With the iPhone Duo just weeks away, a comparison with the iPad mini reveals striking similarities in form factor. The iPhone Duo functions as a two-in-one device: a traditional iPhone on the outer display and an iPad mini-like experience when unfolded. Official Apple dimensions show the iPhone Duo at 4.64 inches tall and 6.48 inches wide, while the iPad mini measures 5.3 inches by 7.69 inches.

Despite the chassis difference, screen sizes are closer than expected due to the iPhone Duo's minimal bezels. The folding device features a 7.6-inch display versus the iPad mini's 8.3-inch screen. Video comparisons from Adrián Santos and Dylan McDonald on X illustrate the side-by-side scale, including a mockup against the classic 7.9-inch iPad mini.

The device aims to replicate the compact tablet experience in a pocketable foldable.
