Go to your board settings. On your board game page at the right bottom select settings this will bring you to your bord and change the settings.
Screen size

Thanks, I toggled board sizes. I recall some sort of zoom feature that might be a chrome setting. In any event, it's workable.

Holy Cow. I held the curser over Play/Online Chess and the web page got huge, like tapping on my phone but I'm on my computer.

How do you go to the board settings

I pushed a button and my screen zoomed in on chess.com on my Chrome browser. I dont know if this is a chess.com feature of a Chrome feature. Now the board takes up 105% of my screen. How do I undo it?
