There are many, many unanswered questions surrounding the Nintendo Switch (aka. Project NX) after its brief unveiling this morning. The biggest? We still don’t know the actual dimensions of the system—which includes a tablet screen and detachable Joy-Con controllers. In the absence of official information, we’ve analyzed high-quality images of the system distributed by Nvidia to estimate those dimensions. That analysis shows the Nintendo Switch has a roughly 6.5″ screen and individual controllers slightly smaller than those on the NES.

Our photographic analysis of the Switch’s dimensions hinges on a single visual reference point: the analog sticks on the controllers. On the Wii U, Xbox One, and PS4, the top surface of the analog stick measures 17 to 18 mm in diameter at the widest point. That seems to be a comfortable sweet spot that all the console manufacturers have converged upon. It’s possible the Switch has thrown this convention out the window and sports a much smaller or larger analog pad, but we doubt it.
