Python: Selenium – Setting Chrome browser size

There are times when running automation on a web browser that you will want to adjust the window size of the browser. The most obvious reason I can think of is some that websites, (mine included) act display differently based on the window size.

For example: Full Size

Reduced size

Notice in the minimized window, my menu list is replaced by accordion button. For the purposes of automation and webscraping, the accordion button is actually easy to navigate than my multi-layered menu.

The code for opening the browser in full screen mode is below: note the line –start-maximized

To open the window in a smaller scale try: window-size=width, length. Play around with the values to get one that works for your screen.
