SquarePixel writes: In theory, the pigs of Angry Birds should be no different from those featured in Bad Piggies, Rovio's recently released spinoff. But according to Wired's Rhett Allain, there are some differences — most notably, their size. Using Newtonian physics to calculate their real-world size, Allain determined that each pig in Bad Piggies would have a girth of about 96 centimeters. That's 83 percent the size of the original Angry Birds pigs, which measured at around 1.16 meters wide. The slingshot, in case you were wondering, would stand at about 4.9 meters tall.
