The Samsung Galaxy Z Fold 7 is poised to mark a significant evolution in foldable smartphone design, particularly in terms of slimness and portability compared to its predecessor, the Galaxy Z Fold 6. Multiple leaks and reports leading up to the official launch in July 2025 suggest that Samsung has made remarkable strides in reducing the device’s thickness and weight, while also enhancing screen size and usability.
Thickness and Weight Reduction
The most striking difference between the Galaxy Z Fold 7 and the Z Fold 6 lies in their thickness. The Z Fold 6 measures approximately 12.1mm when folded, which, while competitive at its launch, was considered bulky compared to some rivals. In contrast, the Z Fold 7 is rumored to be just about 8.9mm thick when folded, with some reports specifying a range between 8.2mm to 9.5mm depending on whether the camera bump is included. When unfolded, the Fold 7 could be as thin as 4.2mm, a dramatic reduction from the Fold 6’s 5.6mm thickness.
This reduction of around 3.2mm in thickness is unprecedented for a single generation of foldable phones and would make the Z Fold 7 Samsung’s thinnest foldable device to date. The weight is also expected to drop, with the Fold 7 weighing approximately 215g, which is about 24g lighter than the Fold 6. This makes the device not only slimmer but also notably lighter, enhancing pocketability and everyday comfort[1][2][3].
Design and Display Enhancements
While the overall design language remains consistent with flat edges and squared corners, the Fold 7 introduces a wider and larger display experience. The external cover screen is expected to grow from 6.3 inches on the Fold 6 to 6.5 inches on the Fold 7, improving usability and moving away from the “skinny remote-control” feel of previous models. The internal foldable screen is anticipated to expand from 7.6 inches to around 8.2 inches, adopting a squarer aspect ratio that better supports multitasking and productivity.
Samsung is also expected to maintain its high standards for display quality, with Dynamic AMOLED 2X panels featuring smooth refresh rates between 1Hz and 120Hz, ultra-thin glass on the inner screen, and Gorilla Glass Victus 2 protection on the outer screen. These improvements not only enhance the visual experience but also contribute to the device’s sleek profile by allowing thinner, more durable screen layers[1][3].
Technical and Functional Considerations
The pursuit of slimness has led to some trade-offs and innovations. For instance, there are rumors that Samsung might remove the stylus digitizer layer in the Fold 7 to achieve a thinner display, potentially impacting S Pen support. However, other reports suggest Samsung could update the S Pen technology to remain compatible with the slimmer design.
Additionally, despite the thinner body, the Fold 7 is expected to retain a 4,400 mAh battery capacity, balancing slimness with battery life. Camera upgrades are also on the horizon, with a rumored 200MP main sensor and a 10MP wide-angle front camera, powered by the Snapdragon 8 Elite chipset, ensuring the Fold 7 remains a flagship contender not just in design but also in performance.
Conclusion
The Galaxy Z Fold 7 represents a substantial leap forward in foldable smartphone design, chiefly by being significantly slimmer and lighter than the Z Fold 6. Samsung’s ability to reduce thickness by over 3mm while expanding screen sizes and maintaining high-end features signals a maturation of foldable technology. This evolution promises a more pocket-friendly, elegant device that does not compromise on screen real estate or performance, potentially setting a new benchmark for foldables in 2025.
