Leak Indicates Samsung’s Galaxy Z Fold7 Might Be the Slimmest Foldable Device Yet

A new leak suggests that the thickness (or, should we say, thin-ness) of the upcoming Samsung Galaxy Z Fold7 will be the slimmest ever seen in a foldable phone. At just 8.2 millimeters when folded, it would presumably measure around 4.1mm when opened. To put that in perspective, a stack of three quarters would be thicker. The existing Z Fold6 measures in at 12.1mm when folded. This information comes from X user Anthony, aka @TheGalox.

After only iterative improvements to the Fold6 last year, foldable fans are hoping for a significant leap forward with this year’s model. We’re also anticipating that 2025 will be the year of ultra-thin phones in general, with the Samsung Galaxy S25 Edge and iPhone 17 Air also set for release.

Whenever I think of futuristic foldables, I envision the folding tablets from Westworld. If the new leak proves true, we’re getting really close to that vision (at least in terms of design aesthetics, not necessarily in terms of advanced technology). So far, the biggest obstacle to ultra-thin phones lies in the cameras. In supposedly leaked renderings of the new ultra-thin foldable, the cameras protrude noticeably from the back of the phone, a recurring challenge in modern smartphone design.

And to temper expectations regarding the latest rumors, earlier leaks had indicated the thickness of the Z Fold7 at 9.55mm when closed, which is still impressively thin. Currently, the world’s thinnest phone is the Oppo Find N5 at 4.21mm when unfolded. If the Oppo Find N5 were any thinner, it wouldn’t even have room for a USB-C charging port. Does that imply a potential return of the Lightning Cable? Alternatively, upcoming foldable smartphones could be designed without any ports, relying entirely on wireless charging and connectivity, though that would come with significant trade-offs.
