Galaxy S26 Ultra vs S25 Ultra case comparison: are these cases compatible? Both phones have S Pen slots and 200MP cameras, but the dimensions shifted enough to matter for case fit. Shop all Galaxy S Ultra cases at Gorilla Cases.
Dimensional Comparison: S26 Ultra vs S25 Ultra
Galaxy S26 Ultra: 162.8 x 77.6 x 8.2 mm, 218 grams. Galaxy S25 Ultra: 162.8 x 77.6 x 8.2 mm, 218 grams. These measurements are identical — Samsung maintained the same body dimensions year over year. Does this mean cases are interchangeable? Not quite. The camera module arrangement changed between generations, and the S Pen slot position may have shifted fractionally. Gorilla Cases cuts camera cutouts to within 0.3 mm tolerance, meaning generation-specific fit still matters for the 200MP periscope telephoto alignment.
Are S26 Ultra and S25 Ultra Cases Interchangeable?
Physically, an S25 Ultra case will snap onto an S26 Ultra — the outer dimensions are the same. But the camera cutout position for the periscope telephoto is not guaranteed to align perfectly. Samsung repositioned optical elements in the camera module between generations. Using the wrong generation case risks partial camera obstruction, visible in periscope telephoto shots as corner vignetting. Gorilla Cases recommends using model-specific cases for optimal camera performance and precise S Pen slot alignment.
Gorilla Cases S26 Ultra vs S25 Ultra Spec Comparison
S26 Ultra AirShell: 0.9 mm PC, MIL-STD-810G 6.6 feet, S Pen slot preserved, 2.0 mm camera lip, 16 grams. S25 Ultra AirShell: 0.9 mm PC, MIL-STD-810G 6.6 feet, S Pen slot preserved, 2.0 mm camera lip, 16 grams. Difference: Camera cutout precision position — same spec on paper, different physical cutout geometry.
S26 Ultra Fortress: dual TPU-PC, MIL-STD-810G 8 feet, IP54, S Pen, 40 grams. S25 Ultra Fortress: dual TPU-PC, MIL-STD-810G 8 feet, IP54, S Pen, 40 grams. Difference: Camera guard position — same overall protection specs.
S Pen Slot Compatibility
The S Pen slot position in both the S26 Ultra and S25 Ultra is at the bottom-right corner of the device. The slot diameter has not changed. However, the precise depth and entry angle are calibrated to each phone's S Pen slot geometry. Using an S25 Ultra case on an S26 Ultra may create slight misalignment in the S Pen punch-through that makes S Pen reinsertion awkward. Model-specific cases ensure perfect S Pen slot alignment.
Should S25 Ultra Users Buy New Cases for S26 Ultra?
If you upgraded from S25 Ultra to S26 Ultra: yes, get a new case. The camera module and S Pen slot geometry justifies model-specific precision. If you're staying on S25 Ultra: the full Gorilla Cases S25 Ultra line — AirShell, Fortress, CrystalShield, VaultFolio — remains available. The S25 Ultra with Google's seven-year — wait, Samsung's four-year update commitment — is still a well-supported device in 2026.
