Test step/scenario:
1. Open a browser and navigate to TestURL
2. Maximize the browser

Maximize the browser with C# (.NET):

driver.Manage().Window.Maximize();

Maximize the browser with Java :

driver.manage().window().maximize();

Another way to do with Java:

Toolkit toolkit = Toolkit.getDefaultToolkit();
Dimension screenResolution = new Dimension((int) 
                    toolkit.getScreenSize().getWidth(), (int) 
                    toolkit.getScreenSize().getHeight());

driver.manage().window().setSize(screenResolution);

You can try with this code to maximize chrome window.

ChromeOptions options = new ChromeOptions();
options.addArguments("--window-size=1920,1080");

WebDriver driver = new ChromeDriver(options);

I had the same problem, but the problem can be solved by using following code.

driver.manage().window().fullscreen();

Java

driver.manage().window().maximize();

Python

driver.maximize_window()

Ruby

@driver.manage.window.maximize

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

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

For me, none of the solutions above worked when working with Selenium Web Driver C# + Chrome:

window.resizeTo(1024, 768); - I want to use the whole screen
--start-maximized - it is ignored
driver.manage().window().maximize(); - does not work because it requires some extension and I am not allowed to use Chrome extensions

I managed to get it working using InputSimulator:

var inputSim = new InputSimulator();
// WinKey + UP = Maximize focused window
inputSim.Keyboard.ModifiedKeyStroke(VirtualKeyCode.LWIN, VirtualKeyCode.UP);

The following Selenium Java code snippet worked for me:

driver.manage().window().setPosition(new Point(0,0));
java.awt.Dimension screenSize = java.awt.Toolkit.getDefaultToolkit().getScreenSize();
Dimension dim = new Dimension((int) screenSize.getWidth(), (int) screenSize.getHeight());
driver.manage().window().setSize(dim);

Simply use Window.Maximize() command

WebDriver driver= new ChromeDriver()
driver.Manage().Window.Maximize();

We have observed bug with new driver libraries. You can use slightly old jars which are able to handle new browsers versions.

The main generic option is :-

driver.manage().window().maximize();

You can also use other option for maximizing the browser window.

Example:-

Add below option and pass it to driver:-

    chromeOptions.addArguments("--start-maximized");

The full code will look like below :-

System.setProperty("webdriver.chrome.driver","D:\\Workspace\\JmeterWebdriverProject\\src\\lib\\chromedriver.exe");
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--start-maximized");
driver = new ChromeDriver(chromeOptions);

Toolkit toolkit = Toolkit.getDefaultToolkit();
int Width = (int) toolkit.getScreenSize().getWidth();
int Height = (int)toolkit.getScreenSize().getHeight();
//For Dimension class, Import following library "org.openqa.selenium.Dimension"  
driver.manage().window().setSize(new Dimension(Width,Height));
driver.get("https://google.com");

Try this on safari :-

JavascriptExecutor jse = (JavascriptExecutor)driver;
String screenWidth = jse.executeScript("return screen.availWidth").toString();
String screenHeight = jse.executeScript("return screen.availHeight").toString();
int intScreenWidth = Integer.parseInt(screenWidth);
int intScreenHeight = Integer.parseInt(screenHeight);
Dimension d = new Dimension(intScreenWidth, intScreenHeight);
driver.manage.window.setSize(d);

Chrome driver already support:

Java:

webDriver = new ChromeDriver();
webDriver.manage().window().maximize();

driver.Manage().Window.Maximize();

This works for IE and Firefox. Chrome does not work. There is a bug submitted for this on ChromeDriver project.

Meanwhile, the get around for the chrome is to implement what Joey V. and Coder323 suggested.

ChromeOptions options = new ChromeOptions();
options.addArgument("--start-maximized");
driver = new ChromeDriver(options);

There's an outstanding issue to add this functionality to WebDriver, which can be tracked here: http://code.google.com/p/selenium/issues/detail?id=174

A workaround would be to use the JavascriptExector as follows:

public void resizeTest() {
    driver.Navigate().GoToUrl("http://www.example.com/");
((IJavaScriptExecutor)driver).ExecuteScript("window.resizeTo(1024, 768);");
}

The below line of code would maximize IE, Chrome and Mozilla

driver.manage().window().maximize();

The above line of code and other workarounds mentioned in the post did not work for NodeWebKit browser, so as a workaround i had to use native C# code as mentioned below:

public static void MaximiseNWKBrowser(IWebDriver d)
        {
            var body = UICommon.GetElement(By.TagName("body"), d);
            body.Click();
            string alt = "%";
            string space = " ";
            string down = "{DOWN}";
            string enter = "{ENTER}";
            SendKeys.SendWait(alt + space);
            for(var i = 1; i <= 6; i++)
            {
                SendKeys.SendWait(down);
            }
            SendKeys.SendWait(enter);            
        }

So this workaround basically uses "ALT+SPACE" to bring up the browser action menu to select "MAXIMIZE" from the options and presses "ENTER"

This option is fine for me :

ChromeOptions options = new ChromeOptions();
options.addArguments("start-fullscreen");

This option works on all OS.

I tried many of the answers above, but none work well. My chrome driver version is 2.7 and Iam using selenium-java vesion is 2.9.0. The official document suggests using:

var capabilities = new DesiredCapabilities();
var switches = new List<string>
                       {
                           "--start-maximized"
                       };
capabilities.SetCapability("chrome.switches", switches);    
new ChromeDriver(chromedriver_path, capabilities);

The above also does not work. I checked the chrome driver JsonWireProtocol: http://code.google.com/p/selenium/wiki/JsonWireProtocol

The chrome diver protocol provides a method to maximize the window:

/session/:sessionId/window/:windowHandle/maximize,

but this command is not used in selenium-java. This means you also send the command to chrome yourself. Once I did this it works.

For Webdriverjs (node.js), the following maximizes chrome window.

var webdriver = require('selenium-webdriver');
var driver = new webdriver.Builder().
withCapabilities(webdriver.Capabilities.chrome()).build();
driver.manage().window().maximize();
driver.get('hxxp://localhost:8888');

using System.Windows.Forms;
using System.Drawing;

public static void MaximizeBrowser(this IE myBrowser)
{
    myBrowser.SizeWindow(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height);
}

I used Jim's code, but slightly modified for use with WatiN and C# to maximize the browser.

Through the below code i'm able to maximize the window,

((JavascriptExecutor) driver).executeScript("if(window.screen){
    window.moveTo(0, 0);
    window.resizeTo(window.screen.availWidth, window.screen.availHeight);
    };");

I used this solution

            OpenQA.Selenium.Chrome.ChromeOptions chromeoptions = new OpenQA.Selenium.Chrome.ChromeOptions();
            chromeoptions.AddArgument("--start-maximized");
            OpenQA.Selenium.Chrome.ChromeDriver chrome = new OpenQA.Selenium.Chrome.ChromeDriver(chromeoptions);

Here's what worked for me in C#, firefoxDriver is global to the class:

in the usings:

using System.Drawing;
using System.Windows.Forms;

in the code:

this.firefoxDriver = new FirefoxDriver();
this.firefoxDriver.Manage().Window.Position = new Point(0, 0);
this.firefoxDriver.Manage().Window.Size = new Size(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height);

C# client drivers:

driver = new FirefoxDriver(firefoxProfile);
driver.Manage().Window.Size = new System.Drawing.Size(System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Width+10, System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Height+10);

===> also add a reference to the .NET assembly "System.Windows.Forms"

... the only problem is that it's not positioned correctly
... please comment if you can correct this

You can use something like this (C#):

driver.Manage().Window.Size = new Size(1024, 768);

If you are using the Chrome Driver you can set the capabilities

    var capabilities = new DesiredCapabilities();

    var switches = new List<string>
                       {
                           "--start-maximized"
                       };

    capabilities.SetCapability("chrome.switches", switches);

    new ChromeDriver(chromedriver_path, capabilities);

There is a function that you can use to maximize the window in Python which is window_maximize(). And this is how I'm using it.Hope this helps -

from selenium import selenium
sel = selenium('localhost', 4444, '*firefox', 'http://10.77.21.67/')
sel.start()
sel.open('/')
sel.wait_for_page_to_load(60000)
#sel.window_focus()
sel.window_maximize()
png = sel.capture_screenshot_to_string()
f = open('screenshot.png', 'wb')
f.write(png.decode('base64'))
f.close()
sel.stop()
