Samsung Galaxy Z Fold 8 Wide: Full Dimensions — Everything You Need to Know

 The Samsung Galaxy Z Wide Fold is a different shape than any smartphone Samsung has ever made. Not just foldable — wide. Short. Passport-sized when folded. Nearly square when open. Its dimensions define its identity in a way that is unique in the foldable market.

If you are researching the Z Fold 8 Wide dimensions, you are likely trying to answer one of three questions: Will it fit in my pocket? How does it compare to the standard Z Fold 8? What size cases will fit it? This article answers all three — completely, with every leaked measurement explained, contextualized, and visualized.

Every dimension below comes from factory CAD-based renders leaked by OnLeaks on March 25, 2026, and confirmed across Android Headlines, PhoneArena, Tom's Guide, and 9to5Google. These are the most reliable pre-release dimensions available for any unreleased smartphone.

When Folded (Closed)

When Unfolded (Open)

123.9mm tall when folded. To give that number context: a standard credit card is 85.6mm tall. An iPhone 16 Pro is 149.6mm tall. The Galaxy Z Fold 7 is 158.1mm tall. The Z Fold 8 Wide at 123.9mm is 34.5mm shorter than the standard Fold 8 — that is more than an inch and a third.

In practical terms, the Z Fold 8 Wide's folded height is closer to a thick wallet than a phone. For users who carry their phone in a front jeans pocket, this is a transformative difference. The Z Fold 7 at 158mm protrudes visibly from a front pocket — you can see the top centimeter above the pocket line. The Z Fold 8 Wide at 123.9mm sits entirely within most front pockets without visible protrusion.

The height also never changes. This is the Wide Fold's most unusual characteristic: because it folds left-to-right (landscape orientation), the device's height is fixed at 123.9mm whether it is folded or unfolded. You never experience the "tallness" that characterizes standard Z Fold devices.

82.2mm wide when folded. The Z Fold 8 Standard is 72.8mm wide when folded. The iPhone 16 Pro Max is 77.6mm wide. The Z Fold 8 Wide is wider than any current slab phone when folded — comparable to holding two standard-width phones side by side.

One-handed phone use depends on thumb reach. Most adults can span 65–75mm with comfortable one-handed use; the 82.2mm width stretches beyond this range for many users. Reaching the opposite edge of the cover screen one-handed will require hand repositioning or the use of two hands for most users.

However, this width comes with an important benefit: the cover screen's 4:3 aspect ratio at 82.2mm wide produces a display that is almost as wide as a standard 16:9 phone's full screen. Quick interactions — typing a text, checking notifications, replying to email — feel more spacious than they do on a standard narrow foldable.

The Z Fold 8 Wide is the thickest of the 2026 Samsung foldable lineup when folded: 9.8mm versus the Z Fold 8 Standard's 9.0mm and the Z Fold 7's 8.9mm. At 9.8mm, it is approximately the thickness of two standard credit cards stacked, or a thin hardback book's spine.

Compared to first-generation foldables (the original Galaxy Z Fold at 17.1mm, the Z Fold 5 at 13.4mm), 9.8mm represents an extraordinary engineering achievement. The challenge of stacking three display panels, two hinges, and a full-size battery into 9.8mm of thickness is genuinely remarkable.

When unfolded at 4.9mm, the Wide Fold is thinner than most phones (iPhone 16 Pro is 8.25mm). Users who have never used a foldable phone are often stunned by how thin it becomes when open. At 4.9mm, it is barely thicker than a few sheets of cardboard — and spans over 161mm wide with a 7.6-inch display.

When the Z Fold 8 Wide is open, it measures 161.4mm wide × 123.9mm tall. That is wider than it is tall — the device is in landscape orientation even when you hold it normally. This is the defining characteristic that separates the Wide Fold from every other foldable Samsung has made.

The 161.4mm unfolded width is 18.2mm wider than the Z Fold 8 Standard's 143.2mm. To contextualize: the extra 18.2mm is approximately the width of an adult's little finger. It does not sound like much — but spread across a 7.6-inch display, this changes the aspect ratio from 6:5 (tall, like a square-ish tablet) to 4:3 (wide, like an iPad Mini).

The 4:3 aspect ratio has specific advantages over the standard Fold's aspect ratio:

• Video content: Standard 16:9 video has less letterboxing on a 4:3 display. The black bars at top and bottom are narrower, giving you more actual video area.
• Split-screen: Two apps side by side on a 4:3 display each get a panel that is approximately 80mm wide — close to a standard phone's full width. On the standard Fold's 6:5 ratio, each panel is approximately 71mm wide, which is noticeably more cramped.
• On-screen keyboard: The keyboard spans 161mm wide — approximately 18mm wider than the standard Fold 8. Each key is wider and more accurately tappable. Touch-typing at speed becomes more feasible.
• Samsung DeX: In DeX desktop mode, the wider display provides more taskbar space and more comfortable side-by-side window management.

Average front jeans pocket dimensions are approximately 150–160mm tall × 90–100mm wide. The Z Fold 8 Wide at 123.9mm tall fits within this range without protrusion. The Z Fold 8 Standard at 158.4mm sits at the very top of this range — it will protrude 1–2cm above most front pockets.

Back pocket dimensions are typically 130–140mm tall × 100–120mm wide. The Z Fold 8 Wide at 82.2mm wide fits comfortably. The height (123.9mm) also fits within most back pockets. This makes back-pocket carry a genuine option for the Wide Fold — unusual for a foldable.

No credible source has leaked the Z Fold 8 Wide's weight. Based on its dimensions and components, a reasonable estimate is 250–270 grams — lighter than the Z TriFold (309g) but heavier than the Z Fold 8 Standard (~230g). The wide body requires more chassis material, and the dual-hinge mechanism (while similar to the standard Fold's single hinge) adds structural weight.

For context: the Z Fold 7 at 215g was considered "surprisingly light" by Tom's Guide for a foldable. The Wide Fold's estimated 250–270g would be heavier than the Fold 7 but comparable to a heavy slab phone like the Galaxy S26 Ultra (214g) plus a thick case. It is not a light device, but it is not unreasonably heavy for what it is.

This is critical for anyone planning to accessorize the Wide Fold: no existing Z Fold cases will fit it. The dimensions are completely different from every previous Z Fold:

• Z Fold 7 folded: 158.1 × 67.1 × 8.9mm
• Z Fold 8 Standard folded: 158.4 × 72.8 × 9.0mm
• Z Fold 8 Wide folded: 123.9 × 82.2 × 9.8mm

The Wide Fold is 34.5mm shorter than the Fold 8 Standard, 9.4mm wider, and 0.8mm thicker. Case cutouts for cameras, hinges, buttons, and speaker grilles will be completely wrong on any non-Wide-specific case. Using the wrong case risks blocking hinge movement, misaligning camera cutouts, and — in the worst case — applying uneven pressure to the hinge mechanism over time.

Cases need to be engineered specifically for the 123.9 × 82.2mm footprint, the wider hinge span, and the dual-camera placement visible in the leaked CAD renders.

Raw millimeter measurements are hard to visualize. Here are comparisons to objects you already know:

The most useful comparison: the Z Fold 8 Wide folded is nearly identical in footprint to a US passport (125 × 88mm vs 123.9 × 82.2mm). If you can imagine carrying a slightly thicker passport in your pocket, you understand exactly how the Wide Fold will feel when folded.

The inner display measures 7.6 inches diagonally in a 4:3 aspect ratio. Converting: at 4:3, a 7.6-inch diagonal produces a display approximately 152mm wide × 114mm tall — or 6.0" × 4.5". This is meaningfully larger than the 4:3 iPad Mini's effective display area and similar to reading a half-sheet of A4 paper.

For reference, the iPhone Ultra — Apple's competing device — leaks suggest a 7.76-inch inner display at 2,713 × 1,920 resolution, also at approximately 4:3 ratio. The Z Fold 8 Wide's inner display is nearly identical in size to Apple's. Samsung is matching Apple's form factor precisely.

The cover screen at ~5.4–5.5 inches is the Wide Fold's most significant daily compromise versus the standard Fold 8 (6.5"). At 82.2mm wide and 5.4" diagonal, the cover screen has similar width to a standard phone but is shorter than most — reflecting the device's compact 123.9mm height. It is fully functional for notifications and quick tasks but less comfortable for extended cover-screen sessions than the standard Fold's 6.5" cover.
