You could use ChromeOptions and set suitable argument:

options = ChromeOptions()
options.add_argument("--start-maximized")
driver = ChromeDriver(options)

not working for me - the window snapshot show that the size is only 800x600 – Nam G VU Jun 16 '17 at 06:58

@NamGVU check what's the actual screen resolution while executing test - the maximum size is the size of the resolution. I had this problem some time ago because of test being run by process executed as a service. This caused process to be run in Session 0, which has limited capabilities when it comes to screen resolution. Running tests not in a services solves that issue. – Janek Królikowski Jul 12 '17 at 10:45
I run it on ubuntu server; so i guess the screen size set by Xvfb. Thanks to point it out. – Nam G VU Jul 13 '17 at 11:25

This is 2017/12/15 now. `driver.fullscreen_window()` works. – Sraw Dec 15 '17 at 09:41

**driver.maximize_window()** is more comfortable function that works with **selenium chrome driver** in **python**. – Avraham Zhurba Jan 02 '19 at 22:21
This is July 2022, the last comment code works, driver.maximize_window() please credit it. – WLiu Jul 08 '22 at 08:50

Nothing worked for me except:

driver.set_window_size(1024, 600)
driver.maximize_window()

I found this by inspecting selenium/webdriver/remote/webdriver.py. I've never found any useful documentation, but reading the code has been marginally effective.

This is a better answer than the other ones since this one supports all browsers and not just Chrome. – Dror Mar 04 '19 at 13:27

You don't actually need to set the window size first. – Nouman Oct 03 '19 at 15:45
For me, `maximize_window` had no effect. Not doing `set_window_size` kept the window at 800x600, `set_window_size(1920, 1080)` before calling `maximize_window` and when not calling `maximize_window` made the window size 1920x1080. `fullscreen_window` caused my code to hang. I'm using Chrome with `options.add_argument("--headless")`. – Boris Verkhovskiy Apr 17 '20 at 20:41

For MAC or Linux:

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--kiosk");
driver = new ChromeDriver(chromeOptions);

For Windows:

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--start-maximized");
driver = new ChromeDriver(chromeOptions);

--kiosk is only one that worked for me on Mac. Thanks. – n1c9 Jun 22 '17 at 22:27

Keep in mind that once using `--kiosk`, trying to change window size will crash the driver, example (python): `opts = webdriver.ChromeOptions(); opts.add_argument('--kiosk'); driver = ChromeDriver(chrome_options=opts); driver.set_window_size(800, 600)`. Either fullscreen or windowed. – hoefling Oct 09 '17 at 19:34

Based on what Janek answered, this worked for me (Linux):

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument("--start-maximized")

driver = webdriver.Chrome(chrome_options=options)

This didn't work for me on Linux at first, but updated the Chrome driver with `sudo apt install chromium-chromedriver` and it worked then. – Garrett Dec 24 '19 at 18:18

This works for me, with Mac OS Sierra using Python,

options = webdriver.ChromeOptions()
options.add_argument("--kiosk")
driver = webdriver.Chrome(chrome_options=options)

While this code may answer the question, providing additional context regarding how and/or why it solves the problem would improve the answer's long-term value. – Donald Duck Mar 16 '17 at 11:32
