iPhone Duo vs iPhone 18 Pro Max
Which one shows video bigger? Drawn to physical scale.
For 16:9 video, the iPhone Duo shows a picture about 7.1″ across and the iPhone 18 Pro Max about 5.9″. The iPhone Duo shows it 1.47× larger by area.
Same brand, two shapes. The 18 Pro Max has the taller screen, but tall is wasted on 16:9 video: rotated to landscape it fits a strip barely wider than the Duo shows while held normally. Unfold the Duo and widescreen content gets dramatically bigger.
