With an LED panel that's a half-inch larger diagonally than its predecessor, it stands that the SIII would be larger than the SII. And it is, but not by much. At 5.4 x 2.8 inches, it's less than a quarter-inch wider and just a half-inch longer than the SII. Yet with all those extra pixels and cores, the SIII is only 0.34 inches thick, just 0.01 inches thicker than the SII. The newer device did pack on a few ounces, six to be exact. The SII weighs 4.1 ounces versus the SIII's zaftig 4.7 ounces. Both devices protect their LEDs with Corning Gorilla Glass.
