Unfolded · October 2026
iPhone Duo vs iPad mini
Unfolded, iPhone Duo's 7.6-inch screen has about 86% of the area of iPad mini's 8.3-inch screen, in a body 30.8 mm less wide and 17 mm less tall (both held landscape) and 39 g lighter, that still folds to phone size.
Side by side
The open Duo next to iPad mini.
Held landscape, the open Duo is 164.6 mm wide, 30.8 mm less than an iPad mini held the same way, and 17 mm less tall. Its screen is close to square (long side 1.42 times the short side) where iPad mini's is 1.52, so the Duo shows a page of a book or a web page at a similar width but less of it at once.
The bigger practical difference is what happens when you close it: the Duo folds to 117.8 × 84.1 mm and works as a phone on its 5.4-inch outer screen. iPad mini has no phone number of its own (cellular models carry data only) and does not fit a trouser pocket.
