When entering the foldable smartphone market, physical engineering determines whether a hardware design commands attention or gets lost in a crowded market. Reports indicate Apple is aiming to make its first foldable device—tentatively named the iPhone Ultra—the slimmest phone in company history while going head-to-head with established Android competitors.
Quick Summary: Apple’s rumored iPhone Ultra foldable is expected to measure between 4.5mm and 4.8mm when unfolded, undercutting standard slab iPhones while delivering a 7.8-inch inner display. Weighing 230 to 241 grams, it balances ultra-thin engineering with flagship performance, competing directly against top foldables from Samsung, Honor, and Google.
How the iPhone Ultra Dimensions Compare to Apple’s Lineup
Industry reports, including analysis from supply chain analyst Ming-Chi Kuo, indicate that the iPhone Ultra could measure a mere 4.5 mm thick when unfolded. This ultra-slim profile allows Apple’s notebook-style foldable to undercut even the lightweight iPhone Air, which measures 5.64 mm, as well as standard slate designs like the iPhone 17.
When folded shut, the device is projected to measure between 9.0 mm and 9.5 mm thick. That keeps its folded footprint surprisingly close to traditional flagship models like the iPhone 17 Pro Max (8.75 mm), ensuring it fits comfortably in a pocket while offering an expanded 7.8-inch tablet canvas inside.
Dual displays inherently add weight, but leaks suggest the iPhone Ultra will tip the scales between 8.1 and 8.5 ounces (230 to 241 grams). That puts it roughly on par with Apple’s largest single-screen flagship, making the extra screen real estate far more manageable for daily handling.
| Apple Model | Unfolded / Standard Thickness | Weight |
|---|---|---|
| iPhone Ultra (Rumored) | 4.5 – 4.8 mm (Folded: 9.0 – 9.5 mm) | 230 – 241 g (8.1 – 8.5 oz) |
| iPhone Air | 5.64 mm | 165 g (5.82 oz) |
| iPhone 17 | 7.95 mm | 177 g (6.24 oz) |
| iPhone 17e | 7.8 mm | 169 g (5.96 oz) |
| iPhone 17 Pro | 8.75 mm | 206 g (7.27 oz) |
| iPhone 17 Pro Max | 8.75 mm | 233 g (8.22 oz) |
Stacking Up Against Competitor Foldables
While a 4.5 mm unfolded chassis would mark a engineering achievement for Apple, it won’t be the absolute thinnest foldable on the global market. Android manufacturers have spent several generations refining slim hinges and high-density components to push physical limits even further.
Samsung’s Galaxy Z Fold 8 Ultra features an unfolded profile of 4.1 mm, while the Honor Magic V6 leads globally at just 4.0 mm. However, Apple’s projected specs easily outstrip chunkier alternatives such as the Google Pixel 11 Pro Fold and Motorola Razr Fold, placing the iPhone Ultra right in the middle of the competitive space.
| Foldable Device | Unfolded Thickness | Weight |
|---|---|---|
| iPhone Ultra (Rumored) | 4.5 – 4.8 mm | 230 – 241 g (8.1 – 8.5 oz) |
| Samsung Galaxy Z Fold 8 | 4.5 mm | 201 g (7.09 oz) |
| Samsung Galaxy Z Fold 8 Ultra | 4.1 mm | 215 g (7.58 oz) |
| Honor Magic V6 | 4.0 mm | 219 g (7.72 oz) |
| Oppo Find N6 | 4.21 mm | 225 g (7.94 oz) |
| Motorola Razr Fold | 4.7 mm | 243 g (8.6 oz) |
| Google Pixel 11 Pro Fold | 4.8 mm | 245 g (8.64 oz) |
Hardware Expectations and Pricing Trade-Offs
Achieving extreme thinness requires balance, but rumors suggest Apple is aiming to package top-tier hardware into the Ultra’s frame. Anticipated features include an A20 Pro silicon chip, MagSafe support, and a redesigned hinge mechanism engineered to minimize display creasing.
Pricing may present the biggest hurdle for potential buyers. Industry estimates put the iPhone Ultra between $2,000 and $2,500 at launch. For users seeking a crossover between smartphone mobility and tablet utility, Apple’s high-tier pricing model will test consumer willingness to pay a premium for ultra-slim foldable hardware.
Frequently Asked Questions
How thin is the iPhone Ultra expected to be?
Leaks indicate the iPhone Ultra could measure between 4.5 mm and 4.8 mm thick when unfolded. When folded closed, the device is rumored to sit around 9.0 mm to 9.5 mm thick, making it only slightly thicker than standard Pro models.
Is the iPhone Ultra lighter than existing flagship iPhones?
No, the iPhone Ultra is expected to weigh between 230 and 241 grams (8.1 to 8.5 ounces). This makes it comparable in weight to the iPhone 17 Pro Max, largely due to the dual-display construction and hinge components.
What is the estimated price of the iPhone Ultra?
Current leaks suggest the iPhone Ultra could launch with an estimated price point between $2,000 and $2,500, positioning it as an ultra-premium device at the high end of Apple’s smartphone lineup.
