Yes, 12" x 9.6" is more common, but that is a standard ATX size.

B85 -> H87 -> Z87

H87 is basically a full featured board without overclocking. Including things like SLI and Crossfire support. Usually made with decent components.

B class boards are what you would find in your average consumer or business class PC. Basic features and usually adequate components.
