Quotes from Chen We chose a notch-less screen with an 18:9 aspect ratio, and minimal bezels. Our device's footprint is smaller than most other 6-inch 18:9 phones, like the Nokia 7 Plus or Moto Z3. This doesn’t just reduce physical size, it also improves the typing experience. It's a 18:9 ratio in 6", in another word it's the same panel as a 5.4-5.5" screen in 16:9. The screen is bigger due to less bezels. In measurements the device is quite narrower and slightly shorter than the Moto Z2 Play. Thinking this way, it's a 5.4" of the traditional 16:9 ratio. P.S: Being quite smaller than the Xperia XA2 Plus, which quite some users are happily using SFOS upon. Xperia 157 x 75 x 9.6 mm Z2 Play 156.2 x 76.2 x 6 mm Moto Z 153.3 x 75.3 x 5.2 mm Galaxy S7 142.4 x 69.6 x 7.9 mm Sharp Aquos 131 x 67 x 10 mm I don't know what "quite narrower" means, but hopefully the device is as small as possible. I've never ventured past 5 inch 16:9 phones because they're already the max size I can handle. I think Chen also said it's smaller than the Moto Z, so I think my estimations are accurate. Roughly 150x70x10. Push for smaller Chen, PLEASE! @chenliangchen I would be very impressed if the device is under 70mm wide and under 150mm tall, that would be a feat. Thickness I don't mind too much, I know the keyboard will take some space I also included the dimensions for the Galaxy S7 and the Sharp Aquos for comparison. Those are true compact phones in today's market
