Foldable phones have always promised a tablet in your pocket—but the word “pocket” came with a compromise: thickness.
The Galaxy Z Fold 8 changes that. Samsung's new Fold measures just 9.7 mm when folded and 4.5 mm when unfolded, while weighing only 201 g.
For a phone with two displays and a folding hinge, that's remarkably slim
Foldables Have Traditionally Felt Bulky
One of the biggest complaints about earlier Galaxy Z Fold generations was thickness.
For perspective, the Galaxy Z Fold 6 measured 12.1 mm folded and 5.6 mm unfolded. The new Z Fold 8 is only 9.7 mm folded and 4.5 mm unfolded.
That means Samsung has cut roughly:
2.4 mm from the folded thickness — nearly 20% thinner than the Z Fold 6.
That might sound small on paper, but on a device you hold and carry every day, a few millimeters can make a noticeable difference.
Why the Thinner Design Matters
It Feels Less Like Two Phones Stacked Together
At 9.7 mm folded, the Z Fold 8 moves considerably closer to conventional smartphone territory.
Combined with its 201 g weight, Samsung says it's the lightest Galaxy Z Fold model yet.
The result should be a Fold that's easier to carry in a pocket and more comfortable during longer one-handed sessions.
Only 4.5 mm When Open
Unfold the phone and each side becomes exceptionally thin.
At 4.5 mm, the open Z Fold 8 creates a tablet-like experience without the thick chassis normally associated with foldable hardware.
The New Shape Matters Too
Thickness isn't the only change.
Samsung has redesigned the Fold 8 around a 10:16 cover screen and 4:3 main screen, creating a shorter, wider device.
So the improvement isn't simply “thinner.” The entire phone has been reshaped to feel different in everyday use.
Tip: Don't Add the Bulk Back With Your Case
If you're buying the Z Fold 8 because of its thinner design, think carefully about your case.
A huge protective shell can quickly undo the work Samsung did to slim down the phone.
Instead, balance the amount of protection you need with the size you're comfortable carrying.
This is where choosing a slim Z Fold 8 case becomes particularly important.
Look for a case that provides:
- Z Fold hinge protection
- raised camera edges
- screen-edge protection
- strong grip
- thin, lightweight materials
- precise Z Fold 8 fit
The best Z Fold case 2026 should add everyday protection without turning a 9.7 mm foldable back into a bulky device.
The numbers tell the story: 9.7 mm folded, 4.5 mm unfolded and only 201 g.
Samsung hasn't simply made the Galaxy Z Fold 8 thinner—it has made its foldable design considerably easier to carry.
