Why the iPhone 13 Pro Max weighs 240 grams
The frame is surgical-grade stainless steel rather than aluminium. Steel is roughly three times denser, and the swap accounts for most of the gap between the Pro Max and lighter models.
The rest comes from the battery and the larger glass panels. Apple fitted a 4352 mAh cell, according to teardown measurements, up from 3687 mAh in the iPhone 12 Pro Max.

What the iPhone 13 Pro Max dimensions mean day to day
At 78.1 mm wide, the phone sits at the limit of comfortable one-handed use for most people. Reaching the top-left corner usually means shifting grip or using Reachability.
The payoff is screen area. The 6.7-inch panel gives roughly 20% more usable display than a 6.1-inch iPhone, which matters in maps, spreadsheets and split-view browsing.
In a pocket, the 96.1 cm³ body is noticeable. With a case, most setups cross 250 g.
Case sizing for the iPhone 13 Pro Max
Cases built for the iPhone 12 Pro Max fit the body outline, since height and width match to the tenth of a millimetre. The camera array on the 13 Pro Max is larger, so the cutout often does not line up.
The iPhone 14 Plus shares the 7.8 mm thickness class but differs in width by half a millimetre. Buy cases listed for the 13 Pro Max by name to avoid gaps.
