Exclusive: Sony Xperia 1 VIII CAD Renders Reveal Exact Dimensions and Settle the Front-Design Debate

The Sony Xperia 1 VIII has been the subject of weeks of community speculation, with rumours pointing to a redesigned camera module and ongoing debate about whether Sony would adopt a punch-hole display. Today, MyMobiles.com can exclusively reveal the first CAD-based look at the Xperia 1 VIII. These renders are derived from factory CAD data, the same geometry Sony's suppliers are working from, and are not speculation or third-party reconstructions.

These CAD-based renders and the accompanying 360-degree video are a MyMobiles.com exclusive. If you use these images or video, please credit www.mymobiles.com with a link back.

Here is what the renders confirm and what they change.

Renders shown here use neutral finishes. Colours and materials are not defined in the CAD data and should not be read as indicating final Sony colour options.

What changes vs. the Sony Xperia 1 VII

Expand

Mechanically, the Xperia 1 VIII is a close relative of the VII, a careful evolution rather than a reinvention. But there are four changes worth noting.

Width is up 0.4 mm. At 74.4 mm vs 74.0 mm on the VII, the VIII is fractionally wider. This tracks with a larger camera module.

Body thickness is up 0.38 mm. The chassis grows from 8.2 mm to 8.58 mm. Small enough to be imperceptible in the hand, but meaningful inside the phone. It suggests Sony has made room for either a larger primary camera sensor, a bigger vapour chamber, a slightly larger battery, or some combination of the three.

The camera bump is redesigned. The VII's vertically aligned strip is replaced with a redesigned square-style island housing three cameras plus a flash and additional sensors. The bump itself now stands 2.79 mm proud of the body (11.37 mm total thickness), compared with roughly 1.1 mm on the VII.

Height drops 0.1 mm. Functionally identical, but the VIII is technically a hair shorter than its predecessor.

CAD data describes physical geometry. The chipset, battery capacity, sensors, and pricing are not visible in the files and remain subject to future leaks or Sony's eventual announcement.

What the CAD settles: the punch-hole debate

One of the liveliest discussions in the Xperia community over the past month has been whether the VIII would adopt a punch-hole display, breaking with a decade of Sony flagship design, or retain the symmetrical top and bottom bezels that house its front-facing stereo speakers.

The factory CAD data settles it: the Xperia 1 VIII retains the same bezels as the Xperia 1 VII. No punch-hole. The front-facing camera stays in the top bezel. Stereo speakers remain flanking the display. For Xperia purists who consider those speakers one of the line's signature features, this is genuinely good news.

When to expect it

Launch timing is not part of this leak. Based on Sony's consistent Xperia 1 launch schedule over the past three years, these are the dates we expect.

IMEI database listings spotted earlier this year (model prefixes XQ-GE for the flagship, XQ-GH for the companion Xperia 10 VIII) support a similar schedule for 2026, though Sony has not officially confirmed anything.

This is an evolution year for the Xperia 1 line. Sony is not reinventing the design. Instead it is growing the camera footprint slightly and letting the chassis thicken by less than half a millimetre, while keeping the display, bezels, and fundamental layout from the Xperia 1 VII in place. The real upgrades for 2026 will likely come from the chipset and camera sensors, neither of which are part of this CAD leak. We will update this article as more details surface.
