On the upper right hand corner of the board should be a small gear or cog symbol. If you run your cursor over it, "Settings" pops up and 2 more symbols. The diagonal 2 headed arrow is the one you want. Click on it and you can change the size of the board by dragging it around. Enjoy!

Thanks! Another question: Do you by any chance know how to set up a board on chess.com where one can practice studying games? I want to play through some master games, but don't know how to get a board where I can move pieces anywhere I want for prctice purposes.
Pretty sure this will do the trick; oh, and of course, you're very welcome.

You can load up FEN and PGN on it or enter the moves by hand. Have fun!
My chess.com "daily chess" screen has always appeared with the board being about 2/3 of the screen on the left and the moves box being the right 1/3. Now it's the opposite: board 1/3 of left screen and moves box 2/3 on the right. How do I get back to the original configuration? I like the board being large. Thanks!
