Will a Galaxy S25 case fit a Galaxy S26?
The Galaxy S26 is a bigger phone than the S25. Official sizes for S24, S25 and S26, the Plus and Ultra models, and why cases don’t carry over.

The short answer
No. The Galaxy S26 is taller and wider than the S25 (149.6 mm × 71.7 mm against 146.9 mm × 70.5 mm) with a 6.3-inch screen, so an S25 case is too small.
The S26 Ultra is also a different outline from the S25 Ultra, and thinner. Every generation needs its own case.
Side by side
Official dimensions from the manufacturer. Dimensions alone don’t decide fit: camera position, button placement and cut-outs matter just as much.

What actually changes between them
These are the differences a case has to follow. Any one of them is enough to stop a case sitting flat, covering a button or lining up with the camera.
- The Galaxy S26 is 2.7 mm taller than the Galaxy S25
- The Galaxy S26 is 1.2 mm wider than the Galaxy S25
Galaxy S24 and S25
Closer, but still not the same: the S25 (146.9 mm × 70.5 mm × 7.2 mm) is thinner than the S24 (7.6 mm), and camera and button positions are cut for each model. A loose case is a drop risk, so match the model.
| Spec | Galaxy S24 | Galaxy S25 | Galaxy S26 |
|---|---|---|---|
| Height | 147 mm | 146.9 mm | 149.6 mm |
| Width | 70.6 mm | 70.5 mm | 71.7 mm |
| Depth | 7.6 mm | 7.2 mm | 7.2 mm |
| Screen | 6.2-inch | 6.2-inch | 6.3-inch |
| Charging port | USB-C | USB-C | USB-C |
| Magnetic charging | No magnets | No magnets | No magnets |
Plus and Ultra models
The larger models change too. Compare the official sizes before reusing a case; any difference in height, width or depth, or a moved camera, is enough for a poor fit.
| Spec | Galaxy S25 Ultra | Galaxy S26 Ultra |
|---|---|---|
| Height | 162.8 mm | 163.6 mm |
| Width | 77.6 mm | 78.1 mm |
| Depth | 8.2 mm | 7.9 mm |
| Screen | 6.9-inch | 6.9-inch |
| Charging port | USB-C | USB-C |
| Magnetic charging | No magnets | No magnets |
Magnets and Samsung
Samsung’s S25 and S26 phones have no magnets built in. The Wireless Power Consortium describes them as “Qi2 Ready”: they need a case with magnets to snap onto magnetic chargers. More in which phones have MagSafe.
Why “almost fits” isn’t good enough
A case that nearly fits can press a side button all the time, leave a gap at one corner where the phone can pop out when dropped, or sit on the camera rim so the lenses touch the table. A raised edge around the camera only protects if it surrounds the lenses exactly.
Every YOONIG case is cut for one model, so the print, the openings and the raised edges line up with that phone. If you are not sure which model you have, our guide to finding your exact model takes a minute.
