McDonald’s testing bigger, smaller versions of the Big Mac

Fast food giant McDonald’s is tweaking one of its most iconic menu items.

The burger chain is testing larger and smaller versions of the Big Mac in some of its stores in Ohio and Texas.

The new burgers have new names as well; the larger burger is called the "Grand Mac" while the smaller version is known as "Mac Junior."

McDonald’s says if the new burgers are successful, they could be rolled out in stores nationwide.
