Apple’s upcoming iPhone 18 Pro Max is expected to be thicker than the iPhone 17 Pro Max due to increased depth around the camera plateau. YouTuber Vadir Yuryev behind the Max Tech channel shared numbers based on iPhone 18 Pro Max dummy units. Yuryev also compares an iPhone Ultra dummy unit to iPhone 17 Pro Max.

iPhone 18 Pro will feature an upgraded camera system

According to Yuryev, both the camera plateau and camera lenses will protrude further on the iPhone 18 Pro Max compared to the iPhone 17 Pro Max.

• 17 Pro Max thickness from cameras: 12.92mm
• 18 Pro Max thickness from cameras: 13.77mm
• 17 Pro Max thickness from plateau: 11.23mm
• 18 Pro Max thickness from plateau: 11.54mm

Apple officially lists the depth as 8.75mm for both the iPhone 17 Pro and iPhone 17 Pro Max, based on the body of the phone without the camera system measured. This is also how the iPhone Air has the thinnest measurement at 5.64 mm.

The increased thickness is expected to be due to the upgraded camera system on the iPhone 18 Pro line this fall.

At a glance, it will likely be difficult to spot the change in depth, and the iPhone Air line gives the Pro line more room to trade sleekness for performance.

iPhone Ultra compared to iPad mini

Vadir also compares iPhone Ultra (rumored name for Apple’s foldable display model coming this year) dummy units to existing Apple products:

Look out for a hands-on video with these dummy units from Max Tech later today.

Apple’s first foldable display iPhone is expected to include the ability to run two iPhone apps side-by-side. While some rumors have suggested it may launch later than the iPhone 18 Pro this fall, the latest suggests no significant delay.
