Apple’s latest iPhone Air is the slimmest iPhone to date. However, speculation suggests it won’t maintain that distinction for long. Here’s what to anticipate with next year’s even sleeker iPhone Fold.
## Anticipated iPhone Fold to Be 20% Thinner Than iPhone Air When Opened
It’s never too soon to begin contemplating next year’s iPhones. The highly anticipated feature of the fall 2026 lineup will be Apple’s debut foldable model.
Tentatively named the ‘iPhone Fold,’ this could be the most fundamentally innovative iPhone design that Apple has produced.
Among the speculated upgrades, it is expected to be considerably thinner than the new iPhone Air.
Here’s a detailed comparison:
– **iPhone Air:** 5.6mm
– **iPhone Fold:** **4.5-4.8mm** when opened, 9-9.5mm when closed
This 4.5-4.8mm estimation was shared by analyst Ming Chi-Kuo earlier this year. While Apple has likely finalized the specifications since then, Kuo’s projections remain a reliable point of reference.
According to Kuo’s analysis, the iPhone Fold will be approximately one full millimeter slimmer than the iPhone Air when in operation and opened up. That represents a significant 20% reduction compared to an already extremely slim iPhone Air.
## iPhone Series: Thickness Comparisons
For some context, here’s how the other models in the current iPhone series stack up:
| Model | Depth |
|———————-|———–|
| iPhone 17 | 7.95mm |
| iPhone Air | 5.64mm |
| iPhone 17 Pro | 8.75mm |
| iPhone 17 Pro Max | 8.75mm |
| iPhone Fold (opened) | 4.5-4.8mm |
| iPhone Fold (closed) | 9-9.5mm |
Reducing about 20% off the dimensions of the already very slim iPhone Air will be remarkable. Additionally, Apple managing to give the iPhone Fold a thickness similar to the iPhone 17 Pro when folded will also be notable.
Essentially, you’ll have an iPhone that feels very similar to current Pro models when stored in your pocket, and exceedingly slim when opened and in use.
I have many positive remarks about this year’s iPhone series. However, I am already quite eager to discover what Apple has planned for users with its long-awaited foldable device.
