It's time for a face-off between the two biggest contenders in the tablet category!

The iPad Pro has a slightly larger 12.9" display—as opposed to the 12.3" display found in the Surface Pro 4.

Despite the larger screen, the iPad Pro manages to be lighter than the Surface Pro 4 (1.57 pounds vs. 1.73 pounds for the i5 and i7 models of the Surface).

The iPad Pro is also thinner than the Surface, with a thickness of 6.9 mm vs. the Surface's 8.45 mm.

For the spec geeks out there, the iPad Pro's dimensions are: 305.7 × 220.6 × 6.9 mm, while the Surface Pro 4's dimensions are: 292.10 × 201.42 × 8.45 mm.
