## The Short Answer

No, your S25 Ultra case won't work. The phones look nearly identical, but Samsung changed just enough to make your old case a poor fit.

## Why Your Case Won't Fit

It comes down to numbers. The [S26 Ultra](https://www.samsung.com/us/smartphones/galaxy-s26-ultra/) is:
- **0.8mm taller** than the S25 Ultra
- **0.9mm narrower**
- **0.3mm thinner**

That might not sound like much, but case manufacturers design tolerances in fractions of millimeters. A case that's 0.9mm too wide creates noticeable wobble.

## It's Not Just the Size

Samsung also redesigned several elements:

**The camera bump is different.** The S26 Ultra has a new raised camera island layout. If you use your old case, the camera cutout won't line up properly—your lenses might not be fully protected.

**The corners are rounder.** Samsung gave the S26 Ultra more ergonomic, curved corners. Cases designed for the S25 Ultra's sharper edges will leave gaps.

**Buttons moved slightly.** You might find yourself pressing through case material instead of through the cutouts.

**The S Pen slot shifted.** An S25 case could partially block your stylus.

## What About Screen Protectors?

Same story—they won't transfer. The S26 Ultra's display is slightly different in size and curvature. Your old screen protector would be misaligned, leaving edges unprotected.

## Where to Buy S26 Ultra Cases

S26 Ultra cases were available immediately at launch from all the major brands. Look for options from Samsung, OtterBox, Spigen, [ZAGG](https://www.zagg.com/), ESR, and others. Make sure whatever you buy specifically says "Galaxy S26 Ultra"—don't trust anything marketed as "fits most Galaxy Ultra models."
