Python Drivers chrome = 57.0.2987.133 chromedriver = 2.27.440174 Code: from selenium.webdriver.chrome.options import Options chrome_options = Options() chrome_options.add_argument(“–window-size=1920,1080”) driver = Chrome(chrome_options=chrome_options)
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)
