The OnePlus One is a tall handset at 152.9mm versus 146.8mm for the Xperia Z2, but the OnePlus One does house a 5.5-inch display versus the 5.2-inch display in the Xperia Z2. This can be seen in the pictures below, however despite this, the OnePlus One has a similar weight of 162g (Xperia Z2: 163g).
Initial impressions of the OnePlus One point to a very capable handset considering the price. The premium build quality of the Xperia Z2 comes through against the OnePlus One, but then again the Z2 is around £200 more expensive. With handsets like the OnePlus One on the market, it shows more than ever that Sony needs to work ever harder to try and justify a premium over the competition.
