Bloomberg's Mark Gurman has reported multiple times that the first Apple foldable will be similar to Samsung's Galaxy Z Fold series. It will also come close to the book-style foldable's design in terms of thickness and crease visibility. According to industry analyst Ming-Chi Kuo , the iPhone Fold could measure between 9- and 9.5mm when folded, and around 4.5- to 4.8mm when unfolded.
