.width',0)
profile.set_preference('browser.window.height',0)
profile.update_preferences()

write this code into setup part of your test code, before the: webdriver.Firefox() line.

Try something like this:

IWebDriver _driver = new FirefoxDriver();
_driver.Manage().Window.Position = new Point(0, 0);
_driver.Manage().Window.Size = new Size(1024, 768);

Not sure if it'll resize after being launched though, so maybe it's not what you want
