One of the first questions when a new foldable arrives is how much its size changed and whether old accessories still fit. Here is how the Galaxy Z Fold 8 compares with the Galaxy Z Fold 7 on dimensions. The Galaxy Z Fold 8 and Fold 7 are close in overall footprint, but even small changes to camera placement, button position or thickness mean a Fold 7 case is not guaranteed to fit the Fold 8. For a correct fit, choose a case cut specifically for your model. Fold 8 phone specifications that Samsung has not finalized are described as expected or reported rather than confirmed.
Known Fold 7 dimensions
The Galaxy Z Fold 7 measures about 158.4 by 143.1 by 4.2 mm unfolded and 158.4 by 72.8 by 8.9 mm folded, weighing roughly 215 grams, with an 8.0-inch main display and a 6.5-inch cover screen. Those are confirmed figures for the 2025 model.
It set a notably thinner and lighter baseline than earlier Folds.
What to expect from the Fold 8
Samsung has not published every final measurement for the Fold 8 at the time of writing, so treat its exact dimensions as expected or reported. Generation-to-generation changes on the Fold line are usually small, often within a millimeter or two, which is enough to affect a tight-fitting case even when the phones look identical.
Why small changes affect case fit
Cases are cut to tight tolerances around the cameras, buttons and hinge. A shift of even a millimeter in camera placement can mean a Fold 7 case blocks a lens or leaves a gap on the Fold 8. That is why a model-specific Fold 8 case is the safe choice.
The takeaway
The two phones are close in size, but close is not the same as identical. Buy a case and screen protector made for the exact model you own rather than assuming last year's fits.
