Set Specific Window Width – Selenium Java

Set Specific Window Width

To set specific window width to the browser using Selenium for Java, call driver.manage().window().setSize() method and pass the Dimension object as argument. The Dimension object can be initialized with required width and height. Width is set to the required value, and height is set to the existing height value.

The following is a simple code snippet to set the window size to a width of 800 and keeping the original height.

int width = 800;
int height = driver.manage().window().getSize().height;
driver.manage().window().setSize(new Dimension(width, height));

Example

In the following program, we write Selenium Java code to set the window size to a width of 800.

Java Program

import org.openqa.selenium.*;
import org.openqa.selenium.chrome.ChromeDriver;

public class MyAppTest {
	public static void main(String[] args) {
		//initialize web driver
		System.setProperty("webdriver.chrome.driver", "/usr/local/bin/chromedriver");
		WebDriver driver = new ChromeDriver();
		
		try {
			//get the URL
			driver.get("https://www.tutorialkart.com/");
			//set new dimension to browser window
			int width = 800;
			int height = driver.manage().window().getSize().height;
			driver.manage().window().setSize(new Dimension(width, height));
		} finally {
			driver.quit();
		}
	}
}
