Change Browser Window Size

Learn how to resize browser window during an Automate session.

Introduction

You can use Selenium commands to resize browser windows in an Automate session. This guide will help you:

1. Maximize browser window during test runtime
2. Resize browser window during test runtime

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

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

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

$web_driver->manage()->window()->maximize();

driver.maximize_window()

driver.manage.window.maximize

$driver->maximize_window();

/* Requires Java Library
You need to import the library org.openqa.selenium.Dimension into your Java project before implementing the resize action in your script. */

Dimension dimension = new Dimension(1920, 1080);
driver.manage().window().setSize(dimension);

driver.manage.window.resize_to(1920, 1080)

driver.Manage().Window.Size = new Size(x, y);

driver.set_window_size(width, height)

driver.manage().window().setSize(x, y);

/* Requires PHP Class
You need to use the class "Facebook\WebDriver\WebDriverDimension" into your PHP test before implementing the resize action in your code. */

$web_driver->manage()->window()->setSize(new WebDriverDimension(1920, 1080));

$driver->set_window_size(1920, 1080);

Exceptions

Safari 10.1 has a known bug where maximizing or resizing the browser window doesn’t work as expected. Refer to StackOverflow and GitHub pages for more information.

This behavior occurs whether the test is run locally on the workstation or on a Selenium Grid. There’s no workaround for this bug at the moment.
