Samsung quietly adjusted the Galaxy S26's dimensions in the final run of engineering, according to new reports. The changes are tiny on paper, but they could ripple through design, accessories and even battery choices.
Small numbers, noticeable effects
Accessory makers were originally given dimensions of 149.3 x 71.4 x 6.96 mm. The final measurements now appear to be 149.5 x 71.6 x 7.24 mm, with the camera bump rising to 10.44 mm. That means the phone is fractionally taller, wider and thicker than planned — and slightly larger than the Galaxy S25.
Does a few tenths of a millimeter matter? For case manufacturers and precision-fit accessories, yes. Even small size shifts can make a supposedly compatible case feel loose or tight. Users may also notice the extra camera bump thickness when placing the phone on a table.
What this could mean for battery and design
One obvious hope is for a bigger battery behind the slightly expanded shell. Samsung has historically avoided very large batteries in its ultrathin flagships, so that expectation should be tempered. Still, the tweaks give engineers more internal volume to play with — whether for battery capacity, improved cooling or a reworked camera module.

The S26 is expected to keep a flat display and a triple rear camera layout mounted on an oval island, with all buttons on the right side of the frame. Earlier rumors suggested the base model might be called the Galaxy S26 Pro, but that appears to have been dropped.
Chips, cameras and the final word for buyers
As with previous Galaxy launches, Samsung will likely split chipset duties by market, pairing the phone with the Exynos 2600 in some regions and the Snapdragon 8 Elite Gen 5 in others. That, combined with the design tweaks, is what buyers should watch for when preorders and reviews roll in.
- Final reported size: 149.5 x 71.6 x 7.24 mm
- Camera bump thickness: 10.44 mm
- Earlier spec sent to case makers: 149.3 x 71.4 x 6.96 mm
- Expected features: flat screen, triple rear cameras on oval island, right-side buttons
- Likely chipsets: Exynos 2600 and Snapdragon 8 Elite Gen 5
In short, the Galaxy S26's last-minute dimensional changes are small but meaningful — especially for accessory compatibility and internal engineering choices. Expect accessory makers to update designs and for reviewers to call out any real-world differences when the phones land.
