The Galaxy Z Fold 7 is incredibly thin

The Galaxy Z Fold 7 is the thinnest Fold ever made by Samsung. At just 4.2mm thin when open and 8.9mm thick when folded, it’s slimmer than most smartphones, let alone foldables. And despite its compact profile, it still manages to pack in all the power, multitasking, and flagship features you’d expect.

Weighing only 215 grams, the Fold 7 feels significantly lighter in hand — a big improvement for those upgrading from earlier models like the Fold 6 (239 grams) or Fold 5 (253 grams). In fact, it is lighter than the Galaxy S25 Ultra (218 grams). The new Fold is not just thinner, it’s more comfortable to use, whether you’re typing in Flex Mode or watching videos on the unfolded 8-inch display.

When a phone is just 4.2mm thick, it’s natural to have concerns about its strength and durability. To that end, Samsung has reinforced the Galaxy Z Fold 7 with a new Armor Flex Hinge, engineered for smoother folding and improved durability. The phone has a Grade 4 titanium lattice structure that adds to its strength without making it heavier.

Additionally, the Fold features a 50% thicker Ultra Thin Glass layer under the main screen, improving both strength and touch feel. Corning’s Gorilla Glass Ceramic 2 protects the cover screen, while you’ll find the Gorilla Glass Victus 2 on the rear panel for added drop and scratch resistance. The frame is made up of Advanced Armor Aluminum for lightweight structural rigidity.

With the Galaxy Z Fold 7, Samsung has clearly listened to its audience. People wanted a thinner, lighter foldable without sacrificing durability, and that’s exactly what they delivered. Stay tuned for more hands-on impressions, camera details, feature breakdowns, and an in-depth review.
